Prometheus Materials

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).

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.
