LafargeHolcim and Solidia Technologies Announce First US Commercial Expansion

7 August 2019

Chicago, IL and Piscataway, NJ, August 7, 2019 – LafargeHolcim in the US, and US start-up, Solidia Technologies® have announced the first commercial venture to supply EP Henry’s Wrightstown, New Jersey paver and block plant with a reduced CO2 cement. Over the past 6 years, the two companies have developed an innovative technology that will reduce the environmental footprint of pre-cast concrete and validate Solidia Cement™ at a commercial scale.

In 2013, the companies launched a pilot program to develop low-carbon pre-cast concrete pavers with EP Henry, a national outdoor unit concrete products manufacturer.  Based on Solidia Cement produced at the Lafarge Whitehall plant, a proprietary concrete mix design, and a specialized curing process utilizing CO2, the two companies developed a concrete that is stronger, more durable, and higher performing than traditional versions. The first commercial offerings were launched earlier this year, demonstrating improved aesthetics and product durability.

 “LafargeHolcim has long been committed to bringing innovative solutions to market, and this commercial agreement with EP Henry is an important step in showing that reducing our CO2 footprint through carbon captured products is feasible,” said Jamie Gentoso, CEO, US Cement, LafargeHolcim. “It has been incredibly rewarding to see how together, we have collaborated to move this technology from the experimental phase and into the US market as a viable product.”

“By offering their technical expertise and market intelligence, LafargeHolcim helped us eliminate barriers to adoption, leading us to this first commercial traction in the US,” said Solidia President and CEO Tom Schuler, “to expand our range of offerings, making sustainability business as usual across the global US$1 trillion concrete and US$300 billion cement markets.”

About Solidia Concrete

Solidia has developed a new binder made from raw materials similar to those in Portland cement and produced in a traditional rotary kiln. Solidia 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 (carbonation) in a patented curing process that reduces the overall carbon footprint by up to 70%.

Produced at traditional precast concrete manufacturing facilities, Solidia Concrete™ is higher performing and reaches strength in less than 24 hours, compared to 28 days for precast concrete made using Portland cement. This offers considerable energy savings and cost reductions to precast concrete manufacturers. Solidia Cement was first produced at the Lafarge Whitehall cement plant in Pennsylvania in 2014, and has since expanded production with additional runs at Whitehall and at its Pecs, Hungary plant.

The patented processes not only reduce the cement plant’s carbon emissions by up to 40%, but also use 30% less energy to make more cement with the same amount of raw material. Unlike Portland cement, Solidia Cement is cured with CO₂, not water, and EP Henry’s new paver offerings gain their performance advantages as a result of this new chemistry.
