I've been hauling and disposing demolition for years, and more and more of my customers are recycling!!! It seems to me, that if a company has the time and resources, there is a lot to be recycled:
Scrap Metals
clean wood
Large Timbers
Glass
Concrete
Drywall (because of the oder, more landfills are rejecting large quantities)
Greean Waste (around or on site)
