Eco-Cement is a product developed by Australian company, TecEco, that can bring about dramatic reduction in the release of CO₂ into our atmosphere. Portland cement was developed around 200 years ago and is now commonplace all around the globe. It is a mixture of chalk, clay, and calcium that must be cooked in a furnace at around 1450^o. This means that for every tonne of Portland cement produced, a tonne of CO₂ is also released into the atmosphere.

By replacing the calcium with magnesite, much lower furnace temperatures can be used, saving energy, plus Eco-Cement absorbs CO₂ while setting, and for years after. Compared with Portland Cement It is more resistant to salt, acid and chlorine corrosion and at the end of its lifespan it is easier to recycle into new cement products.

Eco-cements can also include up to 95% recycled industrial materials such as fly ash and blast furnace slag in their formulation.
