single-sort recycling
n.— «One means of increasing the rate is a user-friendly method called “single-stream,” or “single-sort” recycling. All commodities, usually with the exception of cardboard, which is fetching about $100 per ton, are dumped into a single bin at the recycling center. That means the consumer can use a single bin at home, which in theory makes it easier for people to recycle.» —“Easier Recycling” Bangor Daily News (Maine) Nov. 12, 2007.
