As part of our Innovation Spotlight series, Control Union explains how integrated third-party certification can turn regulatory pressure from legislation such as the EU’s Packaging and Packaging Waste Regulation (PPWR) into measurable value.
The EU’s Packaging and Packaging Waste Regulation (PPWR) entered into force on 11 February 2025, with most provisions biting from 12 August 2026. For brand owners, CSOs and converters, the next 12 months will decide whether packaging becomes a compliance liability or a competitive edge.
Europe generates 186.5 kg of packaging waste per inhabitant each year, up by 21% since 2011. Plastic alone accounts for 16 million tonnes, yet only 41% of that plastic packaging is recycled, despite targets rising to 65% by 2025 and 70% by 2030.
The PPWR raises the bar further:
Add in the Single-Use Plastics Directive, which already requires a 25% rPET share since this year, and the stakes are clear: failure to substantiate recyclability claims will carry hefty penalties and could erode brand trust on the European market.

A portfolio of independent packaging and plastics certifications offers a practical way to address the core compliance challenges posed by the PPWR. These systems align directly with the regulation’s key articles, providing businesses with verified documentation and traceability across the supply chain.

By bundling several certifications into one combined audit, brand owners can typically half auditor costs. A certification body with global reach can provide additional efficiency that scales across borders. European headquarters can get their international converters audited under PPWR-aligned systems, smoothing compliance from initial pack design all the way to final distribution.
The PPWR window is closing fast. Third-party certification can turn the regulatory countdown into a business advantage and protect your brand, lower costs and substantiate your sustainability promises to stakeholders. Engage a trusted and reliable certification body like Control Union that can combine audits and provide their certification services for your whole supply chain.
