During a demo of an existing building, many items were sorted onsite and sent to a specific recycler. In one case, scrap metal was sorted from the other demo debris and sent to one recycling place. It was then split into copper and brass when unloaded from the truck (the haul tickets have the weight breakdown of each material on it). Can this be considered "scrap metal (copper and brass)" waste with no support documentation needed or "commingled" waste and I need to provide the haul tickets?
