Abstract [en]

Lignocellulosic biomass is emerging as an important feedstock for biofuel production. Bioethanol is one of the most common liquid biofuels in the transportation sector. However, its production process is still inefficient due to the large quantity of production waste that is left unused after the distillation process. In this paper, the biomethane potential of bioethanol production waste is analysed. The results are compared with the biomethane potential of samples from different stages of the bioethanol production process (pretreatment, hydrolysis and fermentation), and that of untreated biomass. In this study, barley straw is used as a biomass crop and N 2 explosive decompression (NED) is applied as a pretreatment method. The results show that bioethanol production waste has higher methane yields (1.17 mol CH 4 /100 g) than raw barley straw (1.04 mol CH 4 /100 g). Production waste also has a higher degradation rate (0.252) than untreated material (0.138), and achieves 95% of the maximum methane yield much faster (7.8 days) than untreated samples (22 days). This shows that production waste can be used for further anaerobic digestion (AD) to add value to the bioethanol production chain. NED pretreatment is an effective method of pretreatment.

Abstract [en]

This data article ranks 294 countries worldwide with more potential available, of cereal based agricultural residues for bioenergy production. Nine different cereal-based agricultural waste products (barley, wheat, millet, oat, rice, and rye straw, sorghum straw/stalk, and maize cob) are used. The tables and figures are grouped by the most prevalent Köppen-Geiger climate classification (tropical/megathermal, dry (desert and semi-arid), temperate/mesothermal, continental/microthermal), continent and region. The data was collected by the authors from FAO bioenergy and food security rapid appraisal tool (excel-based tools) that uses crop yields and production with 10 years (2005–2014) average annual production to estimate the residue yield (t/ha), by feedstock.

Abstract [en]

Lignocellulosic biomass is an attractive feedstock for the production of liquid (eg. biofuel) or gaseous (eg. methane) fuels for the transportation sector. The bioethanol production process still produces a large quantity of production waste following the distillation process. Stillage consists mostly of lignin, hemicellulose, extractives, and yeast and therefore does not have any commercial value. The conversion of bioethanol production waste into gaseous biofuels like biogas or biomethane is a promising solution when it comes to transforming stillage into value-added products, enhancing the value of the biomass, and as a strategy for achieving zero-waste societies. This study aims to investigate the potential of bioethanol production waste for biomethane production. The results are compared with samples from different stages of the bioethanol production process. Milled barley straw (Hordeum vulgare) was used as a feedstock to produce energy in the form of methane, and the flue gas pre-treatment method (with and without bubbling) was applied. The results show that the methane production yield of bioethanol production waste, which has been pretreated with flue gas without bubbling is 5% higher than that of untreated substrate, and can achieve 94% of the methane production of fermented samples. Bioethanol production waste from substrates, which have been pretreated with flue gas with bubbling have a methane production level that is 29% higher than that of untreated materials. The results suggest that methane yields are influenced by the bubbling process. It is reasonable to use bioethanol production waste for the production of energy in the form of methane and to increase the energy output from the biomass.

Abstract [en]

This paper reviews second-generation biofuel production chain and focuses on its energetic, economic and environmental impacts. The biggest challenge in the production of bioethanol from lignocellulosic material refers to the biomass waste that is left over after the separation of bioethanol in the distillation process. This waste still has high energetic value and could be further utilised to add value to the production chain. Furthermore, the environmental impact of untreated waste from bioethanol production is very high, which also requires attention. Anaerobic digestion of bioethanol production waste has been proposed as a possible solution to utilise the energetic potential of this waste and lower its environmental impact.
