Dalmia Cement threw down the gauntlet this week with the announcement of a large-scale carbon capture unit (CCU) at one of its plants in Tamil Nadu, India. An agreement has been signed with UK-based Carbon Clean Solutions Limited (CCSL) to use its technology in building a 0.5Mt/yr CCU. The partnership will explore how CO₂ from the plant can be used, including direct sales to other industries and using the CO₂ as a precursor in manufacturing chemicals. No exact completion date or budget has been disclosed.

The move is a serious declaration of intent from the Indian cement producer towards its aim of becoming carbon neutral by 2040. Dalmia has been pushing its sustainability ‘journey’ for several years now hitting targets such as reaching 6Mt of alternative raw materials usage in its 2018 financial year and reaching a clinker factor of 63% at the same time. In an article in the November 2018 issue of Global Cement Magazine it said it had achieved CO₂ emissions of 526kg/t from its cement production compared to 578kg/t from other Indian members of the Cement Sustainability Initiative (CSI). In its eastern operations it had gone further to reach 400kg/t.

Using CCU is the next step to this progression but Dalmia’s approach is not without its caveats. Firstly, despite the size of the proposed project it is still being described as a ‘large-scale demonstration.’ Secondly, the destination of all that captured CO₂, as mentioned above, is still being considered. CCSL uses a post-combustion capture method that captures flue gas CO₂ and then combines the use of a proprietary solvent with a heat integration step. Where the capture CO₂ goes is vital because if it can’t be sold or utilised in some other way then it needs to be stored, putting up the price. Technology provider CCSL reckons that its CDRMax process has a CO₂ capture price tag of US$40/t but it is unclear whether this includes utilisation sales of CO₂ or not.

The process is along similar lines to the Skyonic SkyMine (see Global Cement Magazine, May 2015) CCU that was completed in 2015 at the Capitol Cement plant in San Antonio, Texas in the US. However, that post-combustion capture project was aiming for 75,000t/yr of CO₂. Dalmia and CCSL’s attempt is six times greater.

Meanwhile, Cembureau, the European cement association, joined a group of industrial organisations in lobbying the European Union (EU) on the Horizon Europe programme. It wants the budget to be raised to at least Euro120m with at least 60% to be dedicated to the ‘Global Challenges and European Industrial Competitiveness’ pillar. This is relevant in a discussion on industrial CO₂ emissions reduction because the scheme has been supporting various European cement industry projects, including HeidelbergCement’s work with the Low Emissions Intensity Lime And Cement (LEILAC) consortium and Calix at its Lixhe plant in Belgium and its pilots in Norway. As these projects and others reach industrial scale testing they need this money.

These recent developments provide hope for the future of the cement industry. Producers and their associations are engaging with the climate change agenda and taking action. Legislators and governments need to work with the cement sector to speed up this process and ensure that the industry is able to cut its CO₂ emissions while continuing to manufacture the materials necessary to build things. Projects like this latest from Dalmia Cement are overdue, but are very encouraging.

Switzerland: LafargeHolcim’s executive committee has taken on Magali Anderson in the newly-created role of Chief Sustainability Officer. Anderson is a mechanical engineer with extensive managerial and functional experience who joined LafargeHolcim in 2016 as its Head of Health and Safety. LafargeHolcim CEO Jan Jensich has stated that the appointment “will accelerate LafargeHolcim’s vision of running its operations with zero harm to people and the environment.”

UK: The body responsible for the UK’s 15 National Parks has acknowledged the building materials and construction company Tarmac as its lead partner in recognition of its sustainable practice at the UK National Parks Conference at the Yorkshire Dales National Park headquarters. The Conference on the occasion of the 70^th anniversary of the inauguration of the National Parks was supported by Tarmac.

Sri Lanka: INSEE Cement has launched its first Global Reporting Initiative (GRI) based and externally assured sustainability report. The report was officially made public at an event in Colombo featuring a panel discussion on sustainability.

Germany: HeidelbergCement’s specific CO₂ net emissions per tonne of cementitious material fell by 1.4% year-on-year to 599kg CO2/t in 2018 from 608kg CO₂/t in 2017. Despite this its absolute gross CO₂ emissions increased by 3% to 76.7Mt from 74.2Mt as clinker, cement, aggregate and concrete sales volumes all grew in 2018. The group has published the data in its Sustainability Report for the 2018 financial year.

