Start-up hopes to eliminate carbon emissions from global cement market 04:24. Cement is the most widely-used substance on Earth after water. When mixed with water, it forms concrete that becomes ...

When combined with concrete production, this figure is even higher. Rotta Loria foresees putting some of that CO 2 back into concrete and cement to make more sustainable materials for construction and ...

Concrete is Earth’s second-most-used material behind water, creating about four times more CO2 emissions than planes. Some companies are trying to revolutionize the industry.
