Draft:Ecocem

Ecocem was founded in 2000 by Irishman Donal O’Riain, who aimed to decarbonise the cement industry{{Cite news |title=Nominee: Donal Ó Riain Ecocem Materials |url=https://www.irishtimes.com/business/nominee-donal-o-riain-ecocem-materials-1.1265754 |access-date=2024-11-12 |newspaper=The Irish Times |language=en}}, which is responsible for almost 8% of all global CO2 emissions{{Cite web |title=Environmental & Ecological Impacts of Cement |url=https://ukgbc.org/our-work/topics/embodied-ecological-impacts/cement/ |access-date=2024-11-12 |website=UKGBC |language=en-GB}}. In 1969, O'Riain graduated from University College Dublin with a degree in Electrical Engineering and in 2014 was awarded the UCD Alumni Engineering Award in recognition of his achievements in carbon-neutral construction{{Cite web |title=DONAL O'RIAIN |url=https://alumni.ucd.ie/awards/awardee/donal-oriain/ |access-date=2024-11-14 |website=UCD Alumni Awards |language=en-GB}}. His first job was as an engineer in ESB.

Prior to founding Ecocem, O’Riain ran his own consultancy business which specialised in cementitious materials and previously held senior management positions in KPMG, CRH plc{{Cite web |date=2018-12-13 |title=Boss puts Ecocem in mix as he helps cement industry go green |url=https://www.independent.ie/business/irish/boss-puts-ecocem-in-mix-as-he-helps-cement-industry-go-green/37620757.html |access-date=2024-11-12 |website=Irish Independent |language=en}} and Steetley/Redland plc. After the company was formed in 2000, Ecocem built its first plant in The Netherlands in 2002 with a capacity of 350,000tpa{{Cite web |date=2022-03-14 |title=Ecocem: supporting Europe's Green deal |url=https://www.cemnet.com/Articles/story/172281/ecocem-supporting-europe-s-green-deal.html |access-date=2024-11-12 |website=International Cement Review}}. The following year, Ecocem opened a second plant in Dublin, Ireland{{Cite news |title=Irish plant to make pollution-free cement |url=https://www.irishtimes.com/business/irish-plant-to-make-pollution-free-cement-1.366022 |access-date=2024-11-12 |newspaper=The Irish Times |language=en}}.

In 2007, Saint Gobain, invested in Ecocem by purchasing a 30 per cent share{{Cite web |last=staff |first=Global Concrete |date=2023-07-13 |title=Ecocem to supply ACT alternative cement to POINT.P |url=https://global-concrete.com/news/item/410-ecocem-to-supply-act-alternative-cement-to-point-p |access-date=2024-11-12 |website=global-concrete.com}}. Ecocem then also formed a joint venture with ArcelorMittal, the world’s second largest steel producer and Europes biggest{{Cite news |last1=Alim |first1=Arjun Neil |last2=Pfeifer |first2=Sylvia |date=2024-06-04 |title=Europe's steelmakers risk missing climate targets despite billions in subsidies |url=https://www.ft.com/content/a3c4862e-6f32-4eb5-a316-2d8ef13096d6 |access-date=2024-11-12 |work=Financial Times}}, to establish Ecocem France, which is managed by Ecocem.

The joint venture company went on to open its first French plant in 2009 co-located at an Arcelor Mittal site in Fos-sur-Mer, near the city of Marseille{{Cite news |title=Ecocem in €27m factory venture with ArcelorMittal |url=https://www.irishtimes.com/business/ecocem-in-27m-factory-venture-with-arcelormittal-1.987068 |access-date=2024-11-12 |newspaper=The Irish Times |language=en}}.

In 2014, Ecocem formalised its innovation-focused approach with the establishment of an Innovation Programme called “Beyond Slag” to develop new uses for GGBS (Ground Granulated Blast-furnace Slag) that focused on three main areas:

• Increasing the substitution rate of GGBS within traditional cement using chemical and thermal activation
• Producing blended cements
• Developing new products

The programme also included identifying and refining alternatives to slag, given the fact that changes to steel industry manufacturing processes, and the shift from blast furnaces to electric arc furnaces, will reduce the availability of GGBS in the coming decades and change the type of byproduct produced by the steel manufacturing process. 

In 2016 and 2017, Ecocem opened import terminals in the UK at Runcorn{{Cite web |last=staff |first=Global Cement |date=2016-03-21 |title=Ecocem to open Runcorn terminal for slag cement |url=https://www.globalcement.com/news/item/4733-ecocem-to-open-runcorn-terminal-for-slag-cement |access-date=2024-11-12 |website=www.globalcement.com}} and Sheerness{{Cite web |date=2017-06-19 |title=Ecocem to capitalise on London market with second import terminal opening {{!}} Irish Building Magazine.ie {{!}} Ireland's Leading Construction News & Information Portal |url=https://irishbuildingmagazine.ie/2017/06/19/ecocem-to-capitalise-on-london-market-with-second-import-terminal-opening/ |access-date=2024-11-12 |language=en-GB}}. The company also opened a second grinding plant at Dunkirk in France in April 2018, which serves both France and the United Kingdom{{Cite web |date=2022-03-14 |title=Ecocem: supporting Europe's Green deal |url=https://www.cemnet.com/Articles/story/172281/ecocem-supporting-europe-s-green-deal.html |access-date=2024-11-12 |website=International Cement Review}}.

