Summary

University of Minnesota researchers report a material strategy intended to make compostable PLA degrade under backyard-bin conditions.

The team added a small amount of a degradation-promoting component to polylactic acid so the plastic could break down more readily outside industrial composting. The material result is promising, but it does not make ordinary PLA backyard-compostable or override local disposal guidance.
