Abstract
A densification apparatus for use in recycling plastic containers utilizes a hopper with a movable lid to feed collected plastic containers to a continuous chain conveyor having a plurality of wedge-shape teeth which perforate the containers and urge them between a set of compression plates and rollers such that the plastics are compressed beyond their ability to resume their original shape. The vertical conveyor and hopper-closing lid prevent ballistic rejection of containers and enable iterative processing of plastic in a movable or stationary curbside apparatus.
