Turkmen scientists have developed a new, more environmentally friendly cement production technology that reduces environmental impact without compromising the quality of construction materials, infotabigat.kz reports, citing Turkmenistaninfo.
The innovation was presented by researchers from the Institute of Chemistry of the Academy of Sciences of Turkmenistan. The technology focuses on producing Portland cement with a higher share of mineral additives, allowing manufacturers to reduce the volume of clinker — the most energy-intensive stage of cement production and a major source of greenhouse gas emissions.
According to Dr. Rejepnur Nurberdiyev, Head of the Industrial Chemistry Laboratory and Doctor of Technical Sciences, the researchers propose increasing the proportion of active mineral components in cement from 20 percent to 35 percent. This approach significantly reduces fuel and natural gas consumption.
The mineral additive used in the new formulation is locally sourced opoka, a material rich in reactive silicon oxide. Studies show that cement produced with this composition maintains its strength and resistance to aggressive environments while substantially lowering emissions and resource use. Clinker savings exceed 300 kilograms per ton of cement.
The research findings have been published in an international scientific journal and confirmed through joint studies with the State Energy Institute of Turkmenistan.
Currently, five cement plants operate in the country with a combined annual capacity of more than 3.5 million tons. The adoption of the new technology could improve the energy efficiency of the industry and bring it closer to green economy standards.
