With the progress in technology and population, an enormous amount of agricultural and food waste is being generated throughout the world. In the past, food and agro‐wastes were either burnt off or allowed to rot in fields, but this can be potentially hazardous to the environment. Therefore, approaches with respect to their utilization, reuse, and processing need to be developed to enable the sustainable utilization of feedstock and reduce pollution. Agricultural wastes mainly comprise of cellulosic fibres possessing high fixed carbon content and multifunctional groups. Agricultural waste shows considerable applicability due to its high strength, environmentally benign nature, low cost, and ease of availability and reusability. All these characteristics have been researched upon in the past, in the sector of waste water management for the removal of heavy metals and dyes. Similarly, a variety of food and agro‐waste has been adopted as sources for new drug leads or important phytochemicals with different therapeutic benefits. Agro‐waste can also be employed for enzyme immobilization after proper modification. Apart from this waste cooking oil comes under the category of food waste and can be processed to prepare alternate energy source such as biodiesel. This personal account summarizes the development, processing, and application of food and agro‐waste in the production of biodiesel, environmental remediation, curative medicine, and in the development of biocatalysts, by researchers in our laboratory.

“…d'Halluin et al prepared a chemically modified cellulose filter paper with ethylenediaminetetraacetic acid (EDTA) for heavy metal remediation in water [95]. Cellulose-EDTA composite showed 90-95% removal efficiency for various heavy metal ions including Ag(I), Pb(II), Cd(II), Ni(II), Zn(II), Sn(II), and Cu(II).…”

Biopolymers are polymeric materials derived from biological sources. Due to their renewability, abundance, biodegradability and other unique properties such as high adsorption capabilities and ease of functionalization they have been investigated for several industrial applications including sorption. Polysaccharides especially cellulose, chitin and chitosan are important biopolymers because of their high abundance, wide distribution and low cost of production. This chapter provides an overview of properties, common processing methods, and material characterization of three commonly studied biopolymers namely cellulose, chitin and chitosan. It provides a thorough review on recent developments on utilization of cellulose, chitin, and chitosan-based materials for various sorption applications. Specifically, their application and efficiency in organic dye removal, heavy metals removal, oil and solvent spillage cleanup, and CO 2 adsorption are presented and discussed.

“…77 Color based detection has been demonstrated for detection of metal ions for assessing environmental toxicity. 7 Molecules that have high affinity for metal ions like ethylenediaminetetraacetic acid (EDTA), 78 dithiothreitol (DTT) 74 and polyethyleneimine (PEI) 79 and some proteins like bovine serum albumin (BSA) 2 can be patterned to create capture sites and facilitate analysis on paper substrates through complexation coupled with color-based reactions. Another strategy for colorimetric detection is exploiting NP aggregation.…”
