    Metallutvinning med fokus på zinkfrån avfallsflygaska med hjälp avsura processvatten2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syftet med projektet är att behandla flygaskan med hjälp av surt processvatten för att utvinna olika metaller, som zink, så att det sedan kan deponeras på ett enklare och billigare sätt, samt även at utveckla en metod för att utvinna mer zink med minsta möjliga andel surt processvatten (5 % HCl). Olika metaller med fokus på zink studerades i labbskala på Högskolan i Borås. Flygaskan och det sura processvattnet som har använts i denna studie är från Renova ABs anläggning. Resultatet visar att vid behandling av flygaskan med surt processvatten var den maximala mängden zink som utvanns 88% under de olika försöken som gjordes i labbet. Det finns olika faktorer bakom resultatet, såsom halten av surt processvatten, pH, blandningstiden och askans elementsammansättning, vilka kan påverka halten utvunnen zink.

    Ethanol production by Mucor indicus and Rhizopus oryzae from rice straw by separate hydrolysis and fermentation2009Inngår i: Biomass and Bioenergy, ISSN 0961-9534, E-ISSN 1873-2909, Vol. 33, nr 5, s. 828-833Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Rice straw was successfully converted to ethanol by separate enzymatic hydrolysis and fermentation by Mucor indicus, Rhizopus oryzae, and Saccharomyces cerevisiae. The hydrolysis temperature and pH of commercial cellulase and β-glucosidase enzymes were first investigated and their best performance obtained at 45 °C and pH 5.0. The pretreatment of the straw with dilute-acid hydrolysis resulted in 0.72 g g-1 sugar yield during 48 h enzymatic hydrolysis, which was higher than steam-pretreated (0.60 g g-1) and untreated straw (0.46 g g-1). Furthermore, increasing the concentration of the dilute-acid pretreated straw from 20 to 50 and 100 g L-1 resulted in 13% and 16% lower sugar yield, respectively. Anaerobic cultivation of the hydrolyzates with M. indicus resulted in 0.36-0.43 g g-1 ethanol, 0.11-0.17 g g-1 biomass, and 0.04-0.06 g g-1 glycerol, which is comparable with the corresponding yields by S. cerevisiae (0.37-0.45 g g-1 ethanol, 0.04-0.10 g g-1 biomass and 0.05-0.07 glycerol). These two fungi produced no other major metabolite from the straw and completed the cultivation in less than 25 h. However, R. oryzae produced lactic acid as the major by-product with yield of 0.05-0.09 g g-1. This fungus had ethanol, biomass and glycerol yields of 0.33-0.41, 0.06-0.12, and 0.03-0.04 g g-1, respectively.

    Anbud: Faktorer och förbättringsmöjligheter i anbudsprocessen2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Rapporten visar hur omfattande anbudsprocessen är och vilka faktorer man bör beakta för attlämna ett vinnande anbud. Den beskriver de olika delarna i anbudsprocessen och gör endjupare analys av några av de viktigaste faktorerna. Anbudslämning handlar inte bara om attlämna pris på vad något kommer att kosta. Eftersom bolagen sällan är ensamma gäller de atthitta vägar och lösningar som gör att anbudet blir konkurrenskraftigt. Alternativa tekniskalösningar, materialval, val av UE eller en snygg presentation är faktorer som kan göra anbudetvinnande.Rapporten är skriven tillsammans med RO-Gruppen och en enkät ligger som grund tillanalysen. Målsättningen var att beskriva RO-Gruppens arbete och finna eventuell möjlighettill förbättring och effektivisering i arbetet.Då FFU, beställare och upphandlingsform varierar är det svårt att alltid följa en och sammamall utan en öppenhet och flexibilitet i arbetet krävs för att kunna lämna ett vinnande anbud.Erfarenhet visade sig vara en stor och avgörande faktor, såväl enligt litteratur, somenkätundersökningen.

    Sociala medier: ett verktyg för en mer hållbar klädkonsumtion2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Sammanfattning Dagens klädkonsumtion sammankopplas ofta med hållbarhet framförallt gällande materialets miljöpåverkan och arbetsförhållanden i produktionen. Kläder massproduceras och tillverkas därför inte med hållbarhet i fokus. Företag kommer undan med att erbjuda icke hållbara kläder eftersom konsumenter främst fokuserar på utseende och pris istället för hållbarhet i sitt konsumentbeteende. Tidigare forskning beskriver att konsumenter har en negativ attityd till klädindustrins påverkan på hållbarhet men att de inte konsumerar hållbart på grund av kunskapsbrist. Denna brist på kunskap skapar ett gap mellan konsumenters attityd till hållbar klädkonsumtion och deras konsumentbeteende. Problemet med ökad konsumtion och hållbarhet kan kopplas till sociala medier. Sociala medier används bland annat för att hitta lättillgänglig och okomplicerad information om kläder. Tidigare forskning menar att sociala medier påverkar konsumentbeteendet genom att skapa ett behov för produkter man tidigare inte tänkt köpa. Vidare visar forskning att konsumenter påverkas mer av produktinformation från en tredje part så som vänner, familj eller referensgrupper. Vår undersökning grundar sig därför i sociala mediers stora inflytande på konsumenter och gapet mellan konsumenters attityd till och beteende vid hållbar klädkonsumtion. Uppsatsens syfte är därför att undersöka om sociala medier kan öka intresset för hållbara kläder hos yngre konsumenter. Vi fokuserar på yngre konsumenter eftersom de är uppväxta med datorer och internet samt är den grupp som flitigast använder sociala medier. I studien användes en kvalitativ metod där empiri samlades in genom fokusgrupper. Avsikten var att få en djupare förståelse för deltagarnas åsikter och idéer kring våra teman: hållbara kläder, konsumentbeteende, konsumentattityder och sociala medier. Tidigare forskning stämde överens med resultatet i vår studie där deltagarna beskrev att de inte hade möjlighet att konsumera hållbart eftersom de inte hade kunskapen om vad hållbara kläder faktiskt är. Där även textilstudenter som hade mer kunskap ansåg att det krävdes mer information för att de skulle kunna agera mer hållbart. Vidare visade även vår studie att sociala medier har en stor påverkan på ett konsumentbeteende. Genom att applicera vår empiri på ABC model of Attitudes kunde vi även se att sociala medier influerar konsumenters uppfattning, känsla och beteende vilket påverkar deras konsumentattityd. Alla deltagare i vår undersökning önskade mer lättillgänglig information om hållbara kläder i sociala medier eftersom det är en kanal de alla påverkas av. Ytterligare argumenterade de för att det krävs att fler personer tar sitt ansvar och delar kunskap om hållbara kläder för att skapa ett ökat intresse och tillslut ett förändrat beteende. Slutsatsen kunde därför dras att sociala medier kan vara ett verktyg för att öka intresset för hållbara kläder hos yngre konsumenter. Genom vår studie vill vi bidra till en djupare förståelse av konsumentbeteende samt konsumenternas attityder till hållbara kläder och sociala medier.

