Patel H. Environmental valorisation of bagasse fly ash: a review. RSC Adv 2020; 10:31611-31621.

Abstract
Worldwide, each year the sugar industry generates bagasse fly ash (BFA) in the process of producing sugar including ethanol and jaggery. With the increasing average value of 2% consumption of sugar per annum, the quantity of solid waste BFA continuously increases and creates environmental problems. The valorisation of BFA is a convenient and sustainable means for decreasing the environmental burden. This paper aims to review the various important analyses and valorisation of BFA. BFA is a porous material and has oxides of several elements, such as silicon, aluminium, iron, sodium and other metals. Based on some of its excellent properties, untreated and modified BFA can represent an important source in different fields. Metals, dyes, petrochemicals, insecticides and other contaminants can be adsorbed using BFA, where the maximum adsorption capacities can be described using different adsorption variables and isotherms. It is convenient and a sustainable resolution to use traditional adsorbents for water treatment. This also decreases the environmental solid burden, eventually reducing greenhouse gas emissions. This ash has been incorporated into different construction materials, including cement and brick in different percentages to enhance their mechanical characteristics and durability, thus maintaining economic and environmental sustainability. Also, several products such as zeolites, silica, briquette catalyst and other important materials, which are promising energy sources, have been prepared using the BFA.

Utilizations of agricultural waste as adsorbent for the removal of contaminants: A review. CHEMOSPHERE 2018; 211:235-253. [PMID: 30077103 DOI: 10.1016/j.chemosphere.2018.06.179] [Citation(s) in RCA: 139] [Impact Index Per Article: 23.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2018] [Revised: 06/28/2018] [Accepted: 06/29/2018] [Indexed: 05/10/2023]
Abstract
In recent years, various industrial activities have caused serious pollution to the environment. Due to the low operating costs and high flexibility, adsorption is considered as one of the most effective technologies for pollutant management. Agricultural waste has loose and porous structures, and contains functional groups such as the carboxyl group and hydroxyl group, so it can be invoked as biological adsorption material. Agricultural waste gets the advantages of a wide range of sources, low cost, and renewable. It has a good prospect for the comprehensive utilization of resources when used for environmental pollution control. This article summarized the current research status of agricultural waste in adsorbing pollutants, which pointed out the influencing factors of adsorption, expounded the adsorption mechanism of biological adsorption and introduced the related parameters of adsorption, proposed the application of adsorbents in engineering including adsorption in liquid and gas phases, at the same time it gave the future development prospect of agricultural waste as adsorbent.
