If you still feel that this subject is worthy of inclusion in Wikipedia, please rewrite your submission to comply with these policies. Declined by AirshipJungleman29 8 months ago.

Ecocem

Ecocem is an Irish multinational company specializing in the development and production of low-carbon cement. Founded in 2000, the company focuses on reducing CO₂ emissions in the cement and construction industries by utilizing supplementary cementitious materials.

Overview

Ecocem operates production plants and import terminals in Ireland, France, the UK, and the Netherlands.^[1]. The company is headquartered in Dublin, Ireland, and supplies its products in multiple European markets, including Germany, Belgium, Italy, and Sweden.

Ecocem's technologies aim to reduce the clinker content in cement, which is responsible for approximately 95% of cement-related CO₂ emissions.^[2] The company claims its products have prevented over 18 million tonnes of CO₂ emissions as of 2024.^[3]

History

Ecocem was founded in 2000 by Donal O’Riain, who previously held senior management positions in KPMG, CRH plc^[4] and Steetley/Redland plc. O’Riain graduated from University College Dublin (UCD) with a degree in electrical engineering and later received the UCD Alumni Engineering Award for his contributions to sustainable construction^[5].

The company’s first production facility opened in the Netherlands in 2002^[6], followed by a plant in Dublin in 2003.^[7] In 2007, Saint-Gobain acquired a 30% stake in Ecocem.^[8] The same year, Ecocem formed a joint venture with ArcelorMittal, establishing Ecocem France, which opened a plant in Fos-sur-Mer in 2009.^[9]

Expansion continued in with import terminals in The UK in Runcorn (2016)^[10] and Sheerness 2017.^[11] A second French plant was opened in 2018 in Dunkirk (2018).^[12] In 2021, Breakthrough Energy Ventures, a climate-focused investment fund founded by Bill Gates, invested €22.5 million in Ecocem for a 10% stake.^[13]

Technologies

ACT (Advanced Cement Technology)

Launched in 2022, ACT is a low-carbon cement technology designed to reduce emissions by up to 70% while maintaining performance.^[14] It optimizes the use of SCMs like calcined clays, natural pozzolans and various steel slags. ACT received a European Technical Assessment (ETA) in 2024.^[15]

Partners for ACT trials and development include Cemex France^[16], Bouygues Construction^[17], Titan Group^[18] and CB Greene^[19]

GGBS (Ground Granulated Blast-Furnace Slag)

Ecocem’s GGBS is a byproduct of steel production. It complies with EU standard EN 15167-1:2006 and has a carbon footprint of 42 kg CO₂ per tonne.^[20]

Other Products

• Ecocem Ultra: An alkali-activated binder with an 80 kg CO₂ per tonne footprint, used in projects like the Grand Paris Express.^[21]
• Ecocem Superfine: A slag-based additive for high-performance concrete, with a footprint of 32 kg CO₂ per tonne.^[22]
• CEM VI & CEM III/A: Low-carbon cements with varying slag content for different construction applications.^[23][24]

Research and Innovation

Ecocem collaborates with academic institutions, including:

• 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
• The University of Toulouse
• The Eindhoven University of Technology
• University of California, Davis^[25]

The company funds multiple postdoctoral and PhD research programs and operates a research center in France.^[26]

In 2024, Ecocem partnered with Science Foundation Ireland to optimize ACT technology for Irish materials.^[27]

Notable Projects

Ecocem’s products have been used in:

• Tottenham Hotspur Stadium (UK): Reduced CO₂ emissions in precast concrete.^[28]
• Paris 2024 Olympics: Supplied low-carbon cement for the athletes' village, media village and center porte de la chapelle.^[29]
• Grand Paris Express: Pilot use of Ecocem Ultra in metro construction.^[30] 
• HS2 Railway (UK): Estimated CO₂ savings of 161,162. ^[31]
• Aviva Stadium (Ireland): 4,000 tonnes of CO₂ saved.^[32]
