<p>Disclosed is a process for increasing the density of thermoplastic resin foam waste material having apparent density as low as 5 kg/m3. The waste material in particle form is uniformly dispersed onto at least one vibrating plate of a furnace, and then heated to a temperature ranging between about 120 DEG C. and about 210 DEG C. The waste material is then compacted at the outlet end of the furnace and ground into particles of uniform size to be reused as thermoplastic resin material.</p> |
