Abstract :

Introduction: Currently, unsegregated food waste in our country is one of the environmental and economic problems. while in some countries, there are some precise superseded and retributive legal rules to prevent the release of not separated household or commercial food waste, thus, refusal these orders are accompanied by financial or social penalties.Materials and Methods:  The last 5 years literature review on the management of these kind of wastes have been reviewed. Results: There are over 1,900 known species of edible insects. Cockroaches, caterpillars, bees, flies, and ants are the most popular. In this article, the use of these edible insects, which are used in some countries for human consumption, extraction of various sources such as protein or animal feed, has been mentioned and discussed as a solution for the use of these nonseparated food wastes containing plastics, which consequently, could be the aim of creating a green economic cycle for returning to nature and make economic exploitation.Results: Totally, the use of insects as a part of natural life cycles and as food and feed, especially in some developed and developing countries, has become one of the cost-effective and economic solutions to adjust the problem of non-separated food waste.Conclusion: Considering the country's economic and currency conditions, this can be an alternative solution, and these insects can be used as a source of protein for food and feed, or be used for biodiesels or agricultural purposes.
