Abstract: A separator for separator a paper ply from a polymer or other ply of heterogeneous, multi-ply packaging materials subjects the packaging materials to high pressure liquid delivered from a plurality of rotating nozzles. The packaging material is delivered into the chamber from a pre-wetting or soaking station. The nozzles in the chamber separate the paper from the polymer and reduces the paper to fibers. The polymer is skimmed off the top of the chamber in which the material is treated. The water and pulp are delivered to a settling tank where the paper fibers settle and water is removed. The remaining liquid and the paper fibers are delivered to a centrifugal screw where the remaining water is removed from the paper.

Abstract: A microwaveable food container is provided with an accessory which contains a heat assist to facilitate heating of the food. The accessory is secured to the container along two opposite edges of the accessory and is provided with perforations which allow the metallized heat assist to be easily removed. The remaining portion of the container may therefore be recycled.

Abstract: A method of treating yard waste includes introducing yard waste into a chamber wherein the yard waste is impinged by high pressure jet of liquid; the liquid from a group of rotating nozzles. The pressurized liquid stream breaks down the yard waste to create a greater surface area for biological microorganisms to attack, thereby speeding up the decomposition of the waste.
