Every percentage point of recovery matters when you’re processing thousands of tons per year. If you purchase 1,000 tons of baled plastic and only sell 700 tons of finished product, the missing 300 tons represents material you paid for\u2014plus the labor, energy, water, and disposal costs that went into processing it. Improving material recovery often delivers faster returns than chasing incremental throughput gains.<\/p>\n
This guide explains what high recovery rates mean in real production environments, identifies where yield is commonly lost, and outlines the equipment choices and process controls that consistently push recovery above 95% on suitable feedstock.<\/p>\n
Two common mistakes inflate recovery numbers: counting water as product weight, and blaming the processing line for contaminants that were never recoverable polymer to begin with.<\/p>\n
