Utsortering av matavfall från hushåll i Vindelns kommun : Statistisk analys av avfallsdata samt studie av kunskap kring metoder för ökad sorteringsgrad

Sammanfattning: One third of the food produced for human consumption ends up as food waste. Sweden has enacted laws and regulations concerning municipalities waste management as a result of EU directives. By 2021 all municipalities are obliged to have a system for collection of food waste. Vindeln established sorting of food waste on March 1, 2020 for households and organisations. The purpose of this study was to investigate whether there was a significant difference between the amount of food waste that was generated in Vindeln households and the amount of food waste that was recycled. The investigations were performed using household waste composition analyses and weight data from recycled food waste. A comparison between Vindeln and the national average was performed to create a wider image of the waste situation. The results showed that there was a significant difference between the amount of food waste being generated in Vindeln and the average Swedish food waste. There was however not a significant difference between the amount of food waste generated in Vindeln and the food waste that was sorted out. A literature study of the state of knowledge on methods to improve household sorting was also performed. The methods to improve household recycling that are already in use is mainly consistent with the methods that scientific research studies show, such as communication, information and economic instruments. There are additional methods that can improve the recycling even more, for instance continuous feedback and improved physical circumstances.
