HeidelbergCement released their sustainability report for 2019 this week. Every large cement producer publishes one but this one is worth checking out because of the company’s ambition to become CO₂ neutral. Other companies are heading the same way but few of them have such developed and public plans.

Sustainability reports are often a hodgepodge of non-financial reporting bringing together environment, health and safety, community and other topics. Multinational companies cover a wide range of jurisdictions and combining reporting in these kinds of fields can be beneficial. Typically they are members of various bodies like the Global Reporting Initiative (GRI) or the Global Cement & Concrete Association (GCCA) that give various levels of conformity between reports. Yet, the wider focus of sustainability reports gives companies a chance to promote what they are doing well, away from balance sheets.

One highlight of HeidelbergCement’s report is its progress towards reducing its specific CO₂ emissions per tonne of cement and its recognition by the Science Based Targets (SBT) initiative towards this goal. So far it has achieved a reduction of around 22% from 1990 levels to 599kg CO₂/t (net) with a target of a 30% reduction or 520kg CO₂/t by 2030. There is a lot more going on in the report but it’s led by the vision, ‘to offer CO₂-neutral concrete by 2050 at the latest.’ It plans to achieve this by increasing the proportion of alternative CO2-neutral raw materials and fuels, developing lower clinker cement types and capturing and utilising CO₂ emissions. A focus on concrete is worth noting given the pivot by building materials manufactures towards concrete in recent years.

Back in the present, HeidelbergCement is roughly in the middle of the pack of major European multinational cement producers with its specific CO₂ emissions for cement in 2019. LafargeHolcim reported 561kg CO₂/t and Cemex reported 622kg CO₂/t. This is a bit of a moving target since corporate acquisitions and divestments can change both the starting point and the apparent current progress. HeidelbergCement’s acquisition of Italcementi in 2017 or CRH’s purchase of Ash Grove did exactly that. The other thing to consider is that these companies manufacture a lot of cement. The actual gross CO₂ emissions from a multinational cement producer are immense. LafargeHolcim, one of the world’s largest multinational producers, emitted 113Mt of CO₂ in 2019 from process and fuel sources whilst making cement. To put that into context, estimates for total global CO₂ emissions range from 33 – 36Gt for 2019. The cement industry’s entire share was estimated by the International Energy Agency (IEA) to be 4.1Gt in 2018.

Where this sustainability report starts to become really interesting is where it talks about CO₂ capture and utilisation. Its plans in this department are more mature than many of its competitors with various initiatives at different levels of development, mostly in Europe. Norcem, its Norwegian subsidiary, recently signed an agreement with Aker Solutions to order a CO₂ capture, liquification and intermediate storage plant at its integrated Brevik cement plant. The deal is dependent on government support but it’s a serious proposal. As reported previously from the Innovation in Industrial Carbon Capture Conference 2020, HeidelbergCement is actively preparing to hook up with CO₂ transport and storage infrastructure. The driver is CO₂ pricing from initiatives like the European Union (EU) Emissions Trading Scheme (ETS). With the EU preparing for the next phase of the ETS and talk of the European Green Deal gathering pace, before the coronavirus outbreak at least, CO₂ prices in Europe look set to rise. HeidelbergCement is positioning itself to benefit from being the first major cement producer to head into CO₂ capture and storage/utilisation with a variety of methods intended for different CO₂ prices and regional requirements.

HeidelbergCement doesn’t mention the coronavirus pandemic in its latest sustainability report. The report covers 2019 after all, before all of this happened. These reports do include health and safety information of employees, so this may be something to look out for next year. However, Cemex did mention the coronavirus in relation to its climate action plans this week. Essentially it wants to maintain its plans as a ‘fundamental component’ of its efforts to recover from the health crisis. This chimes with media talk around so-called ‘green-led’ government-backed relief programmes. Governments are the ones who are likely to be handing out the money, probably in the form of infrastructure projects. So it’s the perfect opportunity for them to encourage change from the companies bidding for this funding. Sustainability reports and the information behind them will be a useful tool in accessing this cash.

Germany: Schwenk Zement has announced plans for the production of sustainable aviation fuel (SAF) from cement kiln CO₂ emissions. The World Ethanol and Biofuels Report has reported that Schwenk Zement’s integrated 1.0Mt/yr Allmendingen, Baden-Württemberg plant will receive a pilot SAF plant in late 2020.

Japan: Taiheiyo Cement has partnered with JFE Steel and the Global Institute for Environmental Technology to develop a carbon capture and storage system. The system will use wet alkaline earth metals extracted from steel slag to produce carbonates from exhaust gases at cement and steel plants. The partners are investigating the possibility of using these carbonates, specifically calcium carbonate and magnesium carbonate, as additives in cement production at Taiheiyo Cement’s plants. Taiheiyo Cement president Masafumi Shigehara said, “With the effects of climate change becoming apparent both in Japan and overseas, the importance of global warming counter-measures is increasing.”

