From builder’s rubble to concrete

Every year about 12 million tons of building rubble is generated in Switzerland, and because of the increasing trend towards demolishing older buildings, this figure is expected to rise over the next few years. This situation is causing two problems – on the one hand, there is not enough room available in landfills to dispose of this quantity of waste, and on the other hand, the building boom is depleting the country’s gravel reserves. There is therefore intense pressure to reuse building rubble.
