Poultry processing waste conversion to fuel and storable fertilizer

The primary purpose of the work was to study the feasibility of anaerobically digesting sludges produced by poultry processing operations to produce methane gas of quality suitable for use as a renewable energy source and a stable storable dried sludge suitable for use as a fertilizer. Two (2) secondary goals were to show that solar energy is a viable heat source for the process and that an adequate mix can be maintained between the dissolved air flotation and waste activated sludges used as feed materials for the project. With regard to attaining the four (4) specific goals, methane gas is being produced from waste activated sludge and began being collected on March 24, 1982. It has not yet been analyzed for composition but, a small amount was burned in an open collection container. Additional information is being compiled as the project continues. Due to start up problems related to the anaerobic digestion process, no dried sludge has yet been produced and its characteristics therefore have not been studied. Data regarding the dried sludge will also be compiled as the project continues. Data regarding the solar collection and heating system has been evaluated and suggests that solar energy is a viable heat source applicable to the digestion process that could be used either in whole or part to minimize the use of nonrenewable fuels. The material wasted from the first startup indicates that mixing of the two (2) sludges can be maintained since no discernable separation of the waste activated sludge and dissolved air flotation sludge was observed. 8 figures.
