Taiwan: Taiwan Cement Corporation has signed a memorandum of understanding (MoU) with ThyssenKrupp Polysius. Under the MoU, the partners will implement carbon capture projects aimed at capturing 100,000t/yr (10%) of Taiwan Cement Corporation’s CO₂ emissions by 2030. This will involve the development of a new generation of pure oxygen carbon capture technology in Line 1 of Taiwan Cement Corporation’s Hualien Heping cement plant. This technology aims to increase the concentration of captured CO₂ to over 90% and reduce the energy consumption of carbon capture. The Hualien Heping plant project will conclude in 2026, with the commercialisation of the technology to follow before 2030. Taiwan Cement Corporation plans to supply its own captured CO₂ to various other industries, including industrial welding, chemicals and food processing.

Taiwan Cement Corporation chair Zhang Anping said "Cement has created the civilised society we live in today, and Taiwan Cement Corporation will continue to participate in energy transformation and support the development of future civilisation. This cooperation with Polysius, a golden brand in the cement industry, is to solve the problem of greenhouse gas emissions, creating the future not only for the cement industry but for the whole world."

Austria/Australia: RHI Magnesita has signed a deal with Australia-based carbon capture company MCi Carbon for the construction of a large-scale carbon capture plant at its Hochfilzen dolomite plant in Tyrol, Austria. Prior to construction of the large-scale system in Austria, the companies will partner to test and scale-up MCi Carbon’s technology at the latter’s Myrtle demonstration plant in New South Wales, Australia. The Myrtle demonstration plant will aim to capture 1000t/yr of CO₂.

RHI Magnesita CEO Stefan Borgas said "The partnership with MCi Carbon is forward-looking and their technological approach is particularly interesting because it combines carbon capture storage and carbon utilisation. This is currently the most promising way for the refractory industry to reduce process emissions."

MCi Carbon CEO of Marcus Dawe said "This investment marks a pivotal moment for MCi Carbon and underscores the trust our partners place in our transformative technology. With RHI Magnesita's support, we are poised to accelerate our global commercialisation efforts and address the challenges faced by heavy industries in achieving decarbonisation."

Switzerland/UAE: The COP28 UAE Presidency named École Polytechnique Fédérale de Lausanne (EPFL) among its Energy Transition Changemakers in the Heavy Emitting Sectors category. EPFL won the prize for its LC3 limestone calcined clay cement, which replaces 50% of clinker content with calcined kaolinite clay and limestone. LC3 cement reduces CO₂ emissions by 40% compared to ordinary Portland cement (OPC), and is a readily available solution that can be scaled worldwide. EPFL noted the special importance of LC3 cement for CO₂ reduction efforts in developing countries, and sees it as having the potential to eliminate 500Mt/yr of global CO₂ emissions by 2030. In a post to LinkedIn, the LC3 Project said that nine plants around the world currently produce LC3 cement, with a further 20 planned before 2025.

Cementos Molins has been celebrating the first anniversary this week of its alternative raw materials unit at its Sant Vicenç dels Horts plant near Barcelona. It has processed 75,000t of waste since September 2022 when the site started up. More is yet to come as the unit has a production capacity of up to 200,000t/yr. The facility receives waste in coarse, granular, powder and sludge formats. Waste from concrete plants is crushed and screened to produce recycled aggregate. Industrial and construction waste is dosed and homogenised to produce alternative raw materials for cement production.

Global Cement Weekly has covered construction and demolition waste (CDW) a couple of times already so far in 2023. A number of cement producers are investing in the sector - including Holcim, Heidelberg Materials, CRH, Cemex – by developing technology, buying up other companies, setting up internal CDW divisions and so on. Holcim and Heidelberg Materials have been the more obviously active participants over the past six months based on media coverage. In September 2023 Holcim France commissioned the Saint-Laurent-de-Mûre alternative raw materials plant and Holcim Group invested in Neustark, a company promoting technology to sequester CO₂ in CDW. In August 2023 Lafarge Canada also completed the first stage of a pilot project to use CDW in cement production at its St. Constant plant in Quebec. Heidelberg Materials meanwhile announced in October 2023 that a forthcoming upgrade to its Górażdże cement plant in Poland would include a new CDW recycling unit and in September 2023 it launched a CDW division for its subsidiary Hanson UK.

Previously we have described how the European Union (EU) has set recovery targets for CDW. However, McKinsey & Company published research in March 2023 setting out the economic case for cement and concrete companies looking at CDW. It estimated that “an increased adoption of circular technologies could be linked to the emergence of new financial net-value pools worth up to roughly Euro110bn by 2050.” It is not a certainty and there is risk involved, but adopting circular practices is one way to reduce this risk. It then went on to predict that recirculating materials and minerals could generate nearly Euro80bn/yr in earnings before interest, taxation, depreciation and amortisation (EBITDA) for the cement and concrete sectors by 2050. The biggest portion of this could come from using CDW in various ways such as a clinker replacement or as an aggregate in concrete production, or the use of unhydrated cement ‘fines.’ Capturing and using CO₂ and increasing alternative fuels (AF) substitution rates would have a financial impact but not to the same scale.

Graph 1 above puts all of the McKinsey circular technology suggestions in one place with the prediction that all of these methods could reduce CO₂ emissions from cement and concrete production by 80% in 2050 based on an estimated demand of 4Bnt/yr. The first main point they made was that technologies using CO₂, such as curing ready-mix or precast concrete, can create positive economic value at carbon prices of approximately Euro80/t of CO₂. Readers should note that the EU emissions Trading Scheme CO₂ price has generally been above Euro80t/yr since the start of 2022. The second point to note is that using CDW could potentially save money by offering CO₂ abatement at a negative cost through avoiding landfill gate fees and reducing the amount of raw materials required. This is dependent though on government regulation on CO₂ prices, landfill costs and so on.

Cement producers have been clearly aware of the potential of CDW for a while now, based on the actions described above and elsewhere, and they are jockeying for advantage. These companies are familiar with the economic rationale for AF and secondary cementitious materials (SCM) in different countries and locations. CDW usage is similar but with, in McKinsey’s view, existing CO₂ prices, landfill costs, and regulatory frameworks all playing a part in the calculations. Graph 1 is a prediction but it is also another way of showing the path of least resistance to decarbonisation. It is cheaper to start with AF, SCMs and CDW rather than barrelling straight into carbon capture. The beauty here is that cement and concrete sold, say, 50 years ago is now heading back to the producers in the form of CDW and it still has value.
