WS Development and Sublime Systems have applied low-carbon Sublime Cement, manufactured by Sublime Systems, in the indoor public space of WS Development’s One Boston Wharf, a new net-zero-carbon office building.
Sublime Systems is developing a method of avoiding CO2 from cement-making, which currently accounts for 8% of global CO2 emissions, according to the company. Sublime’s “true-zero” manufacturing technology fully avoids traditional cement’s major emissions sources, including limestone feedstock and fossil-fueled kilns. Instead, the company uses electrochemistry to extract reactive cementitious ingredients from non-carbonate materials.
