HR Cement, based in Tauranga, has developed a new cement named ‘Eco-cem’. This pozzalan based cement has a much lower carbon footprint than normal cement.
Globally cement production accounts for around 5% of carbon dioxide production. Roughly one tonne of cement produces one tonne of carbon dioxide. Eco-cem cement has significantly reduced embodied carbon dioxide. Yet it has the same strength gain as normal cement and costs the same.
HR Cement currently produces 100,000 tonnes of ‘normal’ cement. If it converted all production to the Eco-cem cement, the saving would be 25,000 tonnes of carbon dioxide.
Eco-cem was first produced in early 2017 after extensive testing and development. Around 500 tonnes has been produced so far for trials. Production will be ramping up over the next few months as HR Cement establishes markets and customers.
HR Cement is a finalist in the Revolutionising Energy category of the 2017 NZI Sustainable Business Network Awards
