  • Patent number: 5871114
    Abstract: The invention provides a new method of recycling recyclable waste products suited for household use wherein the container is a plastic injection-molded container having a monolithic body formed from plastic resin and includes a pair of integral compartments. Fibrous waste is placed in one compartment and nonfibrous waste comprising rigid and semirigid container, e.g., glass jars, metal beverage and food cans, plastic bottles and glass bottles are placed in the other compartment so as to presort the recyclable articles. The container is then taken to a collection point where the presorted products can be picked up by a recycling collection contractor and maintained separate from one another during transport to a recycling center.

  • Patent number: 5558254
    Abstract: A combined waste recycling and disposal method utilizes a first container or bin having at least one supporting wheel for supporting the bin from the ground. Waste of a first category, e.g., garbage, is stored in the bin. A second container is provided for waste of a second category, specifically, recyclable waste. Waste of the second category is placed in and stored in the second container. The second container is supported on the first container and thereafter the first container is transferred to a pickup point while loaded with both recyclable and non-recyclable waste by moving the first container while it is supported by the wheels. The second container is then removed from the first container and the waste from both containers is transferred to separate compartments of a pickup vehicle, e.g., a truck for hauling the waste to a recycling and a disposal location. The second container is a rigid receptacle with two or more side-by-side compartments for recyclable waste.

  • Patent number: 5390813
    Abstract: A recycling container formed from plastic resin includes a pair of side-by-side upwardly opening integral compartments having a hollow partition between them. Each of the compartments has upright side walls and an upwardly opening wide mouth with a peripheral or top edge for forming the rim of the container. The upper edge of two adjacent side walls that make up the sides of the partition are joined together by a horizontally disposed connecting panel located in the plane of the container rim for defining the upper margin of the hollow partition between the compartments. The center portion of this connecting panel is a carrying handle. The invention also provides a new method of recycling recyclable waste products suited for household use wherein the container is a plastic injection-molded container having a monolithic body formed from plastic resin and includes a pair of integral compartments.
