Mismanaged waste and tyre abrasion: scientists map key types and sources of marine plastic pollution
There is mounting global concern about marine plastic pollution and a growing
focus on ways to address this environmental problem. In 2015, 9.2 megatonnes
(Mt) of plastic was lost to the environment globally; in order to remedy this
issue, it is essential to quantify the amounts, types and sources of plastic
waste in the global environment (both geographically and within industry). This
study estimates the loss of plastics to the environment across the plastic value
chain, finding that mismanagement of municipal solid waste and tyre abrasion are
key contributors of macro- and microplastic waste, respectively.
