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.

Japan: Sumitomo Osaka Cement plans to set up a ‘Sustainability Promotion Office’ in April 2021 as part of the company’s efforts towards carbon neutrality by 2050. It follows the company’s medium and long-term sustainability targets that were set in December 2020.

Financial results for 2020 from the major Chinese cement companies are now out, making it time for a recap. Firstly, information from the China Cement Association (CCA) is worth looking at. The country had a cement production capacity of 1.83Bnt/yr in 2020. For an idea of the current pace of industry growth, 26 new integrated production lines were built in 2020 with a clinker production capacity of just under 40Mt/yr.

This is as one might expect from the world’s biggest cement market. However, the CCA also revealed that the country has over 3400 domestic cement companies, of which two thirds are independent cement grinding companies. Most of these were reportedly created during the late 2000s as dry kilns started to predominate. The CCA is concerned with the quality of the cement some of these companies produce and the lack of order in this part of the market such as regional imbalances. This suggests that the government’s attempts to consolidate the cement industry as a whole had led to the independent companies heading down the supply chain. It also raises the possibility that the government-led consolidation drive may move to grinding next. One news story to remember here is that in February 2021 the CCA called for its industry to respect competition laws following a government investigation. Later in the month it emerged that eight cement companies in Shandong Province had been fined US$35m for price fixing in a sophisticated cartel whereby the perpetrators went as far arranging a formal price management committee to regulate the market.

The CCA described 2020 as a year of sudden decline, rapid recovery and stability. Coronavirus hit cement output in the first quarter of 2020 leading to unprecedented monthly year-on-year declines before it bounced right back in a classic ‘V’ shaped recovery pattern. Despite the pandemic and bad weather later in the year, annual output rose by 2% year-on-year to 2.37Bnt in 2020 from 2.32Bnt in 2019. This has carried on into 2021 with a 61% increase in January and February 2021 to 241Mt from 150Mt in the same period in 2020. That’s not surprising given that China was suffering from the pandemic in these months in 2020 but the growth also suggests that the industry may have gone past stability and is growing beyond simply compensating for lost ground.

Chart 2 above shows cement production in 2020 from a provincial perspective. Note the sharp decline, more than 10% year-on-year, in Hubei Province (shown in dark green). Its capital Wuhan is where the first documented outbreak of coronavirus took place followed by a severe lockdown. Zooming further out, China’s clinker imports grew by 47% year-on-year to 33.4Mt in 2020. This is the third consecutive year of import growth, according to the CCA. The leading sources were Vietnam (59%), Indonesia (10%), Thailand (10%) and Japan (8%). China has become the main export destination for South East Asian cement producers and Chinese imports are expected to continue growing in 2021.

Moving to the financial figures from the larger Chinese cement producers, CNBM and Anhui Conch remain the world’s two largest cement producing companies by revenue, beating multinational peers such as CRH, LafargeHolcim and HeidelbergCement. Anhui Conch appeared to be one of the winners in 2020 and Huaxin Cement appeared to be one of the losers. This is misleading from a cement perspective because Anhui Conch’s increased revenue actually arose from its businesses selling materials other than clinker and cement products. Its cement sales and cement trading revenue remained stable. On the other hand, Huaxin Cement was based, as it describes, in the epicentre of the epidemic and it then had to contend with flooding along the Yangtze River later in the year. Under these conditions, it is unsurprising that its revenue fell.

CNBM’s cement sales revenue fell by 3% year-on-year to US$19.5bn in 2020 with sales from its new materials and engineering compensating. Anhui Conch noted falling product prices in 2020 to varying degrees in most of the different regions of China except for the south. CNBM broadly agreed with this assessment in its financial results. Anhui Conch also reported that its export sales volumes and revenue fell by 51% and 45% year-on-year respectively due to the effects of coronavirus in overseas markets. The last point is interesting given that China increasingly appears in lists of major cement and clinker exporters to different countries. This seems to be more through the sheer size of the domestic sector rather than any concerted efforts at targeting exports.

One major story on CNBM over the last 15 months has been its drive to further consolidate its subsidiaries. In early March 2021 it said it was intending to increase its stake in Tianshan Cement to 88% from 46% and other related transactions. This followed the announcement of restructuring plans in mid-2020 whereby subsidiary Tianshan Cement would take control of China United Cement, North Cement, Sinoma Cement, South Cement, Southwest Cement and CNBM Investment. The move was expected to significantly increase operational efficiency of its constituent cement companies as they would be able to start acting in a more coordinated manner and address ‘fundamental’ issues with production overcapacity nationally.

In summary, the Chinese cement market appears to have more than compensated for the shocks it faced in 2020 with growth in January and February 2021 surpassing the depression in early 2020. Market consolidation is continuing, notably with CNBM’s efforts to better control the world’s largest cement producing company. Alongside this the CCA may be starting to suggest that rationalisation efforts previously focused on integrated plants should perhaps be now looking at the more independent grinding sector. The government continues to tighten regulations on new production capacity and is in the process of introducing new rules increasing the ratio of old lines that have to be shut down before new ones can be built. Finally, China introduced its interim national emissions trading scheme in February 2021, which has large implications for the cement sector in the future, even if the current price lags well behind Europe at present.

Indonesia: Semen Indonesia has detailed its plans for future exports of cement to North America. The Investor Daily newspaper has reported that the producer and subsidiary Solusi Bangun Indonesia will target 0.5 – 1Mt of cement exports to North America in 2021, according to president director Hendi Santoso. The export plans will be carried out in partnership with Japan-based Taiheiyo Cement, which already has a US market presence and owns a 15% stake in Solusi Bangun Indonesia. Hendi said that the move aims to ‘cushion’ the decline in domestic cement sales, down by 28% bulk and 13% bagged year-on-year in 2020. The company successfully exported cement to Australia, Bangladesh, China, Fiji and Sri Lanka in 2020.

President commissioner Rudi Antara said, "The Covid-19 outbreak still colours our lives. There is no other choice but to increase business efficiency and the top line outside of our main markets."

Japan: Taiheiyo Cement plans to set up a Carbon Neutral Technology Development Project Team in April 2021. The team will develop and apply carbon capture and storage (CCS) technologies for installation at the producer’s cement kilns. The company said that the team seeks to develop cost-practical product for industrial application. Following on from this, it plans to develop CCS technologies which make use of other cement plant processes, and which integrates the circular economic use of industrial by-products. Carbon neutrality is the ultimate aim.

The group said, “By establishing a new project team that is a cross-company organisation, we will gather our wisdom and realise carbon neutrality. We will strongly promote the development of innovative technologies for this purpose.”

Philippines: Japan-based Taiheiyo Cement subsidiary Taiheiyo Cement Philippines has announced the formation of the Philippines Renewal Construction Project team. The company says that the team will support work on a new production line at the company’s integrated San Fernando cement plant in Cebu. When finished, the upgrade will give the company a total production capacity of 3Mt/yr. The producer said that expanding production capacity in the country is among its biggest growth strategies. Its longer-term sales target is 5Mt/yr, corresponding to a domestic sales share of 10%.

The company anticipates a growth in cement demand in 2021, in part due to the government’s infrastructure budget of US$20.8bn, over 5% of gross domestic product.
