And a reminder--If you want to reach out to them privately, rather than through the forum, with your message, you can see anyone's email address by... Read more

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.
