LafargeHolcim, ArcelorMittal, Evonik and Solvay form partnership to reduce carbon emissions across industries
17 November 2016Morocco: LafargeHolcim, ArcelorMittal, Evonik and Solvay have formed a Low Carbon Technology Partnerships Initiative across the steel, cement and chemicals industries. This new partnership will look at the potential synergies that exist between the manufacturing processes of these three energy intensive sectors, and how these synergies could be harnessed to reduce CO2 emissions.
As a first step, and following preliminary research, the innovative partnership will produce a study with the technical support of Arthur D Little to identify potential ways to valorise industrial off-gases and other by-products from their manufacturing processes to produce goods with a lower carbon footprint than through the fossil path. The preliminary research has already allowed identification of significant potential in selected trans-sector pathways.
The study is aimed at bringing a fact-based overview of carbon and energy sources from industrial off-gases (first at a European level), and evaluating the technical, environmental and economic feasibility of different Carbon Capture and Usage (CCU) pathways and their potential.
Initial findings from the first step already underway suggest that deploying cross-sector carbon capture and reuse opportunities on an industrial scale could reduce up to 3 GT/yr or 7% of global anthropogenic CO2 emissions. Existing conversion technologies that could be deployed across the three sectors could utilise by-products in the off-gases to create building materials, organic chemicals and fuel. Increased availability and greater access to renewable energy sources would significantly boost net carbon reduction efforts by those three sectors, within a supportive legislative framework. Cross sector carbon capture and reuse should also result in job creation, to be further investigated.
The study, carried out at European level, is building the ground for similar investigation extended at global level and paves the way for identifying and assessing industrial scale projects on CCU at the interface between the sectors.
“Concrete offers the highest level of life-cycle sustainability performance and we are continuously developing new products and solutions for a low carbon society. This new ambitious partnership will support our mission to cut our net emissions per ton of cement by 40% towards 2030 (versus 1990) and to develop and further deploy low carbon solutions for the construction sector. But to make this a reality, we will need an enabling regulatory framework and support for innovation,” said Bernard Mathieu, Head Group Sustainable Development of LafargeHolcim.
Taiwan: Taiwan Cement plans to expand its microalgae unit to boost astaxanthin production from waste CO2. The cement producer intends to invest US$6.25m towards enlarging its existing microalgae unit into a 20-hectare outdoor microalgae farm with an estimated annual production value of about US$12m, according to the Tapei Times.
The upgraded farm will start operation in 2017 producing astaxanthin, an input for skincare and health food products. The company hopes to make astaxanthin products that meet universal standards, such as the Good Manufacturing Practice standard, eventually becoming the country’s main supplier of the chemical.
To support the upgrade Taiwan Cement has signed a business development contract with the Industrial Technology Research Institute (ITRI). The two organisations have collaborated since 2011 on developing CO2 capture technology. As part of the new deal Taiwan Cement is expected to decrease its CO2 emissions by 4800t/yr.
LEILAC secures Euro12m from European Union to demonstrate Calix carbon capture technology
21 April 2016Europe: The Low Emissions Intensity Lime And Cement (LEILAC) consortium has secured Euro12m in funding over five years from the European Commission Horizon 2020 Grant programme to test Calix’s direct separation process to capture CO2 emissions from cement and lime production. The consortium comprises HeidelbergCement, Cemex, Tarmac, Lhoist, Amec Foster Wheeler, ECN, Imperial College, PSE, Quantis and the Carbon Trust. The consortium will also contribute a further Euro9m towards the project.
During the first three years, the project will focus on finalising the design of the demonstration plant, to be constructed at the HeidelbergCement plant in Lixhe, Belgium once the necessary permits have been secured. The high temperature Direct Separation Calciner pilot unit will then undergo two years of testing in a standard operational environment, at a feed rate capacity of 240t/day of cement raw meal and 200t/day ground limestone respectively, on a continuous basis for several weeks.
Fundamental research on the process demands and performance will be carried out to demonstrate that the technology works sufficiently and robustly enough to be scaled up to full operational use. The project results will be shared widely with industry at key intervals during the testing.
Calix’s direct separation technology is achieved by re-engineering the process flows used in the best available technology for lime and cement calcination. Carbonate calcination occurs by indirect counterflow heating, and consequentially the flue gases are not mixed with the CO2 emitted from the carbonate minerals. This technology is already operating at a commercial scale for magnesite calcination. It does not require any separation technologies, new materials or processes. The technology is complementary with other carbon capture methods already developed in the power and cement sector, such as oxyfuel, and can make use of alternative fuels.
