Food waste is a major problem around the globe, causing excessive food production that ultimately leads to energy waste and global warming. This paper first explores rendering, composting, and anaerobic digestion as possible ways to recycle food waste, specifically animal bones, as alternatives to disposal methods such as incineration and landfilling. Case studies of some countries including the United States, China, and those in the European Union are presented for each method and analyses were carried out on how each method could be practically applied. The latter part of the paper focuses on the waste treatment scheme of South Korea followed by suggested points of improvement, such as shortening the routes for waste collection trucks, and how to realize that.