    Mekanisk återvinning av bomullsfibrer från konsumentavfall: Påverkan på polymerisationsgrad och spinnbarhet2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Cellulosans polymerisationsgrad (DP) är en viktig faktor vid utvärdering av möjligheterna till både mekanisk och kemisk återvinning av bomull. Enligt flera studier leder lägre DP till svagare fibrer. I denna rapport har DP hos bomullsfibrer från begagnade jeans undersökts före och efter mekanisk återvinning för att se om återvinningsprocessen eller graden av slitage på de ingående fibrerna har en påverkan på DP. Även möjligheten att spinna garn med de mekaniskt återvunna fibrerna utblandade med jungfruliga bomullsfibrer har undersökts för att se hur andelen återvunna fibrer och graden av slitage på dessa påverkar garnets styrka. Konsumentavfall i form av bomullsjeans, före och efter mekanisk återvinning,  har lösts i  bis(etylendiamin)kopparhydroxidlösning (Cuen). Viskositeten har mätts och cellulosans polymerisationsgrad har beräknats. Eftersom fibrerna inte löstes upp helt var cellulosakoncentrationen i lösningarna okänd. Därför kunde inga klara slutsatser dras om huruvida den mekaniska återvinningen eller graden av slitage på det ingående materialet hade någon påverkan på DP, även om den statistiska analysen visade på att båda variablerna hade en signifikant påverkan. DP hos återvunna fibrer från begagnade jeans är högre än vad som krävs för framställning av både viskos och lyocell, vilket gör att kemisk återvinning av denna form av konsumentavfall kan vara möjlig att utveckla industriellt. Jungfrulig bomull har ringspunnits tillsammans med 20 % och 50 % återvunna fibrer. Spinningen av garn med 50 % återvunna fibrer var på grund av upprepade garnbrott alltför tidskrävande för vara lämlig för storskalig produktion. Dragstyrkan hos ett ringspunnet bomullsgarn med 20 % återvunna fibrer försämrades inte jämfört med ett garn av 100 % jungfrulig bomull, utan kunde tvärtemot förbättras beroende på spinninställningar och kvaliteten på de återvunna fibrerna. Inblandning av 20 % mindre slitna fibrer gav ett starkare garn än 20 % slitna fibrer. Dock spanns endast en bobin av varje garn och därför krävs en större studie för att få ett större statistiskt underlag innan några mer generella slutsatser kan dras.

    Rhamnolipid as new bio-agent for cleaning of ultrafiltration membrane fouled by whey2018Inngår i: Engineering in Life Sciences, ISSN 1618-0240, E-ISSN 1618-2863, Vol. 18, nr 5, s. 272-280Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this work, rhamnolipid biosurfactant as an eco-friendly and biodegradable cleaning agent was produced by Pseudomonas aeruginosa bacteria and was used to evaluate the chemical cleaning efficiency of whey fouled ultrafiltration membranes. Thin layer chromatography (TLC) and Fourier transform infrared spectroscopy (FTIR) confirmed the successful synthesis of rhamnolipid. The produced rhamnolipid was compared to chemical cleaners including sodium hydroxide (NaOH), sodium dodecyl sulfate (SDS) and Tween 20. Ultrafiltration membranes used for fouling and cleaning analysis were prepared using phase inversion via immersion precipitation technique. For studying the fouling mechanisms, Hermia's model adapted to cross-flow was used. From the fouling mechanism experiments, it was found that the complete blocking and cake formation were the dominant fouling mechanisms. The highest values of cleaning efficiency were achieved using rhamnolipid and NaOH as cleaning agents with the flux recovery of 100%, but with considering the low concentration of the rhamnolipid used in the cleaning solution compared to NaOH (0.3 versus 4 g/L for NaOH), its application is preferred.

    Eco-designed functionalization of polyester fabric2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    There is an increased awareness of the textile dyeing and finishing sector’s high impact on the environment due to high water consumption, polluted wastewater, and inefficient use of energy. To reduce environmental impacts, researchers propose the use of dyes from natural sources. The purpose of using these is to impart new attributes to textiles without compromising on environmental sustainability. The attributes given to the textile can be color and/or other characteristics. A drawback however, is that the use of bio-sourced dyes is not free from environmental concerns. Thus, it becomes paramount to assess the environmental impacts from using them and improve the environmental profile, but studies on this topic are generally absent.

    The research presented in this thesis has included environmental impact assessment, using the life cycle assessment (LCA) tool, in the design process of a multifunctional polyester (PET) fabric using natural anthraquinones. By doing so an eco-design approach has been applied, with the intention to pave the way towards eco-sustainable bio-functionalization of textiles.

    The anthraquinones were obtained from the root extracts of the madder plant (Rubia tinctorum L.), referred to as madder dye. The research questions were therefore formulated related to the use of madder dye. Three research questions have been answered: (I) Can madder dye serve as a multifunctional species onto a PET woven fabric? (II) How does the environmental profile of the dyeing process of PET with madder dye look like, and how can it be improved? (III) What are the main challenges in using LCA to assess the environmental impacts of textile dyeing with plant-based dyes?

