Drinking Water Compliance Challenges

KTW-BWGL is a framework of the German Environmental Agency to evaluate plastics and other organic materials in contact with drinking water. It sets stringent requirements for all materials in contact with drinking water, directly impacting product approval and market access in Germany. Non-compliant components create regulatory risk, requalification effort, and delays.
