Tens of thousands of pieces of plastic littering the planet come from just a handful of multinational corporations, an environmental pressure group said yesterday. Coca-Cola, Nestle and PepsiCo were named by Break Free from Plastics, a global coalition of individuals and environmental organisations, who warned the companies largely avoid cleanup responsibility. The coalition’s volunteers collected nearly half a million pieces of plastic waste during a coordinated “World Clean Up Day” in 51 countries a month ago, of which 43 percent were marked with a clear consumer brand. For the second year in a row, Coca-Cola came out on top. Others in the top ten polluters include Mondelez International, Unilever, Mars, P&G, Colgate-Palmolive, Philip Morris, and Perfetti Van Mille, the report added.