    It is concluded that there is a potential for the madder dye to serve as a multifunctional species onto PET. Based on the encouraging result, a recommendation for future work would be to focus on the durability of the functionalities presented and their improvement potential, both in exhaustion dyeing and pad-dyeing. LCA driven process optimization of the exhaustion dyeing enabled improvement in every impact category studied. However, several challenges have been identified which need to be overcome for the LCA to contribute to the sustainable use of multifunctional plant-based species in textile dyeing. The main challenges are the lack of available data at the research stage and the interdisciplinary nature of the research arena. It is envisaged that if these challenges are addressed, LCA can contribute towards sustainable bio-functionalization of textiles.

    A secured tag for implementation of traceability in textile and clothing supply chain2018Inngår i: The International Journal of Advanced Manufacturing Technology, ISSN 0268-3768, E-ISSN 1433-3015Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Textile and clothing industry is one of the oldest manufacturing industries and is a major contributor in the economic growth of developing countries. However, from past few decades, it has been criticised for its opaque, unsecured and untraceable nature of supply chain. Addressing these challenges, the paper proposes a system approach to introduce an item-centric secured traceability concept to monitor and control manufacturing processes and supply chain activities. In order to implement such secured traceability system, the paper describes the process for manufacturing, encoding and validating an innovative two-factor secured tag based on particle randomness that is printed on the surface of textile. Being micro-sized, the particles are easy to read and validate with pattern recognition. Further, as achieved through an uncontrolled manufacturing process, the randomness is unclonable to produce counterfeit tags. Furthermore, a sequence of experimental analyses has been conducted using various simulated scenarios to verify its applicability. A secured tag can be a low-cost and durable substitute for detachable, unsecured identifiers commercially available in the market.

    Exploring secured traceability systems for implementation in textile and clothing supply chain2018Inngår i: Proceeding TIWC conference 2018, 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Information asymmetry and security are major challenges in multi-tier supply chains. Textile and clothing (T&C) supply chain is one such example significantly affected by these problems. Due to its complex and diverse nature, involved actors find it difficult to connect and secure each supply chain links. Exploiting this situation, a parallel counterfeit market is flourishing and gaining serious momentum. Due to this, T&C industries are suffering huge economic losses and job cuts. Additionally, owing to its opaque and untraceable supply chain, T&C industries have become a world of unethical practices. Secured traceability is an effective tool that has potentials to address these issues and make the T&C supply chain transparent and secured. It is a useful mechanism to track and trace products’ history, know about the manufacturing conditions and at the same time secure it from counterfeits and attacks targeting intellectual properties. In this context, the study conduct survey of supply chain experts to explore and rank the key technological requirements (based on the specific nature of the textile product) and traceability information that can be recorded and secured by a secured traceability system. Further, based on the findings of the survey a review of the literature was conducted to explore state of the art technologies to propose a primary secured traceability structure for the T&C supply chain.

    Towards a secured traceability system for closed-loop textile supply chains2017Inngår i: Data Driven Supply Chains / [ed] K. S. Pawar; A. Potter and A. Lisec, Nottingham: Centre for Concurrent Enterprise, Nottingham University Business School, 2017, s. 359-367Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Textile and clothing (T&C) industry is characterised by complex and extensive supply chain involving various stakeholders dealing with diverse raw materials. Owing to these complexities, the textile supply chain is facing numerous challenges like, counterfeit products, limited information sharing, ineffective recycling/reuse of textile products, unethical practices and interrupted information flow. As a result, a secured traceability system that can integrate the whole value chain, record, store, and track / trace all supply chain activities, make it more transparent and at the same time safeguard it from unauthorized access, has become a prime requirement for the T&C industry. In this context, the current study conducts a literature review to identify the generic requirements of traceability and in context of T&C closed-loop supply chain (CLSC). It further evaluates the role and key requisites of a cryptographic tag for textiles product, as an additional measures/parameter to secure the traceability system and prevent unauthorised access. Finally, the paper draws on key characteristics of such cryptographic tag for textile CLSC and lay down the tentative methodology that would be followed in the future research for development of a complete secure traceability system. It is anticipated that such secured traceability system can prevent counterfeits, data leakage, bring transparency and automate the reverse logistic process.

    Konsumenternas köpbeteende inom fast fashion: En undersökning om gapet mellan attityd och beteende inom hållbarhet2018Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    De miljövänliga problem som världen står inför idag är tätt sammanhängande med den masskonsumtion som skapats av fast fashion-industrin. Detta har skapat en större efterfrågan av miljövänligt producerade kläder av konsumenter då de har en allt större inblick och påverkan på modeindustrin. Tidigare forskning visar att det är många konsumenter som tycker att det är viktigt att konsumera miljömedvetet, men utav dessa respondenter så var det dock bara cirka 30% av dessa deltagare som faktiskt agerade enligt sina miljömedvetna värderingar. Gapet mellan miljövänlig attityd och faktiska beteende kallas det gröna gapet och är något som har undersökts sedan 70-talet. Intentionen med denna uppsats är att undersöka det gröna gap som finns hos kvinnliga studenter på Textilhögskolan i Borås då dessa anses ha stor inblick i modeindustrin och dess miljömässiga påverkan men trots detta ändå handla fastfashion. Fokusgrupper sattes samman för att genom en gruppdiskussion undersöka och svara på frågan vad som påverkar konsumenter till att handla enligt sina hållbara attityder. Resultaten från undersökningen visade att lågt pris, trendig design och lättillgänglighet var de främsta faktorerna som ledde till att konsumenter handlar fast fashion hellre än hållbart mode. Resultatet visar däremot att mer och bättre information var det som skulle kunna få respondenterna att handla mer miljömedvetet. Fastän de redan är insatta i ämnet så nämndes det att det finns en otydlighet och osäkerhet gällande på vilket sätt företag faktiskt är hållbara och vad man betalar ett dyrare pris för.

