Philippines: Holcim Philippines has appointed I Squared Capital subsidiary Berde Renewables to build, maintain and operate two rooftop solar power plants, at its Bulacan and La Union cement plants, respectively. The solar power plants will have a combined capacity of 7.8GWh/yr and reduce Holcim Philippines’ CO2 emissions by 5500t/yr. The Business Mirror newspaper has reported that the projects advance the producer’s aim to reduce its energy-related CO2 emissions by 65% between 2018 and 2030.

Holcim Philippines president and CEO Horia Adrian noted the 20% reduction in overall CO¬2 emissions that the company has already achieved up to 2022 and said “This project further strengthens our ability to support Holcim's net zero direction and the country's nationally determined contributions.”

Switzerland: Reduced-CO₂ cement catalyst developer Nanogence has secured an undisclosed sum from a consortium of investors led by investment fund CirCap. Nanogence’s catalyst reduces the CO₂ emissions of cement production by 40%, without changing production processes. Tech EU News has reported that the catalyst is capable of increasing cement’s strength and durability compared with that of ordinary Portland cement (OPC) produced without it. Prior to the latest financial development, the company had raised US$2.7m-worth of funding.

CEO Abhishek Kumar said “We are excited to receive the support from incoming renowned investors in this essential journey to accelerate the transition towards a low carbon built world. With growing demand worldwide, we need to align with like-minded strong backers for our growth phase.”

Mexico: Cemex has updated its sustainability-linked financing framework in line with its latest emissions reduction targets of 475kg/t of CO₂ per tonne of cementitious material. Under the new framework, Cemex will issue up to US$350m-worth of sustainability-linked bonds on the Mexican Stock Exchange. The group plans to use the funds to refinance debt, as well as for ‘general corporate purposes.’ It aims to acheive 85% sustainability-linked financing by 2030.

Cemex said "The proceeds will be used exclusively for eligible green projects in pollution prevention and control, renewable energy, energy efficiency, clean transportation, sustainable water and wastewater management, production technologies and processes adapted to the circular economy and/or eco-efficient products.”

France: Cem'In'Eu has launched FUSIOCIM, a CEM II/C pozzolan cement, that offers a 43% reduction in CO₂ emissions compared with ordinary Portland cement (OPC). FUSIOCIM has specific CO₂ emissions of 506kg/t. It is suitable for various concrete applications and comes in 25kg bags.

Cem’In’Eu general manager Fabien Charbonnel said "We created Cem’In’Eu with the ambition of reducing the carbon footprint of the cement industry. And we are proving it today with a low-carbon offer that easily replaces traditional cements, without any change for construction professionals. We are convinced that this transition can only be done with pragmatism and taking into account the needs of users.”

US: In 2022, Fortera began building a 15,000t/yr-capacity plant to produce its low-carbon cementitious material, Fortera Reactive Calcium Carbonate (RCC), at CalPortland's Redding cement plant in California. The commercial-scale plant will produce a reactive form of calcium carbonate using CO₂ from the kiln of the 600,000t/yr cement plant. Fortera's process converts 1t of limestone into 1t of Fortera RCC by capturing and mineralising CO₂ from the cement plant's kiln. Fortera cement production emits 60% less CO₂ than ordinary Portland cement (OPC). The 15,000t/yr plant will operate at 20 times the scale of previous pilot tests. The Redding Record newspaper has reported that 15 workers will be employed at the site.

Former Redding cement plant owner Lehigh Hanson formed an agreement with Fortera to collaborate on the low-carbon cement plant project in March 2021. The plant subsequently switched ownership to Martin Marietta Materials in October 2021, before CalPortland bought it in July 2022.

Argentina: Cementos Avellaneda has inaugurated its 22MW La Calera solar power plant in San Luis Province. Forbes has reported that the power plant will supply electricity to the producer's 1.1Mt/yr San Luis cement plant. As a result, operations at the plant will henceforth be 55% renewably powered. In total, the new solar power plant will eliminate 22,600t/yr-worth of CO₂ emissions. Engineering company Industrias Juan F Secco supported the installation of the US$25m plant, which took 16 months to build.

Cementos Avellaneda's general director José Luis Maestri said "It was key to the success of this project to have been able to find a strategic partner such as Industrias Juan F Secco, an Argentine company with more than 80 years of history and experience in the energy sector, which provided us with all its professionalism and commitment."

UAE: Lafarge Emirates Cement, part of Holcim, has awarded a contract to Mitsubishi Heavy Industries Group subsidiary Turboden to supply and install a 10MW waste heat recovery (WHR) system at its Fujairah cement plant. The system relies on ENGIE Solutions' organic Rankine cycle technology. The supplier says that the installation will reduce the 3.2Mt/yr cement plant's energy-related CO₂ emissions by 29,000t/yr (28%).

Turboden CEO Paolo Bertuzzi said "We are proud that Holcim Group, already our customer for three other WHR plants, has again chosen Turboden for this first project in the UAE. At COP 28, this year in the UAE, we will have the opportunity to present this energy-saving and CO₂-reducing project to raise awareness in energy intensive industries."

China: Asia Cement has launched its 2050 decarbonisation strategy, entitled 'Net-Zero Carbon Emissions By 2050 - Asia Cement Advanced Deployment.' The strategy consists of multiple pillars, namely 'alternative fuels,' 'reducing cement's clinker factor,' 'increasing renewable energy reliance' and 'carbon capture.'

During 2022, Asia Cement reduced its limestone, clay, iron and sand consumption by 266,000t, its coal consumption by 17,000t and its gypsum consumption by 56,000t year-on-year. This eliminated 95,100t of CO₂ emissions throughout the year, according to the producer.

US: The Portland Cement Association (PCA) hosted a one-day session in mid-June 2023 aimed at establishing guidelines for the definition of 'low carbon' cement and concrete. The association called the session a 'Critical first step' towards ensuring clarity for stakeholders.

The PCA said "Low carbon is increasingly defined in the eye of the beholder, with little or no regard to either upstream and downstream impacts or short-term and long-term strength, durability and resilience concerns."

UK: Mineral Products Association Lime (MPA Lime), the body representing the UK lime sector, has launched the Net Negative 2040 Roadmap. The association said that the roadmap sets out the strategy for its to 'go beyond net zero' by 2040. The industry will rely on the deployment of fuel switching, carbon capture, renewable energy sources and green transport technologies, among other approaches. It called on the government to support its aims through the implementation of carbon accounting, subsidisation of renewables and decarbonisation technologies, the development of green hydrogen infrastructure, ensuring that UK lime can remain competitive in the UK and overseas markets.

MPA Lime director Mike Haynes said “Each lever will contribute to decarbonisation – many initiatives are happening already or will come on stream this decade." He added "The combination of using biomass fuels with carbon capture and lime product carbonation will result in removal of 250,000t/yr of atmospheric CO₂, making the sector net negative overall. Other levers, especially indirect emissions and transportation, require broader collaboration and enabling action by government and other industries.”

Through their actions to date, MPA Lime members reduced their absolute CO₂ emissions by 25% between 2005 and 2022.