Europe: Australia-based Calix has announced that construction will begin on its second low emissions intensity lime and cement (Leilac) carbon capture and storage (CCS) installation at a ‘European cement plant’ on 7 April 2020. ASX ComNews has reported that collaborators on the project, which has received Euro16m under the EU’s Horizon 2020 grant scheme, are Portugal-based Cimpor, Germany-based HeidelbergCement, Germany and France-based energy companies Ingenieurbüro-Kühlerbau-Neustadt (IKN) and Engie and Belgium-based minerals and lime company Lhoist. Calix has said that the 100,000t/yr process emissions capture facility will be operational in late 2024.
The company has appointed Emma Bowring Leilac-2 project leader.

The first Leilac installation was completed at HeidelbergCement’s 1.5Mt/yr integrated Lixhe plant in Belgium’s Limburg province in mid-2019.

Germany: HeidelbergCement’s profit was Euro1.24bn in 2019, down by 3.4% from Euro1.23bn in 2018. Its revenue grew by 4.3% to Euro18.9bn from Euro18.1bn. HeidelbergCement says that it reduced its specific net CO₂ emissions by 1.5% year-on-year to 590kg/t from 599kg/t in 2018 and ‘intensified its research and development (R&D) efforts on carbon capture and utilisation/storage (CCU/S)’ in every operating region globally.

The group announced a year-on-year increase in volumes in the first two months of 2020, with all but three of its plants (HeidelbergCement subsidiary Italcementi’s 2.8Mt/yr Calusco plant, 2.5Mt/yr Rezzato plant and 0.6Mt/yr Tavernola plant in Lombardy region, Italy) still operating through the coronavirus pandemic, though it noted that construction is slowing in the US, Australia and Western Europe due to the outbreak.

HeidelbergCement cancelled its 7 May 2020 annual general meeting (AGM) ‘due to the spread of the coronavirus.’

UK: Germany-based HeidelbergCement’s subsidiary Hanson Cement will be the subject of a study in the use of biomass and hydrogen fuels coordinated by the Mineral Products Association (MPA). The Department for Business, Energy and Industrial Strategy is funding the Euro3.81m study, the results of which it says will be shared across the cement industry. HeidelbergCement CEO Dominik von Achten said, "In addition to our activities in the field of carbon capture, use and storage (CCUS), this project is an important step towards realising our vision of carbon-neutral concrete by 2050.”

Canada: McInnis Cement, Écotech Québec and the Gaspésie Cleantech Hub, in collaboration with the Québec Ministère de l’Économie et de l’Innovation, have launched a call for innovations to identify carbon capture and utilisation technologies for the Port-Daniel-Gascons, McInnis cement plant. This call for innovations will run until May 2020 and then selected organisations will be invited to explore future options.

“From the moment the company was founded, McInnis Cement has been exploring the option of replacing some of the hydrocarbons used as fuel for the plant with locally generated residual forest biomass so as to reduce its environmental emissions,” said Maryse Tremblay, Director of Communications and Corporate Social Responsibility at McInnis Cement. She added that a study to verify the feasibility of using this type of alternative fuels is underway and that this may be followed by a pilot project.

Écotech Québec is a non-profit organisation, funded by the provincial government, which represents Québec's ‘clean’ technology cluster. It supports businesses, researchers, investors and associations to help accelerate the development, financing and commercialisation of clean technologies. The Gaspésie Cleantech Hub is an economic development organisation created to help the region increase the economic benefits of establishing the McInnis cement plant.

US: Holcim US’s 1.9Mt/yr Portland cement plant in Colorado has become the latest site to host a large-scale cement plant carbon capture and storage (CCS) study. Holcim US, in partnership withCanada-based Svante, France-based Total and US-based Occidental subsidiary Oxy Low Carbon Ventures, will install a facility designed to capture 0.73Mt/yr of CO2, which Occidental will take for safe storage underground. The study will assess the financial viability and design requirements of such an installation on a permanent basis.

Hungary: Lafarge Cement Hungary has announced plans to upgrade clinker production at its 1.0Mt/yr Kiralyagyháza integrated plant with a Euro1.79m investment in chlorine bypass technology, which uses powdered limestone to remove chlorine and one tenth of the carbon dioxide (CO₂) from gases released in clinker production, which will then be used in clinker cooling. There will be a concomitant increase in the rate of alternative fuel (AF) substitution in the plant’s kilns, with an AF fuel store expansion in early 2020 set to raise AF usage to 80% from 60%.

Germany: Four of Europe’s leading cement producers have partnered to found and operate a 100% carbon capture and storage (CCS) plant at Schwenk Zement’s 1.0Mt/yr Mergelstetten plant in southern Germany. HeidelbergCement has announced that the catch4climate project will enter operation in 2020.
