Concrete is one of the most widely used materials in the world of construction. It is used in the construction of roads, bridges, buildings and other infrastructure projects. Concrete is strong, long-lasting and relatively inexpensive, making it a perfect construction raw material. But concrete production is also responsible for a significant amount of waste and emissions, including CO2 emissions. Therefore, recycling concrete is very important for the sustainability of the construction industry and the planet.

Concrete recycling is the process of crushing and reusing concrete waste in new structures. Recycling concrete reduces the emissions associated with the production of new concrete because it requires fewer raw materials and less energy for processing.

A circular economy requires that old concrete be 100% recycled so that it can serve as a raw material for new concrete. The knowledge and developed techniques in which even cement can be recovered make an important contribution to this.

The optimal recycling of concrete makes the extraction of primary raw materials unnecessary. We are not that far yet but important steps have already been taken that allow us to significantly reduce CO2 emissions and the spatial effects of primary raw material extraction.

The production of cement, the main raw material of concrete, causes about 8% of global CO2 emissions. High-quality reuse of concrete helps reduce these CO2 emissions.

In short, recycling concrete is an important step toward sustainable construction practices. By reducing construction waste, the need for natural aggregates and CO2 emissions, concrete recycling helps protect the planet and make the construction industry more sustainable. It is a practice that should be encouraged and supported by builders, developers and governments
