Next-Gen, Clean Cement Deployment Forges Ahead: America’s Largest General Contractors and Local Builders Partner With Sublime Systems

General Contractors Catalyze Sublime’s Creation of a Distribution Channel Partnership Program

Inspired by the consistent interest of general contractors across the country, cement technology innovator Sublime Systems is establishing a Distribution Channel Partner program that engages general contractors (GCs) in responding to customer demand for Sublime’s cutting-edge building material. The firms participating in this program thus far represent over $60 billion in annual revenues, and include firms such as Turner Construction Company, STO Building Group, DPR Construction, Suffolk, Holder Construction, Consigli Construction Co., Inc., Samet Corporation, DOC, Methuen Construction, and more.

As Sublime Distribution Channel Partners, these firms recognize the demand for made-in-America cement that lowers CO₂ while unburdening energy use, and they are organizing to make it easier to get it to market. They will establish “Sublime Deployment Ready” teams to shape pathways, such as novel procurement structures, that swiftly move Sublime Cement® from specification to construction. Sublime Systems recently secured a long-term purchase for clean cement with Microsoft, and its Distribution Channel Partner program helps ensure the construction industry can translate customer demand into successful completed projects at scale.

“The best businesses listen and respond to the demands of their customers, and that’s exactly what these GCs are doing,” said Sublime CEO and Co-Founder Dr. Leah Ellis. “Americans want next-generation made-in-America cement that is clean, energy efficient, durable, and beautiful. They want that without compromising performance, or without complexity on the jobsite. That’s the solution Sublime brings, and that’s what these GCs are mobilizing to enable for their clients.”

Scaling cement innovations from the lab to widespread use in the built environment requires thoughtful engagement of a complex, interconnected value chain. Sublime Distribution Channel Partnerships leverages the unique role of the GC in managing a range of disciplines and building consensus on the jobsite. These Sublime Distribution Channel Partners—whose collective U.S. operations cover every major region in the country—serve as a powerful, definitive source of demand for next-generation, clean Sublime Cement as an essential material for their pipeline of construction projects and for attracting new customers motivated to decarbonize and adopt innovative, made-in-America materials into their construction projects.

Sublime Systems is advancing a breakthrough electrochemical process that replaces cement’s legacy high-heat, inefficient kilns and limestone feedstock with a process that is more efficient—unleashing more energy for American consumers. Sublime’s process produces low-carbon Sublime Cement that meets ASTM C1157, the fully performance-based specification for hydraulic cement that enables the material to be specified under existing U.S. building codes. The material is more durable than legacy ordinary portland cement (OPC) and can exhibit premium qualities such as lighter color, desirable for aesthetics and reduction of urban heat island effect. Sublime is backed by global cement leaders Holcim, CRH, Amrize, and Siam Cement Group and has been deploying Sublime Cement since 2023. The Sublime Distribution Channel Partners remarked:

“Turner was the first general contractor to implement Sublime Cement® in commercial construction applications,” said Kent Kunkel, Vice President & General Manager of Turner Construction. “We secured buy-in from our clients and trade partners through careful coordination and collaboration. Advancing the use of innovative and lower-carbon materials is directly aligned with Turner’s and our customers’ goals to reduce embodied carbon and contribute to a cleaner, more sustainable built environment.”

“At STO Building Group, we know that transforming the built environment requires innovation and collaboration,” said Jennifer Taranto, Vice President of Sustainability, STO Building Group. “We’re engaging with Sublime Systems because their technology addresses one of the most urgent decarbonization challenges in our industry—concrete. By supporting the advancement of zero-carbon concrete, we aim to help accelerate the adoption of low-impact materials, align with our clients’ climate goals, and continue our commitment to building more sustainably.”

“For DPR Construction, this isn’t just about testing a new material—it’s about unlocking a new way to build. With the high volume of concrete used in advanced tech and manufacturing projects, evaluating low-carbon solutions like Sublime Cement is critical,” said John Vardaman, Advanced Technology Core Market Leader at DPR Construction. “Through our self-perform teams, we’re exploring its potential to meet performance demands and drive real, scalable change. This is exactly the kind of innovation that can move the needle for the built environment.”

“At Suffolk, we believe true progress in our industry happens when we come together to embrace innovation and rethink what’s possible,” said John Fish, Chairman and CEO of Suffolk. “Our partnership with Sublime Systems and our participation in this agreement reflects our strong commitment to redefining how America builds — by championing cutting-edge, low-carbon materials that move us closer to a more sustainable future. Collaboration like this is essential to transforming the construction industry and delivering a cleaner future for generations to come.”

“Consigli has made environmental responsibility a core part of our work, with our teams always looking for new, cutting-edge ways to build more sustainably and efficiently,” said Todd McCabe, Vice President at Consigli Construction Co., Inc. “Sublime Systems’ clean cement technology will boost Consigli’s sustainability efforts, help us better support our clients, and reinforce our commitment to building stronger, more resilient communities.”

“At Samet, our customers come first. Providing and partnering with suppliers who can deliver exceptional results through innovation and technology to lower CO₂ is part of our mission,” said Brian Hall, President, Real Estate at Samet. “We have successfully utilized Sublime Systems to deliver results for our customers, reducing carbon impacts, while delivering best in class quality, which our customers consistently expect.”

“At DOC, we believe in conducting business sustainably—across our relationships with clients, partners, and the environment,” said Joubin Hassanein, DOC President. “That commitment drives us to seek innovations that align with our values and support our partners’ long-term goals. Our collaboration with Sublime Systems represents a meaningful step toward reimagining how building materials are made and used. With more than 146 years of experience delivering complex projects across institutional, commercial, healthcare, and infrastructure sectors, we’ve seen sustainability expectations evolve firsthand. Clients today are looking for solutions that minimize environmental impact without sacrificing performance. This partnership helps us meet those expectations—delivering value while building a better future for our industry and the communities we serve.”

Customers interested in engaging with Sublime Distribution Channel Partners or contractors who wish to become a Partner themselves can learn more and connect at sublime-systems.com/build. Additional contractors are encouraged to join the program—signaling they are ready to procure and build with Sublime Cement as demand to reduce embodied carbon and adopt American-manufactured goods grows across the construction industry and the country.

About Sublime Systems

Sublime Systems is commercializing breakthrough technology to manufacture cement more energy and resource efficiently. Sublime’s electrochemical, ambient-temperature process breaks down low-value rocks and industrial wastes into its constituents: reactive cementitious ingredients and critical mineral co-products. It avoids the waste and emissions characteristic of portland cement manufacturing while producing a similar ASTM-compliant Sublime Cement® that is more durable, more consistent, and whiter in color than portland cement. Sublime was spun out of MIT by Dr. Leah Ellis and Prof. Yet-Ming Chiang, both respected experts in materials science and electrochemical systems. The company has raised funding from leading tech investors, cooperative agreements with the U.S. Department of Energy, and three of the largest cement producers in the western world: Holcim, Amrize, and CRH. It operates a Somerville, Mass.-based 250 ton-per-year pilot, is developing its first commercial factory in Holyoke, Mass., and has secured offtakes from construction industry leaders and technology companies alike.
