A recent study by CNRS highlights that biodegradable plastic bags, commonly found in supermarkets, only partially decompose in soil, raising questions about their environmental impact. In a participatory experiment called Plastizen, researchers observed that after three months, a significant number of these bags remained intact, leading to concerns over their potential to fragment into microplastics. The findings prompt skepticism about the efficacy of biodegradable plastics and underscore the need for controlled conditions for effective degradation.
