ISO 16929 – Pilot Scale Composting Test
ISO 16929 is a standard composting method that determines the degree of disintegration of materials in a pilot-scale test under defined composting conditions.
The ISO 16929 typically runs for 12 weeks and is often requested for consumer and agricultural products including plastics, tarps, and textiles.
The pilot scale composting provided by ISO 16929 is an important part of the ASTM D6400 compostability testing. In addition to disintegration being a required component of ASTM D6400, ISO 16929 is a key part in the assessment that represents a less idealized and more realistic composting environment.
Aerobic biodegradation and disintegration of materials under controlled composting conditions is generally the type of testing that regulatory agencies require in order to make product claims.
