US$100m investment in new cement plant near Juba 03 May 2024
South Sudan: B Smart, an investment company owned by son of a former Malaysian Prime Minister, plans to invest US$100m in constructing a cement plant near the capital city of Juba. The plant is targeted to be operational within 24 months pending necessary approvals, and will use limestone from Kapoeta, 275km east of Juba.
Deputy Secretary for Commerce and Industry, Kuol Daniel Ayulo, said "The plant will reduce the country's reliance on costly cement imports and accelerate infrastructure development."
UK: Seratech has developed a process using olivine, a mineral abundant in Earth's mantle, to produce ‘carbon-negative’ cement. The company's method involves replacing some of the clinker with silica extracted from olivine. Magnesium sulphate derived from the olivine reacts with CO₂ to form nesquehonite, a mineral that sequesters CO₂. This method uses CO₂ captured from emissions sources or directly from the air.
Sam Draper, CEO, explained the process: “The researchers extracted these compounds by dissolving powdered olivine in sulphuric acid. After separating the silica and magnesium sulphate, they bubbled CO₂ through the magnesium slurry to form nesquehonite.”
According to Draper, replacing 35% of regular cement with this silica would yield carbon-neutral results, while a 40% substitution could achieve carbon negativity. Current building standards allow up to 55% of cement to be replaced by this material, although robust testing has yet to be conducted.
Vietnam cement production falls 03 May 2024
Vietnam: Cement production in Vietnam has fallen by 0.7% year-on-year in the first four months of 2024, reaching 57.6Mt, according to the latest data from the government’s General Statistics Office. In April 2024, the country’s cement output was 16.8Mt, a year-on-year decline of 0.7%.
In 2023, the country produced 120.1Mt of cement, representing a year-on-year decrease of 4.5% from the previous year.
Malaysia: Heidelberg Materials has announced its acquisition of ACE Group, a supplier of pulverised fly ash, effective 1 May 2024. Reusing fly ash from energy generation contributes to reducing the CO₂ intensity of composite cement. When used as an additive, fly ash can replace part of the energy-intensive clinker and thus reduce the CO₂ intensity of the cement.
The acquisition includes ACE Greencemt Venture, ASAS Asia and AGP Logistics, with the leadership team from ACE Group continuing to manage the operations post-acquisition. Both parties have agreed not to disclose the financial terms of the transaction.
India: Nuvoco Vistas has announced its audited financial results for the year ended 31 March 2024. The producer recorded earnings before interest, depreciation and amortisation of US$199m, representing a year-on-year increase of 35%, and profit after tax of US$17.6m. Its net debt fell by US$46m year-on-year to US$482m. Cement sales volumes totalled 18.8Mt and revenue from operations reached US$1.3bn.
