What certifications are essential for sustainable packaging?

Compostable Certifications

Compostable certifications are crucial for verifying that a material can safely and effectively break down in specific composting environments, promoting a circular economy. These certifications ensure that the material will decompose into non-toxic substances without leaving harmful residues .

• TÜV Austria (OK Compost): This certification is widely recognized for its rigorous testing of compostability in both home and industrial settings. TÜV Austria offers two primary certifications:

  • OK Compost Home: Products with this certification are tested to fully break down in a home compost setting within 180 days. This is ideal for thinner materials that decompose quickly .
  • OK Compost Industrial: This certification is for products that require a controlled industrial composting environment with higher temperatures and consistent microbial activity. It ensures the product will break down safely in these facilities, leaving no toxic residue .

• ABA (Australia Bioplastics Association): The ABA offers compostability standards for both home and industrial composting, focusing on the physical breakdown of materials and ensuring no harmful residues are left behind. ABA certification is often paired with TÜV for products distributed globally to meet EU and Australasian requirements .

• BPI (Biodegradable Products Institute): This is a U.S.-based certification for industrial compostability. BPI-certified products are tested to confirm they will break down under industrial composting conditions without leaving toxic residues. It is a key standard for validating compostability in North American markets .

• EN 13432: This is the key European Union standard for biodegradability of packaging. It sets the criteria for a product to be considered compostable in an industrial facility. Third-party certifications like TÜV Austria or DIN CERTCO help validate compliance with EN 13432 .

Recycled Content Certifications

These certifications verify the amount and source of recycled material in a product, promoting the use of post-consumer waste and supporting a circular economy .

• Global Recycled Standard (GRS): The GRS is a leading certification for products containing recycled materials. It verifies the percentage of recycled content (both pre-consumer and post-consumer) and ensures the materials are sourced and processed responsibly through a “chain of custody” audit . This certification is valuable for brands that want to substantiate claims like “made with 50% recycled plastic” .

• Recycled Claim Standard (RCS): This certification verifies that a product contains a specified percentage of recycled materials, ensuring that the recycled content claim is legitimate and traceable through the supply chain .

• FSC (Forest Stewardship Council) – Recycled: This certification is granted to paper products made entirely from post-consumer recycled content, guaranteeing that no new trees were harvested for the product. It is a strong signal of commitment to the circular economy .

Responsible Forestry and Paper Certifications

For paper-based packaging, certifications ensure that the materials are sourced from responsibly managed forests, protecting ecosystems and supporting sustainable forestry practices .

• Forest Stewardship Council (FSC): The FSC is an internationally recognized certification for paper and wood products. It ensures materials are harvested sustainably from responsibly managed forests or are made from recycled content. FSC offers several certifications:

  • FSC 100%: Products made entirely from FSC-certified virgin fiber .
  • FSC Mix: Products containing a blend of FSC-certified virgin fiber, recycled content, and controlled wood sources .
  • FSC Recycled: Products made entirely from post-consumer recycled content .
  • FSC Chain of Custody (CoC): This certification ensures that FSC-certified materials are traceable and kept separate from non-certified materials throughout the supply chain .

• Programme for the Endorsement of Forest Certification (PEFC): PEFC is one of the largest forest certification programs in the world. It works with national organizations to establish standards for sustainable forest management and chain-of-custody for certified products .

• Sustainable Forestry Initiative (SFI): The SFI collaborates with a network of stakeholders to promote healthy forests. It offers certifications for forest management, fiber sourcing, and chain-of-custody to ensure materials are sourced responsibly .

Other Key Sustainability Certifications

Beyond material-specific certifications, there are broader certifications that assess a company’s overall environmental and social responsibility, which is essential for building brand trust and avoiding greenwashing .

The Importance of Certifications

Certifications are essential for several reasons:

• Consumer Transparency: They provide clear, trustworthy information that helps consumers make informed choices about the materials, sourcing, and end-of-life treatment of packaging .
• Avoiding Greenwashing: Certifications offer third-party verification that a product meets specific standards, which is crucial in a market where misleading “green” claims are common .
• Regulatory Compliance: Certifications help brands comply with evolving laws and regulations, such as California’s SB 343, which bans false recycling labels, and the EU’s Single-Use Plastics Regulation .
• Building Brand Trust: Using certified materials and displaying recognized logos on packaging can strengthen brand loyalty by aligning with consumers’ values for environmental responsibility .
