accumulation of agricultural waste, air pollution and water
pollution. In addition, using activated carbon from lignocellulosic
biomass instead of fossil sources such as coal will reduce global
warming’s effects. Therefore, the circulation of carbon between
atmosphere and pollutant removal process is merely a carbonneutral
cycle. Apart from being effective in pollutant removal,
lignocellulosic activated carbon is relatively economical, because it
is sourced from agricultural sector wastes and is abundantly
available.
