Raising the Bar: UN Experts Advocate for Tougher Safety Standards on Recycled Plastics in Food Packaging

As global efforts to combat plastic pollution gain momentum, recycled plastics are increasingly touted as a sustainable solution for food packaging. But recent warnings from United Nations experts highlight a critical challenge: ensuring public health is not compromised in the pursuit of circularity.

Why the Safety of Recycled Plastics Matters in Our Food Supply

Recycled plastics play a crucial role in reducing environmental impact, supporting sustainability, and promoting resource efficiency. However, without robust safety standards, dangerous chemicals and contaminants can leach from recycled materials into food—a major public health concern that could undermine consumer trust and efforts toward ESG goals. According to UN-appointed specialists on toxics, waste, and human rights, recycled plastics can contain residues and additives that are hazardous if consumed. The current patchwork of safety regulations, varying widely by country and region, is insufficient to address these emerging risks.

Current Regulations: A Patchy Global Landscape

While major economies such as the European Union and the United States have introduced guidelines for the use of recycled plastics in contact with food, “potentially hundreds of different chemicals” may still slip through the cracks due to gaps in testing, oversight, and enforcement. Many low- and middle-income countries lack any comprehensive standard for food-grade recycled plastics, exposing consumers to untracked risks.

Key Risks Associated with Food Packaging Made from Recycled Plastics

• Chemical Migration: Toxins such as phthalates, bisphenol A (BPA), and flame retardants can migrate from packaging into food products.
• Unknown Additives: Legacy additives from the original material or contaminants introduced during improper recycling processes.
• Insufficient Traceability: Difficulty tracking the lifecycle and composition of recycled plastics increases the chance of contamination.

Ingesting these substances has been linked by researchers to a range of health concerns—from hormone disruption and developmental issues to cancer—putting the spotlight on the urgent need for international action.

UN Recommendations for Protecting Health and the Planet

UN experts call for a harmonized global framework that guarantees the safety of recycled plastics used in food packaging. Key pillars of their recommendations include:

• Mandatory Safety Assessments: All recycled plastics intended for food contact should undergo thorough, science-based risk evaluations.
• Disclosure and Transparency: Full supply chain traceability and ingredient disclosure are vital to consumer safety.
• Phasing Out Hazardous Chemicals: Proactive removal of substances known or suspected to be harmful from the recycling stream.
• Investment in Innovation: Supporting advanced recycling technologies and materials that minimize dangerous residues.

Such measures not only protect human health but also bolster confidence in recycled materials, an essential component for the transition to a sustainable, circular economy.

Building a Safer, More Sustainable Future

Industry leaders, governments, and brands can take proactive steps by adopting best practices for material sourcing, engaging in transparent supply chains, and investing in certifications and testing. Organizations embracing sustainability frameworks and prioritizing food safety will earn greater trust from informed consumers. Furthermore, consumers can help drive change by demanding transparency in packaging materials and supporting companies that uphold the highest health and environmental standards.

How Businesses Can Respond

• Audit plastic supply chains for potential hazards.
• Invest in modern, closed-loop recycling systems with rigorous quality control.
• Engage suppliers in continuous improvement on safety standards.
• Seek third-party certification or compliance with global food safety regulations.

Stakeholders interested in scaling their ESG and sustainability programs or improving energy efficiency can find a wealth of solutions to support more responsible packaging initiatives.

Join the Movement for Safer Packaging

The transition to a circular economy must not come at the cost of consumer safety. By prioritizing strong, evidence-based regulations, collaborative innovation, and transparent practices across the plastic recycling sector, we can realize a future where food packaging is both safe and sustainable.
