Recycled plasterboard may be used in investment casting molds.Two new end markets for recycled plasterboard are being explored in new research and development trials--one of which will feed the metalcasting industry. CERAM Ceram, island, Indonesia: see Seram. Ceram or Seram Island of the central Moluccas, Indonesia. It has an area of 6,621 sq mi (17,148 sq km). The terrain is mountainous and covered with tropical forests; seismic activity is common. Research, Staffordshire, England, and Coventry Univ., Coventry City, England, have received funding to research and develop new potential end markets in the hope of diverting used plasterboard away from landfill sites landfill site n → vertedero landfill site n → centre m d'enfouissement des déchets landfill site land n . In the first project, CERAM will be conducting studies on the potential use of recycled plasterboard in ceramic and metalcasting molds. By adapting an existing patented process, the company is converting relatively low specification waste plasterboard to a higher value, high purity, raw material suitable for making molds for use in the investment casting investment casting Precision casting for forming metal shapes with minutely precise details. Casting bronze or precious metals typically involves several steps, including forming a mold around the sculptured form; detaching the mold (in two or more sections); coating its process, specifically for aluminum components. Following the refinement of the process in the laboratory, CERAM will conduct factory-scale trials of test molds in production environments. Success of the project could lead to significant tonnages of waste plasterboard being diverted from landfills and benefits to the casting industries, which include providing an alternative and sustainable source of mold material at a potentially lower cost. In the second project, Coventry University The expanding main campus is situated on the east side of Coventry city centre, which boasts one of the most innovative (and unusual-looking) university libraries in the UK. The university is particularly noted for its world-renowned automotive design and engineering degree courses as will be developing cost effective, novel cement mixes using recycled gypsum gypsum (jĭp`səm), mineral composed of calcium sulfate (calcium, sulfur, and oxygen) with two molecules of water, CaSO4·2H2O. It is the most common sulfate mineral, occurring in many places in a variety of forms. from waste plasterboard, and a range of mineral wastes. |
