Taking Recycling to New Heights
Posted: April 20, 2022
Delmon Readymix has completed a major upgrade to their concrete recycling facility at their Salmabad production location. 100% of the waste concrete generated through the cleaning of the transit mixers and concrete pumps, along with any concrete returned from customers sites, is now fully recycled with no materials going to landfill.
A two stage process, which includes a Bibko concrete reclaimer and a Matec filter press, first separates out the aggregate and sand from the waste concrete. This cleaned aggregate is then used in the production of fresh concrete, giving a saving of up to 1,000 tonnes of virgin aggregate per month, thus enhancing the environmental impact and starting the process of carbon reduction in the production of concrete.
The remaining cement and water slurry is separated using the filter press. From the filtering process we obtain two components with the first being a dried cement cake which is used as a recycled fill material, the second component is clean water which is used in the production of fresh concrete, saving 10,000 litres of water per day and helping Delmon to achieve sustainability, taking the next steps to having environmentally friendly concrete plants.
