Martin Paterson, Chief Commercial Officer of the Dutch company everox, gave an outstanding presentation at the World Cement Association (WCA) Annual Conference in Bangkok in April about the “The next generation of building materials”. everox patented a process, which separates concrete waste completely into its initial ingredients: Gravel to recycled coarse aggregates, sand to recycled fine aggregates, quartz to fine inert filler and cement paste into Activated Cement Paste (ACP). Due to its highly cementitious properties, the ACP can be used as a low carbon SCM in newly produced cement or concrete. A flagship plant for 100.000 tons of concrete waste per year is under execution in Rotterdam, The Netherlands. The facility (illustration) is scheduled to be operational by 2027. The EU alone faces about 180 million tons of concrete waste annually.