    Effekter av en integrerad artikelstandardisering ochinförande av variantmoduler2015Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    I denna kandidatuppsats undersöks hur ett förändrat produktionsupplägg påverkar ett svensktproducerande företags konkurrenskraft när konkurrensen från globala lågprisalternativ medkort leveranstid ökar. Genom att byta produktionsupplägg från produktion mot lager tillmontering mot order och genom att standardisera artiklar och till viss del modulindelaprodukter kan kundorderpunkten flyttas bak i produktionsprocessen. Komponenternamonteras då ihop till slutprodukt först när kundordern anlänt, vilket bidrar till att antaletlagerförda variantartiklar minskar vilket är något som bidrar till en lägre kapitalbindning.Kostnadsbesparingen detta medför kan användas till att utveckla ordervinnande egenskaper.Exempel på sådana egenskaper är att förbättra kvaliteten på produkterna, öka mervärdet,förlänga garantin samt stärka varumärket som ett mer miljövänligt alternativ.

    Tids- och kostnadseffektivitet vid intermodala transporter2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    This study aims to explore effectiveness within intermodal transportation of semi-trailers based on the variables cost and time. Intermodal transport can be explained as a transportation of a carrier, from the origin to the final destination, using two or more modes of transport (Crainic & Kim, 2007 p.467). This study focuses on the two modes of transport rail and road. The rail transportation has big advantages towards other modes of transport since it has less impact on the environment, given that the energy is produced in Sweden (Trafikverket 2017) but there are more benefits to be utilized. The rail transportation is generally more profitable on distances greater than 500 km, thus it can transport high volumes of goods over long distances for a low cost. The fixed costs that´s added in the terminals and the rail transports low degree of flexibility compared to the road transport is the primary reasons why rail transportation isn´t profitable on shorter distances. This study has made a market research to see where the final destinations for the imported semi-trailers are located in Sweden and Norway. This, to see where there are potential to develop and create new rail shuttles from Port of Gothenburg to dry ports across the Swedish and Norwegian inland for transportation of semi-trailers. Interviews have been conducted with carriers to create a more correct view of the current situation. Study results show that the greatest volumes of the transported semi-trailers ends up in the areas around Helsingborg and Stockholm, with the region around Gothenburg excluded. Dry ports positioned in this area show the best potential for development of new rail shuttles. The results from conducted interviews with carriers express that time is the most important aspect for their operation and their clients, that is also the reason why they don´t use the railway for transportation of semi-trailers. Carriers also consider the trains to be unreliable and the railway operation in Port of Gothenburg has so far not been operating well enough for them. The result show that 38 percent of the imported semi-trailers have their final destination in the area around Gothenburg and naturally it´s not possible for the railway to compete with the road transport at such a short distance. In order for the railway to compete with the road transport, rail shuttles to regions with high flows of semi-trailers must be developed to not loose in time and flexibility. Thus, the railway transportation has other opportunities than just transportation. In dry ports there are opportunities for storage of goods, which is generally cheaper than in the port and simultaneously create time gains in the final transportation, thus the goods are closer to the customer. Port of Gothenburg can compete with other ports, which are geographically closer to a certain customer, through more rail shuttles with more frequent departures and then take more market shares within Nordic transportation.

    Personlighetsanpassat ledarskap2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Vi har i vår forskningsöversikt inte hittat någon beskrivning på hur ledarskap kan anpassas tillmedarbetares olika personlighetstyper. Vårt syfte med studien var således att ta reda på hurolika typer av ledarskap kan anpassas till anställdas olika personlighetstyper för att uppnåstörsta möjlighet till utveckling av deras motivation. Vilket är en bidragande faktor till ettföretags utveckling och bör därför ligga i ledarens intresse. Med hjälp av två olikapersonlighetsklassificeringsmodeller, teorier om ledarskap och motivation samt empiri hämtatfrån ledare i arbetslivet har vi studerat vad för typ av ledarskap som fungerar för modellernasolika personlighetstyper. Med hjälp av kvalitativ forskningsstrategi har vi använt oss avtvärsnittsdesign samt en öppen och sex semistrukturerade intervjuer för att uppnå studienssyfte.Genom vår studie kan vi på ett tydligt sätt visa på att de personligheter vi utgått ifrån kräverolika typ av ledarskap, motiveras av olika faktorer och att situationen kan ha stor inverkan pånär ett visst ledarskap passar. Resultatet av vår studie har utformats till två tabeller utifrån depersonlighetsklassificeringsmodeller vi använt oss av. Tabellerna presenterar vilkenledarskapsteori som passar till vilken personlighetstyp. Studien resulterade även i ettkonstaterande att ledare bör använda sig av relationsinriktat ledarskap i grunden ochkomplettera det med uppgiftsinriktat ledarskap, för att finna de anställdas motivation och ledadem på ett framgångsrikt sätt.

    Composite façade elements with GFRP connectors: Shear properties and sustainability aspects2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Today, with the greater importance of the environmental performance of construction materials, a significant development of precast concrete sandwich elements (PCSEs) is ongoing. With the PCSEs improving and becoming more thermal and energy efficient, it is becoming more attractive for architectural design and for acquiring Leadership in Energy and Environmental Design (LEED) certification.The focus of this study was to conduct and analyze experiments related to the shear properties of fibre reinforced polymer (FRP) plate connectors in newly developed composite façade elements. The idea of using FRP plate connectors was based on research conducted by the European Commission funded FP7 project H-House, where new innovative materials are used to achieve a more thermally efficient sandwich element that would also be lightweight, energy-efficient and durable. The work was performed in cooperation with the Swedish Cement and Concrete Research Institute (CBI) in Borås, where the laboratory tests, with four different variations of FRP plate connectors, were conducted. To analyze the results, a method called double shear test was used for stabilization of the test specimens and minimize the eccentricity of the applied vertical load. The experimental results indicated that an improved shear bearing capacity was achieved, especially for one connector type, though the effect on the stiffness was depended on how well the specimens were cast. Furthermore, it turned out that the placement of the carbon fibre reinforcement (CFR) in the inner and outer panel played a major role regarding the FRP connectors’ contribution to the shear forces. A qualitative analysis of sustainability regarding the composite elements in construction was also done.In conclusion, the FRP plate connectors have been shown to be robust and stiff enough to develop composite behaviour of the precast concrete sandwich elements and being thermal resistance, e.g. a good alternative to using in thick façade elements and reducing thermal bridging.

