Current status of food waste generation and management in China
introduction
2.Recently, the rapid development of the Chinese economy and the growing environmental consciousness of the government and citizens have also led to the rapid development of FW treatment capacity in China
3.This paper aims to provide a comprehensive review of the current state of FW treatment facilities in mainland China and clearly identify future research directions
1.Food waste is a key issue, which has direct environmental, economic and social impacts, in attempts to achieve global food security and good environmental governance
mainbody
FW production characteristics in China
many Possible factors affecting FW production：Parameters including population, GDP, GDP per capita, output of major agricultural products (OMAP), the gross output value of farming, forestry, animal husbandry and fishery
Processes for FW treatment capacity： The China develop quickly，but the capacity in central China needs to be enhanced and more funds invested in facilities by the Chinese government and local governments.
Geographic distribution：An estimated 56.57 million tons of FW was generated in 2015 in mainland China, ranging from 40 to 90 million tons reported in the literature
Characteristics of FW
Chemical characteristics
Biological characteristics
Physical characteristics
FW treatment and disposal in China
Pretreatment techniques
retreatments are applied mainly to separate non-biological impurities from FW and enhance the stabilization of the FW by promoting the biodegradative properties
Anaerobic digestion
Operating parameters
Utilization of biogas
Treatment and use of digestate
Animal feed
Numbers of facilities：FW can be used as an animal feed because of the high energy content generated from the oxidation of organic compounds in the feed
policy
Currently, FW management in China is covered by seven laws, three national standards, and eight ministry standards
.China has made significant progress in specifying FW policies and regulations to promote FW management, such as source-separation, collection, and local treatment.
There are about 12 administrative departments in China responsible for the reduction, reuse, and recycling of FW
Conclusions
FW treatment capacity could increase to 40% in China by the end of 2020. Some technologies or method should be used to deal with the FW
