Canadian municipality: SunChips bags degrade too slowly
A Canadian municipal composting program is telling consumers not to place SunChips bags in composting bins because they take too long to break down. SunChips, from the Frito-Lay unit of PepsiCo, switched early this year in Canada to bags made from 100% polylactic acid (PLA). The Green Bin Program of Canada’s Niagara Region has a network of bins for compostable material. However, Niagara Region authorities recently told the Fort Erie Times that SunChips bags take 14 weeks to biodegrade, which is too long; single-layer compostable trash bags take only three to four weeks. The Niagara Region is advising consumers to discard SunChips bags with regular trash.