    Transnational Strategy Shift: The Importance of Cultural Awareness: - Case Study: IKEA2015Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [en]

    Globally operating business organizations tend to use a global strategy by using a standardized strategy as a fixed format. However, this has developed to be very ineffective for the ability to compete in the different markets worldwide. The adaptation of local preferences hence, seems to be crucial but also very complex for multinational retailers. This study therefore, determines the complexity of considerations that a shift from a global to a transnational strategy includes. The decision making of which strategy is appropriate for multinational retailers to compete on a global market can be quite puzzling, as is can be seen in the bed textile segment. Therefore this research paper investigates, within a case study of IKEA’s bed textile department, if a shift from a global to a transnational strategy is of advantage for a multinational retailer like IKEA and to what extend cultural awareness has to be considered. The methods that were used for this study include a literature review in the mentioned focus area and a collection of primary data through a qualitative research design with an open questionnaire sent to the Sales Leaders of IKEA. The research has shown that market research is an important factor when it comes to cultural related differences between the countries. Also, when dealing with the concern of adaptation of the market relevant bed textile sizes to the product range, the Sales Leaders of IKEA have perceived different concerns. Therewith a full adaptation may not be the solution for all businesses, since this depends on the product and market preferences. The cultural preferences in each country and the right degree of standardization and local preferences are a big issue for the global bed textile industry and are hence perceived as the main challenges in this concern. Possible paths for future investigations are shown by the results of this study. Thus, an inclusion of other cases could enable the possibility of a generalization of the study’s findings. Also, the same case study could be expanded by including customers input in the individual markets; this would lead to a better understanding of the customer’s preferences and a higher validity of the study. Last but not least this study has shown that there is no simple answer given whether a shift from a global towards a transnational strategy is of advantage for multinational retailers; however interesting factors concerning the shift could be identified.

    Research on ecosystems as ways of organizing innovation and firm-level growth position a focal firm at the center of each ecosystem they study. This study of the video games industry in Finland argues that it can also be human users that are are at that center. In the birth and early developmental stages of the ecosystem or a game-design project, individual human beings can absorb and live with ambiguity and absence or fluidity of rules of the game, even be entertained by and enjoy such ambiguity.

    Leveraging academic resistance to consumerism to strengthen the capitalist project: The case of Aalto University2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    •New public management, an emphasis on control, as well as consumerism, have grown their influence in universities. Taken too far, this kind of an influence can have destructive psychological and social outcomes on practices and institutions of good research, on academic collegiality, and on the peer review system. Yet, paradoxically, it appears fewer and fewer academics rise to the barricades to resist such developments. This paper analysis why and how do academics in favor of consumerism appear to win over academics in favor of collegiality?

    The art of organizing: Computer games as an art form, a business, and a community2016Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The starting points of this paper are twofold. Firstly, computer game design can be taken as an art form (Crawford 1982). Seconly, and building on the first point, computer games can be taken as a model of organising whereby there are multiple dimensions or levels of analysis (Burger-Helmchen & Cohendet 2011). In and across the starting points, this paper unfolds a set of findings and generates a set propositions. The propositions include that new forms of art such as computer games have been and will be much like old forms of art. More specifically, the proposition here is that each new particular form of art, as well as art generally, needs to be invented in order to exist (Shiner 2001). In order to persist and not only to exist for a short instance, one or another kind of a process organizing needs to happen. Such a process can unfold following a a grand design. The process of organizing can be dictated by chance or be a result of drift. Or, the process can emerge in a series of small steps. In the latter instance, hybridization or a combination, even recombination, can be the way of the happening.

    Transvaluation of the meaning of “fast” in fast food, fast music, and fast fashion2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper explores how to transvaluate, to re-evaluate and to repudiate neoliberal standards for creative and cultural industries. The paper's focus is on three creative and cultural industries -- food, music and fashion -- all of which have crafts-based origins. These industries were long under the protective eye and of, in one way or another, of the cultural system of what is a nation. However since the 1970s or the 1980s these industries have increasingly been dominated and domesticated by the still continuing rise of the values of neoliberalism, subjected to wave upon wave of reengineering and reorganization, assimilated into the global market system.

    At one extreme, affluent consumers, often affluent owner-capitalists or financiers, are empowered to determine what is good food, good music, or good fashion. These affluents are now increasingly co-creators of what they consider culturally meaningful for themselves. Growing amounts of resources flow in the direction of making and keeping the affluents content, which is not always in fit with culturally meaningful content from the perspective of the traditional or authentic creatives in these industries: the chefs, the artists, the designers, What the affluents desire are fancy restaurants, selective clubs, and expensive clothes. Catering to the lifestyles of these rich and famous is increasingly a trans-industry of its own, with ever less room for authentic cultural creation, as authenticity used to be understood. New bureaucratic forms of education and training drive by various forms of "positive psychology" reproduce the focus on the tongues, minds and navels of the affluent, as if their satisfaction and inspiration of these were the only global standard that matters.  By virtue of their new role as co-creators, the affluents are offered what is rich in meaning and high in value to them.

    At the other extreme, the authentic cultural creatives following vocation and the average citizen have received the stick, at best left holding its short end. Cultural creatives trying to follow their original call and the average citizen are now both squeezed out of being key beneficiaries of participation in these industries. What is forced down throats, into ears and on bodies are degenerated, industrialized and highly wasteful variations - fast food, fast music, fast fashion - co-created with and for the affluents. Almost explicitly hindered by market prices to access such meaning, in any case, the cultural creatives and the average citizen are face to face with the neoliberal tide that is drowning the original authenticity of arts of crafts and their meanings. Values that originally drove food, music, and fashion industries, such as sustainability, are now increasingly dominated, converted and domesticated by neoliberal, technocratic and bureaucratic values and ideologies.

