Concrete recycling is becoming an increasingly popular way to utilize aggregate left behind when structures or roadways are demolished. In the past, this rubble was disposed of in landfills, but with more attention being paid to environmental concerns, concrete recycling allows reuse of the rubble while also keeping construction costs down.
Recycling of concrete pavement is a relatively simple process. It involves breaking, removing and crushing concrete from an existing pavement into a material with a specified size and quality. Crushed concrete may be reused as an aggregate in new Portland cement concrete or any other structural layer.
One such measure is to reuse, reduce and recycle of waste materials. Thus by making proper use and recycling the optimization of resources can be achieved. Reuse, reduce and recycle serves dual purpose – it doesn't just make the waste reusable, but also prevent pollution to some extent.
Recycling concrete helps reduce construction waste and extend the life of landfills as well as saving builders disposal or tipping fees. It also reduces transportation costs because concrete can often be recycled in areas near the demolition or construction site.
This authoritative reference work provides a comprehensive review of the management, recycling and reuse of waste composites. These are issues which are of increasing importance due to the growing use of composites in many industries, increasingly strict legislation and concerns about disposal of composites by landfill or incineration.

I get the question on is concrete hazardous waste a lot, and while the answer seems pretty clear to me, for some reason, it keeps coming up.Let's take the question of is concrete a hazardous waste, or the hazardous nature of concrete, one step at a time.
In general, the reuse and recycle of construction waste is concentrated in the preparation of recycled aggregate for concrete. By adding a portion of recycled aggregate instead of natural aggregate coarse into the mixture, producing the recycled concrete, which can conserve energy and materials for concrete production.
