While demand for polyolefins with recycled content, and in particular rPP approved for food contact applications, continues to rise, these materials remain hard to come by. As yet, neither the European Food Safety Authority (EFSA) nor the Food Standards Agency (FSA) in the UK has approved the use of rPP for food-grade products. This has led an increasing number of consumer goods product and packaging manufacturers to explore other routes, including that known as the mass balance model, a chain of custody option provided under the ISCC Plus certification scheme.
Aptar Food +Beverage is one of the latest to join the ranks of the companies to earn ISCC Plus certification, allowing Aptar Food + Beverage to provide customers with ‘certified recycled content closures at a quality that is similar to that of conventional resin’, said Andreas Traxinger, Plant Manager of Aptar’s Freyung factory. “This is an invaluable benefit to our customers who are working to meet their sustainability goals.”
According to the ISCC, the mass balance approach has been designed to trace the flow of materials through a complex value chain. It is basically a bookkeeping system: since chemically recycled or bio-based feedstocks are typically blended in the manufacturing complex, physical segregation of recycled content is often practically and economically infeasible. The mass balance approach makes it possible to track the amount and sustainability characteristics of batches of material in the value chain and attribute it based on verifiable bookkeeping.
The system ensures traceability, feedstock identity, and can help to validate sustainability claims around recycled content.
Aptar’s Freyung site is the first Aptar Food + Beverage plant to achieve this distinction in Europe. The new ISCC PLUS certification comes in addition to the achievements of the ISO 14001 (environmental), ISO 50001 (energy) and internal Landfill Free certifications.
