Perfect garbage classification will greatly reduce the workload of sanitation workers. Japan, an example of garbage classification, has only 2,000 road sweepers in Tokyo. In this sense, the future of garbage classification means the end of traditional sanitation. Therefore, garbage classification is the top priority for environmental sanitation people who have to think, pay attention, and have to intervene.

The traditional sanitation mentioned here refers to the old sanitation relying on the head of the people, not the new sanitation that keeps pace with the times. The new environmental sanitation includes the continuous improvement of mechanized operations, the increasingly perfection of intelligent environmental sanitation, the wide application of environmental sanitation robots, and the general recognition of the value of environmental sanitation, of course, including garbage classification.

The current mainstream modes of garbage classification include four categories: "smart garbage classification, rural garbage classification + integration of the two networks, Internet + domestic garbage classification, sanitation and garbage classification coordination". (1) Smart garbage classification: use intelligent classification of garbage bins and points to effectively combine garbage classification and data collection; (2) rural garbage classification + integration of the two networks: integrate the two networks into rural areas, taking into account the amount of garbage reduction and Utilization of recycled materials; (3) Internet + domestic garbage classification: front-end dry garbage is packaged as a whole, self-delivered or door-to-door recycling, self-built garbage classification logistics and sorting system; (4) Sanitation and garbage classification collaboration: cleaning and cleaning, garbage collection and transfer Collaborate with classification.

The above four categories of operation modes are operated and implemented by the following seven major schools of garbage classification.

1. Department of Environmental Sanitation

Traditional environmental sanitation companies cut into the waste classification, taking advantage of the inherent advantages of the near-water tower platform, and some traditional environmental sanitation companies have entered the field of waste classification, such as Beijing Environment, Enlighten Sand, Yinqiao Environmental Protection, Xifu Environmental Protection, Hengsheng Tianjie, Pop Environment Hamawa environment etc.

2. Department of Recycling

As a pioneer of garbage classification, such enterprises are born in the field of waste material recycling, and cut into the garbage classification from waste recycling, such as the derived group "Little Yellow Dog", stupid brother technology "stupid brother", Jiulang Environmental "tiger brother", Tianlong Tiantian Jie "green cat", magic quadrant "Xiandou" and so on.

3. Department of IT

Most of these enterprises are from environmental sanitation-related IT technology, from providing waste separation IT technical services, to transforming to directly participate in the operation of waste classification projects, such as Zhiyun Zhihui, Murakami Environmental Protection, Yiqu Technology, etc.

4. Department of Biology

Most of these enterprises rely on their research and development and application of “combination of domestic waste resource treatment equipment and microbial treatment technology” to enter the field of waste classification, such as Baijiale Biological, Biaoge Environmental Protection, Lai Tai Bio, Dashu Biological Qingyuan Biology, etc.

5. Department of Supply and Marketing

Renewable resources are called the “last straw” of the supply and marketing people, and of course garbage classification is not to be missed. On April 12 this year, the All China Supply and Marketing Cooperative Association issued the “Guiding Opinions on Accelerating the Promotion and Transformation of the Renewable Resources Industry” 》 (Supply and Marketing Jingzi ﹝ 2018 ﹞ No.11), more and more such enterprises will participate in the garbage classification in the future. Representative enterprises include Zhejiang Renewable Resources Group and Suzhou Renewable Resources Investment and Development Co., Ltd.

6. Department of NGO

From the perspective of bidding projects, NGO departments have played an important role in the waste sorting work of certain cities, such as Shanghai Aiyi Youth Public Welfare Service ˙Shanghai Feilin Charity Development Center ˙Shanghai Minhang District Furui Charity Service Center ˙ Enjiu Charity Development Service Center of Shanghai Pudong New District ˙ Shanghai Aifen Environmental Protection Technology Consulting Service Center, etc.

7. Grass root system

The so-called grassroots refers to the civilian background of these enterprises, and their dedicated attitude towards garbage classification. Such as Nanjing Zhida, Chengdu Green Earth, and Chengdu Aubei Environmental Protection, which was born out of Green Earth.
