Reuse Expansion Seen as Key to Mitigating Packaging Supply Risks
Although there is currently no direct large-scale substitute for PE in food packaging, experts suggest that reducing dependence on single-use plastics may be a more practical strategy than seeking one-to-one material replacements. In this context, expanding reuse systems is increasingly viewed as a viable way to strengthen supply chain resilience and reduce exposure to raw material shocks.
Established Reuse Models Demonstrate Feasibility
Across different regions, functioning reuse systems provide evidence that alternative packaging models can operate effectively. For example, Germany’s deposit-return system for reusable bottles achieves exceptionally high return rates, supported by strong infrastructure and consumer participation.
Elsewhere, traditional practices continue to play a role. In parts of Asia, reusable food containers and tray-based serving systems remain common, while refillable formats and low-waste distribution methods persist in local markets. These examples highlight that reuse is not a new concept but a proven approach that can be scaled under the right conditions.
Retail and Policy Initiatives Drive Adoption
Efforts to expand reuse are gaining traction in both policy and commercial sectors. In the United States, pilot programs are testing return-and-reuse models in retail, starting with localized applications such as prepared food packaging.
Meanwhile, Europe is advancing regulatory targets through its Packaging and Packaging Waste Regulation (PPWR), which sets phased goals for increasing reusable packaging. These include measurable targets for beverage containers, requirements for refill infrastructure, and obligations for businesses to accommodate reusable formats.
Such coordinated actions suggest that combining reuse, reduction, and improved waste management could significantly lower overall plastic pollution in the coming decades.
Reducing Unnecessary Plastic Use
In addition to reuse, eliminating avoidable plastic packaging represents another important strategy. A recent U.S. survey of grocery stores found wide variation in packaging intensity across similar fresh produce categories, indicating that best practices already exist and could be more broadly implemented.
This variation suggests that significant reductions in plastic use are achievable without compromising product availability, simply by optimizing packaging choices and minimizing excess materials.
Moving Toward Scalable Solutions
To support the transition, industry frameworks and guidance are emerging to help organizations design and implement reuse systems. These tools address system design, logistics, stakeholder coordination, and enabling policy conditions—helping move reuse from pilot projects to scalable solutions.
