D6400 (Standard Specification for Labeling of Plastics Designed to be Hot- composted in a Municipal or Industrial Facility)

D6400 is an ASTM standard that sets the guidelines for labeling plastics as suitable for industrial or municipal composting. It ensures that biodegradable plastics will break down effectively in composting facilities, leaving minimal environmental impact. The standard details testing methods, labeling requirements, and performance criteria so consumers and waste processors can identify plastics designed to decompose under commercial composting conditions. This helps promote sustainable waste management by supporting compostable plastics that genuinely break down in proper facilities, reducing landfill accumulation and environmental pollution.
