H-Zero is the first plant in the country dedicated to the recovery and washing of waste from construction, excavation and demolition to obtain an excellent quality recycled aggregate . Demolition is not the end, but the beginning of a new life cycle of materials. Beyond managing waste, we turn each demolition into a resource bank reusing waste to make sustainable concrete . With this we manage to minimize the environmental impact, reduce the exploitation of natural resources and demonstrate that the circular economy and real sustainability are two essential advances in the construction sector.
