A process of treating sewage sludge and the formation of a granular product thereof, wherein said process comprises utilizing a urea-formaldehyde resin to treat a sludge product from thermal hydrolysis processes (THPs) to create an end product for agricultural and other uses. The process utilizes a high intensity mixing and chopping reactor, which combines the sludge with a resin and utilizes sulfuric or other mineral acid to polymerize the resin. The resultant product is subsequently dried and sized through a screening process. The process results in an end product that is a granular fertilizer that is substantially dehydrated and a substantial portion of the nutrients having low solubility and slow release rates. This reduces or eliminates the loss of plant nutrients to water runoff effects. The novel process results in a product that is a low-odor, enhanced fertilizer useful for the processing and utilization of sewage sludge for agricultural and other purposes.

Disclosed are methods of dewatering solid byproduct. In some embodiments, the solid byproduct contains particles and is produced from a fermentation process for making an oxygenated compound such as ethanol. The method comprises a chemical sequence for conditioning (pre-treating) the solid byproduct to be dewatered. The solid byproduct (in water) is treated with alkaline material to increase its pH to about 7-8.5. Coagulant is added to the alkaline-treated solid byproduct to reduce charge on the solid byproduct. An agglomerating polymer is then added to increase the average size of the solid byproduct particles to a desired size (e.g., at least about 1 mm). Dewatering can further use known technologies such as screw press, belt press, filter press, centrifuge, and/or a dryer to separate the conditioned or pre-treated byproduct from water. Also disclosed are methods of producing oxygenated product, as well as methods of producing animal feed and/or fertilizer, respectively.

A brine waste management method comprising the utilization of brine waste as a growth medium for cultures of genetically modified halophiles acting as bio-refineries creating chemicals of value. Brine waste enters the method (101) to undergo compositional analysis (102), Pretreatment (104), and Inoculation (106). The compositional analysis (102) and the selection (103) of the chemicals of value influences the selection (103) of the halophile species to undergo modification (105), as well as the pretreatment (104) needed to encourage growth-production (107). Growth-production (107) is monitored and assisted until the extraction (108) of the chemicals of value and additional post-extraction (109) handling of excess brine waste exiting the method.

The present invention relates to a method of treating sludge containing phosphorus, ammonia and magnesium and enhancing the dewaterability of the sludge. The sludge is directed into a biological fermenter operated under anaerobic conditions. By controlling the temperature of the sludge in the fermenter or the hydraulic retention time of the sludge in the fermenter, phosphorus, ammonia and magnesium is released from the solids in the sludge into a liquid forming a part of the sludge. Sludge from the fermenter is subjected to a solids-liquid separation process that produces a concentrated sludge and a liquid. The concentrated sludge or separated solids is directed to a thermal hydrolysis reactor that thermally hydrolyzes the concentrated sludge. After thermally hydrolyzing the concentrated sludge, the concentrated sludge is directed to an anaerobic digester that anaerobically digests the concentrated sludge.

A system of waste management and compost generation comprising: a waste collection system wherein waste is collected in separated compostable and non compostable waste streams from at least one source in trackable bins; and wherein the trackable bins contain separated compostable and non compostable waste streams from at least one source; a processing facility which receives and processes the compostable and non compostable waste in the trackable bins; a sorting system for further processing the waste from the trackable bins into a compostable stream and a non compostable stream; a communication and data entry system for collecting the data from the sorting system and reporting the data to at least one source; a composting system which processes the compostable stream into compost material; and a processing system that processes or bundles a high percentage of the non compostable stream into useful products.
