US: The Japan Coal Energy Center (JCOAL), GreenOre Clean Tech, Columbia University and Wyoming Infrastructure Authority (WIA) have entered into a memorandum of understanding (MOU) to test carbon utilisation and recycling technology. GreenOre Clean Tech, using technology under license from Columbia University, will use testing space at the Integrated Test Center (ITC) near the Dry Fork Station coal-fired power station in Gillette, Wyoming. Calcium carbonate produced through CO₂ mineralisation could then potentially be used for aggregates, concrete production or in paper production. The test will be funded by JCOAL with additional support from project partners.

The State of Wyoming and JCOAL have been working together since 2016, when they signed an initial MOU committing to cooperation in coal research and development of technologies and coal trade. JCOAL operates under the supervision of the Ministry of Economy, Trade and Industry of Japan and is supported by more than 120 member coal-related businesses, including Kawasaki Heavy Industries, Mitsubishi Hitachi Power Systems, Nippon Steel and Toshiba. Kawasaki is scheduled to test its solid sorbent capture technology at the ITC beginning in 2021.

Azerbaijan: Data from the State Statistics Committee shows that cement production in Azerbaijan dropped by 5.2% year-on-year to 1.6Mt in the first half of 2019. This has been blamed on a poor market, according to the Turan Information Agency. Despite this, concrete mix sales increased by 20.5% to 0.78Mt.

UK: Climate change protestors from the Extinction Rebellion group have been arrested for blockading a ready-mixed concrete plant operated by London Concrete at Bow in London. Concrete from the plant is being used to supply a major road tunnel project at Silvertown beneath the River Thames, according to Reuters. Extinction Rebellion blamed concrete production for being a major source of CO2 emissions and it also has concerns about dust pollution. Seven people were arrested by the Metropolitan Police for aggravated trespass. London Concrete is part of LafargeHolcim Group. It operates 12 concrete plants in London.

Netherlands: Holcim Nederland Bouwmaterialen has recevied certification from the Concrete Sustainability Council (CSC) for its five concrete plants. The certification process was handled by Kiwa Netherlands.

Romania: LafargeHolcim has signed an agreement with Oresa to buy Somaco, precast concrete producers. The transaction will allow LafargeHolcim to develop its position on the Romanian building materials market, where the company is already present in the cement, ready-mix concrete and aggregates segments. No value for the transaction has been disclosed. It is subject to regulatory approvals and is expected to close in late 2019.

“This is our sixth bolt-on acquisition this year and we are delivering on our commitment to further develop our Solutions & Products business segment as part of Strategy 2022 – ‘Building for Growth.’ The acquisition enables LafargeHolcim to enter Romania’s fast growing precast concrete market and to become an integrated solutions provider for our local customers,” said Jan Jenisch, chief executive officer (CEO) of LafargeHolcim.

Somaco operates five precast concrete plants and one plant for aerated blocks in Romania. The company reported net sales of Euro56m in 2018 and has 750 employees. It has a portfolio of precast products for bridges, tunnels, subways and logistics platforms and supplies products for the residential sector.

France: Lafarge France has launched its Lafarge 360 initiative. The scheme aims to aid specifiers, contractors and builders make low-carbon structures through reducing CO₂ emissions, preserving natural resources and responsible innovation. It will start the initiative by proving a Lafarge 360 score on its associated digital platform to allow customers to assess the environmental impact of Lafarge’s products. By providing a rating of A to D the tool will offer information on the concrete types.

US: Hawaii’s Department of Transportation plans to use carbon-injected concrete for its new projects. This will include a new structure to protect a highway tunnel from rockfalls, according to Reuters. The Department of Transportation was testing CO₂-injected concrete on an access road project with CarbonCure Technologies in May 2019. The latest decision follows a resolution by state legislators that city administrators ‘consider’ using CO₂-injected concrete in city and county infrastructure where concrete is used.

In late June 2019 CarbonCure announced that its had formed a partnership with HC&D Ready Mix, a local concrete producer, to use its CO₂-injected concrete process. It is the second deal with a concrete producer in the state that CarbonCure has arranged.

India: Ambuja Cement is looking for ready-mix concrete (RMX) and aggregate assets to buy as part of its growth plans. A company source quoted by the Business Standard newspaper said that it was considering ‘growth options’ in all of its core businesses of cement, RMX and aggregates. Industry analysts have interpreted this as an effort to diversify the business away from dominance by the cement sector. However, expansion in the RMX market is expected to be difficult owing to the lack of local organisation in the market.

The subsidiary of LafargeHolcim has a cement production capacity of 63Mt/yr, including those of ACC. Both Ambuja Cement and ACC use a master supply agreement to coordinate sales, marketing and logistics.

Italy: Buzzi Unicem says that its Unical subsidiary is the first national concrete producer to earn silver level RSS certification from the Concrete Sustainability Council. The accreditation asserts that a company meets criteria for sustainable practices and operates in a sustainable, environmentally positive manner. Unical’s Strada Berlia concrete batching plant in Turin received the certification in June 2019. The CSC procedure also included certifying the cement produced by Buzzi Unicem’s Robilante Cement plant and the aggregates from Ceretto quarry. The certificate was issued by ICMQ, the Italian Certification Body member of CSC. Unical manages more than 100 concrete plants in Italy.

France: Hoffmann Green Cement Technologies and Bouygues Construction have signed a 30-month initial technical and commercial collaboration agreement to develop and test concrete formulations using new cement made from Hoffmann’s H-EVA technology. Hoffmann Green Cement inaugurated its pilot plant at Bournezeau, Vendée in late 2018. The unit will manufacture cement products using flash-calcined metakaolin and blast-furnace slag. Bouygues Construction is a global construction company with a presence in over 60 countries.
