France: LafargeHolcim France, part of Switzerland-based LafargeHolcim, plans to invest Euro6.2m in 2021 in upgrading its integrated La Malle cement plant in Bouc-Bel-Air, Bouches-du-Rhône department. The La Provence newspaper has reported that the plans include a Euro4.5m modernisation of the flue gas desulphurisation system of the plant’s Line 2 using equipment ordered from Italy-based Boldrocchi. The company said that it plans to maintain similar investment levels in the plant in 2022 and 2023.

The plant had reportedly received complaints about sulphurous smells in the local area. The producer attributed this to the high sulphur content in its clay, which is sometimes over 70%. It said that it is altering supply arrangement to include clay from its L'Estaque, Bouc-Bel-Air and Bellegarde, Ain quarries in its clinker mix in order to reduce sulphur content by 20%.

France: A fire has been reported at LafargeHolcim France’s integrated Saint-Pierre-la-Cour plant. It appears to have been caused by a fuel supply line explosion attached to the plant’s kiln, according to the Ouest France newspaper. No casualties have been reported by local fire fighters. The single kiln 1.5Mt/yr plant is the company’s largest in the country.

Japan: Taiheiyo Cement plans to start a CO₂ capture demonstration project at its Kumagaya plant in Kumagaya City, Saitama. It will use technology for CO₂ chemical absorption supplied by UK-based Carbon Clean, which has been awarded by Japan-based Marubeni Protechs in Japan. The project will have a capacity of 10t/day and demonstration tests will begin in September 2021. Taiheiyo Cement says that it believes that CO₂ recovery technology from cement kiln flue gas will require compact equipment that could be installed in cement plants and that suitable amine solvents for cement kiln flue gas are essential conditions. Its ultimate goal is to establish a technology that can be used to help it reach carbon neutrality by 2050.

The cement producer has been developing this technology as a sole grant recipient of the ‘Development of Carbon Circulation Technology for the Cement Industry,’ a project funded by the New Energy and Industrial Technology Development Organization (NEDO) which was awarded in June 2020. It also launched its internal Carbon Neutral Technology Development Project Team in April 2020, which has led on the project.

Marubeni Protechs, a wholly owned subsidiary of Marubeni Corporation, which invested in Carbon Clean, have been involved in a variety of domestic and international projects involving equipment supply and construction. The project at the Kumagaya plant is expected to be the first CO₂ capture plant that Marubeni Protechs and Carbon Clean have introduced in Japan. Marubeni Protechs and Carbon Clean intend to jointly introduce CO₂ capture plants in the future.

Japan: Researchers from the University of Tokyo have developed a new method for producing cement-free concrete from sand. The method reacts sand with alcohol in the presence of a catalyst, according to ChemEurope. When dehydrated, this produces tetraalkoxysilate. The research team then reintroduced water, and thus allowed the reactants to move back and forth between tetraalkoxysilate and sand. In this way, the sand particles progressively bonded together. The resulting concrete is reportedly more resilient to chemical, temperature and humidity changes than concrete produced from Ordinary Portland Cement (OPC).

In the report of the findings, researcher Ahmad Farahani wrote that various sources of sand tested suitable for use, including silica sand, glass beads and simulated moon sand. This gives the method the advantage that it is non-specific to raw materials or locations, and can be integrated into waste management.

UK: The Global Cement and Concrete Association (GCCA) has expanded its Innovandi innovation programme with the addition of a new Open Challenge innovation accelerator programme. The Open Challenge programme will bring together start-ups and leading cement and concrete producers to innovate for CO₂ emissions reduction in the cement industry. Its aim is carbon neutral concrete production by 2050.

GCCA chief executive officer Dinah McLeod said “The GCCA is delighted to be expanding Innovandi to encompass both the Research Network and the upcoming Open Challenge. By connecting innovative start-ups with cement and concrete producers we can help accelerate the development of solutions that address the emissions reduction challenges our industry faces.”
