Method for producing a fertilizer or herbicide from a whole stillage byproduct produced in a corn dry-milling process for making alcohol and system therefore is disclosed. In one embodiment, the method includes separating the whole stillage byproduct into an insoluble solids portion and a thin stillage portion. Thereafter, the thin stillage portion can be dewatered to provide a water soluble solids portion and a dewatered protein portion, which may be optionally dried. The protein in the resulting protein portion can serve as a nitrogen source and sulfur containing amino acids can serve as a sulfur source, which can be desirable components in fertilizers and herbicides. To that end, the resulting protein portion directly may be sold and/or used as a fertilizer or herbicide or can be combined with other components to provide the fertilizer or herbicide.

Primary leachate is used as a plant growth stimulant. A fermentation medium is fermented with a microbial culture in a bioreactor to produce a primary leachate comprising microorganisms derived from the microbial culture and/or naturally occurring microorganisms. The primary leachate is isolated from the bioreactor, diluted with water, and used to irrigate plants to reduce bacterial diversity and stimulate beneficial microorganisms in the rhizosphere around the plants. The fermentation medium may be organic waste, preferably food waste. A secondary leachate may also be used as a plant growth stimulant. The primary leachate is used to culture black soldier fly larvae with a substrate in a secondary processing bioreactor under suboptimal culture conditions, thereby producing secondary leachate. Melanin is extracted therefrom by acid precipitation. The secondary leachate is then diluted with water and used to irrigate plants, reducing bacterial diversity and stimulating beneficial microorganisms in the rhizosphere around the plants.

Processes, systems and equipment are for treating a digestate resulting from the thin stillage of a bioethanol plant. They can include a decarbonizer system to reduce the carbon and water footprint in an ethanol plant and associated biogas plant by treating a digestate stream resulting from a thin stillage digester. The treatment includes heating the digestate stream to decompose ammonia bicarbonate contained in the digestate stream into ammonium and bicarbonate; and contacting the heated digestate stream with air so that a first portion of the ammonia is desorbed from the heated stream to mix with the air.

The present development is a method for producing a high concentration free amino acid soy hydrolysate composition and a method for using the resulting hydrolysate composition. The high concentration free amino acid soy hydrolysate is used to enhance the microbe population found in soil and wastewater. The enhanced microbe population can promote plant growth, particularly for use in brownfields and similar reclamation sites or on turf grasses, and can promote the digestion of sewage solids.

Disclosed are malt sprouts fraction extracts, their process of preparation and their use as a biostimulant agent.
