On Monday, October 21, Sublime Systems and Somernova hosted a one-of-a-kind retirement party in Somerville.  The event celebrated the retirement of a material that has defined construction for the last two centuries: ordinary portland cement (OPC).

Sublime Systems, a leader in sustainable cement technology and a proud tenant of Somernova, celebrated the 200th anniversary of the patent for OPC by bidding farewell to this high-carbon material and welcoming the future of low-carbon cement.

This event marked a pivotal moment in construction and climate innovation as we work to replace OPC, which is responsible for 8% of global CO2 emissions, with Sublime’s breakthrough alternative. Sublime’s carbon-free cement, developed at Somernova, a 7.4-acre campus for innovation and community in Somerville’s Union Square, is the first step toward transforming the industry.

The current version of Sublime’s low carbon cement is poured outside their HQ at Somernova. Sublime will continue to develop and improve the cement over time and pour subsequent patches next to it.

Somernova, owned and operated by Rafi Properties, is home to a dynamic mix of tenants including Greentown Labs, Form Energy, Aeronaut Brewing, and many more, all united by their commitment to innovation and making the world a better place.
