Biorefineries development from agricultural byproducts: Value addition and circular bioeconomy

The increase in the human population in the world, industrialization, and rapid urbanization cre-ates a big challenge for the agricultural revolution. Hence, to enhance the crop's productivity modern agricultural technology, hybrid seeds; management of full irrigation facilities, and the use of various fertilizers, and pesticides are being adopted. Though such advanced techniques en-hance productivity, they also produce a huge amount of agro-waste. The proper waste manage-ment of such wastes is a headache for the farmers due to the lack of dumping lands, proper trans-portation, removal facilities, and lack of planned utilization. Since direct burning of the wastes do air, water, and soil pollution, a systematic utilization of these cheap wastes for the development of value-added products and chemicals will promote a clean and healthy environment for the bi-otic and abiotic components. A proper, efficient, and effective treatment system can break down waste biomass into simple forms and can be easily consumed by our natural and engineered mi-crobial systems to produce bio-chemicals and bio-fuels. Value-added products from agro wastes are now needed every hour as far as the sustainable production of energy and biochemical is an important concern. Agro-waste utilization-based biorefineries can provide a big pillar for the de-velopment of a circular bio-economy. The review emphasizes the value-added products gener-ated from agricultural byproducts/waste residue's utility, towards sustainability and a clean envi-ronment.
