Recycling and Upcycling of agricultural waste in dye industry

Abstract

In the present scenario of the rapidly growing world, the wastes are also increasing day by day in large quantity which strongly influences the health of ecosystems and ultimately the human community. Therefore, every agro-industrial sectors have pressing demand toward the safe utilization of agro-materials through recycling of wastes. Agricultural waste materials have little or no economic value and often pose a disposal problem. The utilization of agricultural waste is of great significance. A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber. The removal of color from dye-bearing effluents is a major problem due to the difficulty in treating such wastewaters by conventional treatment methods. Agro-industrial wastes can be a good option to meet the demands of the present generation without compromising the future generations, so there is a gravid need for more attention into the depth of agro-industrial waste utilization and recycling methodologies. The present study focused the several most abundant agricultural waste materials are used for eco-friendly dyes and removal of synthetic dyes from dye bath.
