There are a variety of benefits in recycling concrete rather than dumping it or burying it in a landfill.
13 Advantages and Disadvantages of Recycling
List of Disadvantages of Recycling. 1. More pollution and energy consumption. It’s contradicting, but the reality is that recycling tons of garbage will require waste to be transported, sorted, cleaned and processed in separate factories, all of which need energy and may result in by-products that can pollute air, water or soil.
What to do with "concrete waste" at any type of
Recycle excess concrete materials. There are ample opportunities now to recycle. Plastic concrete can be put through a concrete reclaimer to make aggregate suitable for further concrete production. Hardened concrete can be crushed to make an excellent base material with a lot of great uses today.

ENVIRONMENTAL IMPACT OF CONCRETE RECYCLING, COMING FROM
the recycling of concrete originating from construction and demolition waste (C&DW). The aim of the study was to implement a life cycle inventory (LCI) of the concrete recycling phases. It was carried out in Spain, with data collected from the various recycling processes involved in the mobile crushing plants operating in Catalonia.
Innovative process routes for a high-quality concrete recycling
Recycling concrete waste as recycled aggregate is one of the methods to reduce the concrete waste. Therefore, this paper investigates the economical considerations in recycling concrete waste.
Concrete recycling involves crushing the waste on site with one of our state-of-the-art portable concrete crushers. Waste can then be more easily removed during a site clearance. After crushing and removal, the material goes through a screening process at our fully licensed recycling and sorting facility, where concrete, rebar and other ...
