The startup is using waste materials and alternative fuels to make cement, slashing greenhouse gas emissions in a polluting industry.
Cement is one of the most used materials on the planet, and the industry emits billions of tons of greenhouse gasses annually. Cemvision wants to use waste materials and alternative fuels to help reduce climate pollution from cement production.
Today, making cement requires crushing limestone and heating it to super high temperatures, usually by burning fossil fuels. The chemical reactions also release carbon dioxide pollution.
Swedish startup Cemvision made a few key production changes to reduce both emissions and the need to mine new materials. First, the company is moving away from Portland cement, the most common form of the material used currently.
The US Department of Energy cuts could spell trouble for clean cement.
