Food waste and the food-energy-water nexus: A review of food waste management alternatives

Large quantities of food produced are wasted around the world. Production of wasted food has a major impact on resources, but little is known about the energy and water consumed to process food waste. Here we will explain food waste in Food - Energy - Water (FEW) relationship and analyze the FEW effect of Manufacture of Unsalted Food and Management of Food Loss and Waste Difference. We found that various food waste management options such as waste prevention, landfilling, composting, anaerobic digestion and incineration provide a viable path for the impact and opportunity of FEW. In addition, comprehensive and sustainable management of food waste involves multiple governance levels and individual consumer-level mechanisms and entities. In order to solve the complicated garbage problem, we propose a "food waste system" method that optimizes resources with FEW relational expressions. Such a framework will promote the efficient use of energy and water in food production that reduces the externalities of pollution, creates opportunities from renewable energy and nutrients while minimizing wasteful food volume Can be used to develop strategies such as. Characterization of the impact of FEW's relationship to waste food, including a description of dynamic feedback behavior, presents key research gap and future research priorities. For large-scale decision-making, a more comprehensive understanding of food waste and its management in relation to FEW is necessary, especially after disposal related to water.

As the demand for water, energy and food continues to increase, the relationship approach has recognized the need to use resources more efficiently while seeking policy support among sectors, so water - energy - food - related Management is an important element for developing a green economy. Consistent Green Growth However, the governance of the water - energy - food sector is usually independent and focus is limited on the interaction between them. As a result, operation in a narrow range is impossible to reduce the relevant pressure. Nevertheless, governments around the world are leading the development of innovation policies that create interdependence and synergies between affiliates while reducing trade-offs in green economic development.
