Check it New Yorkers, the city has a site to match commercial waste to people who could put that crap to use and sells it to them on the cheap. It’s win-win: cheap stuff for the citizen, less waste for the city to haul.
The site lists neat stats on total cost savings, tonnes of trash averted and numbers of members and exchanges. The numbers date back to 1998, which leads one to believe this little-known-service has been around for a while but is just now getting a tech refresh. Does your community have something like this?
