General Soil Biodegradation Testing
What is General Soil Biodegradation Testing?
General soil biodegradation testing is a method for measuring the ultimate aerobic biodegradation of plastics and other materials under soil conditions. This test employs a closed respirometer system to monitor either oxygen consumption or carbon dioxide evolution. The results are used to minimize environmental impacts and support the development of renewable materials.
