Methods and systems for manipulating varied biological recyclable streams to produce agricultural admixtures are herein described. The resulting agricultural admixtures can be used to enhance crop yield, or as an animal provender. Managing the sources of varied biological recyclable streams can afford agricultural admixtures with controlled properties.

Methods and systems for pre-treatment of sludge and biosolids in preparation for electrochemical valorization is disclosed herein. Such methods can include selecting a sludge source; preparing a slurry, where the slurry comprises the sludge source and an electrolyte; adjusting a pH of the slurry, where the adjusting the pH of the slurry results in the slurry having an adjusted pH in a range between approximately 8 and 13; flowing the slurry through a first electrochemical cell, where the first electrochemical cell enables partial oxidation of the sludge via hydroxyl radicals; and flowing the partially oxidized slurry from the first electrochemical cell to a second electrochemical cell for selective conversion, where the second electrochemical cell includes an anode, a cathode, and a catalyst.

A portable renewable energy microgeneration system is disclosed. The system comprises one or more holding tanks that are configured to perform anaerobic digestion on waste in a multi-phase process using bacteria and a controller configured to automatically control the multi-phase process and to re-use the bacteria. The controller re-uses the bacteria by removing at least a portion of the liquid from the waste after anaerobic digestion is performed on the waste and using the at least a portion of the liquid to wet other waste and repeat the multi-phase process.

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. When a fertilizer melt is formed ammoniation is subsequently completed by the specific use of vaporized ammonia. The invention can also be an add-on to commercial production of ammonium salts. The fertilizer produced by the present invention contains more than 8 wt. % nitrogen and preferably 15 wt. % nitrogen. The invention is oriented to be tailored to the biosolids production for individual municipal waste treatment plants in order to keep the fertilizer manufacturing plants of the present invention small with a minimization of logistics and liability.

The system comprises one or more holding tanks that are configured to perform anaerobic digestion on waste in a multi-phase process using bacteria, an odor management system that is configured to remove odors from gas generated during anaerobic digestion, and a controller configured to automatically control the multi-phase process and to re-use the bacteria. The controller re-uses the bacteria by removing at least a portion of the liquid from the waste after anaerobic digestion is performed on the waste and using the at least a portion of the liquid to wet other waste and repeat the multi-phase process.

The invention concerns a method for treating a mixture of wastes (2), the latter being with heterogeneous sizes, shapes and consistencies, the treatment method being characterized in that it includes the following successive steps: Step E1 during which the mixture of wastes (2) is separated into a first fraction of wastes (13) the size of which is smaller than about 180 mm, preferably smaller than 140 mm, via a first series of separation orifices (7, 8) and into a residual second fraction of wastes (14), said first series of separation orifices (7, 8) comprising primary orifices (7) and secondary orifices (8) the size of which is larger than the size of the primary orifices (7) so that the mixture of wastes (2) is first brought into contact with the secondary orifices and then with the primary orifices (7), Step E2 during which the first fraction of wastes (13) is subjected to a composting process so as to compost, at least partially, the contained biodegradable wastes.
