A method of producing fertilizer compositions while producing biogas is disclosed. The method comprises converting an organic material such as organic wastes into fertilizer compositions and biogas. The conversion of the organic material is performed in a fermentation process. In some embodiments, the method comprises preparing a fermenting mixture comprising a starting organic material, a starting bio-stimulant product comprising a plurality of microorganisms, and a starting nitrogen source, and fermenting the fermenting mixture in a fermentation environment for a first time interval to form a fermented mixture comprising the fertilizer composition.

There is disclosed a method of producing a soil remediant from liquid organic waste material in which the liquid organic waste material is concurrently pasteurised and digested by thermophilic aerobic digestion in the liquid phase in a single digester vessel. The organic waste material in the digester is maintained continuously at a temperature of at least 70° C. for at least an hour and the liquid organic waste material comprises at least 70% water and can be pumped. After a period of at least an hour a small amount of pasteurised organic waste material is removed and a corresponding amount of fresh organic waste material is added to the single digester vessel such that the temperature is maintained in a comfort zone of the thermophilic bacteria. In a preferred embodiment the thermophilic aerobic digestion is facilitated by micro-organisms including crenarchaeota. The liquid organic waste material can be combined with a microporous adsorbent. Also disclosed is a soil remediant comprising a microporous adsorbent and liquid organic waste material from the novel method. The microporous adsorbent may be a volcaniclastic sedimentary rock or diatomite or of vegetable origin such as biochar. The microporous adsorbent may be a powder or a granular material and may have particle sizes up to 2000 microns.

A method of processing biological solids includes blending a sludge with calcium oxide and delivering the blended sludge and calcium oxide to a pressurized container; injecting, into the blended sludge and calcium oxide in the pressurized container, an additive capable of exothermic reactions with the calcium oxide; regulating pH in the pressurized container to produce class A biological solids from the sludge; and pumping the blended sludge, calcium oxide, and additive from the pressurized container to a reactor. A system used for this process include sources of calcium oxide and biological solids, an additive injector, and a pressurized reactor.

The disclosed product is an organic commercial 4-0-1 (nitrogen, phosphate, potash) fertilizer or soil mmendment and a feed that can be used as a liquid or dried and used alone or combined with other feeds. Examples of use are feed for black fly larva and all insects, chickens and other foul, all fish, mammals, reptiles, crustaceans; basically, most all living things and microorganisms. This product can be safely used around water because it is suitable as food for fish, reptiles, invertebrates and amphibians.

A fortifier for growth and flowering in horticulture, trees and ornamental plants, aromatic plants and fruit trees, from wastewater from brewer's yeast with a very low protein concentration. The method including the step of: filtered by 80 μm; magnetic treatment of the liquid; addition of 0.1 to 20 g/l phosphate and 10 to 20 g/l glycose. Fermentation is carried out keeping the free amino acid content greater than 0.1%, the content of Mg.sup.+2 greater than 0.1%, total nitrogen, phosphate, and potassium below 3.0%, the content of protein from 0.5% to 1.0% and EDTA from 0.02% to 0.2%, all by dry matter weight; addition of microbes from the environment; at temperatures of 15° C. to 40° C. with gentle agitation, for 24 hours to 30 days; subsequent filtering and pH adjustment. It has been found to be effective in various crops.
