Sublime Systems is planning a $150M sustainable cement plant in Holyoke, Mass., funded in part by a U.S. Energy Dept. and Internal Revenue Service tax credit of $46M for use of renewable power.
Fortera's ReCarb technology can significantly reduce the carbon emissions of a cement plant through a proprietary process that fixes the carbon into cementitious materials during production.
Grant Quasha is the CEO of Eco Material, a leading producer and supplier of cement products using selective cementitious materials (SCMs) and other alternative material sources. The company has made significant investments in recent years to expand its supply of SCMs beyond traditional sources of waste materials produced by coal-fired power plants. Quasha spoke with ENR about the current and future prospects for alternative materials in the cement supply chain.
Boosters for a more sustainably produced cement, which slashes greenhouse gas emissions up to 40% compared to ordinary portland cement production, say the material, called limestone calcined clay cement, is the next best embodied carbon reducer for concrete since portland limestone cement.
Holcim's plan to move toward 100% renewable power at its plants is part of its pledge as a member of the U.S. Dept. of Energy's Better Climate Challenge.
