Polystyrene is not easily recycled because of its light weight especially if foamed and its low scrap value. It is generally not accepted in kerbside (curbside) collection recycling programs. In Germany, however, polystyrene is collected, as a consequence of the packaging law (Verpackungsverordnung) that requires manufacturers to take responsibility for recycling or disposing of any packaging material they sell. On the other hand, great advances have been made in recycling expanded polystyrene at an industrial level. Many different methods of densification have been developed. This increase in density, usually greater than 15#/cubic foot makes clean polystyrene a good profit center in recycling operations. Some industrial polystyrene manufacturers accept post consumer EPS for recycling. As an example Dart Container Corporation in Mason, Michigan has an ongoing post consumer recycling operation as well as an industrial EPS scrap recycling operation.
