Vessels made from polystyrene have been keeping coffee and other foods toasty warm for decades, but due to deep environmental concerns Highland Park is considering banning use of polystyrene cups, bowls, and plates in restaurants and in businesses. However, some question whether banning the versatile and cheap material is the right answer to the region's landfill problems. Some have suggested streamlining or producing more viable, technologically advanced methods of recycling and reusing polystyrene materials:
Tanya Triche, senior counsel for the Illinois Retail Merchants Association, has followed the debate in Chicago and Highland Park and questions whether alternative products will solve the problem. "If the goal is to get PSF (polystyrene foam) out of landfills, all you are really doing is replacing it with something else that is going into the landfill," said Triche, who suggested that communities build recycling facilities. "Banning something, we really don't feel is the best way to tackle the issue," she said.
