A portable and modular renewable energy microgeneration apparatus is disclosed that includes at least four modular units. The first modular unit includes a mixing tank and a chopper. The second modular unit includes a buffer tank, a liquor tank, and a pasteurization tank that pasteurizes waste that has been mixed with liquid from the liquor tank by the mixer, chopped into smaller sized components by the chopper, and pre-warmed by the buffer tank. The third modular unit includes a digestion tank that performs anaerobic digestion on pasteurized waste received from the pasteurization tank. And the fourth modular unit includes a gas storage tank that stores gas generated by the waste in at least one of the mixing tank, the chopper, the buffer tank, the liquor tank, the pasteurization tank, and the digestion tank. Each of the four modular units is both portable and modular.

The present invention relates to a method of preparing a wood chip-type organic composite fertilizer wherein the method comprises the steps of: {circle around (a)} preparing wood chips by chipping; {circle around (b)} preparing a liquid organic fertilizer; {circle around (c)} forming an organic mixed solution; {circle around (d)} obtaining colored wood chips by simultaneously immersing the wood chips of the step {circle around (a)} in the organic mixed solution of the step {circle around (c)} and applying hot air to the organic mixed solution to coat the woods chips with colors; {circle around (e)} drying the wood chips to a high temperature to remove moisture formed on an outer surface of the wood chips of the step {circle around (d)} and to make the organic mixed solution penetrate evenly into the wood chips at the same time; and {circle around (f)} packing the dried wood chips of the step {circle around (e)} by weight unit with the measurement thereof on a scale.

A closed-loop, bioregenerative water purification system including a gravity-independent anaerobic membrane bioreactor capable of operating in the presence and absence of gravity, the bioreactor including an anaerobic bioreactor, a first membrane filtration unit, and a second membrane filtration unit, wherein the anaerobic bioreactor is configured to receive organic waste and hygiene water as inputs and break them down into constituent components using anaerobic microbes, wherein the first membrane filtration unit is configured to receive effluent output from the anaerobic bioreactor, return concentrate to the anaerobic bioreactor, and output permeate to the second membrane filtration unit, and wherein the second membrane filtration unit is configured to receive the permeate output from the first membrane filtration unit, separate biogas from the permeate, and output nutrient-rich water.

A readily erectable installation for recycling organic waste into biogas and liquid fertilizer, on an industrial scale, implementing essentially anaerobic digestion processes, is described; the readily erectable installation includes: a cylindrically shaped assemblable enclosure and a pliant collapsible anaerobic digester, suspendable from the enclosure; a compact kit-of-parts for erecting the installation and respective method using the readily erectable installation for recycling organic waste into biogas and liquid fertilizer are described.

Systems and methods for employment in a Zero Waste (ZW) treatment system are disclosed. The ZW treatment system includes a ZW process employing the following individual processes: a separation and extraction process, a blend-heat process, a hydrolysis and acidification process, first-in, first-out (FIFO) anaerobic digestion process, an aerobic boost-blend process, and smart delivery process. A separation and extraction system, a blend-heat system, hydrolysis and acidification system, and a FIFO system performing the ZW treatment process may include a variety of tanks, where each tank may be placed in an enclosure comprising a modular container which, in turn, comprises a modular container system designed for mobility and transportable to remote sites as part of the smart delivery process.

The specification describes a system and process for treating a sludge or slurry to produce biochar. The sludge or in slurry may be digestate produced by an anaerobic digester that receives waste activated sludge from a wastewater treatment plant. In a process, digestate is dosed with metal ions, dewatered, and pyrolized. A corresponding system includes a reactor, a dewatering unit and a pyrolysis unit. In an example, the digestate is air stripped in the reactor and a metal salt is added to it. The metal ions form precipitates in the digestate that remain in the biochar. In some cases, a precipitate such as struvite is formed that also increases the phosphorous content of the biochar. The biochar may be used as a soil amendment, wherein the metal and phosphorous are beneficial to the soil.
