Brazil: Norway-based Norsk Hydro and the Federal University of Para (UFPA) have announced their collaboration on the development of a low-carbon cement from bauxite residue from Norsk Hydro subsidiary Alunorte’s bauxite mining and alumina refining operations in the state of Pará. Electronic News has reported that the research partnership hopes to develop a new cement for commercial production and sale by 2030. This will use an estimated 500,000t/yr of waste bauxite residue.

Norsk Hydro bauxite and alumina research and development senior manager Erik Araujo said, “Hydro seeks to be a benchmark in sustainability in the aluminium industry. The research is an opportunity to promote intersectional advances in our environmental management, with a reduction in carbon emissions for the cement industry.

Mozambique: Dugong Cimentos says that construction of its new 1.8Mt/yr integrated cement plant in Matutuíne District, Maputo Province, is 90% complete. The Noticias newspaper has reported that the plant cost US$330m and was paid for by private Chinese investors. It will permanently employ 500 people, including 400 Mozambicans, when operational. The plant will consume 400,000t/yr of coal and produce cement as well as clinker for grinding at other Mozambique plants that currently import it.

Germany: HeidelbergCement has reported the successful resurfacing of a section of Federal Motorway 5 (BAB 5) between Karlsruhe and Frankfurt using a concrete made from low-alkali cement produced at its 1.4Mt/yr-capacity Schelklingen, Baden-Württemberg integrated cement plant. The company used over 3600t of cement to produce the 12,000m³ of concrete required for the 3.2km stretch of road. Traffic infrastructure product manager Klaus Felsch said, “The cement’s low alkali content significantly reduces the risk of an alkali-silica reaction and maximizes the durability of the concrete.”

India: The Cement Manufacturers Association (CMA) has contacted the Department for the Promotion of Industry and Internal Trade to urge its reconsideration of an expected decision that the CMA says will disrupt the mining sector, upon which eight key industries including cement depend. Indo-Asian News Service has reported that the government department may be considering the deletion of a provision of the Mines and Minerals Development and Regulation (Amendment) Act that gives a captive lease to reconnaissance permit (RP) and prospecting licence (PL) holders to begin mining for minerals discovered in the licenced area. The CMA has argued that introducing any additional stage between explorations and extraction “would not go well with the spirit of ‘ease of doing business.’” It added, “The industry would like development policies to be predictable and consistent to usher in fresh investments as well as to protect the efforts and hardships that go into establishing an industrial setup.”
