General Soil Biodegradation Testing
What is General Soil Biodegradation Testing?
This test measures the final aerobic biodegradability of plastics and other materials under soil conditions. Using a closed respirometer system, it tracks oxygen consumption or carbon dioxide generation. The results help minimize environmental impacts and support the development of renewable materials.
