synergism established in the digestion medium and the
supply of missing nutrients for microorganisms [5]. So,
using co-digestion of leftover foods, fruit and vegetable
wastes and cow manure is an alternative way to improve
biogas technology. The reactor used in this type of system
would almost certainly need to be operated at mesophilic
temperatures (between 25°
C and 40°
C) to minimize heating
costs. Even if the methane yield was better under
thermophilic conditions (between 55°
C and 60°
C), it would
very likely not be enough to offset the cost of maintaining the
reactors 15° to 30° hotter.
This study aims at the production of biogas from
biologically degradable wastes by co-digestion system.
Various ratios of mixed wastes were prepared to feed the
biogas digester.
