A product, including digestate, that has been pasteurized through thermal hydrolysis, thermal alkaline hydrolysis, or thermal carbonization is cured to enhance its marketability. Variations of this disclosure include embodiments where pasteurized material is inoculated to further enhance marketability where the inoculation is performed by injecting a fungicide, other means of inoculation by injecting beneficial microorganisms to produce characteristics in digestate that are anti-fungal or produce suitable enzyme cofactors or nutrients to stabilize digestate, injections of vitamins to enhance the ability of plants grown using select digestate to thrive in adverse conditions, injection of chemicals to enhance the ability of digestate to retain heat and prevent freezing during wintry conditions, or any combination thereof. Other embodiments include using recycled waste heat generated from wastewater treatment or another process or solar energy for accelerating the drying process which occurs before, during or after curing.

An under-sink composting device configured to operably couple with a garbage disposal. The composting device includes a waste separator for separating solid waste from liquid in an organic waste material.

A system for the continuous production of a liquid fertilizer is provided. The system operates by feeding a compost material at a continuous rate to an extractor. The extractor uses a belt system to convey the compost along a path. Sprayers above the belt spray water or similar liquid water based substance onto the compost. The water absorbs nutrients and other components of the compost and is then drained through the belt to a receptacle to store the liquid fertilizer.

A compost leachate distribution device includes a composting chamber for receiving material to be composted and a leachate collection chamber for collecting, via a leachate fluid path, leachate generated during composting in the composting chamber. The device has a leachate mixing arrangement a first inlet for receiving a flow of water, a mixing chamber to which the first inlet leads for mixing water with leachate to form a water/leachate mix and an outlet leading from the mixing chamber to the exterior for exit of the water/leachate mix, wherein the leachate mixing arrangement has dosing means for controlling a rate of flow of leachate from the leachate collection chamber into the mixing chamber.

A sewage sludge-to-resource recycling system of circulation-type is provided for recycling sewage sludge as organic waste into a useful product. The sewage sludge-to-resource recycling system of circulation-type comprises: dehydration means to dehydrate sewage sludge to form a raw material; primary fermentative treatment means comprising a horizontal cylindrical shaped fermentative treatment container configured to be rotated about a central axis thereof; raw material supply means provided on the inlet end side of the fermentative treatment container and configured to receive the raw material from the dehydration means and supply the received raw material into the fermentative treatment container; primary fermented product discharge means provided on the discharge end side of the fermentative treatment container and configured to discharge the primary fermented product outside the fermentative treatment container: secondary fermentative treatment means to receive the primary fermented product from the primary fermentative treatment means, and additionally ferment the received primary fermented product to produce a secondary fermented product having a second set water content value or less, the second set water content value being less than a water content of the primary fermented product; carbonization means to receive the secondary fermented product from the secondary fermentative treatment means, and subject the received secondary fermented product to carbonization treatment to produce a carbide; mixing means to receive the secondary fermented product from the secondary fermentative treatment means and the carbide from the carbonization means, and mix them together to produce a mixture; and water content measurement means to measure the water content of the primary fermented product discharged from the primary fermentative treatment means; wherein the mixing means is connected to third distribute and supply means, the third distribution and supply means being configured to distributively supply at least part of the mixture to the raw material supply means and/or third useful resource processing means to perform processing into a third useful product of a third form.
