Phase: anaerobic conditions begin to develop III.Phase: acid phase (facultative and obligate anaerobic bacteria) (pH ≈ 5) IV.Phase: methane fermentation phase (pH ≈ 6.8-8) V. Phase: maturation phase (slowly biodegradable waste) H2H2

17 The amount of biofuel produced on 1 ha of agricultural land is enough for driving around the Globe once…

18 HOWEVER!!! twice as much energy is needed for the production of the biofuel itself!
