Germany: HeidelbergCement has published its sustainability report for 2019. The building materials producer says it decreased its specific gross CO₂ emissions per tonne of cement by 0.9% year-on-year to 622kg/t in 2019 from 628kg/t in 2018. Absolute net CO₂ emissions also fell, by 4.6% to 68.4Mt from 71.7Mt. Indirect CO₂ emission grew by 4.8% to 4.4Mt from 4.2Mt, though energy consumption in cement production fell by 3.5% to 364,000TJ from 377,000TJ.

HeidelbergCement chair Dominic von Achten said, “We have declared our express commitment to the United Nations (UN) Sustainable Development Goals. In particular, we will continue to intensify our commitment to tackling climate change in the coming years.”

France: LafargeHolcim France has said that all bagged cement will now bear a 360Score CO₂ emissions reduction rating, “to allow traders, artisans and homebuilders to know the precise carbon impact of their cement.” The rating, between ’A’ and ’D,’ corresponds to the factor of CO₂ compared to CEM-I Ordinary Portland Cement (OPC). ’A’ Class cement produces 75% – 100% less CO₂, while ’D’ class cement produces 0% – 25% less.

LafargeHolcim France chief executive officer (CEO) François Petry said, “By applying the 360Score rating scale to our bags of cements, we are continuing to implement our Lafarge 360 approach, which consists in supporting all builders to build in a more responsible manner.”

Austria: Lafarge Zementwerke, OMV, Verbund and Borealis have signed a memorandum of understanding (MOU) for the joint planning and construction of a full-scale plant by 2030 to capture CO₂ and process it into synthetic fuels, plastics or other chemicals. As part of the ‘Carbon2ProductAustria’ (C2PAT) project the companies intend to build the unit at the integrated Mannersdorf cement plant and capture all of the 0.7Mt/yr of CO₂ emitted.

"We are committed to leading the industry in reducing carbon emissions and shifting towards low-carbon construction. We have worked consistently and successfully on the reduction of the CO₂ footprint of our cement plants, products and solutions. Ultimately, CO₂-neutral cement production can only be possible with the implementation of breakthrough technologies, like carbon capture, which is why we have great expectations for the C2PAT project", said Lafarge’s local chief executive officer (CEO) José Antonio Primo.

The project aims to use hydrogen produced by Verbund to allow OMV to transform the captured CO₂ into a range of olefins, fuels and plastics. Borealis would then use some of these products as a feedstock to manufacture plastics. However, the companies say that, “taking the next steps towards a Zero CO₂ economy will require the right financial as well as favourable regulatory framework conditions. The success of C2PAT will largely depend on whether the right financial and regulatory framework conditions are created both at the European Union and Austrian national level.”

The joint project is designed in three phases. In phase one, the partners are currently evaluating and developing a joint strategy for project development, business modelling and process engineering. Based on the results of phase one, a cluster of industrial pilot plants in the Eastern part of Austria could be technically developed and built in the mid-2020s in phase two. Phase three entails building a full scale CO₂ capture and utilisation unit at a cement plant.

Lafarge Zementwerke is the Austrian subsidiary of building materials manufacturer LafargeHolcim. OMV produces and markets oil and gas, energy and other petrochemical products. Verbund is an Austrian-based electricity generator, with a focus on hydroelectric power. Borealis is a chemical company and a producer of polyolefins, base chemicals and fertilisers.

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.

France: CRH subsidiary EQIOM has announced a 9000t/yr reduction in its transport-related CO₂ emissions, down by 5% to 171,000t/yr for the past three years from 180,000t in 2017. It achieved the reduction through its commitment to the FRET21 initiative, a sustainable development strategy of the Agence de l’Environnement et de la Maîtrise de l’Énergie (ADEME) and Association des Utilisateurs de Transport de Fret (AFAT).

