Aquatic Biodegradation Testing

What is Aquatic Biodegradation Testing?

This test assesses the biodegradability and disintegration of plastics and other materials in river and wastewater treatment environments. It measures the decomposition capacity of materials under simulated wastewater treatment and marine conditions, helping prevent the release of pollutants into rivers and oceans, thereby contributing to environmental protection.
