A renewable energy microgeneration apparatus is disclosed that includes a mixing tank that mixes waste with a liquid, a buffer tank that receives and pre-warms the mixed waste, a pasteurization tank that pasteurizes on the pre-warmed mixed waste, a digestion tank that performs anaerobic digestion on the pasteurized waste, a de-watering device that separates liquid digestate and removes salt from the liquid, sensors that measure salinity and biogas quality, and a controller. The controller causes the transfer of digestate from the digestion tank to the pasteurization tank to the dewatering device, causes the de-watering device to separate the liquid and remove the salt from the liquid, monitors the salinity of the liquid and the quality of biogas using the sensors, and causes the mixing of the liquid with the waste and adjusts the feed rate of the waste to reduce the salinity of the waste and increase methane production.

A method for manufacturing a growing medium, the method including feeding biomass and biochar to a crusher and feeding a probiotic solution and a mixture obtained from the crusher, having a particle size of less than 25 mm, to a conveyor. The particle size of the biochar is 0.01-2.5 mm and the biochar is used in an amount of 0.05-7 vol-% of the biomass. The probiotic solution includes lactic bacteria, photosynthetic bacteria and at least one yeast, and the probiotic solution is used in an amount of 0.1-2 vol-% of the biomass. Additionally, a distillate obtained from a manufacture of the biochar is fed to the crusher and/or the conveyor.

The present invention relates to a method for solubilisation or hydrolysis of Municipal Solid Waste (MSW) with an enzyme blend and an enzyme composition for solubilization of Municipal Solid Waste (MSVV), the enzyme composition comprising a cellulolytic background composition and a protease, lipase and/or beta-glucanase.

The present application provides a method for fully recycling kitchen waste by using Hermetia illucens L. and aerobic microorganisms. The method includes first performing solid-liquid separation on the kitchen waste; then using the filtrate obtained through separation to feed young larvae of Hermetia illucens L. to convert salt in the filtrate into body fluid of Hermetia illucens L. in a larval stage, and using the kitchen waste filter residue to feed 2.sup.nd-6.sup.th-instar larvae of Hermetia illucens L. respectively; separating insects and insect feces residue in a timely manner, so as to reduce a salt content of insect feces and improve transabdominal transformation efficiency of Hermetia illucens L. and quality of the insect manure; and finally implementing full resource utilization through aerobic composting and insect drying and sterilization treatment.

The invention provides an efficient system for treating livestock waste, particularly waste from cattle or pig farming. The new facility and method employ special transfers of slurry streams through ASBR, SBR, and a unique pretreatment reactor, resulting in treated water, quality compost, and biogas.

A sulfonated lignin as a by-product of papermaking wood pulp/urea-formaldehyde (UF) fertilizer and a method for preparing the same by a reactive extrusion and granulation process are provided. The method includes: mixing a hydroxymethylated sulfonated lignin solution with a hydroxymethyl-urea solution followed by feeding into a reaction-extrusion integrated machine and reaction at a preset temperature for a preset time; subjecting the reaction mixture to extrusion through a twin-screw extruder to obtain a strip product; and drying the strip product followed by granulation to obtain a sulfonated lignin as a by-product of papermaking wood pulp/UF fertilizer columnar particles. Sulfonated lignin molecules are introduced to the main chain of the UF macromolecules to reduce the polymerization degree and crystallinity of the UF fertilizer, so as to regulate the nitrogen release rate.
