Disclosed is a system for reducing an amount of organic waste and increasing biogas production, combined with a hydrothermal carbonization device having improved energy consumption efficiency. According to an aspect of the present invention, provided is a system for reducing an amount of organic waste and increasing biogas production, the system comprising: a storage tank configured to receive and store organic waste; an anaerobic digester configured to digest organic waste from the storage tank, digest organic matter, and produce biogas; a dewatering unit configured to primarily dewater organic waste discharged from the anaerobic digester; a hydrothermal carbonization device configured to receive and hydrothermally carbonize the dewaterd organic waste; and a filter press configured to secondarily dewater the hydrothermally carbonized product discharged from the hydrothermal carbonization device.

A waste processing plant and method for processing waste, wherein a reduced processed final waste is obtained in powder form that can be reused for other purposes, in addition to allowing the evacuation and storage of gases and/or vapors that are produced during processing so that they can be stored and used for other purposes and thus protect the environment.

A process for transforming a stream of MSW material into feedstock for an anaerobic digester and the resulting generation of biogas and other useful products includes the removal of one or more selected chlorine containing components and the retaining of substantially all paper components. At least 70% by mass of the incoming stream of MSW material is hydrolyzed and subsequently directed to the anaerobic digester.

[Problem] To provide a method for producing useful substances, which converts organic waste containing heavy metals into harmless substances such as fertilizers and soil conditioners by carbonizing organic matter while detoxifying heavy metals. [Solution] The present invention is a method for producing a useful material, said method comprising treating an organic waste in which heavy metals are mixed to produce a carbonized material containing weighed material. The organic waste in which the heavy metals are mixed is treated by dry carbonization of an organic waste to which a Ca component starting material and a SiO.sub.2 component starting material, which are topalmorite starting materials, are added in amounts sufficient to contain the mixed heavy metals in topalmorite crystals; a charcoal-forming step of dry carbonizing the waste, carbonizing the organic waste to form a carbide; the carbide formed in this carbide forming step and the topamolite raw material are charged into a reaction vessel while maintaining the high temperature state in the previous step, and slowly cooled in the presence of water with stirring to form the organic material; a heavy metal confinement step of forming a topamolite crystal mineral in which heavy metals mixed in the organic waste are confined, and forming a slurry in which the carbide and the topamolite crystal mineral are dispersed; and drying or dehydrating the slurry formed in the previous step to produce a useful substance containing a carbide containing the topamolite crystal mineral.

A rotatable drum system includes a frame and a drum rotationally supported thereon. Paddles in an interior of the drum are angularly offset from the longitudinal axis. An eccentric opening offset from the longitudinal axis forms the egress. Mixed solid waste agitated by the paddles while in the drum. Trunnions may support the drum. An actuator may be pivotable with an upper frame relative to a lower frame and the actuator can cause drum rotation irrespective of a position of the upper frame relative to the lower frame. A trunnion assembly with a rocker pivotally coupled to a base thereof via a first axle, enables the rocker to be pivotable relative to the base about the first axle. A second axle may be rotationally coupled to the rocker. A roller may be rotationally coupled to the rocker via the second axle, and configured to support a rotating load.

The present invention provides a decomposition acceleration composition designed to enhance the aerobic decomposition of waste in household trash. The product contains a blend of enzymes, microbial inoculants, nutrients, and other agents that, upon activation by moisture, accelerate the breakdown of waste. This reduces the volume of waste entering anaerobic decomposition phases in landfills, thereby lowering methane emissions. The product is available in tablet, spray, and embedded trash bag forms, making it easy to use, cost-effective, and environmentally friendly.

The present invention relates to a waste processing apparatus, particularly an apparatus for processing used nappies. The waste processing apparatus includes a chamber including a first opening through which a portion of waste is received into the chamber; and a heating member adapted to provide heat to the portion of waste in the chamber. A method of processing waste, particularly a method of processing used nappies, is also disclosed.

Provided are a household toilet waste treatment system and a method of treating toilet waste using the same, the household toilet waste treatment system comprising a solid-liquid separation toilet, a biological treatment apparatus, a sterilization apparatus, and a combustion apparatus. The combustion apparatus complements a slow biological treatment apparatus to allow continuous treatment of the household toilet waste in a unit space without long-distance piping connections.

A household perishable garbage treatment equipment and a use method thereof are provided, relating to the technical field of environmental engineering. The equipment includes a crushing unit, a pyrolysis unit, and a condensation and washing unit. Perishable garbage is crushed by the crushing unit, then the crushed perishable garbage is pyrolyzed into pyrolytic biochar by the pyrolysis unit, and gas produced in the pyrolysis process is condensed and collected by the condensation and washing unit. The household perishable garbage treatment equipment and the use method thereof can effectively treat perishable garbage on the spot, reduce the collection and treatment cost required by traditional perishable garbage treatment modes, achieve carbon sequestration and resource utilization of products, and have significant economic, ecological and social benefits.

An organic waste processing device comprising: an organic matter-receiving container defining an organic matter-receiving chamber; a gas-propelling unit; a gas-plenum chamber in gas communication with the gas-propelling unit; and a grinding assembly at least partially contained in the organic matter-receiving chamber. The grinding assembly comprises a drive shaft and a rotatable blade assembly including a blade support sleeve mounted to the drive shaft and being engaged in rotation therewith. The rotatable blade assembly further includes at least one blade mounted to the blade support sleeve. An inner surface of the blade support sleeve is spaced-apart from an outer peripheral surface of the drive shaft to define a gas flow channel extending longitudinally into the griding assembly and providing gas communication between the gas-plenum chamber and the organic matter-receiving chamber.
