New ASTM Standard tests and supports biodegradability of plastics in water

摘要

LABORATORIES will soon be able to use a new ASTM International standard to test and better understand biodegradability of plastics in marine environments. The new standard (soon to be published as D7991, Test Method for Determining Aerobic Biodegradation of Plastics Buried in Sandy Marine Sediment Under Controlled Laboratory Conditions) provides ways to simulate how plastics degrade in seawater-soaked sand.
