Cellophane Bees Inspire Research for Biodegradable Plastics
Researchers from Virginia Tech, the University of Tennessee, and the University of Minnesota have discovered that the plastic-like lining produced by cellophane bees breaks down in ordinary soil within months. This natural material, which resembles polyethylene, offers a potential solution to the challenge of creating durable yet biodegradable plastics. The findings, published in the Proceedings of the National Academy of Sciences, indicate that the bee's polyester lining, despite its structural similarities to human-made plastics that persist for centuries, degrades significantly faster. The team studied nests of the unequal cellophane bee (Colletes inaequalis), a common North American species, and observed that the linings remained intact for about four months, then cracked by seven months, and crumbled within approximately a year. This rapid degradation is unexpected given the material's semicrystalline nature and chemical cross-links, features typically associated with slower breakdown in synthetic pla...
