Resumen:

Composites obtained from lignocellulosic and chitinous biomasses are promising alternatives as adsorbents due to their compatibility and capacity for pollutant removal. Conventional adsorbents, such as activated carbon, aluminum oxide, zeolite, silica gel, and clays, are used in adsorption processes. However, their manufacturing process is currently leading to mineral scarcity worldwide. The use of chitinous and lignocellulosic materials is advantageous because they are produced from waste, decreasing demand, and exploitation of mineral resources. Biocomposites from lignocellulosic and chitinous wastes provide appropriate mechanical resistance, significant surface area, thermal stability, and biodegradability properties. Furthermore, these agro-food industry wastes are also used to support microorganisms or enzymes. Enzymes such as laccases, esterases, and peroxidases have been reported to degrade the adsorbed compounds, thus preventing contaminants to transfer from one environmental matrix to another. This chapter reviews the entire processing of lignocellulosic and chitinous wastes as adsorbents from raw material conversion to final disposal and reutilization. © 2023 Elsevier Inc.
