ABSTRACT:
System and method for densifying expanded thermoplastic foam materials such as loose fill packing materials, larger blocks of such materials, and food and beverage service items to reduce the volume of such materials for recycling or disposal. The material is heated to soften the material and expel gas from cells within the material and thereby shrink the material to a reduced volume. In some embodiments, and the material is further densified by compacting the heat softened material to further reduce the volume.
