REVIEW OF STRATEGY FOR RECYCLING AND REUSE OF WASTE .

Recycling of process water is a common feature of UK ready mixed concrete plants. Water from washing out trucks is recovered from the wash out pit and stored in a settling pit. Run off water from the yard will also drain into this settling pit. The water in the settling pit is allowed to overflow into a second and possibly a third pit.

Civil Engineering 101: Why Should We Recycle .

When concrete is recycled, the landfills where they are supposed to be dumped are cleared, thus reducing the need for more landfills. Concrete is non-biodegradable and takes a lot of landfill space. Recycling concrete into usable aggregate also consumes less energy compared with processing new stone for construction of buildings and structures.
