Recycling construction waste and minerals
In addition to concrete excavation material, we can also process the construction waste of mineral construction materials, such as bricks, plaster and mortar, in cement production. These construction materials are also very similar to the chemical composition of our raw material.
Further minerals, such as quartz sand from foundries or fly ash from the combustion of coal or biomass, can be used as raw material in cement production. They also serve to manage the quality and composition of the raw material to achieve an optimal and consistent product quality.
As part of the quality assurance, the use of all recycling materials is constantly reviewed. Here, the focus is always on the quality of the products as well as on minimising emissions.
