Abstract: Systems and methods for efficiently collecting and disposing waste from disparate locations within a facility, the method including coupling a series of empty waste receptacles to a tow vehicle and transporting the receptacles to a first location. At the first location, identifying a first full waste receptacle and exchanging it with one of the empty receptacles coupled to the vehicle. The full waste receptacle and remaining empty receptacles are thereafter transported via the tow vehicle to a second location, where a second full waste receptacle is exchanged with one of the remaining empty receptacles. Thereafter, the first and second full waste receptacles are transported to a waste processing location. In some embodiments, the process may be repeated until all the empty waste receptacles on the vehicle have been exchanged with full waste receptacles, at which point the vehicle transports the full waste receptacles to the waste processing location.

Abstract: A system and method for distributing fuel, managing fuel transactions, and determining fuel pricing. The system includes a fuel tank and dispensing systems connected thereto for serving customers. The dispensing systems include a meter measuring a volume of dispensed fuel and a data subsystem that transmits transaction data for fueling transactions completed during a first period. A tank gauge measures an ending volume of fuel at the end of the first period. A management system uses the transaction data to generate a usage report and invoice for the customers based on fuel usage during the first period. The management system further monitors the gauge and determines a price for the ending volume of fuel and a variance based on the measured ending volume of fuel and an expected volume. The variance is used to determine a second price for fueling transactions completed during a second period following the first period.
