Betolar’s advanced metal separation technology enables the purification of industrial slag and mine tailings to create a valuable raw material for the production of green cement.
Based on recent test data, the 28-day compressive strength of its green cement fully matches the performance of traditional portland cement and clearly exceeds the strength of binder made from blast furnace slag, according to the manufacturer. Its high reactivity and excellent activity index make it a competitive alternative for various construction and mining applications.
“Betolar’s green cement not only matches the performance of traditional portland cement but also offers significant environmental and cost benefits. This is an important step towards more sustainable construction and value creation based on the circular economy,” said the Betolar President and CEO Tuija Kalpala. “Our metal extraction technology enables both the efficient recovery of valuable metals and the production of low-carbon green cement from the same material stream. This is a significant breakthrough in the comprehensive utilization of industrial sidestreams and mine tailings.”
The production of green cement is based on the utilization of industrial sidestreams, which reduces the use of virgin raw materials and significantly lowers the carbon dioxide emissions of the manufacturing process. At the same time, it helps reduce the environmental load of waste areas – such as land use, dusting and leakage into nature.
Betolar said the market potential is significant. For example, the annual amount of unutilized slag from the steel industry alone, approximately 500 million tons in the world, would cover about 10% of the world’s cement needs when processed using Betolar’s method.
The construction industry is now actively seeking low-carbon solutions, and the demand for low-emission raw materials such as green cement is expected to grow strongly in the coming years. Depending on the source, the estimated average annual growth rate is 20% to 30% toward 2030, which would mean a multiplication of various applications of Betolar’s material technology by the end of the decade.
