A method for rotting an organic material includes at least partially controlling a rotting device with a control unit and feeding an organic material into a pivoted rotting chamber of the rotting device, having the organic material rotted in the rotting chamber for a rotting time, turning the rotting chamber by a chamber drive unit of the rotting device, and exhausting the rotted organic material from the rotting chamber after the rotting time. A device for rotting the organic material includes a pivoted rotting chamber for enclosing the organic material. The rotting chamber has a port and a cover associated with the port for opening and closing the port, a chamber drive unit configured to turn the rotting chamber, and a control unit connected to the chamber drive unit and configured to operate the chamber drive unit.

In various embodiments, the present disclosure provides composting materials and methods of making the same.

The invention relates to a composting device for providing compost material from organic material, comprising a drying chamber for receiving organic material to be composted, a heating device located on the drying chamber for heating the organic material located in the drying chamber, a control device for controlling and/or regulating the heating device, and a composting chamber, which is connected to the drying chamber via an opening for material transfer and in which the organic material that has been dried in the drying chamber can be converted into compost material. The invention further relates to a method for providing compost material.

Systems and methods associated with biomass decomposition are generally described. Certain embodiments are related to adjusting a flow rate of a fluid comprising oxygen into a reactor in which biomass is decomposed. The adjustment may be made, at least in part, based upon a measurement of a characteristic of the reactor and/or a characteristic of the biomass. Certain embodiments are related to cooling at least partially decomposed biomass. The biomass may be cooled by flowing a gas over an outlet conduit in which the biomass is cooled, and then directing the gas to a reactor after it has flowed over the outlet conduit. Certain embodiments are related to systems comprising a reactor and an outlet conduit configured such that greater than or equal to 75% of its axially projected cross-sectional area is occupied by a conveyor. Certain embodiments are related to systems comprising a reactor comprising an elongated compartment having a longitudinal axis arranged substantially vertically and an outlet conduit comprising a conveyor.

A rotting device for an organic material includes at least one pivoted rotting chamber, a chamber drive unit, a control unit, and a cover drive unit. The pivoted rotting chamber is configured to enclose the organic material. The rotting chamber has a port and a cover for opening and closing the port. The chamber drive unit is configured to turn the rotting chamber. The control unit is connected to the chamber drive unit and is configured to operate the chamber drive unit. The cover drive unit is connected to the control unit and is configured to be operated by the control unit and move the cover back and forth for feeding and exhausting the organic material into and from the port of the at least one rotting chamber.

This specification describes systems and methods for treating wastewater, for example digestate. The wastewater is separated into a liquid fraction and a solid fraction. The solid fraction of the wastewater is composted. The liquid fraction of the wastewater can be treated, which may result in further by-products. Optionally, at least some of the liquid fraction may be reused in the process. The by-products produced in treating the liquid fraction and/or additional organic solid waste, for example green waste, brought into the treatment facility can be added to the compost. The compost breaks down through aerobic and/or anaerobic digestion processes. Thermophilic conditions may develop in composting piles and increase the rate of evaporation of excess water. When sufficiently dry, the compost may be used as a fertilizer or soil enhancement product.

A composting apparatus comprises a bin, an access panel, an aerator, a water content sensor, a valve, and a composting controller. The bin stores organic materials and compost therein. The access panel, disposed over an opening within the bin, allows access to an interior of the bin. The aerator, disposed within the bin, allows air into the bin to aerate the organic materials and compost therein. The water content sensor, disposed within the bin, senses a quantity of water within the organic materials and compost within the bin. The valve, coupled to a water line, controls a quantity of water added to the bin. The composting controller, coupled to the water content sensor and the water valve, actuates the water valve to control a quantity of water added to the bin based on the sensed quantity of water within the organic materials and compost.
