Odors can arise from an enclosed waste processing system designed to convert solid waste into an aqueous pulp and extract a solid phase and an aqueous phase from the waste. The odors are the result of anaerobic portions of the system in which anaerobic microorganisms convert waste including fatty soils into volatile odor components including low molecular weight carboxylic acids. The action of these microorganisms can be controlled by maintaining the pH, of the aqueous phase common to all portions of the system, at above a pre-selected alkaline pH. Such a pH can be maintained by dosing the aqueous phase in the system with an appropriate amount of one or more alkalinity sources on a timely basis.

[ We claim:] [1.] An enclosed food waste processing system for handling a pulped food waste that produces a solid food waste product and an aqueous waste product from the pulped food waste, the processing system comprising:(a) a holding tank containing at least a mobile aqueous phase that is circulated throughout the processing system;(b) a solid food product extractor having an aqueous waste product outlet in liquid communication with the holding tank;(c) at least one food waste pulper in liquid communication with the solid product extractor, the waste pulper having an input in liquid communication with an outlet of the holding tank;(d) a controller; and(e) a source of an alkaline aqueous treatment which, when directed by the controller, is capable of directing sufficient aqueous alkaline treatment into a structure in the processing system selected from the group consisting of the extractor, an accumulating main system, and a recirculating system in liquid communication with an accumulating system to maintain the pH of the aqueous phase at greater than 10; wherein at least a portion of the enclosed system is anaerobic.
