Study finds cellophane bee nest linings produce biodegradable natural plastic

Scientists investigating ground-nesting cellophane bees in eastern Tennessee found that translucent cell linings in nests are composed of a natural polyester comparable to synthetic plastic.

Laboratory analysis showed the nest lining material is flexible and foldable during active nesting periods, mimicking high-performance industrial plastics.

Researchers discovered that the nest linings undergo significant natural degradation within 11 months in ambient soil, with polyester content dropping from 73% to 40% in four months.
