An anaerobic biogas plant for the digestion of fresh organic digestion substrate. The digester having an entry section with an inlet at a first end, a rear section at a second, opposite end, and a middle section arranged between the entry section and the rear section. The digester further includes a stirring unit comprising a shaft extending in the direction from the first end to the second end and having at least one agitating arm for mixing the substrate within the digester. The middle section of the digester includes a main outlet and the rear section includes an additional outlet. The digester further includes a separate return line leading from the additional outlet back to the entry section of the digester for allowing a direct return of a minor fraction of digested substrate removed from the rear section back into the entry section of the digester.

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 compost bin module for aerobic decomposition of organic matter. The module is in the form of a container comprising a free-standing portable structural frame for placement on or above the ground. It further comprises removable sidewalls, and an open top and open bottom. Each of said removable side walls insertable into the structural frame and laterally restrained thereby. The structural frame comprises at least three spaced-apart posts, at least an equal number of structural members spanning between and interconnecting the posts, each of the structural members spanning between two adjacent posts at or near their base.

An entirely water-based, energy self-sufficient, integrated in-line waste management system is provided for comprehensive conversion of all organic fractions of municipal and wider community waste to fuels suitable for use in transportation, with all solid residues converted to high nutrition compost. The system is based on a combination of pre-treatment, involving alkaline hydrolysis and saponification; three-way separation of the pre-treated waste into different streams that are each directed to suitable further processing including fuel production; which includes biodiesel generation in a continuous-flow catalytic esterification unit, and anaerobic digestion to produce methane or other small molecule biofuel. Remaining solids are converted to compost in a quasi-continuous process.

The invention is directed to a process and equipment for use in a process to bacterially decompose organic waste to a dry composted end material wherein organic waste is composted in a composting tank in the presence of oxygen and aerobic bacteria to obtain a wet composted material. The wet composted material is partly removed from the composting tank and dried such to lower the water content of the composted material to obtain dry composted end material.
