An organic waste material processing system includes a waste material holding tank and a slurry-producing device configured to process organic waste material into a slurry. A waste processing section has at least one pressurizeable tank connected to the waste material holding tank receiving slurry therefrom. The pressurizeable tank includes a slurry temperature adjusting part and a first hydrocarbon capturing structure configured to capture hydrocarbon vapors produced by the slurry at a predetermined temperature. A hydrocarbon vapor processing section collects captured hydrocarbon vapors from the waste processing section such that an electric power producing apparatus generates electricity using collected hydrocarbon vapor and provides electric power to at least the pretreatment section and the waste processing section. A waste post-processing section is configured to receive processed slurry produce salable organic materials, nutrient enhanced media and recycled water.

A vermiculture unit comprises structural elements defining an interior fillable with organic substance and through which worms for converting the organic substance to environmentally compatible products migrate; a perforated surface for supporting the organic substance; and fixed walls extending upwardly from the perforated surface to a void area located below an uppermost edge of the structural elements, removal of worms from the interior that is below the void area being prevented by the fixed walls. An extractor is insertable into the interior via the void area, for extracting from the interior, solidified organic substance to which the worms have upwardly migrated, allowing grown worms to be separated from the extracted organic substance and collected. In one embodiment, the extractor is an openwork drawer member. In another embodiment, the structural elements are used for vermicomposting while an inclined surface receives worm processed byproducts downwardly discharged through the perforated surface.

The invention discloses an environmentally friendly fertilizer device based on big data, comprising a work box and a crushing space set in the work box, wherein a crushing driving space is set in one end wall of the crushing space, wherein a crushing mechanism is set in the crushing driving space; by turning on a first electromagnetic switch, the kitchen garbage enters the crushing space from the feed inlet, so the kitchen garbage is crushed by the crushing space. A transmission space is arranged in the lower end wall of the crushing space, and a driving space is set in the lower end wall of the crushing driving space; a stirring space is set in the lower end wall of the transmission space; the crushed kitchen garbage enters the stirring space through a circulation pipeline and is stirred by the stirring mechanism, thereby the kitchen garbage can be fully fermented.

Devices and methods are disclosed for the containment and culture of worms, and the preparation of composts, vermicomposts, and castings from organic and inorganic wastes.

The invention concerns a method for treating a mixture of wastes (2), the latter being with heterogeneous sizes, shapes and consistencies, the treatment method being characterized in that it includes the following successive steps: Step E1 during which the mixture of wastes (2) is separated into a first fraction of wastes (13) the size of which is smaller than about 180 mm, preferably smaller than 140 mm, via a first series of separation orifices (7, 8) and into a residual second fraction of wastes (14), said first series of separation orifices (7, 8) comprising primary orifices (7) and secondary orifices (8) the size of which is larger than the size of the primary orifices (7) so that the mixture of wastes (2) is first brought into contact with the secondary orifices and then with the primary orifices (7), Step E2 during which the first fraction of wastes (13) is subjected to a composting process so as to compost, at least partially, the contained biodegradable wastes. Wastes sorting.

In a method for treating waste, in particular domestic waste, comprising the providing of a closed building for receiving the waste, the roof of the building being designed as a semi-permeable membrane, the filling of the building with the waste, the waste being piled into a mound, the performing of a biological drying of the waste with the supply of air, the air exhaust taking place through the semi-permeable membrane, and the discharging of the dried waste from the building, the filling of the building and the performing of the biological drying, and optionally discharging, of the waste are carried out with an unchanged arrangement of the roof, and the filling of the building is carried out by dropping the waste from a continuous conveying device.

Methods, apparatus, and system for a compost system to reduce operator time, reduce power utilization, increase intensity of land use by the compost system, increase efficiency of biological activity in bulk material composted by the compost system, reduce odor production by the compost system, and to reuse water applied to and which may leach out of bulk material. The compost system may comprise an aerated pad, a pivot arm attached to a center of the aerated pad, and a control module. The aerated pad may receive a bulk material to be composted into a compost product. The aerated pad may comprise an air nozzle and a drain to direct water from the bulk material to a water collection system. The pivot arm may deposit the bulk material on the aerated pad. The control module may manage a temperature inside the bulk material using the air nozzle.

A method for improved anaerobic digestion is presented. The method includes mixing a volume of waste material with water to form a feedstock mixture. The volume of waste material includes an initial amount of biomass and the feedstock mixture includes methanogenic bacteria either naturally present in the waste material or introduced artificially. The method also includes introducing one or more promoter substances to the feedstock mixture. The one or more promoter substances are capable of modifying the methanogenic bacteria. Modifying includes stimulating novel enzyme production in the methanogenic bacteria.

The disclosure relates to a food waste recycling appliance having a hollow reservoir which can collect liquid generated during a cycle of operation, drain the collected liquid, and provide an air flow path for the removal of odors.

This disclosure provides a composting system and method. The system comprises: (a) a container configured to contain a composition and comprising (i) insulated walls, (ii) an air intake and (iii) a vent; and (b) a composition contained in the container. The composition comprises aerobic microorganisms, a carbon source and a nutrient source sufficient to support growth of the aerobic microorganisms. The container is sufficiently insulated so that heat generated by aerobic respiration is sufficiently retained in the container to maintain a heat gradient in the container. The container is dimensioned to generate a stack effect that moves air into the air intake, through the composition and out the vent. The moving air provides oxygen to support growth of aerobic microorganisms, making the stack effect self-sustaining as long as a carbon source and nutrients last. The insulation can maintain temperatures in the composting cell sufficient to kill pathogenic microorganisms.
