CO₂ to cement –
the world’s first economical carbon utilization technology

Solving for sustainability

by partnering with nature.

Fortera’s Nature Inspired Technology

reduces Cement Industry CO₂ Emissions by 60%.

Fortera mimics the same natural processes that turn CO₂ into limestone, utilizing exhaust from cement manufacturing as its feedstock.

Its resulting product converts one ton of limestone into one ton of cement, doubling quarry life.

By feeding emissions back into its manufacturing process, Fortera is able to avoid 60% of the CO₂ generated in traditional cement production. Powered by renewables, Fortera opens a pathway to truly net zero cement.

Unlike Portland cement, which is a calcined blend of limestone, silica, iron oxide, gypsum and alumina, Fortera cement is completely made from limestone. With a wide range of limestone materials available as inputs, Fortera is easily able to expand production capabilities. By reducing the inputs to just limestone, kilns can also operate at lower temperatures and handle higher throughputs at the same scale.

Fortera’s technology is easily embedded into existing cement manufacturing systems

and utilizes existing infrastructure from quarry to kiln.


Reactive Calcium Carbonate(CaCO₃) is naturally formed when Calcium and CO₂ come into contact. In nature, this combination results in a cementitious reaction forming hard materials and robust structures such as shells, rocks, and reefs.

Fortera has developed a process for recreating this natural cement with the ability to stabilize it in a dry powder form only activating its cementitious properties the next time it is wetted.

Our reactive calcium carbonate reacts with water, transforming it from spherical particles to a complex structural network of rods. This transformation is where Fortera cement gets its hardening and binding ability.

Fortera technology has been time tested and proven with 100k hours of R&D and 10 years in application.