    Analysis of food, music and fashion industries in various countries in this paper suggests that to transvaluate the neoliberal tide what is needed is a trans-disciplinary mindset, reminiscent of authentic innocence of the crafts-minded and pre-industrial hierarchy of life-affirming values and norms: to reflect upon, to act upon, and to adhere what is good by virtue of good with local environments and authentic ways of consumption, cultural practice, and creativity.  Recipes, hits and fashions to repudiate what has been wasteful and inefficient in fast food, music and fashion include good food, good music, upcycled clothes, and new technologies. The paper calls for further research on how to trans-valuate, trans-discipline and cross-pollinate across these recipes, hits, and fashions.

    Summit fever2016Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Mountain climbers call it “summit fever” when one or more individuals in a group of climbers become so enamored with the notion of reaching the summit of a mountain that they ignore less exciting issues such as how to safely descend the mountainside and live to tell one’s self and others about the experience. In this paper, we review decision-making literature on symmetric vs. asymmetric goal formation, as well as innocuous and fallacious learning. We develop a process theory of summit fever by defining that summit fever is when fallacious learning in chase of an asymmetric goal disproportionately narrows attention to a peak milestone. A halfway milestone that represents a peak experience then is prone to lead to goal conflation so that the way forward is compromised at the expense of reaching the ultimate goal. We illustrate the emerging framework by revisiting how and how summit fever led to a mountaineering accident on K2 in 2008 whereby 11 out of 26 climbers involved died. Our conclusions include implications for further research.

    Progress in the treatment and outcome of pediatric inflammatory bowel disease patients2016Inngår i: Expert Review of Clinical Immunology, ISSN 1744-8409, s. 1-33Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    This review discusses how treatment of pediatric inflammatory bowel disease (IBD) patients has improved with attention to therapeutic quality and cost. The number of such patients in Western countries has increased rapidly. Similarly to what has been the trend in the management of adult IBD, the pediatric IBD therapy has become more active than earlier. High use of immunosuppressants has helped to control the extensive and aggressive course of pediatric IBD. Full disease control already at an early phase has advantages such as to preserve normal child growth and development, to maintain overall good health and quality of life, as well as to decrease the psychosocial burden of the disease. A key research direction is to develop the more active approach into a way to reduce healthcare costs by decreasing the so-far high rate of surgery of pediatric IBD patients.

    Designers as innovators in organizational contexts: A proposal for a typology2016Rapport (Annet vitenskapelig)
    Abstract [en]

    Task 2.2.2: Developing a Typology of the Roles of Designer and Design Competence in Innovation

    The purpose of this paper is to specify and develop a classifica­tion scheme of the roles of designers­­ in innovation, in particular to how they may contribute to business and economic growth and success. The purpose, in other words, is to make sense of such new concepts in the new and conflated field of innovation and design as “open innovation” and “co-designing” and of how to become an innovative and creative organization that is highly successful; whether talking about in-house designers, hiring design consultancies to work on product or service design or on organizational processes in commercial or public contexts

    Despite a high interest, there has been a paucity of research that would have defined or specified on the basis of case-based evidence, for example, roles that designers and their competence can have as a force for innovation. Such definition is the objective of our research project, Creativity for Growth and Innovation in Europe (Cre8tv.EU), where we define these roles and create a typology for the roles designers and design competence have for innovation and how such design involvement can be harnessed for creating competitive advantage of firms.

    Fermentative hydrogen and methane productions using membrane bioreactors2015Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The role of energy as a stimulant for economic growth and environmental sustainabilityof any nation has made the focus on green fuels, including fermentative hydrogen (bioH2) andmethane (bioCH4), to be a priority for the World’s policy makers. Nigeria, as the most populousAfrican country, with worsening energy crisis, can benefit from the introduction of the bioH2 andbioCH4 technologies into the country’s energy mix, since such technologies have the potential ofgenerating energy from organic wastes such as fruit waste.Fruit waste was studied in detail in this work because of its great economic andenvironmental potential, as large quantities of the wastes (10–65% of raw fruit) are generatedfrom fruit consumption and processing. Meanwhile, bioH2 and bioCH4 productions involvinganaerobic microorganisms in direct contact with organic wastes have been observed to result insubstrate and product inhibitions, which reduce the gas yields and limit the application of thetechnologies on an industrial scale. For example, in this study, the first experimental work todetermine the effects of hydraulic retention times and fruit mixing on bioH2 production fromsingle and mixed fruits revealed the highest cumulative bioH2 yield to be equivalent to 30% ofthe theoretical yield. However, combining the fermentation process with the application ofmembrane encapsulated cells and membrane separation techniques, respectively, could reducesubstrate and product inhibitions of the microorganisms. This study, therefore, focused on theapplication of membrane techniques to enhance the yields of bioH2 and bioCH4 productions fromthe organic wastes.The second experimental work which focused on reduction of substrate inhibition,involved the investigation of the effects of the PVDF membrane encapsulation techniques on thebioH2 and bioCH4 productions from nutrient media with limonene, myrcene, octanol and hexanalas fruit flavours. The results showed that membrane encapsulated cells produced bioCH4 fasterand lasted longer, compared to free cells in limonene. Also, about 60% membrane protectiveeffect against myrcene, octanol and hexanal inhibitions was obtained. Regarding bioH2production, membrane encapsulated cells, compared to free cells, produced higher average dailyyields of 94, 30 and 77% with hexanal, myrcene and octanol as flavours, respectively. The finalpart of the study, which was aimed at reducing product inhibition, involved the study of theeffects of membrane permeation of volatile fatty acids (VFAs) on the bioreactor hydrodynamicsin relation to bioH2 production. The investigation revealed that low transmembrane pressure of104Pa was required to achieve a 3L h-1m-2 critical flux with reversible fouling mainly due to cakelayer formation, and bioH2 production was also observed to restart after VFAs removal.The results from this study suggest that membrane-based techniques could improve bioH2and bioCH4 productions from fermentation media with substrate and product inhibitions.

