Not too long ago, key gamers within the cement trade have introduced plans and are available public with a devoted dedication to carbon neutrality. Of observe, LafargeHolcim, the Portland Cement Affiliation, in addition to the Worldwide Cement Assessment – a web site devoted to the cement trade primarily based in the UK.
LafargeHolcim’s climate pledge contains:
- scale back direct CO2 emissions from the actions of a corporation underneath its management to a goal in step with a internet zero pathway,
- be carbon-neutral in oblique emissions from electrical energy bought and utilized by a corporation
- and scale back all different oblique emissions from actions of the group from sources that they don’t personal or management – considerably, concentrating on a 50% discount
The Portland Cement Affiliation (PCA), additionally got here ahead with its plans to develop a roadmap by the tip of subsequent yr (2021) “to facilitate its member firms reaching carbon neutrality throughout the concrete worth chain by 2050.” Within the announcement, the PCA explains that “the roadmap will determine tips on how to deal with the challenges that stand in the best way of driving down emissions to realize carbon neutrality, equivalent to creating superior applied sciences to scale back power consumption, and creating and adopting laws to permit for such applied sciences.”
On September 21-24, the digital convention “Decarbonising the cement trade – pathways to a sustainable future,” organized by Worldwide Cement Assessment / CemNet.com. The next is a report of the happenings of that occasion. Printed beneath with permission.

Achievements and pledges
Within the opening presentation, Mahendra Singhi, CEO of Dalmia Bharat Ltd (India), offered an inspirational begin to the convention as he laid out the pressing want for decarbonisation and making the trade extra sustainable. He emphasised the significance of selecting the best know-how on this journey however was assured on the advantages for the trade: “Quickly, there’ll solely be an acceptance for zero carbon transition as soon as the advantages of shifting right into a decarbonisation journey begin unfolding for the businesses who’ve proactively taken the steps.”
Following on, Dinah McLeod, chief government of the International Cement and Concrete Affiliation (GCCA), highlighted the necessity to place concrete because the sustainable materials of alternative, supported by the organisation’s pledge to realize carbon-neutral concrete by 2050. Moreover, she acknowledged that innovation is completely key to result in an trade match for the long run, emphasising the essential position to be performed by Innovandi, the brand new cement and concrete analysis community, arrange by the affiliation.
Magali Anderson, chief sustainability officer of LafargeHolcim (Switzerland), introduced the corporate’s international technique for decarbonisation and confirmed its Web Zero Pledge, validated by the Science Based mostly Targets initiative. New intermediate targets will see LafargeHolcim search to decrease its CO2 depth to 475kg internet CO2/t of cementitious materials by 2030.
Ms. Anderson additionally highlighted the significance of the round financial system: “Actually our pledge as we speak is about local weather and I’m speaking loads about CO2, however I believe the place now we have implausible alternatives is on the round aspect [….] We actually want to indicate the world we’re extra round. Concrete is a 100 per cent round product and I’m undecided many individuals learn about that. On the finish of the lifetime of a constructing, as soon as we demolish it we will reuse and put it straight in our cement or in our concrete.”
Sustainable applied sciences
Throughout the convention, cement producers and tools suppliers shared examples of the applying of sustainable applied sciences in cement crops. Mauricio Giraldo of Argos Cement in Colombia defined how his firm had considerably improved various gas (AF) substitution in its Colombian crops. As well as, Stanislaw Sobczyk of LafargeHolcim in Poland showcased best-in-class AF utilisation on the firm’s Kujawy plant, the place substitution charges are near 90 per cent.
Clinker discount was additionally explored intimately with two displays focussing on the applied sciences for calcined clay. Steven Miller, FLSmidth (Denmark), and Luiz Felipe de Pinho, Dynamis (Brazil), each showcased state-of-the-art applied sciences on this rising space and case research from latest tasks.
Peter Hoddinott adopted by taking a look at a brand new kind of pozzolan-based cement invented by Vladimir Ronin of EMC. This ‘energetically modified cement’ is an ultra-low CO2 cement primarily based on globally accessible minerals. Mr Hoddinott argued that “CO2 emissions discount by clinker substitution will attain 35 per cent, however simply when wanted most, slag and fly ash availability are in decline.” EMC gives a gorgeous and new various.
