Recycling construction and demolition waste is profitable and environmental way to produce aggregates and reuse valuable materials that would otherwise be disposed. Processing the waste near the worksites also reduces the need for truck transportation resulting in lower logistics costs. Make use of material that would otherwise be waste.

Concrete Recycling: Hardened Concrete. Part of what makes the concrete waste disposal and washout service so essential is that it prevents the hardening of concrete in the equipment. The last thing you need is hardened concrete inside the drums or chutes of your trucks. This is why a washout is needed after each day of work.

returned concrete. 2.2.2 Re-use and Recycle Concrete Wash Water is generally stored on-site at a concrete batch plant in settling ponds and tanks and is recycled into the concrete batching system. This process is advisable as it also reduces the requirement for clean mains water in the concrete batching process.

Recycled aggregates (RA) from construction and demolition waste (CDW) instead of natural aggregates (NA) were analysed in the manufacture of new eco-friendly concrete. Fine (FRA) and coarse (CRA) recycled aggregates were used in different percentages as substitutes of natural sand and gravel, respectively. The results revealed that the use of RA in percentages of up to 50 wt.% is feasible

Your best solution for excess concrete materials at any concrete plant starts with simply addressing the issue, and developing a plan. Without a plan, your pile of “concrete waste” will likely continue to grow. With a well thought-out plan, you’ll find operational, compliance, and financial benefits you likely aren’t receiving now.

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.

The life cycle of a recycled concrete product is divided into four phases based on where a process is taking place. The first phase (source/plant) takes in the production of all of the raw materials except for the RA and DCLs. The second phase occurs in a recycling plant where the waste concrete is processed and crushed into RA and DCLs.
