Abstract: The invention describes a new method for treating sludge, which can result in the production of high nitrogen organically-augmented inorganic fertilizer that incorporates municipal sludges or biosolids or organic sludges that can compete with traditional fertilizers such as ammonium phosphate, ammonium sulfate and urea on the commodity fertilizer marketplace. The method takes advantage of the thixotropic property of dewatered biosolids or organic sludge to create a pumpable paste-like material from the biosolids or organic sludge that is then treated with an oxidizer to reduce odorant effects and an acid. This mix is then interacted with concentrated sulfuric and or phosphoric acids and an ammonia source or alternatively a hot or molten melt or salt of ammonium sulfate/phosphate to form a fertilizer mix. The present invention controls the heat, atmospheric pressure and retention time of the fertilizer mix in the reaction vessel.

Abstract: Liquid compost is made automatically and continuously. A rotating carousel, mounted above a tank, receives organic material, and a plurality of nozzles spray fluid onto the carousel, so as to entrain particles of organic material. The fluid and the particles pass through a screen in the carousel, and into the tank. Residual organic material which has not passed through the screen is removed from the carousel by a nozzle oriented to push such material off the carousel. A system of conveyors automatically delivers fresh organic material to the carousel, and removes spent organic material from the carousel. The entire system operates continuously, so that liquid compost, or compost tea, can be made efficiently.

Abstract: The present invention relates to methods and apparatuses for the production of organic liquid fertilizer from waste using a two-phase process. The first phase comprises a successive extraction process whereby liquid leachate is drained from one plant or storage container and the process subsequently re-started with new fresh water.
