thanks to the solid waste boom gradually released by waste classification, the treatment of restaurant and kitchen waste has begun to accelerate in recent years

large amount and wide range of food waste is the top priority of domestic waste treatment. The rapidly growing population base has also increased the amount of food waste. From 2014 to 2018, the domestic waste transfer volume increased by about 22.16% year-on-year, and food waste accounted for more than 50% of domestic waste. Some experts predict that the total amount of food waste collected separately in China each year is about 20million tons to 30million tons, and the daily output will exceed 500000 tons. The situation of food waste treatment is grim

in order to find a good place for the food waste with an annual output of more than tens of millions of tons, China has started the pilot work of resource utilization and harmless treatment of urban food waste nearly 10 years ago. However, due to the poor front-end waste classification at that time, food waste, which has gone through three important links of collection, transportation and disposal from generation to final disposal, has been mixed with domestic waste for disposal. The slow progress of the pilot project is largely due to the high cost of the food waste treatment industry at one time, while the treatment subsidy price is flat, resulting in difficult operation of enterprises

taking Beijing as an example, the current recycling prices for food waste producers are 100/ton respectively, while the average cost of back-end treatment of food waste has reached 330/ton. This has also led to the fact that the number of existing food waste treatment projects is far from meeting the actual demand. At present, food waste treatment is just starting in a few cities such as Shanghai. Fortunately, since 2019, the waste classification policy has continued to exceed expectations, promoting the return of catering waste and kitchen waste to a pollution-free and low noise return channel. The total amount of wet waste separation in Shanghai alone reached 9200 tons/day, 1.45 times and 2.58 times that in 2018 and 2017 respectively

up to now, the food waste mainly consists of raw materials. Compared with the food waste, the salt content and oil content are lower, and the TS (total solid) content is generally about 25%. Generally, food waste treatment technology includes anaerobic fermentation, aerobic composting, feed technology, microbial treatment technology, etc. In view of the characteristics of high organic matter content and high moisture content of food waste, anaerobic digestion technology, which has the advantages of high economic benefits and small land use, has become the mainstream process route for the treatment of food waste at this stage, and is expected to be further promoted in the future

the capacity utilization rate has been appropriately improved, which has also driven the city scene of food waste treatment. "In the next 10 years, waste classification will add more than 400billion market opportunities." Zhangyizeng, member of the science and Technology Committee of the Ministry of housing and urban rural development, said. In addition, according to incomplete statistics, the investment in new food waste treatment projects in the past year reached 5.924 billion, a year-on-year increase of nearly 20.35%. In the first quarter of 2020 alone, dozens of new food waste treatment projects have been added, accounting for 59.38% of the new amount in 2019

according to the "13th five year plan" for the construction of harmless treatment facilities for urban domestic waste in China with the global new energy vehicle boom, by the end of 2020, 30% of urban food waste will be treated and recycled after classified collection and transportation. The corresponding total investment is 18.35 billion yuan, with an annual investment of nearly 4billion yuan. Assuming that the rhythm of releasing orders every year is evenly distributed, the food waste removal and transportation volume in 46 key cities will reach 130000 tons/day by 2020. Among them, the total investment and construction space for food waste (including kitchen waste) is about 49.8 billion, and the new investment space accounts for half of the total. The kitchen treatment market in the first tier cities and provincial capitals is gradually saturated, and it is constructed in strict accordance with the requirements of Shandong University and the standards of the State Key Laboratory; 12 enterprises have established cooperative relations with Shandong South University, and the number of new projects has been transferred to central and Northwest China

according to the calculation of the public team of Anxin environmental protection, the investment market scale of food waste treatment facilities during the "13th five year plan" period reached 100 billion. In the next five years, the daily treatment capacity of food waste will increase by 1.5-3 times, and the corresponding new investment space will further rise to about 92.6 billion. In terms of treatment and disposal projects and construction of treatment plants, if the investment per ton is 500000-1million, the market will be 50billion-100billion. In view of the weak profitability of a single kitchen waste treatment plant, some regions gradually promote the centralized disposal of waste or organic waste in venous industrial parks
