Summary

Researchers investigated what happens to biodegradable plastics like compostable bags and food containers when they enter composting and anaerobic digestion systems with food waste, finding that these plastics may not fully break down and can leave behind plastic fragments that pose environmental risks.

The issue of (micro) plastic pollution has received much attention. The fate of discarded biodegradable plastic products (plastic bags, lunch boxes, etc.) entering the engineering environment (aerobic composting and anaerobic digestion) with food waste, as well as...
