The company says that its products will be able to eliminate 100,000t/yr of industrial CO2 emissions nationally. N + P Group will use locally sourced waste at the unit.
Chief development officer Lars Jennissen said “Obtaining the environmental and construction permit is a major achievement for us, and we thank our colleagues and partners for their hard work in realising this important milestone. The new location will contribute to the circular economy in Hauts-de-France by converting regional non-recyclable wastes into new resources for regional customers, and it offers a massive potential CO2 savings for the French market.”
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."
Cemex announces raft of carbon capture projects
22 November 2022Mexico: 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.”
Lehigh Hanson will permanently close Glens Falls cement plant
18 November 2022US: 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."
KIMA Process Control to supply kiln cooling system for Cementa's Slite cement plant
17 November 2022Sweden: 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."
Singaporean parliament enacts tightened carbon credit scheme
17 November 2022Singapore: 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.
TCRK announces carbon capture project with Asia Cement
16 November 2022South 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.
