It was wonderful to host you both!
Today, our Assistant of Econ. Dev. John Dyjack and I caught up with @SublimeSystems Project Dev. & Community Relations Manager @Pat_Beaudry to serve on a Tough Tech Summit panel at The Engine Accelerator with @BenDowningMA. After the panel, we toured the headquarters of Sublime Systems at Somerville, a low-carbon cement making factory currently working toward building its first commercial manufacturing facility in #Holyoke and will soon be responsible for curving massive impact on global CO 2 emissions.

Sublime Systems got its start at @MIT and hit the ground running in Somerville. Soon, they’ll expand their impact with a facility in Holyoke and dozens of new jobs. It’s a Massachusetts success story that just became even more of a reality with the first-ever use of their low-carbon cement right here in Boston’s Seaport.

In the near-term it shores up development of our first commercial plant in Holyoke, while simultaneously laying the foundation (pun intended!) for future development together of Sublime megaton plants in multiple regions once Holyoke is complete.

This collaboration includes an equity investment, a binding reservation from Holcim of the Sublime Cement™ produced out of our first commercial facility in Holyoke, MA, and commitments to co-develop future full-scale Sublime plants together once the Holyoke factory is complete.

Scale is everything when it comes to success in cement, the key ingredient in the most consumed human-made material on Earth, concrete. It requires a broad logistics and distribution footprint that companies like Holcim have already built and excel at.

We had a great time connecting with our Holyoke neighbors at Fiestas Patronales de Holyoke this past weekend!
The largest population of Puerto Ricans in the continental United States, per capita, is in Holyoke, Massachusetts, comprising 44.8% of all residents.

We applaud @ValerieFoushee and @MaxMillerOH for introducing bipartisan legislation to accelerate low-carbon cement, concrete, and asphalt as a tool for addressing climate change while boosting American manufacturing and innovation. This public sector support is essential!

The @engineventures recently raised $398M to help develop & commercialize "tough tech." The MIT-built fund backs startups working to decarbonize heavy industrial sectors like steel (Boston Metal), cement (@SublimeSystems) & even beer 🍻(@AtmosZeroSteam) canarymedia.com/articles/cli…

At Sublime we rigorously test and validate the performance of our materials. To ensure the accuracy of those results, we even test our testing methods — and we recently passed with flying colors!!

Ensuring the accuracy of our testing methods on portland cement is critical in validating the data we share around our new low-carbon Sublime Cement™. This is a testament to our product R&D team's hard work in establishing and maintaining our testing equipment and procedures.

So much has to work in parallel as we commercialize a new low-carbon cement, and things like testing and equipment maintenance are behind the scenes. Though sometimes unseen, they are essential (like cement itself!). Not unseen today! Bravo to our team doing this critical work!
