What are the biodegradability challenges of polyethylene in temporary installations?

Polyethylene, a widely used plastic in temporary installations, poses significant biodegradability challenges. Its synthetic polymer structure resists natural decomposition, leading to long-term environmental persistence. In temporary setups like event stages, signage, or construction barriers, polyethylene often ends up as waste after short-term use. Microorganisms struggle to break down its carbon-carbon bonds, resulting in decades-long degradation timelines. UV exposure and mechanical stress can fragment polyethylene into microplastics, exacerbating pollution. While additives claim to enhance biodegradability, their effectiveness remains debated. Sustainable alternatives like bioplastics or reusable materials are emerging, but cost and performance barriers hinder widespread adoption. Addressing polyethylene's environmental footprint requires innovation in material science and better end-of-life management strategies.
