Patent number: 6368657Abstract: A practical precipitation recovery process for food waste sludge from dissolved air floatation (DAF) units and sugar by products is provided. Typical meat DAF (dissolved air floatation) skimming sludge has about 12% solid with about 40% fat and 42% protein in solid basis.

The process converts the skimming sludge and animal blood into a precipitate, which binds most nutrients. Then the precipitate product can be separated easily by a centrifuge, screen or press process. The dry process cost can be reduced because the extra water is removed and the product surface area is increased. The process can convert the waste skimming sludge into a value added product as a good and safe ingredient for feed and nutritional applications. A typical dry product has about protein 54%, pepsin digestible protein 96%, fat 23%, ash 8.Type: GrantFiled: August 1, 2001Date of Patent: April 9, 2002Assignee: Rigel Technology CorporationInventor: John H.

Other processes for degrading compounds such as chlordane, dieldrin, toxaphene, aldrin, endrin, and heptachlorepoxide as well as polychlorinated benzenes are also disclosed.Type: GrantFiled: May 18, 1998Date of Patent: July 4, 2000Assignee: Zeneca, Inc.Inventors: Guy P. Moser, Neil C. C. Gray, David J. Gannon

Patent number: 6042629Abstract: A process provides for the production of fertilizer solutions from brewery cleaning solutions. The process comprises the steps of combining a brewery caustic potash cleaning solution with a brewery nitrogen- or phosphorus-containing acid cleaning solution in mutually neutralizing amounts. This process results in the production of a fertilizer solution comprising a neutralized potassium salt solution having nitrogen-containing, organic, brewing materials entrained therein. If desired, spent grains and/or spent yeast from the brewing process can be added to provide further nutrients.Type: GrantFiled: December 31, 1997Date of Patent: March 28, 2000Assignee: Labatt Brewing Company LimitedInventor: Michael Jerome McGarrity

Patent number: 6039782Abstract: The present invention relates to a process for producing granulated organic matters wherein a precipitated fraction obtaied in a settling tank from a methane fermentation fluid having been treated aerobically in an aeration tank is added to a fermentation waste fluid. According to the present invention, there is provided a process for producing physically stable granulated organic matters with reduced increase of stickiness occurring at the time of manufacturing granulated organic matters from fermentation waste fluid.Type: GrantFiled: January 16, 1998Date of Patent: March 21, 2000Assignee: Kyowa Hakko Kogyo Co., Ltd.Inventors: Akio Sota, Tomoo Okiura, Masaki Azuma

Patent number: 6033899Abstract: A process of decontaminating soil containing pentachlorophenol (PCP) contaminant comprising admixing an organic nutrient material into soil in an amount of about 10% to 95% by weight of the soil mixture. The soil mixture forms a compost mixture. Composting the compost mixture at a temperature in the range of 20 to 65 degrees celsius. The water content of the compost mixture is maintained in a range of 40% to 100% water holding capacity (WHC). The redox potential level during the composting is below negative 200 mV to achieve partial degradation of the PCP contaminant. After composting, the compost mixture is oxygenated to raise the redox potential to positive 100 mV to further degrade the contaminant; and the steps are repeated until the PCP contaminant is present in an amount less than 140 ppm per ton of soil. The organic nutrient material comprises agricultural waste and municipal waste.Type: GrantFiled: May 18, 1998Date of Patent: March 7, 2000Assignee: Zenca, Inc.Inventors: Guy P. Moser, Neil C. C. Gray

Patent number: 5998199Abstract: The present invention provides a process of decontaminating, by composting under specific conditions, soil and/or sediments containing toxic contaminants of TNT, HMX and RDX. The process is carried out by converting the contaminants into harmless materials. The process includes the step of affecting a solid compost mixture during composting with a redox potential below negative 200 mV (millivolts). Further, the process includes several steps which are repeated until complete degradation is achieved. Other processes for degrading compounds such as chlordane, dieldrin, toxaphene, aldrin, endrin, and heptachlorepoxide as well as polychlorinated benzenes are also disclosed.Type: GrantFiled: May 18, 1998Date of Patent: December 7, 1999Assignee: Zeneca IncInventors: Guy P. Moser, Neil C. C. Gray

Patent number: 5984579Abstract: Synthetic soil is created by blending processed or unprocessed incinerator ash, derived from solid waste or other materials, with either compostable materials or compostable materials derived therefrom. The blending of these materials results in residual biotech soil which can be used as a plant-growth medium; as cover material for such things as landfills, disturbed soil areas or mined-land reclamation; and as a medium to treat contaminated water.Type: GrantFiled: July 2, 1993Date of Patent: November 16, 1999Inventor: Richard J. McClimans

Patent number: 5976211Abstract: A process for producing a fertilizer from an organic waste material is described which comprises treating a waste, having a water content of no more than 90% by weight and which has been alkalinized, with nitrogen dioxide or a precursor thereof in sufficient amount to reduce the pH by at least 2.0 pH units. The process produces an organic fertilizer in which the percentage by weight of nitrogen in the form of oxides of nitrogen is higher than percentage by weight of nitrogen in the form of ammonium ion.Type: GrantFiled: December 31, 1997Date of Patent: November 2, 1999Assignee: Agronova A/SInventors: Erling Fjelldal, .O slashed.yvind Vartdal, Svein Slangsvold, Pal Jacobsen
