Dutch Researchers Create Tool to Help Companies Navigate Complex Packaging Sustainability Decisions
Wageningen, Thursday, 9 April 2026.
Wageningen University unveiled a groundbreaking decision-making framework that challenges the assumption all packaging is environmentally harmful. The tool evaluates three critical environmental impacts: climate change, pollution, and biodiversity loss, while balancing social and economic factors. Researchers highlight surprising trade-offs, such as glass milk bottles producing higher CO₂ emissions than cardboard cartons, despite being less harmful if discarded in nature. The framework addresses industry demand for evidence-based guidance beyond simple elimination strategies, recognizing that packaging often prevents food waste and serves essential protective functions in modern supply chains.
Three-Factor Environmental Assessment Framework
The decision tool, developed by Wageningen researchers Ulphard Thoden van Velzen and Marieke Brouwer, evaluates packaging sustainability across three critical environmental dimensions [1]. The framework specifically targets climate change through CO₂ emissions analysis, planet pollution via non-degradable adhesives and microplastics assessment, and biodiversity loss through deforestation impact evaluation [1]. This comprehensive approach moves beyond single-metric assessments that often lead to unintended consequences, such as choosing non-degradable plastics or cardboard requiring deforestation when focusing solely on carbon emissions [1]. The tool was presented on April 8, 2026, as part of the “Kennis-op-Maat” project, responding directly to food industry demands for evidence-based packaging guidance [1].
Economic and Social Balance Considerations
Beyond environmental metrics, the Wageningen framework incorporates social and economic factors that complicate packaging decisions [1][3]. The tool recognizes that packaging can generate convenience and profit while simultaneously creating costs or disadvantages for consumers, workers, or businesses [3]. These effects often prove contradictory, making trade-off evaluations complex but essential for sustainable decision-making [3]. The researchers emphasize that sustainable packaging must protect products while minimizing negative impacts and maintaining social-economic equilibrium [1]. This holistic approach addresses the reality that packaging decisions affect multiple stakeholders across supply chains, from producers to end consumers.
Real-World Trade-offs Challenge Simple Solutions
The decision tool reveals counterintuitive findings that challenge conventional packaging wisdom through concrete examples [3]. Glass milk bottles score worse on CO₂ emissions compared to beverage cartons, yet glass proves less environmentally damaging when discarded in nature [3]. Similarly, thin plastic wrapping around cucumbers generates additional CO₂ emissions and pollution risks but extends shelf life, preventing food waste [3]. Researcher Marieke Brouwer acknowledges that unnecessary packaging exists, particularly for non-food products like scissors wrapped in hard plastic and cardboard, suggesting simple string alternatives would suffice [1]. However, Thoden van Velzen counters that pre-cut fruit in plastic containers can mean the difference between children consuming fruit or not eating it at all [1].
Industry Implementation and Future Impact
The “Duurzaam Verpakken” (Sustainable Packaging) guide serves as a reference tool for packaging experts and professionals to determine optimal packaging choices per situation [1]. The framework was developed through the “Kennis op maat” program, initiated in 2020 to facilitate knowledge transfer to small and medium-sized enterprises in agriculture, water, and food sectors [1]. The tool addresses growing regulatory pressures, as companies face new requirements under the Packaging and Packaging Waste Regulation (PPWR), mandating recyclate use in packaging by 2030 [6]. Industry collaboration continues expanding, with SFA Packaging from Middelharnis partnering with Wageningen Food & Biobased Research and three other companies to develop the world’s first transparent, biobased injection molding packaging [2].