The following month in May 2018, it was also announced that ArcelorMittal would be increasing their stake in Ecocem France from 30% to 49%.{{Cite web |title=Steel deal: the story of Mittal's investment in Irish firm |url=https://www.businesspost.ie/more-business/steel-deal-the-story-of-mittals-investment-in-irish-firm/ |access-date=2024-11-12 |website=www.businesspost.ie |language=en-US}}

Since the creation of the joint venture nearly 20 years ago, Ecocem and ArcelorMittal have worked closely to improve the recovery of granulated blast furnace slag from ArcelorMittal’s steel mills and used it to produce low-carbon cement. This joint relationship with Ecocem France allows ArcelorMittal to develop a low carbon product from waste in line with circular economy principles.  

On the 7^th of May 2021, Ecocem announced the completion of a E22.5M equity investment by Breakthrough Energy Ventures (BEV) and Breakthrough Energy Ventures Europe (BEV-E){{Cite web |last=May |first=Akshat Rathi |date=2021-05-10 |title=Bill Gates fund adds €22.5m to Ireland's Ecocem low-carbon mix |url=https://www.irishexaminer.com/business/companies/arid-40285724.html |access-date=2024-11-12 |website=Irish Examiner |language=en}}. Breakthrough Energy Ventures is an investment fund founded by Bill Gates which finances companies that can tackle the five big challenges set out by Bill Gates in his book - “How to avoid a climate disaster”.

The deal saw Breakthrough Energy Ventures take a 10% stake in Ecocem.

Ecocem focuses heavily on Research and Innovation, the company currently has three research laboratories, two of which are Lab Collaborations with University of Paris Saclay and another with Toulouse University. Ecocem’s Research and Innovation centre is headquartered in their Centre of Excellence for Research and Innovation in Champlan, France.  

When Ecocem initially established its innovation team, founder Donal O’Riain asked the team to work closely with commercial teams to meet customers. Together they discussed customer needs and got an understanding of what was needed to innovate within the cement industry and what customers would find most helpful. As part of this process customers met materials science experts{{Cite book |last1=Bensaou |first1=Ben M. |title=Built to innovate: essential practices to wire innovating into your company's DNA |last2=Weber |first2=Karl |date=2022 |publisher=McGraw Hill Education |isbn=978-1-260-46269-2 |location=New York}}.

As part of its commitment to Research and Innovation, Ecocem currently funds six Postdoctorates, twelve PhD’s and two Masters Degrees at a number of academic institutions, including in:

• The University of Toronto
• University of Sao Paulo
• University College Dublin
• Paris-Saclay University
• University of Florence
• Technical University of Munich
• Missouri University of Science and Technology
• The Indian Institute of Technology Delhi

In 2024, Ecocem was named as an industry partner of Science Foundation Ireland{{Cite web |title=Minister O'Donovan announces SFI Industry RD&I Fellowships for 15 researchers |url=https://www.sfi.ie/research-news/news/SFI-Industry-RDI/ |access-date=2024-11-12 |website=Science Foundation Ireland |language=en}}, the programme will support placement at Ecocem for a student from Atlantic Technological University to conduct research activities into optimising Ecocem's ACT technology for Irish concrete using Irish materials.

In November 2023, Ecocem hosted a symposium which convened fourteen leading materials scientists and engineers to test its ACT low-carbon cement technology. At the event, those in attendance signed a declaration, advocating for the adoption of materials science to deliver scalable low-carbon technology to the cement and concrete industries{{Cite web |date=2023-11-15 |title=Materials scientists call for wider adoption of low-carbon cement |url=https://www.cemnet.com/News/story/175916/materials-scientists-call-for-wider-adoption-of-low-carbon-cement.html |access-date=2024-11-12 |website=International Cement Review}}.

ACT is a low-carbon cement technology that can decarbonise the production of cement by as much as 70%, while maintaining the necessary strength durability and workability required in any concrete it is used to manufacture. It does this by reducing the clinker content of cement. Clinker is the key reactive material in cement and concrete and is responsible for over 90% of emissions from the cement and the concrete it is used to make.{{Cite web |last=Bronte |date=2024-06-06 |title=The Chemistry of Clinker |url=https://carbonre.com/the-chemistry-of-clinker/#:~:text=Clinker%20production%20is%20responsible%20for%20more%20than%2090%25,responsible%20for%20around%207.2%25%20of%20global%20CO2%20emissions. |access-date=2024-11-12 |website=Carbon Re |language=en-GB}}

Reducing the amount of clinker in cement requires the substitution with alternative reactive materials also known as SCMs (Supplementary Cementitious Materials). These materials include calcined clays, natural pozzolans and various steel slags, by products of the steel manufacture process, and are widely available. ACT technology optimises the performance of SCMs and enables them to be used with more efficiency.{{Cite web |title=Wembley trial for new low carbon cement mix |url=https://www.theconstructionindex.co.uk/news/view/wembley-trial-for-new-low-carbon-cement-mix |access-date=2024-11-12 |website=www.theconstructionindex.co.uk |language=en}}

ACT can be produced at almost all existing cement plants without significant investment or modifications.{{Cite web |title=Building Ireland Magazine/ |url=https://buildingirelandmagazine.com/ecocem-and-cb-green-unveil-joint-venture/ |access-date=2024-11-12 |language=en-GB}}

ACT is the result of almost a decade of innovation focused on developing scalable, low-carbon, competitive cement technologies. It has been subject to extensive technical validation and has been successfully demonstrated in industrial trials. Ecocem expects to make ACT available commercially in 2026, starting with the French Market.  

In February of 2024, it was announced that Ecocem had obtained a European Technical Assessment for ACT{{Cite web |title=ETAssessment 23/0877 {{!}} EOTA |url=https://www.eota.eu/etassessments/17790 |access-date=2024-11-12 |website=www.eota.eu}} in a move that would provide it with a route to full CE marking and commercialisation by 2026.