    Evaluation of Fermentative Hydrogen Production from Single and Mixed Fruit Wastes2015Inngår i: Energies, ISSN 1996-1073, E-ISSN 1996-1073, Vol. 8, nr 5, s. 4253-4272Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The economic viability of employing dark fermentative hydrogen from wholefruit wastes as a green alternative to fossil fuels is limited by low hydrogen yield due to theinhibitory effect of some metabolites in the fermentation medium. In exploring means ofincreasing hydrogen production from fruit wastes, including orange, apple, banana, grapeand melon, the present study assessed the hydrogen production potential of singly-fermentedfruits as compared to the fermentation of mixed fruits. The fruit feedstock was subjected tovarying hydraulic retention times (HRTs) in a continuous fermentation process at 55 °C for47 days. The weight distributions of the first, second and third fruit mixtures were 70%,50% and 20% orange share, respectively, while the residual weight was shared equally bythe other fruits. The results indicated that there was an improvement in cumulativehydrogen yield from all of the feedstock when the HRT was five days. Based on the resultsobtained, apple as a single fruit and a fruit mixture with 20% orange share have the mostimproved cumulative hydrogen yields of 504 (29.5% of theoretical yield) and 513 mL/gvolatile solid (VS) (30% of theoretical yield ), respectively, when compared to other fruits.

    Enhanced Fermentative Hydrogen and Methane Production from an Inhibitory Fruit-Flavored Medium with Membrane-Encapsulated Cells.2015Inngår i: Membranes, ISSN 2077-0375, E-ISSN 2077-0375, Vol. 5, nr 4Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study focused on the possibility of improving fermentative hydrogen and methane production from an inhibitory fruit-flavored medium using polyvinylidene fluoride (PVDF) membrane-encapsulated cells. Hexanal, myrcene, and octanol, which are naturally produced in fruits such as apple, grape, mango, orange, strawberry, and plum, were investigated. Batch and semi-continuous fermentation processes at 55 °C were carried out. Presence of 5 g/L of myrcene, octanol, and hexanal resulted in no methane formation by fermenting bacteria, while encapsulated cells in the membranes resulted in successful fermentation with 182, 111, and 150 mL/g COD of methane, respectively. The flavor inhibitions were not serious on hydrogen-producing bacteria. With free cells in the presence of 5 g/L (final concentration) of hexanal-, myrcene-, and octanol-flavored media, average daily yields of 68, 133, and 88 mL/g COD of hydrogen, respectively, were obtained. However, cell encapsulation further improved these hydrogen yields to 189, 179, and 198 mL/g COD. The results from this study indicate that the yields of fermentative hydrogen and methane productions from an inhibitory medium could be improved using encapsulated cells.

    En jämförande studie mellan platsgjuten betongvägg och skalvägg: Kostnad och tid för respektive byggmetod2015Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Examensarbetet utgör en jämförelse mellan två byggmetoder: platsgjutna betongväggar och skalväggar. Studien har gjorts för SEFA Betongentreprenad AB med avsikt att redogöra den mest lönsamma byggmetoden.De centrala aspekter som belyses i detta examensarbete är kostnader, tider och arbetsmiljö.Resultatet visar att byggnation med skalväggar leder till ökade materialkostnader i projektet, vilket också leder till en högre självkostnad för betongentreprenören. Byggtiden blir däremot kortare och det gynnar totalentreprenören vars arbetsplatsomkostnader och arbetsledningskostnader. Utöver detta ger skalväggar en bättre arbetsmiljö i jämförelse med platsgjutna väggar eftersom mindre arbetsmoment krävs på arbetsplatsen vilket också leder till minskning av antalet olyckor.Tider och kostnader baseras på enhetstider från Nybyggnadslistan 1999 samt prisförfrågningar. Därefter har vi gjort en noggrann kalkylering med hjälp av olika datorprogram så som Bluebem, Wikells och Excel för att kunna sammanställa den totala byggtiden och självkostnaden. Undersökningen baseras på dokumentation för ett byggprojekt som omfattar både en skola och studentbostäder i Lund.

    Belöningssystem som styrmedel för kvalitetsmål: En studie om den svenska telekombranschen2015Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Telekombranschen står inför flera utmaningar, fokuset för den här studien handlar om utmaningen med kvalitetsmål. För den här studien blev det naturligt att undersöka problematiken genom att studera de anställda inom branschen. Den här studien utforskar vad som motiverar de anställda att arbeta kvalitativt med de tjänster som erbjuds kunderna, studien fokuserar på fem olika ledare i fem olika organisationer och anställda med olika säljandebefattningar. Studien undersöker belöningssystem och hur dessa är tänkta att motivera medarbetare att nå sina målbilder men även om organisationerna tenderar att lyfta fram vissa mål framför andra. I studien används både semistrukturerade intervjuer samt ett kvantitativt enkätutskick för att samla in data. Studien baseras på etablerade teorier inom marknadsföring, management samt psykologi. Det empiriska datamaterialet analyserades med stöd från teorierna vilket gav slutsatsen att belöningssystemen i branschen tyder på att vara missriktade i den utsträckning att det kan ha en påverkan på medarbetarnas motivation och deras driv för att arbeta för en hög kvalitet.

    Visualisering för ökad delaktighet2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    I en global värld som ständigt utvecklas och konkurrensen hårdnar har ständiga förbättringar bliviten del av vardagen för de flesta företag. Ofta visualiseras förbättringar på en tavla. Tavlan är ett brahjälpmedel för att ledare på ett enkelt men effektivt sätt ska visualisera mål för dess medarbetare.Medarbetarna ska med detta hjälpmedel känna sig mer delaktiga genom att de får vara med ibeslutsprocessen. Utöver de hjälpmedel som existerar måste också ett coachande ledarskapföreligga bland ledare, där högkvalitativ kommunikation och konstruktiv feedback är något som ärdel av det vardagliga arbetet. Det gäller att skapa en tvåvägskommunikation som består av attlyssna, tala, komma överens och därefter agera mellan parterna. Feedbacken ska varaindividanpassad såväl som gruppanpassad för att få ut bästa tänkbara resultat.

