US: Cemex USA and RTI International have secured US$3.7m in funding from the US Department of Energy for their Balcones cement plant amine technology carbon capture study. The plant in New Braunfels, Texas, will trial RTI International's non-aqueous solvent (NAS) system, licensed by energy and technology company SLB. Resources News has reported that the system will have a CO₂ capture capacity of 670,000t/yr. RTI International's principal project investigator Vijay Gupta said that NAS capture has a 30 - 40% lower energy penalty than preceding solvent-based technologies.

Cemex USA president Jaime Muguiro said "We remain committed to exploring technologies that can help us meet our targets as we build a more sustainable future. We are striving to cut emissions across all our operations, and this study with RTI International is one of the many steps Cemex is taking to achieve our objectives."

Mexico: Cemex has announced a raft of new carbon capture projects in Europe and North America. When commissioned, they will bring its total installed CO₂ capture capacity to over 3Mt/yr. The projects consist of three front-end engineering (FEED) studies to scale installations of Australia-based Leilac’s direct separation technology at Cemex cement plants in Germany, Poland and the US; a fourth FEED study for 95% capture installation at the Balcones, Texas, cement plant using RTI International's solvent capture technology and a development partnership for the cement industry's most comprehensive carbon capture, utilisation and storage (CCUS) studies at eight further cement plants in Europe, Mexico and the US.

Chief executive officer Fernando González said “CCUS brings together the essence of our strategic priorities: sustainability and innovation. Our Future in Action programme to achieve sustainable excellence and become a net-zero company is all about measurable, verified progress towards the most ambitious decarbonisation pathway in the industry. Although CCUS technologies are not ready to be scaled quite yet, it will take relentless work and innovation to ensure their viability in time to avoid the most damaging effects of climate change.”

US: Lehigh Hanson has announced the upcoming permanent closure of its Glens Falls cement plant in northeastern New York. Times Union News has reported that the producer has extended an offer of financial and job-hunting support to the plant's 85 employees. A phased closure will commence in 2023. The company said that 'changes to the competitive landscape within the context of a global cement industry' partly informed its decision, in addition to the 'small, aging and inefficient' condition of operations at the plant. Lehigh Hanson's Mitchell, Indiana, cement plant will cover the plant's market in future.

Lehigh Hanson Northeast regional president Alex Car said "We are committed to continuing to supply our customers in the New England region. We have the available capacity to meet the current and future needs of our customers, even after the Glens Falls plant halts production." Car added "We are thankful for the dedication and efforts of our Glens Falls workforce over the years and we will work to minimise the impacts to our employees and the community as much as possible."

Sweden: Germany-based KIMA Process Control has secured a contract for the supply of a kiln shell cooling system for Cementa's Slite cement plant in Gotland. 88 water jets will deliver centimetre-precision cooling for the 55m-long kiln, while IR pyrometers measure temperatures over areas of 10cm². According to KIMA Process Control, the equipment can avoid unnecessary cooling of the kiln shell, conserving the heat energy supplied by the main burner.

The new cooling system will eliminate the use of energy intensive electric fans, slashing 1700t/yr in CO₂ emissions, according to the supplier. It said that noise emissions will also 'drastically' decline as a result of the upgrade. The system's operating costs are reportedly 98% less than those of the plant's existing fan system.

The supplier said that the new equipment will 'bring the cement plant in Slite an economic benefit in the shortest possible time.' It said "For the cement industry, this project represents a new milestone in terms of best available technology in the operation of rotary kilns."

Singapore: Parliament passed the Carbon Pricing (Amendment) Bill earlier in November 2022. Under the act, Singapore will raise the price of carbon credits to US$18.17/t from 2024, and to US$32.71/t from 2026. CNA News has reported that the government said that the new legislation will provide the basis for the realisation of carbon credit prices of over US$36.31/t by 2030, in line with the country's 2050 net zero CO2 emissions commitment.

Polluters which emit over 25,000t/yr of CO₂ currently pay US$3.65/t for carbon credits.

