Recycled packaging

PPWR and Food Safety: a perfect storm for Food manufacturers

The European landscape of packaging is undergoing a seismic shift with the introduction of the Packaging and Packaging Waste Regulation (PPWR). While the primary objective is to foster a circular economy, it introduces a complex layer of challenges for food manufacturers, who will need to comply with circular packaging obligations while managing the risks associated with Food contact (migration of unknown chemicals, mainly). 

Key Pillars of the PPWR

The PPWR replaces previous directives to harmonize rules across the EU, focusing on the entire life cycle of packaging:

• Waste Reduction Targets: Mandatory reductions of 5% by 2030 and 15% by 2040.
• Mandatory Recycled Content: Specific thresholds for post-consumer recycled (PCR) plastic in food contact materials (FCM).
• Reuse and Refill Obligations: Forcing a shift toward reusable systems for specific beverage and food categories.
• PFAS Restrictions: Limits on “forever chemicals” in food contact packaging to protect public health.

The Evolution of Recyclability Standards

Under PPWR, recyclability is no longer a marketing claim but a technical requirement defined by “Design for Recycling” (DfR) criteria. By 2030, all packaging must meet strict performance grades:

• Harmonized Criteria: Standards are being developed to evaluate packaging based on collectability, sortability, and the absence of “recycling disruptors” (e.g., specific inks, adhesives, or multi-material layers).
• Scalability Requirement: By 2035, packaging must be recyclable “at scale,” meaning the infrastructure for collection and processing must be proven to exist across the EU.
• Material-Specific Protocols: Manufacturers can adhere to rigorous testing protocols (such as 4evergreen/CEPI for fiber-based materials or EN 13432 for compostables) if they want to claim and certify that their packaging truly fits into a circular loop without degrading the quality of the recycled stream. In the very near future, a dedicated Delegated Act will include recyclability criteria for packaging of different materials.

Manufacturer Responsibilities: Compliance and Safety

Food manufacturers are the co-guarantors of the food-packaging dyad. Their responsibilities include:

• Documentary Obligations: Maintaining robust Declarations of Compliance (DoC). Manufacturers must verify, among other things, PFAS concentration, recyclability, and all the requirements listed in the articles 5/12 of the PPWR. 
• Eco-Modulation: Compliance directly affects the bottom line, as EPR (Extended Producer Responsibility) fees are now “modulated”—meaning less recyclable packaging incurs higher financial penalties.
• Uncompromising Safety: Regardless of environmental targets, the General Food Law remains supreme. Manufacturers are liable for any chemical migration or spoilage resulting from new packaging formats.

Critical Food Safety Risks in the Circular Loop

The transition to recycled and alternative materials introduces three primary risks:

• Chemical Migration (NIAS): The recycling process can concentrate Non-Intentionally Added Substances. Impurities from previous lifecycles (household chemicals or non-food plastics) can migrate into food if functional barriers are insufficient.
• Pathogens in Reusable Systems: Reuse models create biological hazards. If containers are not designed to withstand industrial washing, or if material fatigue creates micro-cracks, biofilms can form, leading to cross-contamination.
• Shelf-Life Compromise: Some recycled, monomaterial or bio-based alternatives offer lower oxygen or moisture barriers. This can lead to oxidation, early spoilage, and increased food waste—counteracting the regulation’s environmental goals.

The Challenge of Sourcing: Closed-Loop vs. Open-Loop

A major safety hurdle in meeting PPWR targets is the shift from closed-loop systems (e.g., PET bottles becoming new PET bottles) to open-loop recycling, where materials are sourced from diverse, non-food-grade waste streams.

• Mechanical vs. Chemical Recycling: While mechanical recycling is more energy-efficient, it often struggles to remove deep-seated contaminants from open-loop sources, making it difficult to guarantee food-grade purity.
• Chemical Recycling (Depolymerization): This technique offers a solution by breaking down plastics to their molecular level to remove impurities. However, it remains an emerging technology with high energy demands and requires rigorous validation to ensure that no new chemical residues are introduced during the “rebirth” of the polymer.

The PPWR is a transformative regulation that aligns packaging with the Green Deal. However, for food manufacturers, the “Circular Economy” must remain a “Safe Economy.” Success lies in the integration of Food Safety by Design, where recyclability standards are validated through rigorous chemical testing and a zero-compromise approach to consumer health.
