The present invention relates to a self-deodorizing composting system, comprising an outer membrane, an inner membrane, an air-ribbed cage and a deodorizing base, wherein two deodorizing bases are provided; the outer membrane and the inner membrane are held by the air-ribbed cage, with both ends of the outer membrane and the inner membrane respectively fixed to the two deodorizing bases, whereby a closed space is formed between the outer membrane and the inner membrane; the inner side of the inner membrane is used for placing the composting piles, with the malodor and water vapor generated from the composting piles entering into the closed space formed between the outer membrane and the inner membrane through the inner membrane, so that the water vapor is condensed into the water in the closed space, and the malodor molecules are absorbed and dissolved into the condensed water, thus forming the waste water which falls along the inner side of the outer membrane and the outer side of the inner membrane to the bottom of the deodorizing bases and is discharged from the deodorizing base. Comparing with the prior art, the system in the present invention has a simple and detachable structure, and can isolate and remove the malodor and the water vapor generated when the biomass waste is composted.

A method for operating a composter device including directing exhaust from a composting container to a reservoir by way of a first fluid pathway, directing ambient air to the reservoir by way of a second fluid pathway, and mixing the exhaust from the first fluid pathway and the ambient air from the second fluid pathway.

Today's funeral practices are unsustainable, toxic, and polluting. Both cremation and the manufacture and transport of caskets, grave liners, and headstones emit greenhouse gas emissions into the atmosphere. In fact, the very last thing that most of us will do on this earth is poison it. As a response, a system and method called recomposition that gently and naturally returns humans to the earth after death.

The present application provides a reactor with an inclined bottom gas-inlet for aerobic fermentation. A fermenter is provided with a circular inner tank, end covers and a jacket. An airtight fermentation space is formed in the fermenter by the inner tank, an upper end cover and a lower end cover. A feed opening and an exhaust outlet are arranged at an upper part of the fermenter, and a discharge opening is arranged at a lower part of the lower end cover of the fermenter. An energy-saving stirrer is mounted in the fermenter. A plurality of air chambers are arranged at an external wall at the bottom of the inner tank of the fermenter and are within the jacket. A plurality of aeration nozzles are defined on an inner side of each air chamber, and the aeration nozzles are disposed next to the inner tank.

A digester system comprising a primary digester tank containing a primary feed material portion, a secondary digester tank containing a secondary feed material portion, a first conduit connected between the primary digester tank and the secondary digester tank to define a primary tank lower opening within the primary digester tank and a secondary digester tank lower opening within the secondary digester tank, and a flow control valve configured to allow or prevent flow of fluid through the first conduit. When the flow control valve is configured to allow flow of fluid through the first conduit, a portion of the primary feed material portion flows from the primary digester tank to the secondary digester tank to form the secondary feed material portion.
