Ever wonder how the jumble of recyclables tossed in your one-bin-takes-all cart gets sorted so it all can be shipped off to become new products? The answer is inside a building in Howard County which receives much of the recyclable material collected in Frederick County. Winding through the 50,000 square-foot Recycle America plant off U.S. Route 1 in Elkridge is an ingenious array of conveyor belts interspersed with a series of staged mechanical and magnetic filters. The apparatus fills most of the structure and separates most stuff stashed in the carts that Frederick residents have been wheeling to the curb since the county expanded its recycling program to a single stream system in 2009. At the plant — one of several in Maryland owned by Waste Management, the world’s largest collector and marketer of recyclables — workers first weigh each load and record where it came from. Then all the material goes onto a conveyor belt where workers watch for large items and plastic bags and remove those by hand. Tons of paper, cardboard, metals, glass, plastic run down the belt to rows of rotating disks gauged to sort materials by pushing some items over the top and allowing others to fall through and move for further sorting. Large pieces of cardboard are snagged early and sent to storage for baling.
