THE HAGUE — Hoping to reduce one of the most ubiquitous forms of waste, a global group of scientists is proposing that certain types of plastic be labeled hazardous.
The group, lead by two California scientists, wrote in this week’s issue of the scientific journal Nature:
We believe that if countries classified the most harmful plastics as hazardous, their environmental agencies would have the power to restore affected habitats and prevent more dangerous debris from accumulating.
While 280 million tons of plastic were produced globally last year, less than half of that plastic has ended up in landfills or was recycled, according to the scientists’ data. Some of the unaccounted for 150 million tons of plastic is still in use, but much of it litters roadsides, cities, forests, deserts, beaches and oceans. (Just think of the great floating garbage patches at sea).
Unlike other forms of solid waste, such as uneaten food, scrap metal or last year’s clothes, plastics take an especially long time to break down. And when they finally do, they create hazardous, even toxic particles that can harm wildlife, ecosystems and humans.
For now, the group — led by Chelsea M. Rochman of the School of Veterinary Medicine at the University of California, Davis, and Mark Anthony Browne at the National Center for Ecological Analysis and Synthesis in Santa Barbara, California — is calling for the reclassification of plastics that are particularly difficult to recycle and that are most toxic when degrading: PVC, polystyrene, polyurethane and polycarbonate.
The scientists say these types of plastics — used in construction, food containers, electronics and furniture — make up an estimated 30 percent of all plastics produced.
Join our sustainability conversation. Does it make sense to re-classify common plastics as hazardous, or are there better ways to reduce the amount of plastics we throw out?
