The process, developed by United Resource Recovery Corp. (URRC URRC United Resource Recovery Corporation (recycling company) URRC Ubon Rice Research Center (Thailand) ), Spartanburg, S.C., has been used on a commercial scale only in Europe, where two plants each recover 30 million lb/yr of PET. (URRC also operates a 10-million-lb/yr demonstration plant.) PET flake is cleaned by removing a thin surface layer of resin with embedded Inserted into. See embedded system. contaminants. This is done by spraying the flakes with a caustic soda caustic soda: see sodium hydroxide. caustic soda Sodium hydroxide (NaOH), an inorganic compound. The alkalies called caustic soda and caustic potash (potassium hydroxide) are very important industrial chemicals, with uses in the manufacture of solution, then heating them in a rotary oven to depolymerize the surface layer. These steps are followed by washing and drying. Tel: (864) 574-0904, www.urrc.net |
