Construction and demolition (C&D) recycling is the practice of salvaging, recycling and reusing materials and debris generated during construction, renovation and demolition of roads, bridges and buildings. C&D materials often contain bulky, heavy materials, such as concrete, asphalt, wood, glass, metals, and other salvaged building components. Asphalt, concrete and rubble are often recycled into aggregate or new asphalt and concrete products as part of the C&D recycling process, while wood can be recycled into engineered-wood products, as well as mulch, compost and others. Metals, including steel, copper and brass, are valuable commodities that can be recycled and resold.
C&D recycling saves contractors money by minimizing both purchase and disposal costs for material. Additionally, C&D recycling is a sustainable method for minimizing the need to extract and consume virgin resources, as well as reducing the amount of material being sent to landfills.
McLanahan Corporation produces equipment needed for all steps of the C&D recycling process including solutions for crushing, pre-sizing, sorting, screening and contaminant elimination. Crushing and screening systems typically start with primary jaws, cones and/or large impactors. The process can then include a variety of secondary crushing and screening equipment to reach the final desired product while removing dirt and other foreign particles. In some cases, such as concrete, further cleaning is necessary to ensure recycled concrete product is free of dirt, clay, wood, plastic and organic materials. C&D recycling equipment from McLanahan can also be used in sorting and separating.