“Cutting our CO₂ emissions and handling natural resources considerately are priorities for all our business lines,” says Bernd Scheifele, chairman of the managing board of HeidelbergCement. "We focus primarily on the development of sustainable products and the implementation of concrete measures at plant level in order to achieve our sustainability goals.” The company has set itself the target of a 30% reduction in its specific net CO₂ emissions per tonne of cement by 2030, compared with 1990. HeidelbergCement says it intends to realise its vision of CO₂-neutral concrete by 2050 at the latest.

Other figures of note in the report include an alternative fuels substitution rate of 21.7% in 2018 compared in 20.8% in 2017. NO_x, SO_x and particulate matter emissions all fell. However, total water withdrawal rose by 8% to 65.4Mm³ from 60.4Mm³ although water consumption fell.

UK: The Institutional Investors Group on Climate Change (IIGCC) has called on European building materials companies to take steps to fight climate change or face commercial extinction. Recommended changes from its new ‘Investor Expectations of Companies in the Construction Materials Sector’ report have been sent to the heads of LafargeHolcim, HeidelbergCement, CRH and Saint-Gobain. The report informs investor engagement with other construction material firms on the initiative’s global list of 161 focus companies. Investment bodies in the group represent US$2Tn in assets, assets under management and under advice.

“The cement sector needs to dramatically reduce the contribution it makes to climate change. Delaying or avoiding this challenge is not an option. This is ultimately a business-critical issue for the sector,” said Stephanie Pfeifer, the chief executive officer (CEO) of the IIGCC. “Major economies such as the UK and France are increasingly adopting economy-wide net zero emission targets. The cement sector needs to get ahead of the profound transformation their sector faces by addressing barriers to decarbonisation in the short- to medium-term if companies are to secure their future.”

Key details set out in the ‘Investor Expectations’ report include becoming carbon neutral by 2050. Companies are expected to set short, medium and long-term science-based targets to reach this goal. Building material companies should be public policy transparent and advocate for the Paris Agreement, they should implement a ‘strong’ governance framework assigning specific responsibility for climate change to a board committee or board member and they should provide enhanced corporate disclosure in line with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD).

The IIGCC recognised the steps HeidelbergCement in particular has taken in already having committed to meeting key aspects of the investor expectations it has outlined. CRH, LafargeHolcim and Saint-Gobain have been encouraged to follow suit, given the ‘significant’ role they play as European-based multinationals. The group also praised the ambitious targets set by India’s Dalmia Cement to become carbon negative by 2040.

France: Lafarge France plans to launch a reusable cement pallet scheme in October 2019. The new single-size wooden pallets for bagged cement will be reinforced for use at least six times. They will be used at all of the company’s sites across its range of bagged cement products. The pallets will also include Lafarge branding. A saving of 7500t/yr of wood is anticipated. The scheme is part of the Lafarge 360 initiative.

France: Lafarge France has launched its Lafarge 360 initiative. The scheme aims to aid specifiers, contractors and builders make low-carbon structures through reducing CO₂ emissions, preserving natural resources and responsible innovation. It will start the initiative by proving a Lafarge 360 score on its associated digital platform to allow customers to assess the environmental impact of Lafarge’s products. By providing a rating of A to D the tool will offer information on the concrete types.

Italy: Buzzi Unicem says that its Unical subsidiary is the first national concrete producer to earn silver level RSS certification from the Concrete Sustainability Council. The accreditation asserts that a company meets criteria for sustainable practices and operates in a sustainable, environmentally positive manner. Unical’s Strada Berlia concrete batching plant in Turin received the certification in June 2019. The CSC procedure also included certifying the cement produced by Buzzi Unicem’s Robilante Cement plant and the aggregates from Ceretto quarry. The certificate was issued by ICMQ, the Italian Certification Body member of CSC. Unical manages more than 100 concrete plants in Italy.

Japan: Taiheiyo Cement has set an 80% CO₂ reduction target from cement production by 2050. It also plans to reduce its emissions from cement products by 20%. It aims to do this via a variety of means including energy-saving measures, promoting co-processing, lowering the clinker factor of its cement and CO₂ capture technology. The cement producer started a pilot of a chemical absorption method on kiln exhaust gases at its Fujiwara plant in early 2019.
