In terms of costs, savings of 10-28% - compared to costs of conventional plants - can be assumed in most cases. The construction time reduces up to 53%.
CO2 emissions
Although the CO2 emission of 1.35 t from the production of GRP pipes is higher than that of concrete (0.26 t), the emission is put into perspective in a direct comparison of buildings, as GRP storage basins require considerably lower wall thicknesses for the same static loads. If a concrete basin requires a wall thickness of 40 cm for the side walls or 50 cm for the base plate, the same storage chamber can be used with a GRP pipe with a maximum wall thickness of 5.6 cm. If, for example, 2 tanks with a volume of 400 m3 capacity are compared, where one was built from GRP and one from concrete, the result for the concrete basin is a CO2 emission of 72.95 t, and for the GRP tank a CO2 emission of 49.01 t. GRP is therefore not only an excellent structural alternative, the high-tech building material also makes an outstanding contribution to environmental protection.
