This disclosure relates to systems and methods for producing a fuel product from a source of organic matter which includes manure and may include other byproducts. The organic matter is processed by a teeter water feed hindered-bed separator device for substantially separating the animal manure from the other byproducts. The separated animal manure is then subjected to anaerobic digesting to produce the fuel product.

Improved processes and systems for recovering products from a corn fermentation mash. In some examples, a process recovers an oil product, a protein meal product, and a fiber product from a slurry. A process includes the following steps: introducing the slurry into a device with a flexible screen and mechanical agitation to produce a filtrate and a fibrous solid stream; and introducing the filtrate into a three-phase centrifuge to produce an oil stream, a high protein solids stream, and a water with solubles stream. The flexible screen includes a washing nozzle. The slurry is whole stillage from an ethanol process. The three-phase centrifuge is a three-phase decanter. The filtrate is heated before introducing into the three-phase centrifuge. The filtrate is optionally evaporated before introducing into the three-phase centrifuge.

Disclosed herein are methods, systems, and compositions for the pretreatment of biomass within seconds with low inhibitor formation. The pretreatment process is used to convert biomass to a fuel or other useful chemicals by subjecting the feedstock to a rapid retention time under pressure and temperature and/or chemical reactant. The system includes a continuously-operating valve discharge apparatus to discharge pretreated feedstock while maintaining uniform pressure on the pretreatment system.

Reactors, systems and processes for the production of biomass by culturing microorganisms in aqueous liquid culture medium circulating inner loop reactor which utilize nonvertical pressure reduction zones are described. Recovery and processing of the culture microorganisms to obtain products, such as proteins or hydrocarbons is described.

Processes and systems for recovering products from a fermentation mash. In some examples, a process for recovering products from a fermentation mash can include processing a ground corn product to produce a fermentation mash that can include ethanol. At least a portion of the ethanol can be separated from the fermentation mash to produce a whole stillage. The whole stillage can be separated to produce a fiber rich product and a filtrate. The fiber rich product can be hydrolyzed to produce a saccharification mash. The saccharification mash can be processed to produce additional ethanol and a stillage protein product.

A process and system provides for atraumatic preparation of morselized Tissue Particles (TP)s, such as Full Thickness Skin Graft Particles (FTSGPs), cartilage particles and other organ tissue particles, in a liquid medium. The resultant tissue product may be a suspension of Tissue Particles in an aqueous solution and containing highly viable cells and may be rapidly prepared at bedside or in the operating room and conveniently delivered to a patient through a syringe or similar applicator. The morselized Tissues Particles may be used for surgical applications including wound healing, cosmetic surgery, and orthopedic cartilage repairs.
