Animal manure continues to represent a significantly
large and problematic portion of the US agricultural
waste generated yearly.

activated carbon Granular activated carbons made
from pelletized poultry litter have been shown to adsorb
various positively charged metal ions from laboratory-
prepared solutions. The objective of this study was to
develop a conceptual capital and operating cost estimate
using the Superpro Designer process simulation program.
In the study, it was assumed that the activated carbon
manufacturing facility obtains the poultry litter from
various farmers at a cost of $5.50 and $27.50 t−1 for
transportation. The carbon manufacturing facility
processes 20 t of poultry litter per day and converts it
into granular activated carbon for a final carbon yield
of 21.6% (dry basis). This facility operates
continuously, 330 days of the year. Several parameters
were incorporated in the study including equipment
sizing, capital costs and operating costs, such as labor,
utilities, maintenance and equipment depreciation. The
largest contributor to the cost of producing the
activated carbon is the $1,200,000 equipment cost of the
combined pyrolysis/activation furnace, which contributes
about $0.47 kg−1 to the production cost.
-carbon-pellets/">activated carbon pellets for air
filter This study indicates that activated carbon
can be produced by this method at a cost of about $1.44
kg−1.
