ABSTRACT

The fruit by-products are considered as environmental waste as they are produced in huge quantities worldwide and are considered as environmental waste as they emit soil pollutant compounds. Therefore, converting them into useful products for industrial applications will have dual objectives in terms of environment and new economic value. Hence, recently, various fruit by-products, such as orange peel (OP), banana peel (BP), tamarind shell, and Indonesian snake fruit peel, have been utilized as a renewable precursor for porous carbon material synthesis for various applications. On the other hand, water pollution by various organic and inorganic metals is a serious environmental issue, which in turn threatens the life of human beings. This is in conjunction with the anticipated water crisis in most of the world regions; hence, wastewater treatment is a mandatory process to protect the environmental life on earth and in turn human life. Thus, in the book chapter, recycling of fruit by-products to valuable added-value porous adsorbents and their exfoliation in wastewater treatment will be reviewed. Additionally, the sustainability of the conversion of wastes to porous adsorbents for high-tech applications will be discussed.
