A new recycling system for expanded polystyrene using a natural solvent. Part 2. Development of a prototype production system

Abstract

A prototype production system for recycling expanded polystyrene (EPS), which uses an orange oil, d-limonene, as the EPS shrinking agent, has been developed. This system consists of an apparatus to dissolve EPS and a recycling plant to separate the limonene solution. The recycling plant can mass reproduce polystyrene with the same mechanical properties as new polystyrene. The recycled polystyrene can be used for packaging a 28 inch TV set. © 1998 John Wiley & Sons, Ltd.
