In 2013, 11.5% of the electricity produced from RES was from
biomass-biogas units. However, the potential of biomass-biogas
units is considerably great and this is the main focus of this work.
The first anaerobic digester in Cyprus was installed in 2007 for the
treatment of pig waste. According to the Department of Environment
of the Ministry of Agriculture, Natural Resources and Environment,
today, there are 13 biomass-biogas units in Cyprus, of
which 12 units use anaerobic digestion (AD) (Fig.1) and 10 units use
animal waste as their main substrate. These 10 units are connected
with the power distribution grid of the Electricity Authority of
Cyprus (EAC) supplying their output. Noteworthy is that, 8 of the
AD units, use mainly piggery waste. In Cyprus there are 78 pig
farms (2011) and thus the potential to use AD for biogas production
from piggery waste is highly attractive.
