1. A method for preventing unsafe buildup of pressure in pressure in at least one anaerobic reactor in a system comprising two anaerobic reactors in recycling communication with one another and at least one aerobic reactor in sequencing batch reactor (SBR) arrangement, while avoiding vacuum in a second one of said anaerobic reactors, each of said reactors being in recycling communication with at least one other reactor, comprising the steps of:
i) feeding a feedstock waste of a specified volume to a first anaerobic reactor; and simultaneously,
ii) transferring a portion of waste of said specified volume from said second anaerobic reactor to said aerobic reactor.
