Natural stone is ecological

October 26 - 2016

Natural stone as a building material is found naturally in virtually finished form. No energy is needed for its actual manufacture. Energy is only consumed for quarrying and processing, but the share is small compared with other building materials. The stone is extracted mostly from relatively small quarries with major blasting operations. The unused stone waste can be used directly for filling in the parts of the quarry where stone has been extracted or for other practical uses. Nothing is lost in the complete cycle of natural stone quarrying, processing and the return to nature.
