Minus Materials Regenerative Limestone Quarry
Boulder, CO, USAUsing algae to generate carbon negative limestone for cement!
With this breakthrough demonstration project Minus Materials will install and operate a first-of-its-kind “regenerative quarry” pilot project in Boulder County that will support the production of carbon-negative biorenewable limestone using microalgae. Limestone produced can be used as a substitute for conventional emissions intensive ‘clinker’, the base component of Portland cement.
