THE PROBLEM
The production of Portland cement is responsible for 8% of global greenhouse gas emissions annually, each year emitting 2.2 billion tons of CO2.
That means if it were a country, it would be the 4th largest emitter in the world. For every 1 kg of cement made, 1 kg of CO2 is emitted.

THE CAUSE
Conventional cement production is a 200-year-old process that burns fossil fuels to drive a chemical reaction at 2600 °F (1450 °C).
The production of such high temperatures is responsible for half of the emissions.
However—cement has another major problem.
The chemical reaction itself emits CO2, which is responsible for the other half of emissions.

REACTION
Chement is reimagining the way cement is made.
OUR TECH
Our technology gets rid of the highly-polluting coal-fired kilns, using renewable electricity and the same raw materials to perform the chemical reaction with less energy and less CO2 emitted. Chement technology also enables carbon capture that is cheaper and easier than carbon capture in conventional cement production.
The result:
More efficient production
No energy emissions
Easier carbon capture
