Holcim invests in Coomtech10 May 2023, Published under Cement NewsHolcim invests in Coomtech, a cleantech start-up that offers an innovative low-emission kinetic drying technology for raw materials. Coomtech's technology combines low-carbon and circular benefits to emits up to 75 per cent less CO 2 than traditional drying methods, enabling the use of recycled materials in cement and concrete that would otherwise require a high amount of energy to dry. The investment builds on Holcim and Coomtech’s current collaboration to develop a new low-carbon cement... |
Dalmia Cement and Vedanta Aluminium team up to produce low-carbon cement16 March 2023, Published under Cement NewsVedanta Aluminium has entered into a long-term partnership with Dalmia Cement (Bharat) for the supply of industrial wastes such as fly ash and spent pot lining (SPL) to produce low-carbon cement. Under the agreement, Vedanta’s large aluminium smelter at Jharsuguda will transport around 20 rakes of fly ash per month for five years to Dalmia’s cement plants in Odisha, Chhattisgarh, Meghalaya and Assam, as well as supply SPL to Dalmia’s Rajgangpur plant in Odisha for three years.

Can alternative raw material usage be better implemented?27 January 2023, Published under Cement NewsCEMBUREAU's recent webinar on '2050 ambitions and the role of secondary materials in the European cement sector' indicated how challenging it will be to meet the CEMBUREAU 2050 Carbon Neutrality Map decarbonising targets through an increased uptake of alternative raw materials (ARMs). While Europe has clear sustainable and net zero ambitions, enshrined in its Green Deal legislation, obtaining these goals has several barriers regarding the availability of materials, political challenges or so... |
CEMEX sets "most ambitious" decarbonisation goals in the industry17 November 2022, Published under Cement NewsCEMEX has a “promising medium term outlook”, according to Fernando A González, chief executive officer. Speaking at the company’s 2022 CEMEX Day on 16 November, Mr González said the markets in which the company operates are seeing strong demographics and urbanisation trends, along with “pressing needs for more resilient and sustainable infrastructure, buildings and homes”.

New material research aims to reduce the environmental impact of cement and steel industries22 December 2021, Published under Cement NewsResearchers from the Department of Materials Science and Engineering at the University of Sheffield are developing processes and technologies for the sustainable manufacture of cement, by incorporating iron-rich by-products from the steel industry. The research programme, which starts in June 2022, will be known as 'FeRICH: developing iron-rich cement for the valorisation and upcycling of steel slags'. It will look at ways to upcycle the by-products of the steel industry, leading to the pr... |
Spain’s cement sector recovers 57Mt of waste in 15 years26 November 2021, Published under Cement NewsThe Spanish cement industry has recovered 57Mt of waste from 88 sectors between 2004-19, reports the Fundación CEMA in collaboration with Institut Cerdà. This has prevented the release of 1Mt of CO2 emissions to the atmosphere and savings of EUR115m by not sending the waste to landfills. The report confirms that the optimisation of synergies has resulted in the cement sector becoming one of the largest recyclers of mineral waste in Spain and a leader in energy recovery. It has injected alm... |
