One of the main advantages of using geoplymer concrete is its significantly lower Co2 footprint compared to conventional concrete. In Tubobel's Geoprime® pipe, the binder is an activated polymer. These geopolymers are by-products from steel production. By using an existing by-product, instead of cement as a raw material, the CO2 emissions of Geoprime® in terms of raw material use are as much as 78% lower than for conventional concrete. Geoprime® pipes are intended for buffering and transporting rainwater and, like other concrete pipes, can be completely recycled into new raw materials at the end of their service life.
