Resource Recovery Corporation was created by 15 West Michigan Foundries over 20 years ago. During a Western Michigan AFS meeting the subject of foundry sand and slag disposal cost was discussed. After the AFS meeting some of the local foundry men got together and created RRC to find ways of reusing spent molding sand and slag. Our mandate was simple, find ways of reducing disposal cost, operate at near zero profit and save natural resources at the same time. In 1991 RRCbegan operations in the Muskegon area by using foundry sand as daily cover at a local landfill. In 1996 RRC began processing spent mold and core sand for asphalt and leachate collection media. Also in 1996 RRCbegan processing slag for asphalt and concrete use. In 2005 RRCachieved inert status for it's processed foundry sand. Since 1991 RRChas recycled more than a million tons of foundry process residuals, cut the cost of foundry residuals management by 2/3 and operates at near zero profit.
