With plastic pollution posing a significant threat to ecosystems and human health, various strategies to lessen this type of pollution include reducing the production of plastic, decreasing the generation of plastic waste, and improving the material and product design of plastic items.
Now, researchers have developed a sustainability metric for the ecological design of plastic products that have low persistence in the environment. Adhering to this metric could provide substantial environmental and societal benefits, according to a new study led by researchers at the Woods Hole Oceanographic Institution (WHOI), and published in the journal ACS Sustainable Chemistry & Engineering.
“While plastic pollution threatens ecosystems and human health, the use of plastic products continues to increase. Limiting its harm requires design strategies for plastic products informed by the threats that 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,” according to the study.
Designing single-use plastics using this approach can have a substantial impact. Analyses in the study say switching to alternative materials for single-use coffee cup lids, such as cellulose diacetate and polyhydroxyalkanoates, could reduce the environmental costs to society by hundreds of millions of dollars.
