A Six-Component Multi-Criteria Evaluation Protocol for Incoming Post-Industrial and Post-Consumer Recycled Plastic Resin Batches in Secondary Industrial Supply Chain Operations
Abstract
The reliable integration of post-industrial and post-consumer recycled plastic resins into industrial manufacturing supply chains requires a systematic and repeatable methodology for evaluating incoming batch quality that goes beyond single-parameter physical testing. This paper presents a six-component multi-criteria evaluation protocol developed through more than twenty years of commercial practice in secondary polymer distribution and formalized in USPTO Provisional Patent Application No. 64/043,650, filed April 19, 2026, titled 'System and Method for Multi-Criteria Grading, Quality Certification, and Industry-Specific Matching of Recycled Plastic Resins for Secondary Industrial Supply Chain Distribution,' by the corresponding author through Maja World Wide LLC — a secondary polymer distribution company serving 500+ industrial clients across 15 US states at volumes exceeding 3,000 metric tons per month. The six evaluation components are: (1) visual inspection for color, contamination, moisture, and odor; (2) polymer type verification through density and melt behavior testing; (3) physical form classification into pellets, regrind, bales, or rolls; (4) technical parameter testing including Melt Flow Index (MFI) per ASTM D1238 and density per ASTM D792; (5) processing behavior assessment through extrusion or injection molding simulation; and (6) supplier reliability scoring based on historical performance data. The protocol is demonstrated to identify processing defects in 12–15% of incoming batches that pass visual inspection and physical testing alone, confirming the critical contribution of processing behavior assessment as a distinct evaluation component. Supplier reliability scoring is demonstrated to provide predictive quality signals 45–90 days before explicit batch non-compliance events in approximately 67% of cases. The protocol provides a practically validated, operationally deployable quality assurance framework for secondary polymer distributors seeking to improve industrial buyer confidence and recycled resin adoption rates in support of US circular economy objectives.
