Across the ASR processing industry, one issue continues to impact operators more than almost any other: glass and rock contamination in ASR fines. These heavy materials not only reduce recovery efficiency but also cause significant wear and tear on downstream equipment when they’re not removed early in the process.

Many facilities struggle to separate these contaminants effectively, and the problem often becomes more severe as throughput increases or material streams change. The result is higher maintenance costs, shorter component life, and reduced overall system reliability.

At Engineered Recycling Systems, we work with ASR fines processing every day, and we understand the challenges operators face when dealing with glass, rocks, and other heavy contaminants. Our ASR Fines Processing System is engineered to remove these materials as a first step, minimizing abrasion and mechanical stress throughout the rest of the process.

By addressing contamination early, facilities achieve cleaner fines, smoother operation, and longer equipment life — all while improving recovery efficiency.

If your facility is experiencing issues with glass or rock contamination in your fines stream, our team is ready to help. We can review your application, discuss your material flow, and determine the best approach for improving your fines processing performance.
