We have a third party verified and published EPD
The lowest recorded Global Warming Impact (GWP) of any SCM!
GWP Comparison of Zeolite vs. Other Common SCMs:
- Concrete Grade Clinoptilolite Zeolite from Zeolite Composites: 32.3 kg CO₂-eq/ton
- Calcined Clay: ~48 kg CO₂-eq/ton
- Fly Ash: ~65 kg CO₂-eq/ton
- Slag: ~75 kg CO₂-eq/ton
NOTE: GWP of Ordinary Portland Cement (OPC) ~922 kg CO₂-eq/ton
1 ton of OPC replaced with our SCM
results in 0.922 tons of CO₂ prevented!
We are proud to be the first SCM material supplier to have a methodology accepted and listed by Climate Action Reserve (CAR).
Clinoptilolite Zeolite: The World's SUPER SCM!
Made in the U.S.A.
Our clinoptilolite zeolite (Zeolite) is a naturally occurring Supplementary Cementitious Material (SCM) with pozzolanic properties. Unlike other SCM material alternatives, zeolite does not require any heat processing and is therefore better for the environment. Zeolite is also cheaper than other SCM material alternatives and it improves the strength and reliability of concrete compared to concrete made with OPC.
Zeolite, a naturally occurring and abundant pozzolan is the most eco-friendly alternative SCM to OPC and has the smallest overall NET carbon footprint and the smallest total impact on the environment.
Our Zeolite-Concrete Composite alternative can benefit emerging economies and the planet. Zeolite is a transformative SCM material that is affordable and can scale globally rather than hypothetical replacements for cement that are not yet affordable or ready to commercialize around the globe.
Zeolite DOES NOT Require Heat Treatment and has the Smallest NET Carbon Footprint
Our SCM decreases reliance on carbon-intensive Ordinary Portland Cement (OPC) and is simply the lowest carbon footprint alternative to replace OPC, furnace slag, and fly ash.
Innovative Science and Technology
Our Clinoptilolite Zeolite Naturally Contains the Ideal Amounts of Silica (Si), Alumina (Al) and Calcium (Ca) for Replacement of Portland Cement in Concrete
- Si:Al Ratio is Very Important
- Higher = Better
- Clinoptilolite Zeolite from Zeolite Composites is Higher Reactivity than Fly Ash or Furnace Slag

Calcium Hydroxide Crystals
We are conducting all of our testing and development in accordance with ASTM C595 and ASTM C1157.
Showing compliance with ASTM C595 and ASTM C1157 is important for our low carbon concrete implementation strategy and acceptance by the commercial construction industry.
Other than water, concrete is the most used material on the planet.
By one estimate, the world will add 2 trillion square feet of buildings by 2060 - the equivalent of putting up another New York City every month for the next 40 years.
Even small changes to the formulation of concrete with lower carbon footprint ingredients, such as zeolite, can help lower CO₂ emissions resulting from cement and concrete production.
A major component (ingredient) of concrete is cement. The cement industry is one of the main producers of carbon dioxide (CO₂), a potent greenhouse gas contributing to climate change.
Concrete is responsible for up to 10% of total CO₂ emissions.
Cement manufacturing releases CO₂ in the atmosphere when calcium carbonate is heated, producing lime and CO₂.
To tackle the world’s climate crisis and achieve net-zero CO₂ emissions by 2050, we must significantly reduce CO₂ emissions from concrete.
Scalable, affordable, and Sustainable Product Design
Zeolite Composites, LLC in collaboration with C-Crete Technologies, Heidelberg, and Don Davies
First ever 20-ton 100% zeolite concrete (zeolite + activator from C-Crete) pour with 100% OPC replacement:
- Commercial project located in Seattle, WA
- More than 5,000 psi in compressive strength
- Flows and pumps like conventional concrete
- Meets industry standards set by ASTM International for mechanical and durability properties
- Cost-parity with traditional concrete made with OPC
"What is exciting about this pour are the additional implications of using zeolite," says Donald Davies, owner of the Seattle building and chair of Building Transparency, a nonprofit organization dedicated to enabling the building industry to address embodied carbon's role in climate change. "This is a potentially new feedstock material that is not in the market today as a supplementary or in this case a fully alternative cementitious material [SCM or fully ACM]. This was a field trial of a new material to show what is possible. It was batched from a ready-mix truck, pumped and finished using normal construction procedures on the site."
The zeolite from Zeolite Composites is uniquely suited as an alternative SCM material for the replacement of OPC in traditional concrete materials and products because of its naturally occurring silica, alumina, and other key elements in the right amounts and ratios important for OPC replacement.
