Anthesis AB has been assigned by the Swedish Environmental Protection Agency to conduct a socio-economic analysis of the introduction of ecodesign criteria to reduce microplastics from washing of textiles. The purpose of the socio-economic analysis carried out in this study is to start framing the problem with microplastics emissions from laundry from a socio-economic perspective. More specifically the study aims to provide a structure for analysing the performance of policy instruments concerning microplastics and to demonstrate the potential socio-economic impacts of implementing filter requirements.
