Europe: Cembureau, the European cement association, has calculated that if the European Union (UN) emissions trading scheme (ETS) CO₂ cost reaches Euro90/t then this could represent 12 - 15% of the production costs of cement producers. The association made its calculation for an average cement plant in the region using data from Ecorys, WIFO, the National Institute of Economic and Social Research for the EU Commission and Agora Energiewende.

Cembureau has called for the EU government to delay its proposed ETS free allocation phase-out and to bring forward the implementation of its proposed carbon border adjustment mechanism (CBAM) from 2026. It has called on policy makers to ‘use all the tools available to stabilise market prices, support energy intensive industries through state aid and examine the functioning of the European gas and electricity markets, as well as the EU ETS.’

Europe: Cembureau has announced the launch of its Map of Innovation Projects interactive map. The feature maps past and current sustainability-enhancing projects at European cement plants. It currently displays a total of 53 different projects. It is available here.

Thailand: Siam Cement Group (SCG) plans to spend US$2bn towards meeting its CO₂ reduction target by 2030. The industrial group and cement producer intends to reduce its emissions by 20% by the end of the decade, according to the Bangkok Post newspaper. Chief executive officer Roongrote Rangsiyopash, said that the investment will be made from 2022 to 2030 and that it follows the United Nation’s Sustainable Development Goals (SDG), the Thai government's bio, circular and green (BCG) economic model and environmental, social and governance standards (ESG). After 2030 the group has a net zero goal for 2050.

In cement production the SCG wants to increase its rate of alternative fuels such as biomass and refuse-derived fuel. It also wants to invest in carbon capture utilisation and storage, use electric vehicles and use artificial intelligence systems in energy management. The group plans to reduce coal usage at its cement plants in Thailand, Vietnam, Laos, Cambodia and Indonesia by 50% in 2022. It also plans to use more electricity generated by renewable energy for its factories.

Japan: Taiheiyo Cement is among 13 participant companies whose proposed carbon capture, utilisation and storage (CCUS) demonstration hub has received approval to proceed with funding from the Japan Ministry of the Environment. Nikkei Business Trends News has reported that Toshiba Energy Systems and Solutions, Uyeno Transtech, JGC, Chiyoda, Taisei Corporation, the University of Tokyo, Kyushu University, Japan NUS, the National Institute of Advanced Industrial Science and Technology and QJ Science also collaborated in the development of the CCUS system. The trial will begin in early 2022 and conclude in the 2025 financial year.

India: ACC has expanded its Green Building Centre chain into Telangana. The Orissa Diary newspaper has reported that the producer inaugurated the new Karimnagar Green Building Centre in the state on 14 December 2021. The centre will stock affordable alternative building products such as fly ash bricks and reduced-CO² concrete blocks. ACC aims to support Indian cities’ social, environmental and financial development through its Green Building Centres.

Managing director and chief executive officer Sridhar Balakrishnan said "At ACC, we strongly believe in embracing communities and working together to effect the real change. ACC's Green Building Centre business model benefits thousands of small scale construction workers by giving them employment and training."

Italy: Cementir Holding has been achieved its first CDP A- rating for climate change mitigation in its operations. The producer said that the global average rating is B-, compared to B in Europe and in the cement and concrete industry globally. CDP awarded Cementir a B for water security, its first such rating in the category.

Chair and chief executive officer Francesco Caltagirone said “This achievement is a further recognition of our efforts to make our carbon footprint more sustainable. We are committed to tackling climate change and minimising our environmental impact.”

Mexico/UK: Cemex has partnered with UK-based carbon capture equipment supplier Carbon8 Systems to evaluate possible uses of the supplier’s Accelerated Carbonation Technology (ACT) in the group’s cement production. Operators can use the equipment to produce carbon-infused sustainable materials from thermal residues. Cemex says that one possible application will be in the production of supplementary cementitious materials. Under the partnership, Carbon8 Systems will evaluate a range of Cemex’s byproducts for possible use, beginning at its Rüdersdorf cement plant in Germany and Rugby cement plant in the UK. It will also evaluate the suitability of alternative lightweight aggregates produced using ACT for sale in each market.

Executive vice president sustainability, commercial, and operations development Juan Romero said "This initiative with Carbon8 Systems is another example of the work we are doing with partners across industries, academia, and startups to tap into the latest innovation and disruptive technologies to achieve our ambition of delivering net-zero CO2 concrete globally to all of our customers."

France: Germany-based ThyssenKrupp has won a contract for the installation of a new 4000t/day clinker line at Ciments Calcia’s Airvault cement plant in Poitou-Charentes. The supplier expects the new line to double the plant’s clinker capacity while also reducing its CO2 emissions. It is intended to replace the two existing lines at the site.

ThyssenKrupp will supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 type vertical roller mill and a 10,000t tangential blending silo to process raw materials for the line. A single-string, five-stage Dopol type cyclone preheater with integral calciner will be supplied that is suitable to use with alternative fuels, with the possibility of conversion to oxyfuel in future. ThyssenKrupp plans to preassemble the preheater, reducing anticipated construction time ‘by several months.’ The plant also includes a Polytrack clinker cooler, a solid recovered fuel (SRF) preparation line and dedusting systems. Commissioning is scheduled for mid-2024.

No value for the project has been disclosed by Ciments Calcia or ThyssenKrupp. However, Ciments Calcia previously announced a proposed investment of Euro300m in January 2021.

Belgium: Environmental disclosure organisation CDP has listed Cemex, HeidelbergCement and Holcim among 200 companies on its 2021 Climate Change A List for actions to mitigate their CO2 emissions. Holcim’s Indian subsidiaries ACC and Ambuja Cements also received A ratings. Both ACC and Ambuja appeared on CDP’s 2021 Water Security A List, while Holcim scored an A-.

Chief executive officer Jan Jenisch said “Building on the launch of our nature-positive strategy this year, we set new and ambitious goals to achieve water security across our operations worldwide, with our colleagues from Ambuja in India leading the way. CDP’s rankings this year are a testimony to the tremendous work carried out by our 70,000 people around the world and a great encouragement for all of us to keep raising the bar.”

India: Dalmia Cement plans to invest US$75.2m in a 2.6Mt/yr expansion to its Bokaro grinding plant in Jharkhand. The company says that the work will increase the plant’s capacity by 70% to 6.3Mt/yr from 3.7Mt/yr. US$33.2m will go towards the installation of new solar power plant. The company will also set up a waste management facility at the site, using US$1.06m of the investment.

Managing director Puneet Dalmia said “As we are further investing in the Eastern India market to participate in its economic growth story, we are also taking our corporate responsibility seriously by placing the utmost importance on environmental protection and social impact. We are confident that the employment generated through our investments and the skill enhancement in our social initiatives will help create a progressive ecosystem where we help people become independent and self-sufficient. We are excited and look forward to partnering with the state to achieve our business, social and sustainability goals.”