South Korea: UK-based TCRK has announced a deal with Asia Cement to use its carbon capture and utilisation (CCU) technology at the cement producer’s plant in Jaechon. The project will see the first commercial deployment of TCRK’s CCUS technology from the first quarter of 2023. It will initially target 30,000t/yr of CO₂ equivalent and then ramp up to 120,000t/yr of CO₂ equivalent by mid-2024. The second target is intended to help Asia Cement reduce its emissions by 20% required to meet its 2025 decarbonisation plan.

TCRK’s approach will use two processes to utilise capture CO₂ from cement production. Its Arago Cement Process uses captured CO₂, cement kiln dust and by-pass particles to produce precipitated calcium carbonate, which TCRK uses to produce a product called Arago Cement. The captured CO₂ will also be used to grow microalgae in a process called bio-fixation. This method will offer 10% extra carbon storage capacity. The microalgae has a wide range of potential end-products including bioplastics and animal feed, and can also be used as a source of bio-cement production.

Europe: The Carbon Negative Biofuels from Organic Waste (Carbiow) project has received EU funding under the Horizon Europe initiative. Carbiow seeks to develop a dense, dry homogenous marine and aviation biofuel by carbonising gasification ash with oxygen and captured CO₂ from cement plants. 12 consortium members from the Benelux, Germany, Nordic countries, Slovenia and Spain are participating in the project.

Saudi Arabia: Yanbu Cement was among successful bidders in Saudi Arabia's largest carbon credit auction to date earlier in November 2022. The Saudi Public Investment Fund (PIF)’s Voluntary Carbon Market Initiative Auction sold 1.4Mt-worth of carbon credits to 15 different entities, of which Yanbu Cement was the only cement sector representative. The PIF said that the sale will support the country's Saudi Vision 2030 development goal, while also advancing its progress towards net zero CO₂ emissions by 2060.

Greece: Titan Group says that its updated 2030 greenhouse gas (GHG) emissions reduction targets have been validated by the Science Based Targets initiative (SBTi) as consistent with the levels required to limit a global temperature increase to 1.5°C. With the new targets the cement producer intends to tackle direct (Scope 1) emissions, indirect emissions from the generation of purchased electricity (Scope 2), and also other indirect emissions from the supply chain (Scope 3).

The company plans to reduce Scope 1 (gross), 2 and 3 (gross) GHG emissions covering in produced and purchased cement and clinker, by 25.1% per tonne of cementitious product sold by 2030, from a 2020 base year. Within this target it intends to reduce Scope 1 GHG emissions (gross) by 22.8% per tonne of cementitious product and to reduce Scope 2 GHG emissions by 58.1% per tonne of cementitious product from a 2020 base year. It also intends to reduce absolute Scope 3 GHG emissions from the use of sold fossil fuels by 42% from a 2021 base year. A Global Cement estimate suggests that it aims to reduce its specific net Scope 1 CO₂ emissions to around 520kgCO₂/t of cementitious product in 2030 compared to 654kgCO₂/t in 2021.

Mexico: Cemex says it has validated its 2030 decarbonisation goals through the Science Based Targets initiative (SBTi) for alignment under their new 1.5°C scenario. Under the new target the group plans to reduce its Scope 1 (direct) emissions by 47% less of CO₂ per ton of cementitious material and 35% less of carbon content in concrete compared to a 1990 baseline. A Global Cement estimate suggests that Cemex has set its 2030 target to around 425kg CO₂/t of cementitious product compared to 800kg CO₂/t in 1990 and 591kg CO₂/t in 2021.

The group also intends to reduce its Scope 2 (indirect) emissions via a 65% increase in sustainable electricity consumption. It aims to reduce its Scope 3 emissions through a 25% reduction in CO₂ per tonne of purchased clinker and cement, a 30% reduction in transport emissions, a 40% reduction of scope 3 emissions per tonne of purchased fuels and a 42% reduction in absolute scope 3 emissions from the use of traded fuels compared to a 2020 baseline.
