NRMCA Senior Director, Building Innovations, Frank Mruk attended yesterday (October 1) the WS Development and Sublime System’s ribbon cutting ceremony (seen here) for the first commercial application of its low-carbon Sublime Cement™. The concrete placement is located in the indoor public space of WS Development’s One Boston Wharf, Boston's largest net-zero-carbon office building, in the Seaport district. The building is a 707,000 square feet, 17-story, mixed-use structure designed by world-renowned Henning Larsen architects of Copenhagen, Denmark. In addition to 630,000 square feet of office space leased to Amazon, One Boston Wharf Road will feature ground floor retail and a new performing arts center.
Sublime Systems has developed a breakthrough process to make low-carbon cement. The technology replaces a fossil-fuel-intensive thermal calciner process with an electrochemical process that produces low-carbon cement at ambient temperatures with renewable electricity. Sublime was started in 2020 as an offshoot of Yet-Ming Chiang's lab at MIT.
Speakers included Massachusetts Governor Maura Healy, U.S. House of Representatives member Ayanna Presley, House Rep. Richard Neal, Yanni Tsipis, senior vice president, WS Development; Robin Carnahan, administrator, General Services Administration; Andrew Mayock, White House chief sustainability officer; Jonathan Gulliver, administrator, MassDOT; Boston Mayor Michelle Wu, Kent Kunkle, vice president and general manager, Turner; Jim Carreira, technical director, Boston Sand and Gravel; Don Davies, co-founder Davies Crooks and Associates; Ben Beachy, White House special assistant to the president; Emil Ramirez, vice president and Cement Council chairman, United Steelworkers Union; Justina Gallegos, White House deputy director and Leah Ellis, co-founder and CEO, Sublime Systems.
