Listen to how we solve two of the world's greatest problems with one solution.
Turning Negative Into Positive
We use multi-objective AI optimization to identify and transform previously unusable industrial waste into high-performance, carbon-negative supplementary cementitious materials (SCMs), doubling both revenue and CO₂ reduction compared to traditional mineralization methods.
How It Works
Remediate Replace Reduce
Monetizing Waste, SCMs, & Carbon
Waste Remediation
>$50/t value
Carbon-Negative SCMs
>$100/t value
Carbon Credits
>$60/t value
Harnessing AI
We build where it matters!
Using AI to design-optimize cement alternatives based on locally available industrial waste and natural materials, delivering the lowest cost and highest carbon reduction possible.
We account for thousands of physiochemical factors converting variable wastes into standardized materials with over 95% accuracy.

We Are All Bound By Nature
We may forget sometimes but humans are an animal species. No matter how complex we make society, we are still simple creatures.
We all want the best solutions to climate change for the betterment of our lives and future generations.

CONCRETE PROBLEM
United Nations data shows that more than 100 million people are projected to die prematurely this century due to climate change.
The cement/concrete industry accounts for 8% of carbon emissions, 30% of all solid waste generated, AND 40% of all raw materials extracted globally. This means millions of people will die prematurely from our industry's impact unless a meaningful solution is found.

UNITY
For the 1st time in world history, a staggering 99% of countries on Earth joined in unity and signed a legally binding treaty; The Paris Agreement.
This unprecedented agreement sets out to reduce ~50% greenhouse gas emissions by 2030 and become net-zero by 2050, in hopes of saving humanity.

Heading In The Wrong Direction
Current solutions are not working!
Not only are we not on target to reach our greenhouse gas reduction goals but carbon emissions have RISEN since the signing of the Paris Agreement from 49B tons to 54B tons. Furthermore, current solutions do not address atmospheric CO2 which has risen 30% in 40 years to a record 422 parts per million.

Not Low Carbon; A Carbon Negative Solution
Our mission is to develop carbon negative concrete products that turn one of the largest polluting products (concrete) into the leading carbon sequestering & solid waste removal product SIMULTANEOUSLY.
