Field harvested culture mix is used to inoculate organic waste and produce an inoculated waste material, where the field harvested culture mix includes soil derived microbes. The inoculated waste material is shredded to produce shredded inoculated waste material which is fermented the shredded inoculated waste material for at least 7 days. Contents from the fermenter are then transferred into a dewatering device to produce dewatered contents which are then separated into soluble and suspended products.

Processes for manufacturing organic fertilizer products, such as liquid and solid organic fertilizer, from animal manure are disclosed, together with the fertilizer products produced therefrom.

A biogas plant produces both methane and liquid fertilizer by fermenting biomass. The plant includes a fermenter, a percolate tank and a sanitation tank located inside the percolate tank. Dry fermentation takes place in the fermenter and generates methane and a percolate. The percolate is circulated between the fermenter and the percolate tank. Percolate that is returned from the percolate tank to the fermenter is sprinkled over the biomass. A portion of the percolate is transferred from the percolate tank into the sanitation tank. The percolate in the sanitation tank is sanitized by heating to a Celsius temperature between 45 and 65 for a period of at least five days. The percolate in the sanitation tank is heated using both a heating device in the sanitation tank as well as heat generated from a thermophilic fermentation reaction occurring in the percolate tank. The sanitized percolate is used as liquid fertilizer.

The invention relates to a method for processing biological substrate, comprising the steps of: a) introducing the biological substrate into an apparatus for dry fermentation, b) carrying out dry fermentation to recover methane, forming fermentation residue, c) transferring the fermentation residue obtained in step b) to an apparatus for solid-liquid separation, d) carrying out solid-liquid separation of the fermentation residue, forming a fermentation residue solid phase and a fermentation residue raw liquid phase, e) transferring the fermentation residue raw liquid phase obtained in step d) to an apparatus for separating solids, f) carrying out separation of solids from the fermentation residue raw liquid phase, recovering a fermentation residue liquid phase, g) introducing the fermentation residue liquid phase obtained in step f) into an apparatus for wet fermentation, h) carrying out wet fermentation to recover methane, forming liquid fermentation residue, i) returning at least some of the liquid fermentation residue formed in step h) as inoculum to the apparatus for dry fermentation.

Various embodiments are described herein for an apparatus that implements one or methods for producing compost. The method may include receiving waste in a composting apparatus, the waste having a first moisture content; pre-treating the waste to produce pre-treated waste; storing the pre-treated waste into a storage chamber for a pretreatment time period to produce stored waste; and composting the stored waste in a compost chamber to produce a batch of output compost having a second moisture content, wherein the second moisture content is less than the first moisture content.
