  • Patent number: 9428333
    Abstract: Systems and methods for installing a compressed natural gas housing apparatus to a vehicle are disclosed. The housing apparatus is configured to be retrofitted to existing cab liners used on refuse vehicles. The complete installation of the housing apparatus and roof liner are disposed below the roofline of the refuse vehicle. The housing apparatus can be configured to contain a variable number of compressed natural gas tanks. The housing apparatus is installed such that the length of the gas pipeline and electrical wiring connected to the apparatus from the vehicle engine and controller is minimized. The location of housing apparatus provides the additional safety of minimizing the exposure of the gas tanks to falling debris or prevent possible contact with the compressed natural gas tanks being damaged as vehicle travels under bridges, other low objects, or contact in the event of a rollover accident.

  • Patent number: 8542121
    Abstract: Systems and methods for authorizing a waste item to be removed from a site. In one embodiment, a waste collection vehicle includes a reader configured to obtain identification information from an identification tag associated with the waste item. A transceiver associated with the vehicle is configured to: receive the identification information from the reader, wirelessly transmit the identification information to a remote computer for processing, and wirelessly receive an indication of whether the waste item should be collected and removed by the waste collection. The received indication is based on at least one hazardous characteristic associated with the identified waste item, a determination that the waste collection vehicle is authorized to collect the waste item having the at least one hazardous characteristic, and a determination that a driver of the waste collection vehicle is authorized to collect the waste item having the at least one hazardous characteristic.

  • Patent number: 8357232
    Abstract: The present invention relates to a system and method for the separation of gaseous components from gaseous mixtures in order to control emissions and treatment of the gaseous components. In one embodiment, the system makes use of a fan or gas moving device to first impose centrifugal forces on gas streams as the gas moves from the center of the fan toward the periphery of the fan housing. Heavier gases are forced to the outer regions of the fan housing while lighter gases remain closer to the fan axis. The heavier gases and lighter gases exiting the fan housing flow into a duct at different flow rates, and the heavier gases are diverted from the larger volume gas streams and then processed.

  • Patent number: 8287625
    Abstract: Embodiments of the present invention are directed to systems and methods for treating landfill gas using landfill leachate. In one embodiment of the present invention, a method includes receiving landfill leachate from at least one of a plurality of sources, and pretreating the landfill leachate to adjust at least one chemical property of at least one component of the landfill leachate. The leachate contacts landfill gas, so that at least one component of the landfill gas chemically reacts with at least one component of the landfill leachate to form a spent landfill leachate and a treated landfill gas. The method also includes recycling a first portion of the spent landfill leachate, recirculating a second portion of the spent landfill leachate to at least one of the plurality of sources, and subjecting the treated landfill gas to flare.
