CO2 emission reductions by using geosynthetics

The amount of traditional poured concrete needed to cover the same area as a single pallet of 8mm thick GCCMs would require two 17-ton mixing trucks. Material savings on a typical construction project can be up to 95% when using GCCMs compared to traditional methods. For decades we have seen cement mixers stationed at construction sites around the world. The process of mixing the powder to create concrete has been crucial in engineering projects of all shapes and sizes. While many may simply accept this as the standard way to produce concrete, there is an alternative which has some significant environmental benefits compared to the traditional method. The harmful environmental nature of cement may not be known to all but the figures in a 2018 Chatham House report detail just that. As the world most widely used construction material, it is a major source of carbon dioxide. Cement contributes around 8 per cent of the world’s CO2 emissions. GCCMs arrive on-site on a roll ready to install. Poured or sprayed concrete needs to be mixed on-site, which means running a mixing machine for prolonged periods of time. Not only is this damaging for the environment because of the cement needed, but the mixing machine is also contributing harmful emissions such while running.
