Kiln

Problem

Cement makes 8% of the world's carbon emissions, and producers have no drop-in alternative that meets building standards.

Çözüm

Kiln replaces 60% of the clinker in cement with treated steel slag, cutting emissions in half with the strength that standards require.

Kimin için

Cement producers and large construction firms with carbon targets.

Pazar

Bottom-up: about 45,000 customers like this in Denmark and nearby, worth roughly $280 million a year at our prices.
