Titan Group tightens emissions reduction commitments
27 October 2022Greece: Titan Group has set new CO2 reduction targets by adding Scope 3 emissions. Titan Group had previously committed to a 21% Scope 1 emissions reduction and a 42% Scope 2 emissions reduction per tonne of cementitious material between 2020 and 2030. Titan Group reduced its total CO2 emissions by 20% between 1990 and 2021, and by 5.5% year-on-year in the third quarter of 2022. Its latest targets are currently under review by the Science-Based Targets Initiative (SBTi).
Titan Group chair Marcel Cobuz said “The initiatives in our decarbonisation roadmap offer significant business growth opportunities. Our technology and sales teams across all our markets are focused on decarbonising our operations more quickly and offering our customers more and more sustainable and circular solutions.”
Austria: Rail logistics company ÖBB Rail Cargo Group (RCG) says that its haulage of 80,000t/yr of granulated blast furnace slag (GBFS) and clinker to and from w&p Zement's Wietersdorf cement plant in Carinthia by rail has removed 3200 trucks/yr from the road since its start in 2019. RCG's trains deliver the plant's clinker to the Peggau-Deutschfeistritz railway station in Styria, and return to the plant laden with GBFS from steel producer Voestalpine's nearby Leoben refinery.
RCG said that w&p Zement is currently working to increase its operations' reliance on rail, adding "Further innovative transport solutions are already being worked on."
Taiheiyo Cement agrees to buy Denka’s cement business
26 October 2022Japan: Taiheiyo Cement has agreed to buy the cement business of chemicals company Denka for an undisclosed sum. Denka operates an integrated plant in Itoigawa City, Niigata Prefecture where Taiheiyo Cement’s subsidiary Myojo Cement also operates a plant. The three companies have been working on a joint-development plant for local limestone resources since 2018. However, Denka has decided to leave the cement market due to poor local demand and the necessity of upgrades at its plant from 2025 onwards.
From April 2023 cement sold from Denka’s Omi plant will carry the Taiheiyo Cement brand name. Taiheiyo Cement and Myojo Cement have also agreed to continue supplying Denka’s other businesses, such as carbide production, with limestone from 2025. Denka will send by-products and other waste streams to the cement producer. Finally, Taiheiyo Cement, Myojo Cement and Denka will carry on developing the local limestone resources near to Itoigawa City.
Betolar launches Geoprime concrete products in India
11 October 2022India: Finland-based Betolar has launched its first concrete products manufactured using Geoprime on the Indian market. Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). The new concrete product range consists of precast blocks, paving slabs and tiles, and is currently on display at World of Concrete India in Mumbai, Maharashtra.
Betolar's India managing director Abhishek Bhattacharya said "We are happy to introduce our first products to our customers for the Indian markets. We have now moved from laboratory tests into the production phase, and can show concretely how well this solution works. It is great to hear the feedback from the concrete industry in the region to our sustainable solution. Decarbonisation of the concrete industry is a very current and important topic."
Cemex Panama secures solid recovered fuel supply from EMG
04 October 2022Panama: Waste management company EMG has won a contract with Cemex Panama for the supply of solid recovered fuel (SRF) derived from commercial and industrial waste, beginning in early 2023. EMG is working to expand its SRF production capacity to 18,000t/yr from the start of the supply contract.
Hoffmann Green Cement Technologies to supply concrete for glass wool recycling plant
03 October 2022France: Hoffmann Green Cement Technologies is supplying its low-CO2 clinker-free cement for the construction of an industrial prototype glass wool recycling plant in Chemillé-en-Anjou by Saint-Gobain subsidiary Isover. The company will supply its H-UKR cement for use in the facility’s foundations.
Hoffmann Green Cement Technologies co-founders Julien Blanchard and David Hoffmann said "This unprecedented project is totally in line with what we want to embody since the creation of Hoffmann Green: the promotion of the circular economy in the construction sector through the revalorisation of waste from industry."
Innovative Ash Solutions launches supplementary cementitious material made from incinerator waste
27 September 2022UK: Innovative Ash Solutions, a joint venture of Levenseat and Organic Innovative Solutions, has launched a new air pollution control residue (APCR)-based supplementary cementitious material (SCM). The supplier produces the material at its Lanarkshire treatment facility using APCR local from municipal solid waste (MSW) and wood biomass incinerators. Innovative Ash Solutions has received planning permission for a 54,000t/yr industrial-scale APCR-based SCM plant, and plans to establish a total of three plants in the UK, one of which will reach a capacity of 500,000t/yr. It has also signed an exclusive licensing agreement with an Australia-based importer for the material.
The SCM is designed to replace pulverised fly ash (PFA), of which the UK imported 325,000t in 2019, more than four times its 2012 import volumes of 76,000t.
Innovative Ash Solutions director Robert Gren said “We are excited to bring this new product to market. Innovative Ash Solutions is the first and, so far, the only company in the UK to have achieved ‘End of Waste’ accreditation for a PFA replacement for this type of use. Our research shows there is potential to produce more than 500,000t/yr of PFA replacement from UK APCRs every year, which would reduce the need for importing materials and support the decarbonisation of cement and concrete products.”
US: A team from Washington State University (WSU) and Pacific Northwest National Laboratory has successfully used waste crustacean shells in the production of concrete. ZME Science News has reported that the materials consist of calcium carbonate and 20 – 30% chitin, a nanoparticle biopolymer. When used as an additive in concrete production, the shells increase the set product’s compressive strength by 12% and its flexural strength by 40%. The team is now developing a methodology for the industrial-scale production of shell-based additives.
WSU researcher Professor Michael Wolcott said “Those are very significant numbers. If you can reduce the amount that you use and get the same mechanical function or structural function and double its lifetime, then you’re able to significantly reduce the carbon emissions of the built environment.”
PGE Group to establish cement facility in Bełchatów
22 July 2022Poland: PGE Group is ordering a feasibility study for a planned new cement production facility in Bełchatów county. Polish News Bulletin has reported that the plant will take advantage of locally available fly ash from coal-fired power plants.
Australia: Hallett Group plans to establish a slag cement grinding plant in Port Augusta, South Australia. Magnet News has reported the cost of the project as US$83.9m, towards which the producer has received US$13.4m in government funding. The plant will produce cement using South Australian ground granulated blast furnace slag (GGBFS) from Nyrstar’s Port Pirie and Liberty Primary Steel’s Whyalla steel refineries and fly ash from the site of the former Port Augusta power plant. Its operations will be 100% renewably powered. An accompanying new distribution facility at Port Adelaide will ship the cement to markets. The project will create 50 new jobs.
When the Port Augusta grinding plant becomes operational in 2023, its products will reduce regional CO2 emissions by 300,000t/yr, subsequently rising to 1Mt/yr, according to the company’s expansion plans.
Hallett Group chief executive officer Kane Salisbury said "We're talking about 1% of the entire country's 2030 [CO2 reduction] commitment, delivered through this project." Salisbury added "We're looking at turning South Australia into a global leader in manufacturing green cement."
