Biogas has the potential to help reduce global
climate change since the raw materials used in its
production, such as agricultural waste, manure,
municipal waste, plant material, sewage, green waste, or
food waste, are correctly processed to avoid pollution. If
fully exploited, biogas production from current organic
wastes may supply 20% of the world's current natural
gas needs. One challenge encountered in the utilization
of biogas is the occurrence of hydrogen sulfide and water
vapor which decreases its calorific value. In lieu of this
concern, a comparative study for efficiency removal was
conducted for scrubber units between non-rusted vs.
rusted steel wool for H2S removal while silica beads vs.
sponge as absorbents in water vapor reduction. It uses
action research through evaluation in gathering data.
The result of the study reveals that using rusted steel
wool with an efficiency of 105.47% is more efficient
compared to non-rusted steel wool with an efficiency
equal to 55% in hydrogen sulfide removal. Likewise,
silica beads with 41.67% efficiency are more functional
compared to sponge with 0% efficiency in which water
vapor cannot be absorbed from biogas.
