Abstract

The invention relates to a device that reduces the volume of polystyrene. The apparatus described comprises a heating means to heat a sample of oil to a temperature below the boiling point of the oil and a means to direct the heated oil on a sample of waste polystyrene. The oil acts on the polystyrene to reduce the aerated form of the polystyrene to a more non aerated form which is smaller in volume and which is acceptable for dumping at a landfill site. The apparatus may be attached to a moveable vehicle for ease of transportation. The invention also relates to a method of reducing the volume of a sample of polystyrene to a more manageable form.
