A Trace Additive Helped PLA Break Down in Gentler Compost
University of Minnesota researchers report a material strategy intended to make compostable PLA degrade under backyard-bin conditions.
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.
Why it matters
University of Minnesota researchers report a material strategy intended to make compostable PLA degrade under backyard-bin conditions.
