Europe Tries New Way To Recycle PVC.The first plant to use the Vinyloop selective dissolving process to recycle PVC PVC: see polyvinyl chloride. PVC in full polyvinyl chloride Synthetic resin, an organic polymer made by treating vinyl chloride monomers with a peroxide. is being built in Ferrara, Italy, and is due to start up by mid-2001. Developed by Solvay S.A. in Belgium, the process uses biodegradable biodegradable /bio·de·grad·a·ble/ (-de-grad´ah-b'l) susceptible of degradation by biological processes, as by bacterial or other enzymatic action. bi·o·de·grad·a·ble adj. solvents to separate vinyl from other waste materials. After the PVC-containing solution is drawn off from the other waste, chemicals are added to precipitate precipitate /pre·cip·i·tate/ (-sip´i-tat) 1. to cause settling in solid particles of substance in solution. 2. a deposit of solid particles settled out of a solution. 3. occurring with undue rapidity. out the PVC. The solvent is reused in a closed circuit. The reclaimed PVC is reportedly of near-virgin quality. This method will be used to recycle post-consumer electrical cables and flexible packaging in a facility sized to handle 19 million lb/yr. The plant will cost $7.7 million and is being built by a joint venture of Solvin Italia (a Solvay/BASF joint venture that makes PVC), Adriaplast (a Solvay Group subsidiary that makes packaging), Fitt S.p.A. (an Italian PVC pipe producer), Tecnometal s.r.l. (a cable recycler), and Vulcaflex S.p.A., a vinyl calendering calendering, a finishing process by which paper, plastics, rubber, or textiles are pressed into sheets and smoothed, glazed, polished, or given a moiré or embossed surface. firm. |
