A process and apparatus for assisting the extraction and processing of
biodiesel oil from organic feedstock includes: providing crushed
oil-bearing organic feedstock meal from which has been extracted a first
amount of biodiesel oil wherein the meal retains a second amount of
entrained oil; forming a meal slurry containing said meal and passing the
slurry to an anaerobic digester; anaerobically digesting the meal slurry
so as to convert said second amount of entrained oil to produce heat,
methane gas, and organic fertilizer or oil-free cattle feed; providing an
electrical generator and employing the methane gas for at least the
production of electricity by burning the methane gas in the electrical
generator which is adapted to convert heat to electricity and re-cycling
at least some of the electricity.
