UK: Heidelberg Materials subsidiary Hanson has awarded a contract to Mitsubishi Heavy Industries subsidiary MHI Engineering for installation of a planned 800,000t/yr carbon capture system at its Padeswood cement plant in Flintshire. The producer plans to store its captured CO₂ in exhausted Irish Sea natural gas fields. MHI Engineering will carry out a pre-front-end engineering design study using its Advanced KM CDR solvent-based process. The supplier developed the process jointly with fellow Japan-based company Kansai Electric Power.

The project will be MHI Engineering's third of its kind at a cement plant, following similar commissions with Lehigh Cement in Canada and Tokuyama Cement in Canada.

Europe: The European Parliament (EP) of member states and the Council of the EU have concluded a provisional deal over plans for an EU carbon border adjustment mechanism (CBAM). Under the plans, importers of a range of emissions-intensive goods, including cement, will have to pay to obtain CBAM certificates for products entering the EU. Goods produced in countries with the same CO₂ emissions reduction measures as the EU will be exempt from requiring a certificate. CNBC News has reported that the mechanism will enter force with a transition period beginning in October 2023. This is subject to ratification by the EP and member states independently.

EP member for the Netherlands Mohammed Chahim said “CBAM will be a crucial pillar of European climate policies. It is one of the only mechanisms we have to incentivise our trading partners to decarbonise their manufacturing industry.”

India: Adani Cement has announced the launch of a dedicated waste processing subsidiary called Geoclean. Geoclean will process waste for recycling and use as alternative fuel (AF) in its cement production and alternative raw materials in its production of other building materials. Geoclean inherits the projects and all 14 waste management plants of its predecessor company Geocycle India. The Orissa Diary newspaper has reported that Geoclean aims to help Adani Cement to co-process 3.7Mt of AF over the five-year period up to the end of 2027. This would raise its subsidiaries ACC and Ambuja Cements’ AF substitution rate to 30%, from 6% in 2021.

Adani Cement CEO Ajay Kapur said "We are committed to building a sustainable future by adopting clean and green technologies in our overall business. We have always believed in environmental conservation, and are committed to making the optimum contribution towards co-processing waste responsibly for a sustainable future. Adani Cement will continue its endeavours to promote sustainability and build a cleaner and greener planet."

Colombia: Cemex has announced the launch of the Tunjuelo Circularity Centre at its former Tunjuelo quarry near Bogotá. Having rebuilt parts of the 50m-deep quarry with demolition waste, Cemex will now work on its ecological restoration, while continuing to receive excavation waste for reconstruction of the ground. It will meanwhile divert demolition waste deliveries for recycling in aggregate production. In Bogotá, Cemex has launched an initiative for urban construction partnerships in collaboration with local authorities. It will also collect municipal solid waste (MSW) there for use in its cement production and collect its used plastic cement bags for recycling in building materials production.

Cemex’s Colombia and Peru president Alejandro Ramírez said "This is a pioneering model for Cemex in the construction materials industry globally, which we aim to position as a benchmark for circularity within the sustainable development of large cities in Colombia and the world. A piece of land that supplied materials for Bogotá's development for decades has received construction and demolition waste for its redevelopment and was transformed into a green area to the south of the city, an epicenter of the circular economy and an opportunity for urban development for the capital city of Colombia." 


Kenya: Savannah Cement has hired China-based Sinoma International Engineering for construction of its upcoming 2.92Mt/yr Kitui clinker plant in Eastern Province. The plant will additionally have a 900,000t/yr grinding unit, a 35MW fossil fuel-fired captive power plant and a 13MW waste heat recovery (WHR) system. Savannah Cement chair Benson Ndeta said that the plant will convert to 100% solar and WHR-powered production by the end of 2029.

Sinoma International Engineering plans to commence the project immediately, and to complete it in late 2024.

Romania: Finance magazine Capital has named Holcim Romania as its Leader of the Sustainable Transition in the Construction Industry 2022 in recognition of the company’s CO₂ reduction initiatives.

The Holcim Group has committed to the net-zero emissions target; to achieve this ambitious target, we place sustainability at the heart of our strategy.” Piess concluded “We are aware of the impact of industry and the increase in consumption on climate change, which is why we have launched our ECOncept business model to build sustainably and responsibly.”

Holcim Romania’s ECOncept model comprises ECO Solutions, including 40% reduced-CO₂ ECOPlanet cement, ECO Services and ECO Score impact evaluations.

New Zealand: The Global Cement and Concrete Association has welcomed Fletcher Building’s concrete division as its first member from Oceania. Scoop News has reported that the concrete’s division’s business spans the entire concrete value chain, including 26 limestone and aggregates quarries and 80 ready-mix concrete batching plants. Its cement subsidiary Golden Bay Cement operates the 0.9Mt/yr Portland cement plant in Whangārei, New Zealand.

Fletcher Building concrete division CEO Nick Traber said "Fletcher Building firmly believes we can play a significant part in a carbon zero and circular future. Our Golden Bay EcoSure cement is one of the lowest-carbon cements in the world already, with 13 - 22% less embodied carbon than imported products. We believe having access to the global research and knowledge from the GCCA will help us improve this further and continue to lead Australasia in best practice decarbonisation of the built environment."

Mexico: Cemex Mexico plans to install hydrogen injection systems at four cement plants across Mexico. The producer will use the technology to increase alternative fuel (AF) substitution at the plants by 8 - 10%. A 40% reduction in Scope 3 purchased fuel emissions forms part of Cemex's 2020 - 2030 CO₂ emissions reduction strategy. Through the decarbonisation and circular economy pillars of its Future in Action plan, the group aims to become carbon neutral by 2050.

Cemex Mexico president Ricardo Naya said "Hydrogen is a key technology to accelerate the implementation of our climate action roadmap."

The El Financiero newspaper has reported that Cemex set a new group record AF substitution rate of 34% in September 2022. It uses hydrogen at all of its European cement plants and at one plant in the Dominican Republic.

Brazil: Votorantim Cimentos has revised its Scope 1 CO₂ emissions reduction goal down to 475kg/t of cementitious product by 2030, from 520kg/t previously. The new target is 8.7% lower than the previous one, which it set in November 2020. Votorantim Cimentos previously reduced its emissions per tonne by 20% between 1990 and 2021. The group's targeted reduction from a 2018 base year now equates to 25%. The Science-Based Targets Initiative (SBTi) validated the ambitious target on 1 December 2022.

Votorantim Cimentos expects to achieve its aim through increased alternative fuel (AF) co-processing, substitution of supplementary cementitious materials, improved efficiency and use of renewable power and the development of new technologies, including carbon capture.

The group's global sustainability, institutional relations, product development and engineering director Álvaro Lorenz said “The fight against the negative effects of climate change is at the heart of our strategy and reflects our focus on competitiveness and on creating a positive legacy. The most competitive businesses will be those with the lowest greenhouse gas emissions. After all, the environmental crisis is also an economic and social crisis. The validation of our new target by SBTi reinforces our commitment and continuous efforts toward the net-zero agenda.”
