It notes a decrease in the share of glass, paper, and biodegradable waste compared to a 2007/2008 study, while highlighting that current landfilling of mixed waste would exceed legal limits for biodegradable content. Analysis of separately collected streams shows that packaging waste consists primarily of plastics (45%), and electronic waste is dominated by large household appliances.","ai_generated":true,"unit":"sei-001178#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"Biodegradable waste is the largest component of mixed municipal waste in Estonia, with an average share of 48%.
