AEROBIC BIODEGRADABILITY

ULTIMATE - AEROBIC BIODEGRADABILITY OF POLYMERS BY ANALYSIS OF EVOLVED CARBON DIOXIDE - ISO 14855-1 / IS 14855-1

Model Code : SEWAB01

This method determines ultimate aerobic biodegradability of organic polymer under controlled compositing conditions by measurement of the amount of carbon dioxide evolved and the degree of disintegration of the plastic at the end of test. This method is designed to stimulate typical aerobic composting conditions for the organic fraction of solid mixed municipal waste. The test material is exposed to an inoculum which is derived from compost.
