Minimizing the Environmental Impacts of Plastic Pollution through Ecodesign of Products

This article examines how environmental persistence can be incorporated into the design of plastic products and explores why the time a material remains in the environment should be considered alongside traditional sustainability metrics such as cost, greenhouse gas emissions, and resource use.

Using an engineering-based ecodesign framework, the authors compare conventional plastics with alternative materials and evaluate how material properties influence environmental lifetime, product performance, and overall environmental impact. The analysis includes practical case studies and discusses how degradation behavior can inform future material selection and product design.

A key finding is that cellulose diacetate emerges as one of the most promising materials for reducing the long-term impacts of plastic pollution because it combines functional performance with relatively low environmental persistence. In the evaluated design scenarios, cellulose diacetate performed substantially better than several commonly used plastics when environmental lifetime was included as a design criterion, while remaining competitive across other sustainability considerations. The study suggests that incorporating persistence into product development, regulatory assessment, and material selection could help reduce the societal and environmental costs associated with mismanaged plastic waste. For cellulose acetate, the findings highlight the importance of continued research into degradation behavior and support its consideration in applications where both performance and reduced environmental persistence are relevant.
