Indonesia: Suvo Strategic Minerals has reported successful laboratory tests in collaboration with Makassar State University (UNM) in Indonesia, transforming nickel slag into a ‘high-strength, low-cost and low-carbon’ cement, according to The Sydney Morning Herald. The trials used slag from PT Huadi Nickel-Alloy Indonesia's operations in South Sulawesi, achieving a compressive strength of 37.5MPa after seven days. The company is now looking to conduct further testing and will provide the results to PT Huadi, with the aim of forming a partnership for the commercialisation of low-carbon cement using nickel slag.

Aaron Bank, executive chair of Suvo Strategic Minerals, said “We are excited to have commenced this workstream in Indonesia testing the byproduct of one of the country’s largest mining companies, with our ultimate goal being to manufacture an environmentally-friendly and low-carbon alternative to Portland cement. Achieving up to 37.5MPa after only seven days is an outstanding first round trial result for the company and could provide an entry into a large industry.”

Greece: ThyyssenKrupp Polysius has signed a front-end engineering design contract with Titan Group for the Ifestos carbon capture project at Titan’s Kamari cement plant. The project will equip the plant’s two kilns with oxyfuel systems to reduce CO₂ emissions by 1.9Mt/yr, ‘almost completely’, said ThyssenKrupp. The captured CO₂ is then liquefied and transported to a permanent storage site in the Mediterranean region. Full operation is expected by the end of 2029.

Cetin Nazikkol, chief strategy officer at ThyssenKrupp Decarbon Technologies, said “With the oxyfuel technology we have developed, around 1.9Mt/yr of CO₂ can be captured at the Kamari plant alone. This corresponds to around 12% of greenhouse gas emissions from all Greek industries. We are thus making a significant contribution to one of the largest CO₂ capture projects in Europe.”

Christian Myland, CEO of ThyssenKrupp Polysius, said “For our customer Titan Group, we will be using the latest CO₂ separation technology. We will design and equip the first kiln line with the proven oxyfuel technology. When modernising the second kiln line, the latest generation of this technology will be used with the pure oxyfuel system. Overall, this will enable us to capture almost 100% of CO₂ emissions.”

Vietnam: According to data from the General Statistics Office, Vietnam produced 134.5Mt of cement in the first nine months of 2024, marking a 2% rise year-on-year. In September 2024, the country's cement output reached 15.3Mt, up by 9% compared to September 2023.

Saudi Arabia: In 2023, Saudi cement and clinker exports exceeded 8.48Mt. According to Al Riyadh news, the country ranks 10th globally with a production capacity of over 80Mt/yr from 20 plants. Local demand for cement reached 47.3Mt in 2023, with construction sector spending expected to hit US$1.6tn by 2030.

Minister of industry and mineral resources Bandar Alkhorayef said "The cement sector in the Kingdom has a promising future, with several leading companies constantly adopting the latest manufacturing technologies, helping to improve production efficiency. Recently, some companies have been active in upgrading and replacing some of their production lines to enhance quality."
