NOVELTY - A waste processing system is coupled with an agricultural facility (20) to receive the agricultural waste. The waste processing system removes water from agricultural waste to produce biomass. An energy generation system produces quantity of energy by utilizing the biomass. A biofuel facility is coupled with the energy generation system to receive and utilize the quantity of energy. A wastewater treatment system receives and treats wastewater to provide treated water to the agricultural and biofuel facilities, energy generation system and waste processing system.    USE - Closed loop biomass energy system for providing energy from agricultural waste.    ADVANTAGE - The environmental harm is reduced. The feasibility for using the source of energy is enhanced.    DETAILED DESCRIPTION - The biofuel facility produces the biofuel by utilizing the steam energy. The agricultural facility includes the dairies. A vacuum conveyance system (25) delivers the agricultural waste to the waste processing system. The vacuum conveyance system includes a valve pit (3112) for collecting the agricultural waste, and a main waste line (3113) for conveying the agricultural waste from the valve pit to a vacuum station (3120). The waste processing system removes water from the agricultural waste by homogenization, electro-coagulation, decanting, drying and horizontal screw pressing processes. The energy generation system includes a fluidized bed thermal oxidizer having a feed system that receives and feeds the biomass into a fluid bed combustor. The fluid bed combustor includes a fluidized bed and a bed recycle system to produce steam from a superheated steam generator. An economizer, a bag house, and an exhaust stack are used to remove a portion of pollutants from an emission produced by the fluid bed combustor. The wastewater treatment system performs primary and secondary wastewater treatment processes using Algaewheel (RTM: Wastewater treatment technology) for producing the algae biomass. The energy generation system produces the quantity of energy by utilizing a portion of the algae biomass. INDEPENDENT CLAIMS are included for the following:    (1) method for providing energy from agricultural waste; and    (2) method for preparing biomass, which involves electro-coagulating the agricultural waste to separate solids from water in the agricultural waste. The removed solid is dried to reduce residual water content in the solid. The agricultural waste is collected using the waste vacuum system from the agricultural facility.
