Most Americans say they want the U.S. to achieve “zero waste,” or at least minimize waste going to landfills, but most of them think it will be more than four decades before that happens, according to a survey taken on behalf of the Glass Packaging Institute (GPI). The survey, taken in early April by Opinion Research, said 57% of the respondents would like the country to achieve zero waste in 20 years. However, 53% said they believe it will take 41 years or more to achieve that goal. GPI is touting the poll in advance of Earth Day, April 22, to stress that glass is one of the few widely used packaging materials that can travel in a true closed loop from recycling to new containers and back again.
