Aquatic Biodegradation Testing

What is Aquatic Biodegradation Testing?

Aquatic biodegradation testing evaluates the biodegradability and disintegration of plastics and other materials in river and wastewater treatment environments. It measures the biodegradation process of materials under simulated wastewater treatment and marine conditions, helping to prevent the release of pollutants into rivers and oceans and contributing to environmental protection.
