  • 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: 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.
