Study: Eco-Fibers Could Be More Harmful Than Plastics

A study published in Environmental Science and Technology reveals that bio-based fibers like viscose and lyocell, intended as eco-friendly alternatives to plastics, may pose greater risks to earthworms than conventional polyester fibers. The research found higher mortality rates and adverse effects on earthworm reproduction and growth when exposed to these bio-based fibers. The findings highlight the need for thorough testing of new materials before they are widely adopted as plastic substitutes, emphasizing the complexity of addressing microplastic pollution.
