The application of bio-agro waste in industrial production has become extensive. Many industries have embarked in large scale production due to the broadness in the application of the bio-agro waste. This study vividly and succinctly surveyed the different bio-agro waste, its areas of application and its sustainability in industrial production. Several examples of bio-agro waste have been reported. Their relevance in bio-ethanol production has equally been discussed. More so, current research and development in harnessing the bio-agro waste were equally reported, to achieve better economic sustainability. Thus, the study has provided a new circular economic method for addressing the problems associated with bio-agro waste.
