Bamboo as a Source for Value Added Products: Paving Way to Global Circular Economy

Abstract

Bamboo biomass is known for its low cost, abundance, fast growth rate, low weight-to-height ratio, and load-bearing abilities, making it an attractive alternative to materials such as wood, metal, steel, and plastic for multiple applications. Bamboo is traditionally used in handicrafts, food, building, construction, pulp, and paper. The production of energy and green adsorbents with unique properties are a few emerging applications of bamboo. Porous structured, bamboo-based charcoal allows the separation of solute from solvent and can be used to detoxify the air, water, and soil. The surface functional groups can be enhanced during thermal processing, yielding activated carbon products and serving greenhouse gas capturing applications. Nanoparticle particles (Ni0.5Zn0.5Fe2O4 and silver) coated bamboo charcoal has shown microwave and Infrared energy shielding effects. Bamboo-based charcoal also has exceptional medicinal values, is an efficient drug-delivery agent, and has tremendous potential for small and medium enterprises. Bamboo charcoal is also investigated as a toxin adsorber and hence a blood purifier. This review also considers the potential and challenges in using bamboo and its products for many applications that can contribute to a renewable society.
