Since the 12th five-year plan, China's kitchen waste treatment has made great breakthroughs and progress. According to statistics, at present, there are 118 restaurant-kitchen-waste treatment plants under construction, built or under preparation, of which more than 40 have been put into production. The 118 treatment plants are expected to have a daily processing capacity of 20,000 to 30,000 tons after they are put into operation.

"It is estimated that by 2020, China will still have a shortage of 10,000 tons of daily kitchen waste disposal capacity, so it needs to improve the capacity. In addition, the national management measures need to be promulgated and implemented as soon as possible, and a long-term operational mechanism needs to be established to ensure the healthy and sustainable development of the restaurant-kitchen-waste treatment industry. Ren lianhai, dean of the department of environmental science and engineering at Beijing technology and business university, pointed out at the 2016 solid waste strategy BBS.

The industry is beginning to take shape

Governments at all levels promulgate relevant policies; The production of gutter oil has been curbed to some extent. Explore the successful technical route and development mode; A number of active enterprises have emerged

In order to make up for the serious shortage of restaurant-kitchen-waste treatment capacity, during the 12th five-year plan period, the national development and reform commission subsidized more than 2 billion yuan and approved five pilot cities nationwide, planning to build 100 restaurant-kitchen-waste treatment plants. At present, the first batch of 6 treatment plants have been accepted, it is reported that the second batch before the end of this year to carry out acceptance work.

"The pilot cities basically cover the country's first - and second-tier cities, as well as some third-tier cities. It should be said that the kitchen waste treatment industry has begun to take shape and made obvious progress in many aspects.

In terms of policy, in order to standardize and promote the development of kitchen waste treatment industry, in recent years, some relevant policies, especially local policies, have been issued. Up to now, nine provinces (municipalities directly under the central government) have issued provincial-level measures for management of kitchen waste, such as Beijing, Shanghai, shandong and jiangsu. 101 prefecture-level cities have introduced relevant administrative measures, as have some districts and counties.

At present, some kitchen waste treatment plants have begun to operate, to a certain extent to curb the trend of kitchen waste back to the table. To this, ren lianhai expresses, the original intention that develops industry of management of meal hutch rubbish, basically be to put an end to gutter oil and solve table food safety problem. "If the kitchen waste is controlled, the franchising enterprise will make it harmless and cut off the production channel of gutter oil. From that point, the results are clear."

In addition, through the engineering practice in recent years, also explored some successful technical route and development mode. According to him, Beijing technology and business university and the national development and reform commission, combined with practical experience, is writing a technical guide to the kitchen waste treatment industry.
