Dutch Researchers Create Tool to Help Companies Navigate Complex Packaging Sustainability Decisions
Wageningen, Thursday, 16 April 2026.
Wageningen University researchers have developed a comprehensive decision-making tool that challenges the simplistic view that all packaging is environmentally harmful. The tool reveals surprising trade-offs: while glass milk bottles generate higher CO₂ emissions than cartons, plastic wrap on cucumbers actually prevents more environmental damage through reduced food waste than the packaging itself creates. The research emphasizes that sustainable packaging depends entirely on context, with no universal solutions existing across industries.
Researchers Challenge Industry Assumptions with Evidence-Based Guidance
The decision-making tool, titled “Duurzaam Verpakken” (Sustainable Packaging), was developed by Wageningen University researchers Ulphard Thoden van Velzen and Marieke Brouwer as part of the “Kennis-op-Maat” (Knowledge-on-Demand) project [1]. This initiative, which started in 2020, aims to transfer specialized knowledge to small and medium-sized enterprises in the Agriculture, Water, and Food sectors [1]. The booklet serves as a practical reference work for packaging experts and other professionals, moving beyond the common narrative that packaging is inherently harmful to the environment [1].
Real-World Examples Reveal Packaging Paradoxes
The research highlights counterintuitive findings that challenge conventional sustainability thinking. While a glass milk bottle produces higher CO₂ emissions than a beverage carton, glass proves less harmful to the environment if accidentally discarded in nature [1]. Similarly, plastic wrap around cucumbers increases both CO₂ emissions and the risk of planet pollution, yet extends shelf life significantly, preventing food waste that often creates more environmental damage than the packaging itself [1].
Comprehensive Framework Considers Multiple Sustainability Factors
The decision-making framework extends beyond environmental considerations to include positive effects on public health, alongside social and economic factors [1]. Companies often focus exclusively on CO₂ emissions, but the researchers advocate for a broader perspective that considers other environmental impacts such as plastic degradability and deforestation [1]. The tool acknowledges that no universally sustainable packaging solution exists, with the optimal choice varying significantly depending on specific circumstances and applications [1].
