Nowadays, food waste has gradually become a focus of research globally, and topics related to the influences and consequences of food waste are especially prevalent. Generally, studies about food waste have two main characteristics. Firstly, many of them are conducted in developed countries and emphasize household waste and food consumption (Wenlock et al., 1980; WRAP, 2009; WARP, 2010). Compared with the situation in developed countries, fewer studies about food waste in developing countries are available, and most of them focus on the stages of harvest and storage. Secondly, the focus of this research varies from the amounts and causes of food waste (Kantor et al., 1997; Rebecka and Annika, 2004; Cuellar et al., 2010), the technologies and policies to reduce food waste (FAO, 1981; Christer, 2002; Lyndhurst and WRAP, 2012), and the recycling of food waste (Francesca et al., 2015; Karmee and Sanjib, 2016; Visschers et al., 2016).
