The construction industry is increasingly adopting a circular economy approach on a global scale, prioritising energy efficiency, alternative fuels, and sustainable raw materials. The production of industrial sand and the separation of usable construction materials for cement and concrete production present significant business opportunities while addressing the rising demand for sustainable practices.
The Metso HRC 8 high-pressure grinding rolls (HPGR) crusher not only supports sustainable operations but also offers process flexibility, higher capacity, and low energy and wear part consumption, making it an attractive option for aggregate producers and contractors.
Metso is showcasing its HRC 8 crusher at BAUMA 2025 international construction machinery trade fair taking place April 7-13, 2025, in Munich, Germany. Metso booth #203 is in Hall B2.
With declining sand extraction sites in Europe and reduced permitting for new ones, the supply situation is challenging, and transporting sand from distant locations is often not economically viable. The cement industry creates 8% of global CO2 emissions. The target is to reduce these emissions by 25-55% by 2030 and achieve zero-emission cement production by 2050. Currently, up to 20-30% of recycled materials are used in cement and concrete production.
“The construction industry is moving towards circular economy, and urbanization is expected to drive demand for raw materials to meet the growing global needs. Metso’s HRC 8 offers a proven solution for aggregate producers and contractors, delivering high-quality output with excellent gradation and particle shape. It fully meets the specifications for recycled concrete and cement applications. With over 160 units currently sold worldwide, the HRC 8 has received consistently positive feedback from customers, supporting sustainable and efficient production,” says Oldemar Meneses, Product Manager Impactors and Sand solutions, Aggregates at Metso.
Metso HRC 8 for Aggregates is available as a stationary crusher or as a part of Nordplant’s pre-designed crushing modules and plants. As a portable model on Nordwheeler, the crusher provides flexibility for relocation based on material location. Due to its energy efficiency, it is included in the Metso Plus offering.
The HRC 8 crusher generates very low dust emissions and noise levels, saves up to 50% energy compared to other technologies, and can convert quarry waste and demolition waste (upcycle Construction and Demolition Waste CDW) into high-quality, high-value sellable products. It can release recycled cement from CDW, produce high-quality manufactured sand, and improve poor-quality sand, thereby avoiding the use of virgin resources and upcycling quarry waste materials.
