Utilisation of agro-industrial waste for sustainable green production: a review

Agro-industry generates large amount of waste with diverse characteristics. The accumulation of agricultural waste is in the excess of 2 billion tons worldwide. This makes it imperative to investigate how agro-industrial waste utilization can be advanced to the next phase to maximise benefits from the sector. Improper management of these wastes leaves undesirable footprints in environment as well as on the economic health of many nations. In this direction, development of proper clean and green waste management approaches is the need of the hour, firstly, efficient conversion of wastes to value added products, by-products within affordable treatment costs and secondly, impact assessment on soil quality and productivity. This review fills the existing research gap on how agro-based waste can be productively harnessed. The review comprehends elaborately the industrial innovations and technology for recovery of agro-industrial wastes, which has triggered high resource efficiency, sustainable production and safe disposal.
