Ferrock

Ferrock is a new material being researched that uses recycled materials including steel dust from the steel industry to create a concrete-like building material that is even stronger than concrete. What’s more, this unique material actually absorbs and traps carbon dioxide as part of its drying and hardening process – making it not only less CO2 intensive than traditional concrete, but actually carbon neutral.

AshCrete

AshCrete is a concrete alternative that uses fly ash instead of traditional cement.  By using fly ash, a by-product of burning coal, 97 percent of traditional components in concrete can be replaced with recycled material.
