Using food waste as consumable organic resource

Abstract : Food wastage and its accumulation are becoming a critical problem around the globe due to continuous increase of the world population. The exponential growth in food waste is imposing serious threats to our society like environmental pollution, health risk, and scarcity of dumping land. There is an urgent need to take appropriate measures to reduce food waste burden by adopting standard management practices. Currently, various kinds of approaches are investigated in waste food processing and management for societal benefits and applications. Anaerobic digestion approach has appeared as one of the most ecofriendly and promising solutions for food wastes management, energy, and nutrient production, which can contribute to world’s ever-increasing energy requirements. Here, we have briefly described and explored the different aspects of anaerobic biodegrading approaches for food waste, effects of cosubstrates, effect of environmental factors, contribution of microbial population, and available computational resources for food waste management researches.
 ? In contrast, interventions designed to prevent waste focus on the utility of existing goods as a way to improve resource efficiency. ? Waste management-exempt activities would impose the obligation on a smaller number of businesses, and could be introduced as part of the existing regulatory framework. ? It must promote the uptake of existing mainstream technologies and best practices, but also harness and guide the resource saving potential of disruptive innovations.
 ? Incineration of food waste consisting high moisture content results in the release of dioxins which may further lead to several environmental problems. ? This food waste, which is a component of municipal solid waste, is incinerated or dumped in open area which may cause severe health and environmental issues. ? It would be useful to pay more attention to recovery processes for new and emerging materials and technologies, and there is a continued need to support research on problematic legacy wastes, especially from the nuclear industry.
 • We received showed a widespread concern about the proposed absence of planning at a level between the national and the local. • The proposed actions were based on local resources, skills and infrastructure, the analysis produced a bespoke, sustainable solution that was grounded in the local context. • This too will influence the balance of system maps because a failure to acknowledge the views of citizens can compromise the effectiveness of proposed interventions.
 ? It was reported that the use of goat rumen fluid as inoculum at the rate of 8% (v/v) is very efficient for biogas production. ? The pH of bioreactor affects the microbial activity in anaerobic digestion and its efficiency. ? It has been reported that two-stage anaerobic digestion is providing more efficient operation as compared to single stage. ? Microbial community analysis, investigating the composition and behaviour of microbial communities, can be helpful to optimize stable and efficient process operation.
