This article just came up in my news feed. I thought you’d all like to read it. I will point out that C&D-specific MRFs have told me that they are really good at single-stream C & D waste, as long as the drywall is pulled out. Any drywall in a single-stream C & D dumpster ends up in the landfill. Drywall just breaks apart and gets contaminated in single-stream C & D dumpsters.

and the documentary https://www.plasticchina.org/ is worth watching, if you haven’t seen it already. It’s referenced in the article and apparently now banned in china. warning: definitely not a feel-good movie.
