  • Publication number: 20050274035
    Abstract: A waste conditioning or processing arrangement is provided which can effectively handle waste at its point of generation. In a preferred arrangement, the waste is conditioned by drying the waste and forming the waste into pellets or granules, with the waste also preferably sterilized during the conditioning. The resulting pelletized or granularized waste is remarkably smaller than the input waste, and can conveniently be stored for subsequent disposal or use. The arrangement can be used in a variety of contexts, and is particularly advantageous for food or organic wastes. The system can be used in restaurants or marine vessels for handling kitchen or galley waste. The system can also be advantageously used for certain agricultural waste.

  • Patent number: 6517711
    Abstract: An improved waste treatment system and improved waste treatment system components are provided. In a preferred form, a waste stream is initially separated into primarily solid and primarily liquid components, and the liquids are then fed to a filter assembly. The filter assembly includes a pair of filter elements, and the flow is introduced into the filter assembly at a location between the filter elements. During a filtering operation, the liquid is pumped so that it is drawn through one of the filter elements. Periodically, the flow can be reversed, so that it is directed through the other filter element, at which time the first filter element can also be purged or back flushed. Advantageous waste treatment system arrangements are also provided for household, commercial, or transportation/marine use.

  • Patent number: 6156192
    Abstract: A materials treatment system which initially separates liquid and solid components with a separator. The system can be advantageously utilized for household sewage handling, however various components have other applications. Once the separator separates the solids and liquids, a fire tube combusts the solids with microwaves. The liquids exiting the separator are treated in a liquid treatment system which includes additional particle filtration/separation, treatment of the liquids with an oxidant liquid, and an ultraviolet treatment. An advantageous microwave cavity assembly is also provided for dehydration/combustion of solids exiting the separator and/or for solids filtered from liquids in the liquid treatment system.

  • Patent number: 6044596
    Abstract: A building complex for disposing of toxic or otherwise hazardous waste materials. The complex comprises heptagonal shaped center core structure and five rhomboid shaped wing structures dedicated to waste disposal. The walls, floors and ceilings of the wings include a layer or layers of a composite material comprising a thermosetting or thermoplastic resin, high modulus carbon fibers or the like and borosilicate glass particulate.

  • Patent number: 5905039
    Abstract: A logistic method for transporting and handling materials in a tunnel composting plant, as well as the plant itself includes bringing materials for tunnel composting to the plant. The materials are unloaded into intermediate collection points and compostable material is treated from the materials brought also according to the current recipe. The composting materials are transferred to a composting tunnel that is free at the time, and after composting the composted material is transferred from the composting tunnel to a heap of finished material at its own collection point. Composted material is transported from the heap of finished material to the desired point of use. According to the method, essentially all of the handling of all the materials at the plant is carried out using a wheeled loader, equipped with a mixing and crushing bucket.

  • Patent number: 5853579
    Abstract: A treatment system is provided which can treat solid materials and/or liquid materials. Preferably, a separator initially separates liquid and solid materials, and the solid materials are deposited upon a substrate within a microwave cavity. Liquids remaining with the solid materials drain through the substrate, and the solid materials are subjected to microwaves. The liquids exiting the separator are preferably also passed through a filter assembly which retains any suspended particles remaining in the liquid, and subjects the particles to microwaves. Exhaust filters can also be provided for the microwave cavities, and the exhaust filters can also be subject to microwaves to incinerate any particles remaining in the exhaust gas. Fire tube arrangements for incinerating solid materials retained or extracted by substrates or filters are also provided.

  • Patent number: 5843304
    Abstract: A materials treatment system which includes filtration and treatment of solid and liquid components of a material, such as a waste material. A filter or substrate assembly is provided which allows liquids to pass therethrough, while retaining solids. The solids are then incinerated utilizing microwave energy, and the liquids can be treated after passing through the filter element, for example, utilizing a treatment liquid such as an oxidant liquid. The filter assembly can also include an exhaust filter assembly which removes solids or particulate matter from exhaust gasses, with the retained solids/particulates incinerated utilizing microwave energy.
