The cement industry and LafargeHolcim have developed, under the Geocycle brand, strong expertise in coprocessing. This latter refers to the simultaneous recovery of energy and the recycling of mineral materials within one single industrial process: cement manufacturing. This waste treatment solution allows 100% of the material input to be recovered or recycled in the production process without any additional residue or impact on health and cement quality.
In Retznei (Austria), the local cement plant is already amongst the best performer worldwide in terms Waste-to-Energy rate. In 2016, the Geocycle Recycling Center nearby the cement plant settled the benchmark in recycling Construction & Demolition Waste by processing 100,000 tons of C&DW in a year. The pre-treatment platform offers a complete solution for a full C&DW stream, in respect of European waste hierarchy. Retznei plant recovers this stream through co-processing (otherwise it would have been landfilled), mainly clay bricks, so-called “red fraction”, as an alternative raw material.
