Low-carbon cement manufacturer to open new production plant in Massachusetts

Jan. 16, 2024
The new plant will manufacture the cement using a “true zero” approach without fossil fuels or decomposing limestone.

Sublime Systems has announced plans to open a new commercial manufacturing facility in Holyoke, Massachusetts. The company, which specializes in fossil-fuel-free drop-in replacements for traditional cement in concrete, selected the 16-acre location based in part on Holyoke’s robust hydroelectric resources. This resource will prove critical to Sublime’s fully electrified cement manufacturing process. The company was awarded a state tax credit from the Economic Development Incentive Program and local Tax Increment Financing from the City of Holyoke to offset property taxes. The facility, which is expected to begin commission in 2026, will produce tens of thousands of tons of low-carbon Sublime Cement per year. According to the company, the new plant will manufacture the cement using a “true zero” approach without fossil fuels or decomposing limestone.

In a recent quote, Sublime Systems CEO and Co-Founder Dr. Leah Ellis said, “The same qualities that made Holyoke a world-class industrial hub in the past perfectly position it to now be the home for clean tech manufacturing of the future. The Water Street site exemplifies that in its ample space, industrial zoning, access to renewable hydroelectricity, utilities, and even rail. We are grateful to the Garcia administration, City Council, and local community groups for welcoming us to Holyoke. We are committed to being a good neighbor that engages residents as we advance cement manufacturing technology that will clean up an industry that is one of today’s worst global emitters.”
