This chapter deals with the green adsorbents and their superiority over the common adsorbents. Economic comparison and brief analysis of common economic perspectives were conducted. Moreover, commercial uses of cost-effective adsorbents and the future perspective for the adsorbent material are covered. The use of such adsorbents can aid the industries to exclude the decontaminated methods of old-terms hence, money and energy could be saved. In order to attain the aim, interaction between the pollutants and material of adsorbents needs to be evaluated and understood. One more future perspective includes the use of green adsorbent which are in collaboration from more than one source (agro-based or natural). Consequently, the researchers have commenced their research to determine the cost-effective adsorbent. Which retains the suitable desorption ability for the adsorption/desorption revolution in sequences.
