To estimate the energy
potential of pig manure, we (a) identified and classified a portuguese pig
farm in terms of animal population and husbandry system; and (b) calculated the
farm-specific manure production with its related combustion, syngas and biogas
potential taking into account its chemical composition. The farm has a capacity
for about 50.000 pigs for a total of 4.768 livestock units (LU). It is a closed
cycle pig farm in an intensive production system. The annual production of pig
manure is estimated to be 250 m3/day and annual energy consumption
in 2015 was 483.900 kWh/year of thermal energy and 718.525 kWh/year of
electricity.
