At the September meeting the Irish Wildlife Trust Dublin Branch and Dublin Green Drinks heard Susan McGarry, Environmental Manager with the innovative Ecocem Ireland talk about the importance of embodied carbon in the built environment; how we need to shift our focus on to the embodied carbon of construction materials rather than the operational energy of buildings, and how low carbon, long-lasting, recycled materials like Ecocem's cement replacements can make a huge difference. Embodied carbon means the amount of carbon that is used making the material, as opposed to operational carbon that is emitted to produce energy.
Susan talked about Ecocem's low carbon cement which is based upon iron slag and as such is based on a 100% recyclable material. It therefore creates far fewer carbon emissions in its production than ordinary cement. This base also makes their ecocem GGBS cement very long lasting and durable, generally doubling the life of structures made from it, in comparison to similar structures made from ordinary cement. This of course reduces the amount of carbon emissions overall. Most of the carbon footprint of any structure is made during its construction, so if this is reduced there is a significant saving.
Climate change concerns us all. Despite repeated warnings, and its effects being felt around the world, we have yet not managed to do very much about it. Ecocem products at least offer one way we can help to reduce carbon emissions.
