The residual of poultry litter is rising in
parallel with increase in number of poultry farming, and
that waste causes environmental problems due to
difficulties in disposal of waste. Although biochar
production is an alternative technology to solve this
problem, evaluation of biochar is also an important case
for economical sustainability. Depending on the
application area, biochar, that had variable
characteristics, can be produced by different thermal
processes. In this study, the characteristics of products
(biochar and gas) produced by torrefaction were
investigated to reveal the evaluation of products, especially
biochar. The poultry litter was torrefied at low
temperature (300°C) in long residence time (60 minute).
The products were characterized according to heating
value, proximate, ultimate and chemical analysis along
with gas analysis. Characteristic of feedstock was also
determined for comparison. As a result, about 1.5 fold
improvement in properties of feedstock by torrefaction
was observed. The poultry-litter based biochar had the
similar properties with lignite and thus it would be used as
alternative fuel in coal-fired plants for Turkey. Although
heavy metal concentration of biomass is changed in wide
range, the biochar produced from poultry litter had
acceptable amount of heavy metal and adequate content of
nutrient for improvement of plant growth. For that
reason, the application of biochar as soil amendment could
also be proposed.
