Russia: Holcim Russia has committed to realising a 15% CO₂ emissions reduction in its cement production between 2019 and 2030 to 475kg/t from 561kg/t. It plans to further reduce its cement’s CO2 emissions to 453kg/t by 2050, and to implement further measures to ensure its net carbon neutrality at that time.

Corporate relations director Vitaly Bogachenko said “The company's goal is to drastically reduce carbon emissions, and there are two working solutions for this. The first is the use of alternative fuels (AF) obtained from different types of waste: residues of municipal solid waste after sorting and extraction of all useful fractions from them, used tyres and others. The presence of biomass in them makes such fuels carbon neutral, so emissions during production are significantly reduced. The second solution is to replace carbon intensive raw materials. For example, instead of limestone, we use slags. The 'recipe' for cement is completely different: thanks to the new composition and the lower temperature during the firing process, the carbon footprint in the production of cement is reduced.”

UK: The Mineral Products Association (MPA) has announced the successful completion of a trial of cement production using a net-zero fuel mix consisting of hydrogen and refuse-derived fuel (RDF) at Hanson’s Ribblesdale, Lancashire, cement plant. The RDF in the mix consists of meat and bone meal (MBM) from the food industry and glycerol from biodiesel production.

Increased alternative fuel (AF) substitution is one of seven key levers in the MPA’s Roadmap Beyond Net Zero emissions reduction strategy. The association says that the fuel will eliminate 180,000t/yr of CO₂ emissions from the Ribblesdale plant’s operations when fully implemented. The project received Euro3.71m in government funding.

Hanson’s environmental sustainability manager Iain Walpole said “We are delighted to be involved with this world-leading project, which is a further example of our commitment to cutting CO₂ emissions.” He added “It will also contribute to our ambition of supplying net zero carbon concrete by 2050.”

Poland: Lafarge Poland has laid the foundation stone for the Euro100m new kiln line at its Małogoszcz cement plant. The replacement of the three existing kilns and installation of an alternative fuel (AF) line aims to reduce the plant’s CO₂ emissions by 20% and its energy consumption by 33%. The company, a subsidiary of Switzerland-based Holcim, aims to make the cement plant into one of the European Union’s most modern. China National Building Material (CNBM) subsidiary Nanjing Kisen International Engineering will carry out the work, which is scheduled for completion in early 2023.

Project director Krzysztof Byczyński said “One of the three kilns has already been demolished and in its place a new kiln will be built with the necessary installations. Preparatory works for the construction of a new kiln are currently underway.”

Italy: The Italian cement association Federbeton has launched its comprehensive plan for cement industry decarbonisation in line with the EU’s European Green Deal target of a 55% reduction in CO₂ emissions between 1990 and 2030 and carbon neutrality by 2050. The strategy entails Euro4.2bn of total new investments andEuro1.4m/yr of extra operating costs across the industry. This will cover the adoption of transition technologies and the large-scale application of carbon capture and storage (CCS). The association says that while some such actions, such as alternative fuel (AF) substitution,are immediately available, others require further development. The sector’s primary fuel is petcoke, mainly imported from the Gulf of Mexico. As such, Federbeton has identified the 100% replacement of all fossil fuels with ‘low-carbon impact’ alternatives as a means of reducing the industry’s carbon footprint by 12% achievable in the short term. Renewable green hydrogen use can cut a further 3% of CO₂ emissions, an energy transition to renewable sources can cut 5%, clinker factor reduction can cut 10%, alternative raw materials in clinker can cut 6%, CCS can cut 43%, supply chain and logistics changes can cut 16% and the optimisation of construction can cut the remaining 5%.

President Roberto Callieri said “The cement and concrete supply chain wants to be one of the protagonists of the ecological transition.” He added “Only with adequate and immediate support tools will it be possible to prevent the impoverishment of the industrial fabric, preserve the competitiveness of the supply chain and prevent relocation. Last but not least, a new environmental culture must be shared, based on dialogue and no longer on the preconceived opposition to any choice of industry.”

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.”

South Korea: Sampyo Group has announced a planned investment of US$171m before 2030 to reduce Scope 1 and 2 CO₂ emissions by 35% over the period from an August 2021 baseline. The parent company of Sampyo Cement plans to achieve this in the first phase by increased its use of alternative fuels, improving energy efficiency, introducing low-carbon raw materials such as fly ash and developing sustainable products. The company is targeting net zero CO₂ production by 2050.

Philippines: Holcim Philippines plans to invest US$4.18m in upgrades to its cement plants at La Union, Bacnotan, and Lugait, Misamis Oriental to improve business and sustainability performance.

The subsidiary of Switzerland-based Holcim held a ceremonial signing ceremony on 7 July 2021 to award the contract to Sinoma CBMIPH Construction to install a drying facility at the La Union plant. The project is intended to reduce the fuel consumption of the unit by reusing hot gases from operations to dry materials. The integrated plant was recently awarded an ISO 45001:2018 for Occupational Health and Safety Management System and recertified for ISO 9001:2015 (Quality Management System) and ISO 14001:2015 (Environmental Management System) by certification body TÜV Rheinland. Holcim Philippines has also contracted Sinoma CBMIPH to install a drying facility at its Lugait plant that will reduce moisture of raw materials to improve grinding operations. The La Union and Lugait projects are scheduled to be completed in the first quarter of 2022 and by the end of October 2021 respectively.

In January 2021, Holcim Philippines also started projects worth US$2.42m to raise the efficiency of converting qualified waste materials to alternative fuels of its cement plant in Bulacan, Norzagaray. These will enable its Geocycle subsidiary to support the Bulacan plant to increase its thermal substitution rate by using more post-consumer and municipal solid wastes as alternative fuels.

South Korea: Korea Cement Association (KCA) members have agreed to reduce their net CO₂ emissions to zero by 2050. To help them achieve this target, the state-owned Korea Development Bank has pledged US876m in investments in emissions reduction and green production upgrades by 2025, according to the Maeil Business Newspaper. The KCA says that 90% of local cement producers have increased their environmental, social and corporate governance investment and reduced their use of coal.

France: Denmark-based FLSmidth has won a contract to supply a 400t/day calcined clay production line to Vicat’s Xeuilley integrated cement plant. The order includes flash calciner technology, an environmental control system and alternative fuel (AF) firing, handling and storage equipment. The line will have a design capacity of up to 525t/day and is scheduled for commissioning in 2023. It will enable clinker substitution in cement of up to 40%, according to the supplier. It says that cement produced using calcined clay will have a 16% smaller carbon footprint than its clinker-based equivalent. The value of the contract is Euro26.8m.

Vicat deputy chief executive officer Eric Bourdon said, “EU regulations and increasing demand for more sustainable cement has accelerated the decision to introduce clay as an environmental alternative to clinker in our production. With clay readily available in the area and positive results from pilots at FLSmidth’s test facilities in Denmark, we feel confident about the technology and hope to be able to expand further in the future.”

Croatia: Building materials producer Nexe Grupa invested a total of Euro15.3m in upgrades to its plants in 2020. This included subsidiary Našicecement’s capacity expansion at its Našice integrated cement plant. The producer also implemented alternative fuels substitution in the plant’s kiln line.
