The treatment process is conducted in a single vessel, wherein air and water are evenly distributed to the contents of the vessel. A plurality of vessels may be interconnected, such that water may be extracted from one vessel, whose contents have undergone anaerobic digestion, then recirculated to an interconnected vessel to facilitate conditions for anaerobic digestion of the contents of the interconnected vessel.Type: GrantFiled: July 20, 2000Date of Patent: May 1, 2007Assignee: Organic Resource Technologies LimitedInventor: Tomasz Rudas

Patent number: 7135332Abstract: Improved systems, methods, apparatus and compositions for generating, extracting and distributing the renewable heat energy produced by microbial decomposition of organic biomass within a contained and controlled environment. This heat energy is preferably transferred and distributed, preferably by the use of heat pipes, to the interior of a greenhouse or other structure to be heated, either directly or via heat exchange apparatus such as hot water heating systems. In one embodiment heat transfer and distribution mechanism customized to the application requirements of a greenhouse heating batch-type process is disclosed, along with a recipe for a readily available biomass material composition that will slowly decompose while it generates a substantial quantity of usable heat energy to be consumed in the elevation of temperature in a separated greenhouse basement confinement area.Type: GrantFiled: July 8, 2002Date of Patent: November 14, 2006Inventor: Joseph P.

Patent number: 6946288Abstract: A ventilation system is disclosed for an enclosure in which people live. The ventilation system comprises a first ducting means for ducting fresh air from outside to inside the enclosure and a second ducting means for ducting stale air. The second ducting means comprises a stale air inlet for receiving stale air containing carbon dioxide from inside the enclosure and an exhaust manifold having a first vent to exhaust air outside the enclosure and a second vent in fluid communication with the first ducting means to return clean air into the first ducting means. The ventilation system is further characterised in that it comprises catalysing means for catalysing hydration of carbon dioxide contained in at least a portion of the stale air into a solution of carbonate ions and hydrogen ions, and thereby removing carbon dioxide from said portion of the stale air and obtaining clean air. Evacuating means are also provided for evacuating the solution out of the ventilation system.Type: GrantFiled: May 31, 2002Date of Patent: September 20, 2005Assignee: CO2 Solution, Inc.Inventors: Jean-Sébastien Blais, Jean Ruel, Frédéric Dutil

Patent number: 6924140Abstract: A system for capturing and neutralizing HAP's (hazardous air pollutants) and VOC's (volatile organic compounds) at the source point by providing a closed loop remediation system which utilizes an air collection, treatment and control module containing a predetermined size bay of multiple interchangeable mini-biofilter cartridges that function to consume the pollutant and recirculate remediated air back to the source point of the pollutant. The system includes establishing a closed loop air system at a work station which generates and emits VOC's, capturing the VOC's in the air stream flow and transporting them directly into an adjacent biofilter module which contains selected microorganisms in mini-cartridges which biodegrade said VOC's and recirculates remediated air back to the source point of the pollutant.Type: GrantFiled: June 14, 2002Date of Patent: August 2, 2005Inventor: Lewis J. Daly

Publication number: 20040259231Abstract: This invention pertains to a novel biotechnological process of solubilization and concentration of CO2 from emission exhausts or streams that could be coupled for further biochemical/chemical conversion. The biotechnological process occurs in novel reactors/devices employing immobilized biocatalysts enabling concentration and solubilization of emitted CO2 by allowing catalytic contacting with water spray. These novel reactors or devices could be coupled to other reactors/devices resulting in further biochemical/chemical conversion of the concentrated carbon dioxide.Type: ApplicationFiled: June 18, 2003Publication date: December 23, 2004Inventor: Sanjoy K.

Publication number: 20040203139Abstract: This invention falls into the category of micro biotechnology. The claim is creation of the bioreactor populated with community of microorganisms, which participate in the process of oxygenation of carbohydrates of the natural origin and, as a final result, production of methane gas-CH4. The new bioreactor makes possible the use of methane in automobile and energy production. At the same time it does not create harmful discharge into the atmosphere and keeps the environment 100% free of contamination. This invention applies a unique makeup of microorganisms: producers of methane. Produced methane is pumped through a system of pressure regulators into internal combustion engines, which are used in the energy production and other areas of industry. The bioreactor doesn't have any analogies in the world practice. Its application allows to discontinue the use of oil as the basis for production of gasoline and to replace other energy producing media.Type: ApplicationFiled: May 26, 2004Publication date: October 14, 2004Inventor: David Shtok

Publication number: 20040172878Abstract: The method according to the invention concerns an anaerobic conversion of biomass into biogas in separated processes of hydrolysis and methane fermentation of biomass by means of methane mesophile, thermophile and psychrophile bacteria, contained in returned reflux. Cleaned biogas undergoes decomposition into methane and carbon dioxide. From part of methane and biogas standard gas fuel is produced, used for the engine of a current generating unit and a thermoregenerative cell generating electrical energy and heat. The system according to the invention consists of a system of preparation of biomass (1) connected to a hydrolyser (2) and then to a series system of fermentation tanks and a composter (1), which co-operates with a system of returning and enriching reflux (4).
