Production and Utilization Stage Analysis of Biogas: Case of IZAYDAS Plant

Öz

This
study investigates size and operating condition effects on energy production
efficiency, greenhouse gas (GHG) mitigation and economic potentials in
production and utilization stages of a biogas system. In IZAYDAS plant,
efficiencies of biogas production and electricity generation are found to be 28
% and 20 % independently from operating scheme, respectively.  When these results are compared to a small
capacity plant without an automatic control keeping the biogas system at or
close to favorable conditions for fermentation and a lower quality electricity
generator, both biogas and electricity production efficiencies are found to be
lower showing the importance of operating conditions and size on energy
production efficiency. Organic waste processing is the major contributor to the
GHG mitigation potential followed by fossil electricity and then chemical
fertilizer replacement. Economically, liquid fertilizer is the major source of
income due to its high amount followed by solid organic fertilizer and
electricity sold to the grid. When different utilization paths are investigated
for biogas, it is found that direct utilization of biogas has a higher GHG
mitigation potential and favorable energetically.
