We’re constantly looking at how to better our environmental footprint. Whether that’s expanding our low-emission/electric offering or making delivery routes shorter and more efficient. Our dedicated sustainable offering gives customers peace of mind that they’re working with an environmentally conscious supplier.
To celebrate World Environment Day, we have highlighted an exciting development in the cement making process. This innovation will help tackle the rising emissions of the construction industry in Europe.
Cement production is a polluting industry, representing 6% of greenhouse gas emissions in the world, 3% of which are in France.
During the production process of cement, clay, limestone, and sand are used to make a base known as clinker. These materials are extracted from quarries, transported to the production site, and mixed. The mixture is then placed in a furnace for 18 hours at 1450 degrees Celsius.
A tonne of this cement produces between 600 and 800kg of CO2.
With the increasing demand for sustainable housing in Europe, the need for low-carbon materials has never been higher.
French construction start-up Hoffmann Green has developed a cement production process that does not use clinker. The innovative process combines industry bi-products and patented chemical compounds. The reaction caused removes the need for heat and water, lowering CO2 emissions.
This clinker free cement produces around 200kg of CO2 per tonne. This is a significant decrease from the industry average.
Hoffman Green has opened their new manufacturing site and is hoping to produce 250 000 tonnes of low carbon cement.
This is a positive first step in tackling the carbon footprint of the construction industry in Europe. We’re hoping this innovation helps drive the reduction of carbon emissions in the construction industry.
