The push to establish a circular economy has gained traction over the past year, driven by the European Commission's initiatives outlined in 2022 for EU packaging regulations. Sparking considerable debate, this initiative prompted associations and businesses in the packaging industry to progress towards a circular economy through innovative developments.
The circular economy took centre stage at this year's interpack, with numerous exhibitors showcasing solutions for efficient recycling and incorporating recycled materials in packaging production. Markus Rustler, President of interpack and CEO of Theegarten-Pactec, underscored the importance of sustainable packaging materials while acknowledging the challenges faced by the industry, especially in regions like Asia, Africa, and South America, where a functioning circular economy is yet to be established.
The European Commission proposed the Packaging and Packaging Waste Regulation (PPWR) in response to the urgency to minimise non-recyclable waste. The regulation aims to set binding requirements for packaging across all materials in the EU market, with goals such as preventing packaging waste, establishing a closed recycling loop, and reducing the demand for primary raw materials.
Amidst these regulatory developments, industry players are independently driving initiatives towards a circular economy. Plastics Europe, the association of European plastics producers, released an action plan for plastics production without fossil resources. This "Plastics Transition Roadmap" outlines a strategy to replace 65 percent of fossil resources in plastics production with circular feedstocks by 2050.
Companies like Greiner Packaging and Joma are actively contributing to sustainability efforts. Greiner Packaging, for instance, focuses on reducing plastic usage with innovative solutions like the K3 r100, a cup designed for easy recycling. Meanwhile, Joma showcased a spice grinder made from 100 percent recycled PET, contributing to a circular economy.
Innovations extend beyond plastics, with SIG developing a full-barrier packaging material for drinks cartons that eliminates the need for an aluminium layer. This aligns with 4evergreen's Circularity by Design Guidelines, emphasising sustainable beverage packaging design.
Addressing the need for transparency in the packaging supply chain, GS1 Germany collaborated with stakeholders to develop Circular Plastics Traceability guidelines. This data-driven approach enables consistent data sharing for tracking the journey of each plastic through the recycling loop.
Technological advancements, such as Polysecure's Sort4Circle sorting technology, contribute to efficient recycling by separating polyethylene packaging into specified fractions.
Research projects are exploring renewable raw materials, as seen with Brabender and Dresden University of Technology using marine algae to produce biodegradable film. This material, Carraphane, exemplifies circular economy principles by minimising resource usage and environmental impact.
As the industry moves towards a circular economy, regulatory debates, independent initiatives, and technological advancements shape the trajectory of sustainable practices in the packaging sector. The proposal for the PPWR faces ongoing debate, with uncertainties about its completion before the European elections in June 2024.
