A3782 Using recycled wallboard
نویسنده
چکیده
Much of this material is not reusable and is usually deposited in a landfill. A study conducted in Wisconsin estimated that construction of a typical single family home in 1992 encumbered waste disposal expenses of over $700.2 The study estimated that between 77,000 and 102,000 cubic yards of construction waste was generated in Dane County alone, at a disposal cost of between $1,000,000 and $1,450,000. Wallboard was estimated to make up 15% of the waste by volume.
