  • Patent number: 7498163
    Abstract: The present invention is related to a process for reducing solid waste volume and landfill mass. More particularly, the process of the present invention is directed to reducing organic waste with or without production and collection of a useful product. The process of the present invention involves supplying at least one oxidizing agent in the presence of an aqueous medium into organic materials. The oxidizing agent oxidizes and breaks down a portion of these materials. After addition of the oxidizing agent, at least one species of microorganism may be supplied into the channel and the microorganism consumes the oxidized organic material.

  • Patent number: 6893565
    Abstract: The present invention is generally directed to a process and system for treating animal waste. More particularly, the present invention is directed to a process and system for treating animal waste effluent with ozone to decompose the organic material within and improve the odor of the animal waste. The process of the present invention also reduces biochemical oxygen demand, chemical oxygen demand, total bacterial content and coliform bacterial count of the animal waste. The process of this present invention comprises collecting an animal waste solution, containing a mixture of water and animal fecal material; contacting the waste solution with ozone in an amount sufficient to oxidize at least a portion of the organic material contained within; and feeding the ozone treated waste solution to a solids separating device prior to collecting the waste solution in a biobasin or, alternatively, recycling the ozone treated waste solution for use as a source of irrigation or flushwater.

  • Patent number: 6835560
    Abstract: A process for converting organic waste materials into useable products and products thereof is disclosed. According to the process, organic waste materials are contacted with ozone thereby converting said waste material to a substrate or medium. The substrate is a product of the process and it may be further contacted with organisms for bioconversion to further products. The organisms can include bacteria, yeast, fungi, plant cells, animal cells and genetically engineered organisms which are selected for their ability to bioconvert the substrate and produce a selected product.