    Den Moraliska Kompassen – En guide till marknadsföring av välgörenhet2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Bakgrund: Tidigare studier visar en ökad misstro till välgörenhetsorganisationer samtidigt som det ökade antalet organisationer ökar konkurrensen mellan organisationerna om bidragsgivarnas donationer. Detta ställer krav på välgörenhetsorganisationer att marknadsföra sig för att nå ut till allmänheten. Eftersom organisationerna till stor del är beroende av allmänhetens förtroende för att finansiera sin verksamhet är den ökade misstron oroväckande. Vi ställer oss därför frågan: Kan det nya intresset för marknadsföring inom branschen användas för att vinna tillbaka allmänhetens förtroende och därmed minska risken för uteblivna donationer?Syfte: Syftet med studien var att studera vilka faktorer som påverkar allmänhetens förtroende för välgörenhetsorganisationer. Detta ska sedan ligga till grund för en analys av hur marknadsföringsinsatser för välgörenhetsorganisationer kan bidra till ett ökat förtroende hos allmänheten.Metod: En kvalitativ insamlingsmetod användes där 21 respondenter deltog i fyra olika fokusgrupper. Respondenterna delades upp efter nivå av engagemang inom välgörenhet som på så sätt skulle kunna representera olika målgrupper. Empirin har sedan analyserats med hjälp av innehållsanalys.Resultat: De mest framträdande faktorerna som påverkade respondenternas förtroende var transparens, tydlighet i vad varje bidrag får för positiva konsekvenser, handlingar hos representerande för organisationen och personliga rekommendationer. Utöver detta så var det även viktigt att marknadsföringen var effektiv men inte framstod som alltför kostsam. Vidare visade sig en del skillnader mellan respondenter med högt och lågt engagemang avseende hur viktiga de olika faktorerna var för respektive målgrupp, vilket skulle kunna påverka hur organisationerna väljer att utforma sin marknadsföring.Slutsats: Välgörenhetsorganisationer kan påverka allmänhetens förtroende genom att anpassa sin marknadsföring för att visa transparens och tydlighet i vad varje bidrag ger för positiva konsekvenser. Marknadsföring i form av representanter för organisationer och word-of-mouth hade även stor påverkan, framförallt på de som är mindre engagerade inom välgörenhet. Utformning och medieval kan med fördel anpassas utefter målgrupp, beroende på mottagarens befintliga engagemang inom välgörenhet.

    Cultural Differences in Fashion Magazines: Targeting Vogue2017Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The purpose of this study is to examine how different cultures within clothing and fashion are featured in the magazine Vogues fashion reportages. The aim is to enlighten editors with infashion media of these cultural differences in order to increase diversity. To pursue the purpose of the study a qualitative approach was chosen where photographs were used as the data that later on was studied through an image analysis. The study looks at six different editions of the fashion magazine Vogue, which indicates a chosen research design as multiple case studies. The six Vogue editions are: US, Japan, Paris, Arabia, India and Brazil, in which clothes, color and context have been analyzed in each editions reportages. The editions Vogue US, Vogue Japan, Vogue Paris, Vogue Arabia, Vogue India and Vogue Brazil reportages wa sanalyzed and compared, and distinct cultural differences was seen in terms of color, cultural clothing and fashion contexts. While Vogue US, Vogue Japan and Vogue Brazil had a widerange in diversity regarding models with different appearance, which were light-skinned anddark-skinned, Vogue Arabia, Vogue India and Vogue Paris had not. Vogue Arabia, Vogue India, Vogue US and Vogue Japan were however diverse in the cultural clothing, where clothes that was shown in the reportages was a mix of different cultural clothes. The researchers therefore found Vogue US and Vogue Japan the most diverse.

    The Next Wave of the Suit-Era: A Forecasting Model of the Men’s Suit2017Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Background   By the beginning of the 20th century, the men’s suit entered the menswear market as one the most important fashion garments everdevised. At the same time, fashion became mainly a female engagement, resulting in an under representation of men’s fashion through out the past decade. Relating to the textile and apparel industry, fashion forecasting has become an increasingly important business activity. But the nature of fashion forecasting and the historical neglecting of the men’s suit has created complications when performing this activity.

    Purpose   The purpose of this thesis is to examine the men’s suit and its development from the given starting point in the 20th century until today, in order to derive a fashion forecasting model suggesting its development by 2029.

    Design/methodology/approach   This thesis uses an abductive research approach and qualitative multi-methods to answer the research questions. The usage of an intermediate research project answers the first research question. The second research question is answered through the synthesis ofa literature study and semi-structured interviews. The third research question is answered through the derived forecasting model, accomplished through theory matching.

    Findings   By carrying out a historical investigation of the men’s suit, and then applying this to the derived forecasting model, the men’s suit is expected to be found in both single- and double-breast styles. The suit will have classical features represented through the length, canvas structure, and shoulder construction.

    Originality/value   This paper carries out a historical investigation of the men’s suit never been done before. It introduces an evaluation framework to categorise and classify the men’s suit, as well as a forecasting model followed by an actual fashion forecast.

    Measuring sustainability: Balanced scorecard approach to Higg Index2015Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Purpose The purpose of this thesis is to investigate the challenges related to measuring sustainability within the textile industry. The study concentrates on the industry-specific self-assessment tool Higg Index and strives to point out the challenges of using the tool. In order to find a solution for the measurement problems, the purpose is to investigate how the current, non-financial Higg Index indicators could be translated into financial ones. Method The nature of the research is qualitative and it comprises of two parts: structured interviews and a desk research. Methodological triangulation is used in order to gain data on different levels – both from the users of the Higg Index and from literature. The data collection has been conducted through four structured interviews with the users of the Higg Index. The second part of the thesis is concerned with converting the non-financial indicators of the Higg Index into financial indicators using the balanced scorecard approach. Conclusion Measuring sustainability has been considered difficult due to the qualitative nature of the measured matters. Higg Index has proven to be a comprehensive self-assessment tool for organizations in the textile industry to use. It is considered to enhance communication, increase information sharing, and facilitate benchmarking. However, in order to develop the tool and make it more attractive to non-users, there are opportunities for improvement. These opportunities include adding verification and making the data collection easier. Transforming non-financial indicators of the Higg Index into financial indicators can simplify the data collection and increase the attractiveness of sustainability performance measurement tools.
