Bio-Based Fibers May Pose Greater Environmental Risks Than Plastics

A new study reveals that bio-based materials, often seen as eco-friendly, could harm key species more than conventional plastics.

Research conducted by the University of Plymouth and the University of Bath highlights the potential ecological risks of bio-based fibers like viscose and lyocell.
In high concentrations, these fibers resulted in higher mortality rates among earthworms compared to polyester, with up to 80% dying from viscose exposure.
Even at environmentally relevant concentrations, bio-based fibers negatively impacted earthworm reproduction and growth, raising concerns about their ecological impact.
The study emphasizes the need for thorough environmental testing of new materials before they are widely adopted as alternatives to conventional plastics.
These findings come as global leaders prepare for discussions on a potential Global Plastics Treaty, underscoring the importance of independent scientific evidence in decision-making.
