Three generations of the Grossman family have been in the recycling business since the early 1920's when Benjiman Grossman first started a recycling business  just south of downtown in Columbus Ohio . Over the years, along with his three sons, Arnold, Herbert, and Marvin, the business  grew to a number of recycling and related businesses, each set up to process a specific type of material.  The Ohio Waste Paper Division handles  paper & cardboard recycling, while Recycling Exchange South and Recycling Exchange North specialize in recycling non-ferrous metals, plastic, and glass. The Rose Wiping Cloth division processes textiles for the automotive and manufacturing industries.  A division called Converting Technologies manufactures customized paper products for the hotel, restaurant, and automotive industries.  The Grossman Exports division processes and ships used clothing to ports around the world. By April of 1998, all Grossman recycling divisions except Recycling Exchange North were sold, spun off or relocated outside of Ohio.
