US: Solidia Technologies has partnered with Xpansic CBL Holding Group (XCHG) to develop data technology products for precise measurement of CO₂ emissions and water usage in cement production. “Digital Feedstock enables industrial consumers to seamlessly connect sustainability ambitions with procurement decisions, wholly disrupting the way the cement industry meets consumer demand for accountability,” said Solidia Technologies CEO Tom Schuler.

Solidia Technologies produces reduced-CO₂ concrete with lower-energy cement and water-free CO₂ curing.

US: Solidia Technologies has appointed Jules Kortenhorst to its board of directors. Kortenhorst is currently the chief executive officer (CEO) of the Rocky Mountain Institute (RMI). Prior to this he was the founding CEO of the European Climate Foundation (ECF) and he also served as a member of the Dutch parliament for the Christian Democratic Party.

Kortenhorst was the CEO for International Operations of ClientLogic Corporation and he worked for almost 10 years for Royal Dutch Shell, including managing director at Shell Bulgaria. He began his career as an analyst at McKinsey & Co.

He currently serves on the Energy Transition Commission and is the co-chair of the WEF Global Future Council on Energy. He also is a non-executive board member of the Energy Web Foundation and an advisory board member of Land Life Company. He holds an MBA from Harvard and a Master’s in Economics from Erasmus University, Netherlands.

US: OGCI Climate Investments has made in an investment in Solidia Technologies to support the adoption of Solidia’s patented cement and concrete technology using CO₂.

The Oil and Gas Climate Initiative (OGCI) is a chief executive officer (CEO) led initiative of 10 oil and gas companies that collaborate on action to lead the industry response to climate change. OGCI Climate Investments, its investment arm, supports the development, deployment and scale up of new technologies that are intended to reduce greenhouse gas emissions.

“We believe that Solidia Technologies’ product and process can provide a step change in lowering the greenhouse gas and water footprint of the cement and concrete industry,” said OGCI Climate Investments CEO Pratima Rangarajan.

Solidia Cement is a non-hydraulic cement composed primarily of low-lime-containing calcium silicate phases, such as wollastonite and pseudowollastonite (CaO·SiO₂) and rankinite (3CaO·2SiO₂). The setting and hardening characteristics of Solidia Cement are derived from a reaction between CO₂ and the calcium silicates. The company uses a patented process called reactive hydrothermal liquid phase densification (rHLPD) to do this. Solidia Cement is intended to be a sustainable replacement for Ordinary Portland Cement (OPC). It uses the same manufacturing process, equipment and raw materials used by the cement industry while consuming less energy and generating less greenhouse gases.

World: Lafarge has signed an agreement with Solidia Technologies to sell its low-carbon cement and CO₂-cured concrete worldwide. Under the terms of this agreement, Lafarge will have the right to commercialise the process that reduces the carbon footprint of the end-to-end process by up to 70%. The commercial launch will initially take place in some key markets in North America and in Europe for the manufacturing of concrete elements such as paving stones, roof tiles and concrete blocks.

Solidia has developed a new binder made from similar raw materials to Ordinary Portland Cement and produced in a traditional rotary kiln. It is produced at lower temperatures and through a different chemical reaction that generates less CO₂. Used afterwards in the manufacture of precast concrete, Solidia Cement hardens through the addition and absorption of CO₂ in a patented curing process that reduces the overall carbon footprint by up to 70%. Produced at traditional precast concrete manufacturing facilities, Solidia Concrete reaches full strength in less than 24 hours.

Lafarge has worked with Solidia Technologies since 2013 to industrialise this technology. In April 2014, a joint group of Lafarge and Solidia scientists confirmed the reduced carbon footprint and commercial viability of Solidia cement during a full-scale trial at Lafarge's Whitehall cement plant in the US. The cement produced has subsequently been used by a variety of pre-cast customers in North America and Europe to further validate Solidia's curing technology and to produce blocks, pavers and roof tiles for commercial testing. In December 2014, Lafarge invested in Solidia Technologies and joined Solidia's Board of Directors.

US: Solidia Technologies has reported the chemical properties, manufacture and performance qualities of a sustainable cement that can reduce the carbon footprint of cement and concrete products by up to 70%.

Solidia Cement™is made from the same raw materials and equipment as OPC, but is adaptable to a wide variety of cement formulations and production methods, offering a sustainable and performance-enhancing alternative.

Solidia Cement clinker is produced at 1200°C, approximately 250°C lower than OPC clinker. The cement is a non-hydraulic material that is composed primarily of low-lime-containing calcium silicate phases such as wollastonite / pseudowollastonite (CaO.SiO₂) and rankinite (3CaO.2SiO₂). The setting and hardening characteristics are derived from the reaction between CO₂ and the calcium silicates. During the carbonation process, calcite (CaCO₃) and silica (SiO₂) form and are responsible for the concrete strength development.

Concrete products produced with Solidia Cement are manufactured using the same mixing and forming processes as OPC-based concrete and sequester up to 300kg of CO₂/t of cement. The reduced CO₂ emissions, combined with the ability of the cement to sequester CO₂ during concrete curing, renders a CO₂ footprint (associated with both the manufacturing and use) that is reduced by up to 70%.

"For over 50 years, scientists have tried to cure concrete with CO₂ knowing the resulting product would be stronger and more stable. Solidia Technologies is the first to make this commercially viable. Our current focus is testing additional applications with an even wider variety of concrete formulations and manufacture methods to facilitate adoption across the globe," said Solidia Chief Technology Officer Nicholas DeCristofaro, who co-authored the paper with principal scientist Sada Sahu.

Solidia Concrete™will be explored in a companion paper that is due to be released in January 2014.
