  • Patent number: 5413432
    Abstract: The present invention pertains to a landfill and sludge processing system. The landfill system comprises a first facility for disposing sludge with waste in a landfill, a second facility for forming a compost pile of yard waste mixed with sludge, a third facility for pelletizing sludge for ultimate use as a fuel, and a fourth facility for processing sludge for use in land enhancement applications. Preferably, there is a generator facility for producing energy from the pelletized sludge. The present invention is also comprised of a method for operating a landfill system. As shown in flow chart form in FIG. 6 , the method includes the steps of transporting sludge to the landfill system disposing a first portion of the sludge with waste in a landfill, disposing a second portion of the sludge with yard waste to form a compost pile, forming a third portion of the sludge into pellets for ultimate use as a fuel and processing a fourth portion of the sludge for land enhancement applications.

  • Patent number: 5297911
    Abstract: The present invention pertains to an apparatus for lifting a container. The lifting apparatus has an elongate member having a first end and a second end and device for lockingly engaging the elongate member to the container, such as a fifth wheel plate attached to the elongate member which lockingly engages with the container. There is a first end attachment connected in proximity to the first end for connection to a mechanism which lifts the container through the apparatus and a second end attachment connected in proximity to the second end for connection to the mechanism which lifts the container through the apparatus. The invention is also a system for tilting a container. The system includes a fifth wheel plate and device for lifting the fifth wheel plate when it is lockingly engaged with the container.

  • Patent number: 5295763
    Abstract: The present invention is a method of controlling this gas migration through the subsurface strata about the landfill. The method comprises the step of installing an extraction well having a zone of influence in proximity to the perimeter of the landfill. Then, there is the step of horizontally fracturing hydraulically the subsurface strata outside the perimeter of the landfill but in proximity to the perimeter of the landfill such that the resulting horizontal fractures in the subsurface strata fluidically communicate with the landfill and the zone of influence of the extraction well. The present invention also pertains to a system for controlling gas migration in subsurface strata about a landfill. The system is comprised of an extraction well which is disposed in the landfill in proximity to the landfill's perimeter. The extraction well has a zone of influence which extends beyond the perimeter of the landfill.

  • Patent number: 5288170
    Abstract: The present invention is a gas-to-energy system featuring beneficial use of sludge in a landfill. The system includes a device for disposing waste in the landfill and a device for disposing sludge in the landfill with the waste. The system also includes a device for collecting gas produced within the landfill from the sludge mixed with the waste and a device for generating electrical energy from the collected gas. The generating device is in fluidic communication with the collecting device. The present invention is also a system for a landfill having a device for disposing waste in a landfill and a device for disposing sludge in the landfill with the waste. The system also includes a device for collecting gas produced within the landfill from the sludge mixed with the waste and a device for separating the gas into components having a common molecular structure. The separating device is in communication with the collecting device. There is also a plurality of containers for containing the components.
