How Green is Cement?

Being about to pour several tonnes of concrete into the floor of our barn I was interested to read about the environmental impact of cement usage. Apparently, world-wide cement production creates twice as many carbon emissions as the world’s airline industry does. For each tonne of cement that is produced 900kg of CO2 is released into the atmosphere ~ heavy stuff!

Moves are afoot from major producers to green the production process. Geocycle in Belgium provides technology that allows waste products to be used to power the kilns in which the ingredients of cement (limestone, calcium, silicon, aluminium and iron oxides) are cooked into a clinker before being crushed to a powder and mixed with further additives such as gypsum.

However, with no obvious substitutes and a voracious world-wide appetite for concrete the opportunities and needs for technology to address the issue of C02 in cement production is paramount.

  1. Hello there,
    Thank you for creating this great site.It’s very useful with lots of advice.Just like you,I try to be as “green” as possible but with costs still being too high for environmental friendly products, we have to compromise.
    I’ve just layed a vast concrete floor(post and beam)and the result is great.I also created a blog of my Barn conversion in France(in french and english) and I’ll put your site on my blogroll to get you some french(anglofiles)visitors.Keep the good work,
    Gustavo
