Bio-based Fibers: An Unexpected Environmental Threat

A study published in Environmental Science and Technology reveals that bio-based fibers like viscose and lyocell may pose greater environmental risks than conventional polyester, particularly to earthworms, which are vital for soil health. The research found higher mortality and adverse effects on earthworm reproduction and growth when exposed to these bio-based fibers. This highlights the need for thorough environmental testing of new materials before they are widely adopted as alternatives to plastics. The study is part of the BIO-PLASTIC-RISK project, emphasizing the complexity of addressing microplastic pollution.
