    Life cycle assessment of supermarket food waste2017In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 118, p. 39-46Article in journal (Refereed)
    Abstract [en]

    Retail is an important actor regarding waste throughout the entire food supply chain. Although it produces lower amounts of waste compared to other steps in the food value chain, such as households and agriculture, it has a significant influence on the supply chain, including both suppliers in the upstream processes and consumers in the downstream. The research presented in this contribution analyses the impacts of food waste at a supermarket in Sweden. In addition to shedding light on which waste fractions have the largest environmental impacts and what part of the waste life cycle is responsible for the majority of the impacts, the results provide information to support development of strategies and actions to reduce of the supermarket's environmental footprint. Therefore, the food waste was categorised and quantified over the period of one year, the environmental impacts of waste that were generated regularly and in large amounts were assessed, and alternative waste management practices were suggested. The research revealed the importance of not only measuring the food waste in terms of mass, but also in terms of environmental impacts and economic costs. The results show that meat and bread waste contributes the most to the environmental footprint of the supermarket. Since bread is a large fraction of the food waste for many Swedish supermarkets, this is a key item for actions aimed at reducing the environmental footprint of supermarkets. Separation of waste packaging from its food content at the source and the use of bread as animal feed were investigated as alternative waste treatment routes and the results show that both have the potential to lead to a reduction in the carbon footprint of the supermarket.

    Bread loss rates at the supplier-retailer interface – Analysis of risk factors tosupport waste prevention measures2019In: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, p. 128-136Article in journal (Refereed)
    Abstract [en]

    This paper quantifies bread waste throughout the Swedish supply chain and investigates the loss rate of prepackagedbread products at the supplier-retailer interface. The goal is to understand the extent of bread waste inSweden and to identify risk factors for high quantities of waste at the supplier-retailer interface, in order toprovide information supporting waste prevention measures. The study uses primary data, in combination withnational statistics and data from sustainability reports and the literature. Primary data were collected from 380stores of a Swedish retail company and a bakery. Bread waste was calculated to be 80 410 tons/year in Sweden,the equivalent of 8.1 kg per person/year, and was found to be concentrated at households and in retail, specificallyat the supplier-retailer interface. The results provide evidence that take-back agreements between suppliersand retailers, where the retailer only pays for sold products and the supplier bears the cost of the unsoldproducts and their collection and treatment, are risk factors for high waste generation. Current business modelsmay need to be changed to achieve a more sustainable bread supply chain with less waste.
