Very little material is wasted after the demolition projects. Materials from demolished buildings can easily be salvaged, recycled, or reused. Removal and transportation of these materials from the site will be taken care of by the demolition company. Common materials that are useable from demolition sites include aggregates like bricks and concrete, scrap metal containing iron and steel, wiring materials, flooring, tiles, and wood. A properly done demolition project will have up to 90% of scrap materials put up for salvage and recycling.
