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 a greater environmental threat than conventional polyester fibers, particularly to earthworms, which are vital for soil health. The research found higher mortality rates in earthworms exposed to bio-based fibers, raising concerns about their ecological impact. This highlights the need for thorough testing of new materials before they are widely adopted as alternatives to plastics, as part of efforts to address microplastic pollution.
