Patent number: 4311510Abstract: A method for producing a fertilizer and decay promoting substance by subjecting grape marc to aerobic decay so that in a first phase, the sugar content is converted to alcohol and microbial fermentation produces organic acids. During the first phase, the alcohol and acids react to produce aromatic esters and a decay stabilized mass. In a second phase, the mass is rearranged to facilitate access of air and promote penetration of the mycelia of Humicola lanuginusa and thermophilic actinomycetes into the mass. In a third step, the mass is rearranged to effect microbial degradation of the mycelia and the mass is dried and the pip-containing fraction is separated. The thus obtained pips or seeds are infested with spores of the above-mentioned microorganisms and still contain their natural oil content and constitute an excellent high-grade fertilizer and aerobic decay promoting agent for the decay of vegetable and animal waste materials.Type: GrantFiled: October 28, 1980Date of Patent: January 19, 1982Inventor: Gernot Graefe

Patent number: 4302236Abstract: Disclosed is a method for removing inorganic acid-forming constituents from a gas stream contaminated therewith (e.g. high sulfur coal effluent). Such removal is accomplished by passing the gas stream through an active composting biodegradable organic waste held under thermophilic bacteria-phase digestion conditions. Also disclosed is a comprehensive composting treatment site which desirably employs a windrowing composting technique and is suitably adapted to be operated with the gas stream scrubbing process disclosed herein.Type: GrantFiled: February 20, 1980Date of Patent: November 24, 1981Assignee: Ultimate Resources, Inc.Inventor: Walter C.

Patent number: 4302546Abstract: An airtight chamber insulated with an anti-corrosive coating allows the control of the heat and moisture content of organic wastes for rapid aerobic decomposition by naturally occurring thermal bacteria. Air is drawn into the chamber, over and through the organic waste and carbonaceous filler materials and is exhausted through an air scrubber. Agitation of the waste mixture is by means of two or more anti-corrosive coated stirrers on a rotating shaft; the rotation rate being two revolutions or less per minute to accelerate the biological decomposition process and 35 or more revolutions per minute to fluff and dry the material after the completion of the biological process. During the drying process the air direction is reversed by means of a blower and a controlled heating element to speed drying. Utilization of the blower and heating element also helps to initiate the biological decomposition activity in cold temperatures.Type: GrantFiled: May 19, 1978Date of Patent: November 24, 1981Inventor: Harold E. Schlichting, Jr.

Patent number: 4288241Abstract: Sludge is composted by arranging the sludge in a pile over a conduit and air is forced into the pile in spaced time intervals and air is drawn from the pile into the conduit in alternate time intervals.The perforated conduits are adapted to be placed under and extend the length of two windrow compost piles. A reversible blower is connected to blow air to and withdraw air from each of the conduits. The blower is timed and controlled to blow air from a first pile through the conduits and into a second pile in spaced time intervals and in alternate time intervals to withdraw air from the second pile through the conduits and into the first pile.Type: GrantFiled: July 26, 1979Date of Patent: September 8, 1981Inventor: Gedaliahu Shelef

Patent number: 4272489Abstract: A device for composting refuse and sewage slurry, consisting of a rotating drum supporting substantially horizontally with a fixed front wall through which refuse and sewage slurry are fed to the drum, and a fixed rear wall through which the mixture in the drum may be extracted. Means are provided enabling air or another gas containing oxygen, to be passed through the drum either from the front to rear or vice versa. The gas flow is adjustable by regulators in the pipelines taking air to and from the drum. The pipeline supplying air to the drum may be connected to a blower, and means may be provided for regulating the temperature in the drum, and for the complete or partial return of air sucked out of the drum to the drum.Type: GrantFiled: November 21, 1978Date of Patent: June 9, 1981Assignee: Ruthner Industrieanlagen-AktiengesellschaftInventors: Willibald Lutz, Heinz Mooss

Patent number: 4264352Abstract: A method for composting solid waste material wherein, in initial treatment stages an optimum particle size is developed at a comminution station. Following an initial air classification arrangement, heavy inorganic materials are segregated to the extent that aluminum, glass and paper characterized products are removed for recycling purposes. A characterizing feature of the invention resides in the development of an optimized moisture content or digestible classified size optimized material at a relatively early stage prior to maceration developing a pulpous substance for digestion. A pug-mill arrangement is utilized for adding optimized moisture prior to digestion and maceration and a cage mill is utilized for the maceration stage of the process.Type: GrantFiled: March 17, 1980Date of Patent: April 28, 1981Assignee: Aerotherm, Inc.Inventor: John E.
