Japan: Taiheiyo Cement says that the cost of producing its cement has increased throughout 2021. The company said the coal prices have risen due to increased coal demand in China and a reduction in exports from coal-producing countries. It anticipates further rises in the price of coal. Additionally, it foresees a rise in maintenance costs as the equipment at its plants nears the end of its service life. The producer says that it is endeavouring to improve productivity and reduce costs.

Japan: Sumitomo Osaka Cement subsidiary Hachinohe Cement has announced that it will be receiving heavy oil and woodchips from cargo washed ashore from the wreck of a ship at Hachinohe port on 11 August 2021. The company plans to use the waste as refuse-derived fuel (RDF) for cement production at its cement Hachinohe cement plant. The company said that the oil spill from the incident has had a great impact on the region. It added “In the future, we would like to actively promote the acceptance of wreckage with heavy oil attached and cooperate in the early resolution of the situation.”

Japan: Sumitomo Osaka Cement has joined the Task Force on Climate-Related Financial Decisions (TCFD) Consortium. The consortium is committed to facilitating effective and efficient disclosure of climate-related corporate information and their use by financial institutions. As a member, Sumitomo Osaka Cement will conduct scenario analysis on the climate change impacts of all its businesses. This includes its cement business, which the company says accounts for the majority of its CO₂ emissions.

Australia: Sumitomo Osaka Cement has started operating a cement terminal at Port Kembla in New South Wales. The Japan-based cement producer owns a 30% share in the company running the unit, which operates as Falcon CP. The terminal has a silo capacity of 36,000t. Sumitomo Osaka Cement says it plans to use the terminal as a means to increase its activity in the local market. It runs its regional headquarters in Sydney trading as SOC Oceania.

Japan: Mitsubishi Materials and Ube Industries plan to merge their respective cement businesses and related businesses on 1 April 2022. The new successor company will be temporarily known as C Integration Arrangement before officially becoming known as Mitsubishi UBE Cement Corporation. However, the new name will be subject to input by shareholders.

The two cement producers first announced discussions in early 2020 about a potential merger of their cement businesses and related concerns. They decided to explore merging their cement operations following slowing demand and increased costs due to higher energy prices. They have worked together since 1998 in a joint venture called Ube-Mitsubishi Cement, which integrated their cement sales and logistics operations.

South Korea: Hanil Hyundai Cement has placed an order with Japan-based Kawasaki Heavy Industries for the design and installation of a 22.6MW waste heat recovery (WHR) unit at its Yeongwol cement plant in Gangwon. The WHR plant will generate power from heat from two of the plant’s production lines when commissioned in December 2022. The supplier says that it will serve 30% of the plant’s energy needs. Kawasaki Heavy Industries says it has previously supplied WHR units to Japan, Germany, South Korea, Turkey, China, Vietnam, India, Pakistan and elsewhere.

Japan: Taiheiyo Cement recorded full-year consolidated net sales of US$7.89bn in its 2021 financial year to 31 March 2021, down by 2% year-on-year from US$8.07bn in the 2020 financial year. The group’s net profit rose by 20% to US$427m from US$357m. Domestic cement sales volumes fell by 4.8% to 13.8Mt and exports sales dropped by 2.2% to 3.8Mt. The cement producer attributed this to falling local demand for cement since June 2020 due to the suspension of construction work in response to the coronavirus pandemic. It also noted a shortage of construction workers.

Japan: An off-grid power system at Taiheiyo Cement’s Hidaka cement plant in Saitama prefecture exploded overnight on 27 April 2021, damaging a car in a nearby car park. Fire services quickly fought and extinguished a fire in woodland surrounding the plant. Kyodo News has reported that none of the 14 people working at the site at the time was harmed. Residents 2km away reportedly heard and felt the blast.

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.
