Dependence on fossil fuels such as oil, coal, and natural gas is on alarming increase.This has caused the depletion of such resources and necessitated a novel sustainable approach for bioenergy production. Successful implementation of zero waste discharge policy is one such way to attain a sustainable development of bioenergy. Zero waste discharge can be induced only through the conversion of organic wastes into bioenergy. Waste management is pivotal and considering its importance in minimizing the issue and menace of wastes, conversion strategy of organic waste is recommended. Present review focuses on providing a keen view on the potential organic waste sources and the way in which the bioenergy is produced through efficient conversion processes. Biogas, bioethanol, biocoal, biohydrogen, and biodiesel are the principal renewable energy sources. Different types of organic wastes used for bioenergy generation and its sources, anaerobic digestion biogas production and its related process affecting parameters including fermentation, photosynthetic process, and novel nano-inspired techniques are discussed. Bioenergy production from organic waste is associated with mitigation of lump waste generation and its dumping on land, specifically reducing all hazards and negativities in all sectors during waste disposal. A sustainable bioenergy sector with upgraded security for fuels tackles the challenging climatic change problem also. Thus, intensification of organic waste conversion strategies to bioenergy, specially, biogas and biohydrogen production, is elaborated and analyzed in the present article. The persistent drawbacks of the existing organic waste conversion methods are highlighted, giving consideration to economic, environmental, and social development.
