Microwave-assisted quick synthesis of microcrystalline cellulose from black tea waste (Camellia sinensis) and characterization.

Tea wastes generated in the industries during tea production processes show excellent potential to be used as a renewable, abundant, and cheap source for the extraction of microcrystalline cellulose. In the current work, MCC was isolated from black tea waste through microwave heating instead of using conventional heating and avoiding the traditional acid hydrolysis method. Microwave increased the reaction speed significantly and resulted in very quick delignification and bleaching of black tea waste to isolate MCC in white powdered form.

Environmental remediation by tea waste and its derivative products: A review on present status and technological advancements.

The rising consumption of the popular non-alcoholic beverage tea and its derivative products caused massive growth in worldwide tea production in the last decade, leading to the generation of huge quantities of waste tea residues every year. Most of these wastes are usually burnt or disposed in landfills without proper treatment which results in serious environmental issues by polluting water, air and soil. In the recent times, 'waste to wealth' is a fast-growing concept for environment friendly sustainable development.

A critical review on the techniques used for the synthesis and applications of crystalline cellulose derived from agricultural wastes and forest residues.

In order to meet the growing energy crisis of the 21st century, the utilization of bio-based materials has become a field of high research endeavour. In view of that, the present review paper is focused on different techniques that are frequently explored for the synthesis of value-added crystalline derivatives of cellulose like MCC and NCC from agricultural wastes and forest residues. Moreover, a comparative analysis between thermochemical and biochemical methods is carried out for such valorization of biomass considering the mechanism involved with various reactions.
