Performance and carbon reduction can go hand in hand.
In a recent comparative study by GCC, ProZERO™ was evaluated alongside a range of SCMs and achieved 6,803 psi at 28 days at a 25% substitution level-with GCC citing its “solid strength performance and strong potential for mix optimization.”
The report also called ProZERO a “promising option” for projects where both performance and carbon reduction matter.
Another independent data point demonstrating what ProZERO can deliver.
Note: While ProZERO was evaluated alongside supplementary cementitious materials (SCMs) for purposes of this comparative study, ProZERO is not technically classified as an SCM.

Data centers are one of the fastest-growing sectors in construction - and one of the biggest opportunities for carbon reduction.

As AI and cloud computing drive unprecedented growth, the question isn't whether we'll build more data centers.

It's how we'll build them.

Here's how Rowan Digital Infrastructure, Suffolk Construction, and Prometheus Materials are taking up the challenge -

Excited to share that Prometheus Materials has joined NEU: An ACI Center of Excellence for Carbon Neutral Concrete as a Growth Member!

We're proud to be part of this important community dedicated to advancing low-carbon and sustainable concrete technologies across the built environment.

At Prometheus Materials, we're inspired by nature's own processes. Our ProZERO™ technology combines microalgae with a natural constituent blend to create a high-performance alternative to traditional concrete - delivering not just lower carbon emissions, but carbon-negative results.

This membership represents another important step in our mission to decarbonize concrete and help the industry build a more sustainable future.

Another successful ProZERO™ pour completed yesterday on a major data center project!
We’re proud to see our low-carbon blended-cement performing beautifully in the field - delivering high-quality, durable concrete while significantly reducing the carbon footprint of this critical infrastructure project.
Huge thanks to the entire crew and our partners for the excellent ex*****on. Many of our Prometheus Materials team members were on-site for the pour. Moments like these remind us why we do what we do.
Real progress, real projects, real results.

Announcing our new strategic partnership with Green Stream Algae

Green Stream Algae has become a strategic partner and investor in Prometheus Materials, aligning our missions and marking a major milestone in enabling the delivery of low-carbon and carbon-negative cement at commercial scale.

Through this 10+ year partnership, Green Stream Algae will serve as the exclusive supplier of microalgae and biomineral to Prometheus Materials across North and South America.

What this means for Prometheus Materials:
We’ve secured long-term supply certainty for microalgae and biomineral, two core inputs to our carbon negative, ProZERO™ technology.

What this means for the industry:
The growing demand for low-carbon and carbon-negative cement can be confidently scaled toward more sustainable construction (without disrupting existing operations or supply chains).

🚛 16 tons of ProZERO™ shipped today - heading to the East Coast!

This latest shipment will support another major project to achieve low carbon concrete with no changes to operations. Because of our concentrated carbon reducer ProZERO™️, this project is going to meet their carbon reduction goals.

This might spark debate. It does at ASTM.... Why not just use more fly ash?
It works - but it has limits.

1. ⚠️ Supply varies
2. 📈 Higher replacement levels
3. 🛠️ Finishability can suffer

ProZERO™ is a concentrated solution → Keep the cement. Lose the carbon.

05/04/2026

We’ve officially become a sales organization.

Over the past year, we’ve proven that low- and carbon-negative concrete can actually work in the real world — across multiple pours, partners, and applications.

Now, demand is catching up.

To meet it, we’ve brought on two new team members to help scale how we go to market:
Welcome to the team 👇

– David Mesko (Colorado & Wyoming): 25+ years in concrete and commercial construction, with deep experience in ready-mix and precast, managing multimillion-dollar accounts and closing complex, high-value deals.

– David Hermida (Arizona, New Mexico & West Texas): 10+ years in bulk cement sales, including supplying the largest wind farm in the Western Hemisphere and managing 400,000+ tons annually.

We’re excited to deliver reduction in GWP by implementing our concentrated carbon reducer, ProZERO™️, into more mix designs.

04/28/2026

How much ProZERO™ goes into a mix? Most ready-mix producers use 10–40% replacement, based on carbon reduction targets.

We work directly with suppliers to determine the right level.
Practical.
Measurable.
Field-ready.

Most low-carbon strategies require replacing a lot of cement. ProZERO™ doesn’t.

Even at low replacement levels: ✅5% ProZERO™ can achieve similar GWP reduction to ~25% fly ash

That means:
1. Less replacement
2. Better performance
3. A more efficient way to reduce carbon.
