Economic viability requires higher recycling rates for imported plastic waste than expected

open access: yesNature Communications
The environmental impact of traded plastic waste hinges on how it is treated. Existing studies often use domestic or scenario-based recycling rates for imported plastic waste, which is problematic due to differences in recyclability and the fact that ...
