Minimizing the environmental impacts of plastic through eco-design
AI summary Read the abstract
Researchers developed a sustainability metric for eco-designing plastic products with low environmental persistence by integrating the environmental degradation rate of plastics into established material selection frameworks. The approach allows designers to compare materials on both functional performance and environmental persistence using material property indices.
While plastic pollution threatens ecosystems and human health, the use of plastic products continues to increase. Limiting its harm requires strategies when designing plastic products informed by the threats plastics pose to the environment. Thus, we developed a sustainability metric for the eco-design of plastic products with low environmental persistence and uncompromised performance. To do this, we integrated the environmental degradation rate of plastic into established material selection strategies, deriving material indices for environmental persistence. By comparing indices for the environmental impact of on-the-market plastics and proposed alternatives, we show that accounting for environmental persistence in design could translate to societal benefits of hundreds of millions of dollars for an individual consumer product. Our analysis identifies which materials deserve adoption and investment to create functional and less environmentally impactful products.

Methodology to address potential impacts of plastic emissions in life cycle assessment
AI summary Read the abstract
Researchers proposed a new method for including the environmental impact of plastic emissions in life cycle assessments, which currently tend to make plastic products appear less harmful than alternatives. The approach introduces characterization factors based on how long different plastics persist in the environment. The study suggests that accounting for plastic pollution in these assessments could significantly change how the environmental footprint of plastic products is evaluated.

Method for quantification of microplastic release from plastic-based materials during weathering
AI summary Read the abstract
Researchers developed a method to quantify microplastic release from plastic-based materials during weathering, responding to the need for limits on how much MP a product can release over its lifetime. The method enabled standardized measurement of MP generation from photodegradation during product use and end-of-life mismanagement.