From India, Atul Priyadarshi of Bharathi Cement, a part of Vicat Group, shared an account of its renewable power journey together with WHR and solar energy tasks.
Pathways to enchancment
Power and course of optimisation additionally stay a part of the answer to decrease CO2 emissions, with a number of displays figuring out confirmed applied sciences that may now be deployed in crops. Jens Breidenbach, KHD (Germany) revealed how upgrading present ball mills with highly-efficient curler press-based grinding circuits can present important features in CO2 discount for cement firms.
Digitalisation of the trade can be offering additional alternatives to enhance the trade’s environmental efficiency by higher information assortment and decision-making. Javier García Sedano, CEO of Spain-based Optimitive, focussed on the applying of synthetic intelligence (AI) within the cement manufacturing course of.
“We suggest to use synthetic intelligence linked in real-time to the cement course of, studying the information, studying from that information and making use of optimum settings always in automatic-pilot mode in closed loop or open loop and on this means reaching optimum efficiency always,” Mr García Sedano mentioned.
Dr Paul Flachskampf of INFORM (Germany) emphasised the significance of CO2 discount efforts in logistics and transport, mentioning that the supply of two truck a great deal of cement will generate emissions equal to the CO2 launched in producing 1t of cement. Optimisation of logistics is due to this fact an important space of focus for all cement firms, and might be achieved most efficiently through the use of AI and machine studying software program to optimise truck fleets.
A glance into the long run
Audio system offered quite a lot of insights into the trade’s dedication to enhance its sustainability document going ahead.
Jim O’Brien of Jim O’Brien CSR (Eire) examined whether or not the cement trade was certainly strolling the sustainability discuss. He concluded that, whereas nice progress had been made, advances had slowed in recent times and the tempo now wants to select up. There stays room for enchancment, significantly within the space of security regardless of latest advances.
Tony Hadley, THAA (EU), urged a shift in tradition from complacency and compliance to management in industrial excellence. The trade must be totally carbon-reformed by 2040 – not 2050, he argued. Furthermore, these firms that fail to indicate they’re shifting in the best course can be penalised by traders and society.
Finally, the trade wants extra analysis, pilot- and industrial-scale trials to push forward in decarbonising its operations. Communication with all stakeholders and the creation of alliances with know-how suppliers, analysis institutes and universities can be key in fostering innovation and reaching the profitable implementation of those new applied sciences. That is significantly true within the space of carbon seize, storage and reuse, one of the vital essential pathways to significant large-scale carbon discount.
Jan Theulen of HeidelbergCement (Germany) outlined the corporate’s carbon neutrality technique and the half performed by its cutting-edge carbon seize know-how analysis and investments, together with the LEILAC2 challenge.
Dr Laury Barnes-Davin of Vicat (France) knowledgeable the viewers in regards to the firm’s two cutting-edge modern tasks: combination manufacturing by carbonation of kiln mud utilizing Carbon8 know-how and the carbonation of recycled concrete aggregates utilizing cement flue fuel throughout the framework of France’s Nationwide Challenge, Fastcarb.
In the meantime, Mirko Weber and Joseph Kitzweger of LafargeHolcim shone a highlight on Austria’s C2PAT initiative, which goals to seize CO2 from LafargeHolcim’s Mannersdorf cement plant in Austria and course of it with renewable-based hydrogen to provide hydrocarbons for merchandise equivalent to plastics or kerosene.
Funding can be key within the implementation of the trade’s initiatives to scale back its carbon footprint – a reality not misplaced by Eric Trusiewicz, Breakthrough Power Ventures (USA and Spain), who defined the curiosity of cleantech enterprise capital in investing in low-carbon applied sciences within the cement trade.
As Mr Singhi mentioned firstly of the convention: “Now it’s time for cement firms and its professionals to dream large, purpose large, plan large and create a roadmap for carbon-free cement. Finally now we have to transform our sector from gray to inexperienced.”
