Carbon Negative
Cement + Concrete
- Accelerating the World’s Future to Net Zero Carbon
of the world’s total carbon emissions come from the cement & concrete industry—
And the building industry is growing equating to building a New York City every month for the next 35 years.
Despite this known carbon problem, the demand for cement & concrete continues to grow.
And, it makes sense—the construction industry is one of the largest sectors in the world, building the homes, schools, hospitals, and businesses that make modern life possible.
We need concrete, and so we need ProZERO™.
The path to building, better
With ProZERO™, we reduce concrete's carbon impact— to negative
ProZERO™ is the first carbon negative supplemental blend designed to decarbonize the built world without disrupting the cement production process that makes the world go round.
Use ProZERO™ Blend in Your Next Project
Ready Mix
ProZERO™ ready mix and flowable fill solutions range from low carbon to carbon negative to suit any sustainability objectives and project budgets with properties that are comparable or superior to traditional cement.
Manufactured Goods
Our ProZERO™ carbon negative bio-building material spans an ever-evolving array of applications, including construction blocks, pavers and wall systems.
Remove the carbon, but not the quality.
ProZERO™ supplemental blend replaces cement in a 1:1 ratio
- Properties comparable to traditional cement
- Improved finishability in ready mix applications
- Complies with industry standards
- ASTM C90 and C129
- ASTM C1157
- ACI 299R
- LCA Stage A1-A3
How do we achieve carbon negative?
Microalgae is key.
Nature inspires the way
Removes carbon
Grown in large raceway ponds, microalgae captures carbon through photosynthesis.
avoids carbon
Limestone is a key ingredient in cement. Here, limestone is organically generated, through algae biomineralization. Therefore, as compared to generating traditional cement, ProZERO™ avoids mining limestone and the heat associated with high-temperature industrial kilns.
stores carbon
Carbon negative cement replacement is generated and carbon is stored indefinitely within the final building product.
The more cement you replace, the more carbon you reduce.
The amount of cement you replace with ProZERO™ supplemental blend is entirely up to you.
We can make your cement carbon negative, or we can simply reduce your carbon.

Recent Projects
LimeLight
Placing and Finishing of Carbon Negative Exterior Concrete
Project Limelight, a partnership between the City of Boulder and the University of Colorado, is a new hotel and conference center in Boulder, Colorado. During the project, an exterior concrete slab was poured using Prometheus Materials ProZERO™ supplemental blend. Placing and finishing was conducted in collaboration with a ready-mix producer and concrete contractor.
Milestones —
- 40% replacement of the total cementitious content
- Carbon negative concrete mix design
- Batched via a ready-mix plant
- Superior finishability reported by construction firm
- Maintained integrity harsh weather and heavy equipment traffic
Low Carbon Block Spiral
Installation
Standing today in the heart of Chicago, this exhibit illustrates society’s resonance with sustainable and forward building materials. Built in 2023, this interactive spiral is a walk-through of low carbon blocks (CMUs).
Milestones —
- Low carbon blocks
- Partnership with major architectural firm
- Blocks saved over a metric ton of carbon compared to conventional concrete blocks
Interior Pour
Finishability
This pour was at construction firm’s home office. Here, carbon negative results were achieved with 40% ProZERO™ replacement of cementitious material, providing outstanding finishability.
“The finishers were able to place it, knock it down, and drag it back with fairly little effort and when floating and troweling it. They noted it was very smooth and finished, overall, excellently.”
– Construction Firm
Milestones —
- 3500 PSI interior concrete for exposed concrete polished floor
- 40% replacement of the total cementitious content
- Carbon negative concrete mix design
Pavers at Outdoor Mall
Paver Project
Pedestrian walkway made with sustainable materials for LEED certified outdoor mall. The parent company is one of largest outdoor mall companies in America.
Milestones —
- Pavers featured a light vehicle rating, integral color, and a 95% carbon reduction
- All weather performance
