SOMERVILLE, Mass. (WBZ NewsRadio) — An environmentally friendly cement company has expanded in Somerville, Mass.

The startup company Sublime Systems creates cement with an emphasis on limiting carbon emissions. Director of Operations Caymen Somerville said replacing traditional cement with low-carbon cement could make a big impact.

“Cement is responsible for about 8 percent of the world’s emissions, so if we can figure out how to make near-zero carbon cement, we could in theory eliminate 8 percent of the world’s emissions,” said Somerville.  

Sublime Systems has tripled their amount of space, putting the finishing touches on a new 30,000 square foot lab space at Rafi Properties’ Somernova campus.

“We were able to get our first pilot plant up and running at the end of 2022, so it’s a continuous pilot plant. It has the capacity of producing 250 tons of cement per year. Now as we’ve gotten that up and running, we’re proving out that technology, we’re starting to experiment other different types of processes, so we need more space to do that,” said Somerville.

Sublime Systems is also moving ahead with plans to build a low-carbon cement factory in Holyoke, Mass.
