Heavy concrete crushing equipment easily pulverized blocks of concrete into fine particles Thursday morning as part of a demonstration at Orangeburg’s Sunshine Aggregate LLC. The company recycles concrete, brick and asphalt, and sells the crushed material in an effort to reduce the landfill load and meet the demand for concrete, Sunshine Recycling owner Joe Rich said. The company is currently operating about six tractor-trailers for the pick-up and transport of concrete, Rich said.
