Abstract

It was shown in previous papers that the plastics which are presently considered to be a waste stream from a materials recovery facility (MRF) can be made into products which possess consistent properties. It has now been demonstrated that the addition of another waste plastic, polystyrene, to the commingled plastic waste dramatically increases the mechanical properties of these materials. In fact, the increase in modulus is even greater than that predicted by simple composite materials calculations for some compositions. Although polystyrene is not presently collected by most recycling systems, even most of those which collect plastic containers, it should be readily available to recyclers in fairly steady quanties from such sources as fast food restaurants which should be happy to comply with recycling rather than having one of their main packaging materials banned. From the information presented in this paper it is recommended that recycling systems begin to collect polystyrene so that it may be incorporated into products such as those produced by the ET/1 extrusion molding machine in order that 'value added' materials may be produced for some applications.
