Does polyester fabric emit microplastics during weathering in outdoor tree boxes?

Polyester fabric, a common synthetic material, has raised concerns about its environmental impact, particularly regarding microplastic pollution. When exposed to outdoor conditions, such as in tree boxes, polyester can undergo weathering due to sunlight, rain, and mechanical stress. Studies suggest that this weathering process may cause the fabric to shed microplastics—tiny plastic particles that can persist in the environment and harm ecosystems. While research on polyester in tree boxes is limited, evidence from similar outdoor applications indicates that microplastic release is likely. To mitigate this issue, alternatives like natural fibers or treated synthetic fabrics could be explored. Further studies are needed to quantify the extent of microplastic emissions from polyester in tree boxes and their ecological effects.
