Meaning
Regulatory approvals for plastics intended to contact food must satisfy stringent toxicological and migration criteria set by European authorities. Achieving EFSA compliance requires recyclers of polyethylene terephthalate and other polymers to demonstrate that their decontamination processes reduce contaminants below hazardous thresholds. This validation is essential for commercializing recycled food packaging.
Safety Assessment
Exposure limits and migration models form the basis of the evaluation of recycled materials. To secure EFSA compliance, a process must go through a challenge test where the polymer is intentionally contaminated with surrogate chemicals and then run through the recycling line to measure the cleaning efficiency. This test proves the system can handle worst case contamination scenarios, ensuring that any residual chemicals are far below the threshold of toxicological concern for human health.
Recycling Protocol
Extruders and decontamination reactors must operate within the validated temperature and vacuum limits established during the challenge testing. Deviating from these setpoints invalidates the EFSA compliance status of the produced resin batch. Continuous monitoring of these variables is necessary to maintain food contact certification.
Market Access
Food packaging manufacturers cannot use recycled polymers in the European Union without certified decontamination lines. While a virgin resin carries a standard declaration, a recycled material requires this specific compliance documentation to be accepted by brand owners. This certification protects the recycler from liability.
