The technical, environmental and economic analysis of generating electricity and/or heat together with bio-char
from poultry litter (PL) waste is the subject of this study. For this analysis, the process simulation software ECLIPSE
is used. Modelling and simulation have been conducted over the configuration: combined updraft gasification and
pyrolysis process integrated with an Organic Rankine Cycle (ORC). The facility will initially be capable of
processing 1500kg of PL waste at 30% moisture content every hour. The expansion plans of the facility are underway
to deal with 3000kg of PL waste per hour. Based on the results achieved, the key technical and environmental issues
have been examined. Finally, an economic evaluation of the system is performed. The ECLIPSE simulation shows
that the yield of biochar produced in the updraft gasifier is around 415kg per hour and the producer gas is about
2052m3/hour with a calorific value of 4.45MJ/Nm3. Gross electric power generated by the ORC system is 391kWhe.
Recovered low grade heat for space heating is estimated at 1822kWhth.
