| 20080199951 | Device for the Storage and Treatment of Biodegradable Wet Solid Waste - The present invention relates to a device for the storage and treatment of biodegradable wet solid waste, especially for vegetarian household waste materials. The device consists of a bucket shaped container with a mesh bottom and a removable cover with a hole at the center. The container is provided with a leachate collection basket at the bottom, which is mounted on an iron stand to hold the device. Openings are provided on the lateral surface of the basket for ventilation. The waste is added to the container from the top by hand lifting the lid.

| 20080318308 | Aerating organic matter container - The present invention consists of a container of arbitrary size, shape, and density configured with ventilating holes of arbitrary size, shape, and distribution to promote air circulation and drainage. In some variations of the present invention a hinged rotatable cover or a supported removable cover prevents the entry of rain into the container. In a closed container organic material will generate dangerous heat build-up that can lead to spontaneous combustion and will present a malingering stench problem as the material decomposes. The present invention alleviates both problems by promoting and facilitating the circulation of air and the drainage of moisture while the organic material is being staged for collection and also provides additional benefits thereby inhibiting the build up of dangerous heat and objectionable fumes and reducing the possibility of spontaneous combustion. The ventilating and drainage holes significantly reduce container weight without significantly reducing strength. Furthermore, the ventilating holes and the drainage holes of the container of the present invention enable and promote evaporation and drying of the organic payload providing additional weight reduction. These additional benefits of the present invention ease the burden of lifting and transporting the waste for both the property owner and collector. | 12-25-2008 |

| 20140349384 | COMPOSTER - In a composter having a horizontally elongated rotating drum, material is fed into the drum through an opening in a stationary end plate having an annular marginal area which overlaps, in sealing relationship, an annular intake end wall of the drum. Material passes through a central opening in an annular exit end wall of the drum, and falls by gravity onto a cylindrical screen which is fixed to, and rotates with, the exit end wall. The annular end walls are in axial register with, and surrounded by, external trunnions on the drum which ride on pairs of supporting rollers. Frusto-conical rings are welded to the end walls, and to the inside of the drum at locations opposite the edges of the trunnion rings to reduce metal fatigue. The exit end rollers allow for axial expansion of the drum. The interior wall the drum is lined with a rubber. | 11-27-2014 |

| 20110281345 | Continuous Flow Worm Farm - An apparatus for the treatment of organic matter with worms, includes a receptacle with a side wall at least a portion of which is downwardly tapering to facilitate compression of organic matter as organic matter is processed, an upper entry aperture for loading the receptacle with the organic matter and worms, a lower discharge aperture for discharging compressed material including castings and organic matter, and a base lid adapted to releasably close the discharge aperture and to permit removal of the compressed material from the receptacle. | 11-17-2011 |
| 20120015430 | SYSTEMS AND METHODS FOR DIGESTION OF SOLID WASTE - This invention relates generally to systems and methods for digestion of solid waste that simplify solids handling. In certain embodiments, anaerobic methane extraction takes place for a period of time (e.g., from 1 to 4 weeks), after which an aerobic composting process begins in the same chamber. The organic waste remains in place and oxygen (e.g., in air) is forced into the chamber for an additional period of time (e.g., from 2 to 4 weeks). At the conclusion of the aerobic phase, the process yields a rough compost product that is stable and pathogen free. The rough compost can be further processed and blended to create high value engineered soils. | 01-19-2012 |
| 20120021504 | AERATED COMPOSTER AND WASTE COLLECTION BIN - An aerated compost and waste collection bin is disclosed. The bin includes a body portion having a bottom, at least one sidewall from the bottom, and an open top forming a container. A perforated tube extends upwards from the bottom of the body portion. At least one lateral vent tube is connected to the perforated tube and the sidewall of the body portion. The lateral vent tube allows air to circulate from outside the body portion of the bin through to the perforated tube. | 01-26-2012 |
| 20120064619 | Device for the Anaerobic Fermentation of Organic Material - A device for implementing anaerobic fermentation having a vertically standing fermentation tank with a fermentation chamber in which organic material can be fermented, a feed device to mix fresh organic material with inoculant and to carry it through to an inlet in the fermentation tank, which is also provided with a cone with an extraction outlet via which fermented material can be discharged and an outlet for biogas, where the device is also provided with two or more return openings via which a fraction of the partly fermented material, located between the inlet and the outlet, is removed from the fermentation tank and is carried up through feed lines between the mixing pump and the inlet that are situated partly and vertically in the fermentation tank. | 03-15-2012 |