The initiative is based on CO₂ reduction around four key activities: loading rate; distance travelled; means of transport; and responsible purchasing. EQIOM launched five initiatives, including increasing laden returns of trucks to reduce empty transport to 28%, commissioning four new natural gas and bioethanol-powered vehicles and increasing rail freight to 89%.

EQIOM logistics manager Jérôme Becamel said, "As in the rest of the country, our transport activity has been impacted by the social situation, particularly strikes on the roads and in the railways. However, we are delighted with the results obtained for this first challenge even if we were unable to reach our ambitions 100%. We are only more motivated and we will be stepping up our efforts over the next three years.”

Norway: Norcem, a subsidiary of HeidelbergCement, has signed an agreement with Aker Solutions to order a CO₂ capture, liquification and intermediate storage plant at its integrated Brevik cement plant. The final decision for the project depends on funding from the Norwegian government, which is expected to approve the unit in its national budget for 2021.

The project will use Aker Solutions’ Advanced Carbon Capture (ACC) technology and its S26 amine solvent. Once complete the unit will capture 0.4Mt/yr of CO₂. This will be transported to the Northern Lights project for permanent storage offshore beneath the North Sea.

Switzerland/US: LafargeHolcim has announced the extension of its partnership with Solidia Technologies to mid-2020. Cash News has reported that the partnership, which has seen a 30% reduction in LafargeHolcim’s overall CO₂ emissions since its formation in mid-2013, aims to achieve a 70% reduction in the producer’s carbon footprint.

Belgium: Cembureau, the European Cement Association, has published its new Carbon Neutrality Roadmap, setting out its ambition to reach net zero emissions along the cement and concrete value chain by 2050. The roadmap examines how CO₂ emissions can be reduced at each stage of the value chain – clinker, cement, concrete, construction and (re)carbonation – to achieve zero net emissions by 2050. It quantifies the role of each technology in providing CO₂ emissions savings, making concrete political and technical recommendations to support this objective.

“As Europe begins its green recovery, the significance of this moment for our sector is huge. This is our response to the EU Green Deal – we have a plan and are ready to make the leap.” said Raoul de Parisot, president of Cembureau. The association has identified areas where it says it requires decisive political action from the European Union (EU). These include: the development of a pan-European CO₂ transportation and storage network; action on circular economy to support the use of non-recyclable waste and biomass waste in cement production; policies to reduce European building’s CO₂ footprint, based on a life-cycle approach, that incentivise the market uptake of low-carbon cements; a ‘level’ playing field on carbon, regulatory certainty and an industrial transformation agenda.

Cembureau says it aspires to be in line with the Paris Agreement’s two degrees scenario, reducing CO₂ emissions by 30% for cement and 40% down the value chain. Its chief executive Koen Coppenholle added that, “Carbon neutrality along our full value-chain will be a massive effort, but we are confident we can achieve it. Our sector has made significant progress and, with the right tools and support from the EU, we can go much further.”

Norway: Private accreditation body DNVGL has certified Aker Solutions’ 400,000t/yr carbon capture and storage (CCS) system installation at Germany-based HeidelbergCement subsidiary Norcem’s 1.2Mt/yr integrated Brevik plant in Telemark as safe. HeidelbergCement Northern Europe director of sustainability and alternative fuels Per Brevik said, “The promising results from pilot testing in Brevik give us confidence that realisation of the full-scale capture plant will be successful. We trust that the project risk related to novel technology elements is low.”

Following an 18-month test of the partial installation, the certification ensures that the full-scale project will receive government funding.

Hungary: Italy-based Entsorga has completed the installation of an automated alternative fuel (AF) line at a Hungarian cement plant.The upgrade consists of an Entsorga Spider crane and Pelican power system which will be able to maintain a continuous feed to the plant’s calcination system 24 hours a day.

Entsorga CEO Francesco Galanzino said, “Bringing a commission to a successful conclusion in the middle of the maximum intensity period of the coronavirus crisis has been a great satisfaction. The cement plant will make significant savings in CO₂ emissions.”
