Abstract
A method of producing methane from organic waste includes the following steps: The waste is first shredded. The waste is inoculated first with aerobic microorganisms. The waste is then fermented with the aerobic microorganisms. Then the waste is inoculated with anaerobic microorganisms. The waste inoculated with anaerobic microorganisms is placed in an oxygen free environment. Methane is then evolved from the waste. Preferably the waste is enriched with nitrogen prior to the anaerobic fermentation.
