Concrete can be recycled by breaking up or crushing the concrete for use in other concrete applications. Recycled concrete uses include bulk fill, road construction, bank protection, filler in drainage structures and aggregates to produce new concrete.
Recycling concrete keeps large amounts of the material out of landfills. Recycling also reduces the amount of new aggregate material used, which helps protect resources. The size of the crushed concrete depends on the eventual use of the product. The recycling process involves removing any steel used for reinforcement or other items embedded in the concrete. Recycling concrete also requires attention to ensure contaminants, such as asphalt, wood or sealants, are removed.
