ISO 22095 Mass Balance Chain of Custody Audit Requirements
ISO 22095 mass balance audits demand strict site boundaries, verified baseline yield conversions, and zero negative credit balances across accounting periods.
Free Allocation Caps
Meaning
A regulatory limit defines the maximum volume of sustainable material attributes that a manufacturer can assign to a product line without physical tracking. These free allocation caps restrict the over-allocation of recycled claims to high-margin polymer grades. Producers must operate within these boundaries to maintain the integrity of their mass balance declarations.
Material Efficiency
Plastics manufacturers rely on chemical recycling to generate certified feedstocks. Because of free allocation caps, a factory cannot claim that an entire production batch is composed of recycled material if the feedstock input does not justify it. This limit ensures that the physical dilution of recycled monomer is accurately represented in the final molded parts.
Keeping allocation levels below the cap prevents the artificial inflation of recycled polymer grades on datasheets. When processors respect these boundaries, they maintain the credibility of the entire material supply chain and avoid audit failures during certification reviews.
Production Limit
Operational constraints within the compounding line dictate how credits are distributed across different product families. Moulders operate under free allocation caps to avoid concentrating all recycled claims on a single high-performance grade while leaving commodity resins uncertified. This distribution constraint forces a more uniform utilization of sustainable polymers across the factory floor.
When a run exceeds the cap, excess volumes must be sold as standard grade.
Financial Consequence
Compliance with these ceilings influences the pricing strategy for sustainable resins. When free allocation caps are exceeded, the inability to apply further recycled credits reduces the premium that can be charged for subsequent batches. This directly impacts the return on investment for chemical recycling facilities.
