Abstract
The use of organic waste as bio-sorbent has been carried out by many researchers in the world. Furthermore, the utilization of plants for treating wastewater is also commonly found in various environmental applications. Nevertheless, a review of the ability of banana plants (Musa spp.) as bio-sorbent to eliminate gaseous pollutants is rarely found and has not been fully understood. In this paper, lignocellulosic biomass from banana plants (bark, stem, leaves, peels, etc) was identified and reviewed. Sorption potential was discussed and taken from various literature which then evaluated to discuss the potential and ability of banana plants as sorbent material for treating gaseous pollutants. Assessment and measurement methods were also discussed to obtain the best sorbent in removing gaseous pollutants. This research was conducted by reviewing scientific articles that discussed the use of lignocellulosic materials derived from banana plants for absorbing various gases. Almost all articles described the manufacture of adsorbents from banana plants that were used to treat wastewater but not many researchers have tried to develop a commercially adsorbent for gas-shaped pollutants. This research is expected to provide essential information for the readers to develop advanced materials used to control environmental pollution especially gaseous pollutants.

Summary
Gaseous pollutant has high mobility, fast and difficult to control and visualize Some gases such as H2S, N2O contained in biogas or ambient air are indicated to have high levels of toxicity and very detrimental [1,2,3]. Activated carbon pores have sufficient size for gas adsorption and have a large surface area so that a rapid reaction occurs in controlling air pollution [6, 7]. There is no review article discussing and summarizing the potential use of waste from the banana plant as advanced material for the adsorption of gasshaped pollutants. An analysis of the production of activated carbon from banana plants and the mechanisms that may occur in gas removal is carried out. Cellulose and its derivatives are widely used as composites that have been widely studied to synthesis advanced materials such as carbon nanotubes for various purposes [16, 27, 28]
