ALLU and MAPEI are announcing their cooperation within concrete recycling

ALLU MAPEI Circulus* is a solution to transform returned concrete into a high-quality recycled aggregate. The immensely mobile and industrially efficient method has a strong impact on the environment and business. 


ALLU and MAPEI are both world class leading companies in their respective fields with global distribution networks. Through the cooperation customers will have access to the highest level of knowledge within concrete recycling.

The ALLU MAPEI Circulus system is aimed at large and medium sized RMC producers or cement/concrete recycling companies who wish to reduce the cost of handling returned concrete waste. Besides the positive environmental effects, through less new material needed, the system will generate substantial savings in production. Savings of up to tens of Euro’s per cubic meter of concrete produced are achievable through savings towards landfill cost and reduced costs for virgin aggregate.

The system is simple and requires minimal investments: the MAPEI Re-con Zero- chemical and an ALLU Transformer. With Re-Con Zero the wet returned concrete is transformed into a dry granulate. The ALLU Transformer then processes the hardened lumps and screens them into the specified aggregate size to be recycled with fresh concrete. A concrete manufacturer may then use between 5% and 30% of the recycled aggregate with new concrete. This will bring significant savings to the cost of buying virgin aggregate. The system also greatly reduces the amount of washed out sludge from concrete trucks. Waste sludge is an environmental challenge as it must go to a landfill and is therefore an additional cost for concrete producers.

The ALLU MAPEI Circulus system assists the concrete industry towards sustainability in concrete manufacturing. The global consumption of concrete is a staggering 23 Billion tons per year, and it is estimated that approximately 2% of all concrete produced in the world is returned to the producer. The majority of this ends up on a landfill. An estimated five (5%) percent of all man-made carbon dioxide emissions stem from cement and concrete production. Two (2%) percent of produced and returned concrete adds up to 460 million tons being unnecessarily put on landfills, resulting in a staggering total of 53 million tons of carbon dioxide being emitted. With the ALLU MAPEI Circulus, there is an opportunity to save up to 96% on the above-mentioned CO2 emissions.
