Integration of the two networks-the mode and path of domestic waste reduction and recycling [4]
Third, how to implement the "two networks integration"
1. Difficulties and emphases of domestic waste
Identify the difficulties. The layout of domestic waste industrial chain, front-end source classification and back-end processing and utilization (especially low-value recyclables processing and utilization) are two major difficulties. The source classification is not in place, which makes it difficult for back-end processing and utilization; The back-end processing and utilization chain is missing, and the front-end classification is difficult to sustain. To implement the integration of the two networks, we must first study these two difficulties.
Lock the key points. Kitchen waste and recyclable waste, especially low-value recyclable waste, are the focus of reduction. By promoting the "integration of the two networks", the recovery amount of recyclable garbage and the resource utilization amount of kitchen waste will be improved, the garbage removal amount will be reduced to the greatest extent, and the terminal processing pressure will be reduced.
2. Promote the four principles of "two networks integration"
Principle of overall planning and coordination. Strengthen the coordination of various departments, establish a joint promotion mechanism, clarify the responsibilities of all parties in industry supervision, territorial management and subject implementation, and strengthen resource sharing and overall cooperation in network layout planning, facilities and equipment sharing, sorting and recycling service cooperation, incentive mechanism and publicity activities.
Principle of adapting measures to local conditions. According to the actual situation of resource recovery and garbage removal system, each region should choose the integration mode and operation mode suitable for the local area, try it first, and then gradually promote it in an all-round way after gaining mature experience, so it is forbidden to apply it across the board.
Policy support and market drive. Low-value garbage is driven by policy, while high-value garbage is driven by market. It is necessary to establish a policy support and guarantee system for low-value recyclables and kitchen waste, so as to incite market forces and form a long-term operation mechanism for low-value waste.
The principle of policy promotion, market operation and national participation. The government plays a driving and guiding role in industry planning, administrative measures, and policy mechanism guarantee. Enterprises operate industrially according to government planning. Garbage is a social public problem, and the whole people participate in garbage classification.
3, "two networks integration" to achieve three purposes.
Through the integrated operation of resource recovery network and garbage removal network in each link, we can achieve the following goals: First, reduce and recycle domestic garbage, reduce the pressure of domestic garbage terminal treatment, and promote the recycling of resources. Second, by integrating the human resources and facilities of the two major networks of sanitation, cleaning and resource recovery, collecting scavengers, improving resource recovery outlets and processing centers, a perfect and standardized recycling system for renewable resources will be formed. Third, through the integration of the two networks, promote the transformation and upgrading of renewable resources enterprises to environmental services.
4, the government, enterprises and the public rights and responsibilities.
The government is the management subject of domestic waste classification and reduction, and its responsibility is to legislate, plan, promote and supervise; Enterprises are the main operators of domestic waste, undertaking the classification, recovery, removal and treatment of domestic waste, and establishing the whole industry chain of domestic waste; Residents (including various units that produce garbage) are the producers of domestic garbage, and they are the responsible subjects of classified delivery of domestic garbage. Their duties are to classify delivery and supervise the behavior of the government and enterprises according to relevant government requirements.
5, garbage classification management responsibility subject
(1) Improve the three-level management structure. Improve the three-level organization and management structure of city, district and street (community), and pay attention to legislation, planning, overall coordination and establish a policy support system at the municipal level; At the district level, according to the planning and overall planning of the municipal government, we should do a good job in organizing, implementing and promoting, and be responsible for management; Street (township) to implement the main responsibility of management, responsible for the specific implementation of garbage sorting work to communities and households, mobilize the strength of all parties in the region, give full play to the role of neighborhood committees, communities and property enterprises, coordinate and organize the implementation, and promote the effective implementation of garbage sorting.
(2) Determine the responsible subject of garbage classification management. Garbage classification involves thousands of households, and all localities must clarify the main body of responsibility for garbage classification management: urban residential areas, where property management is implemented, streets and property service units are the main body of responsibility for classification management; Institutions, enterprises and institutions, the unit is the subject of classified management responsibility; All kinds of public places, business management units are responsible for classified management.
(3) The responsibility of the subject responsible for garbage classification management. Its responsibilities include: establishing a daily management system for domestic waste classification, and announcing the time, place and way of putting different types of domestic waste; Carry out classified publicity of domestic waste, guide and supervise units and individuals to do a good job in source reduction and classified delivery of garbage, and advise and stop acts that do not meet the requirements of classified delivery until they are mandatory; According to the relevant regulations, combined with the domestic waste output and delivery mode, the domestic waste classified collection containers are reasonably set up and kept clean and beautiful.
6, "two networks integration" operation subject
(1) cultivate the main body of operation. Through bidding or other means, select recycling enterprises with standardized management and honest operation in the renewable resources industry, or introduce enterprises from other industries as local operators to undertake the "integration of two networks", and connect the recycling and resource utilization of recyclable garbage, kitchen waste and harmful waste to build a resource recycling network and a garbage industry-wide chain.
(2) Adopt operation mode according to local conditions. After the actual investigation and summary by the expert group, what kind of operation mode is adopted by the operation subject can be adapted to local conditions according to local conditions and the conditions of the enterprise itself:
◆ Integrated mode of sanitation recovery. This model usually means that the government purchases services, and chooses an operator to undertake garbage sorting, sanitation and transportation, road cleaning, resource recycling and processing, and kitchen waste recycling, so as to provide the government with a package of domestic waste solutions, which is an all-round "two networks integration". Such as Zhuhai Xifu Company and Qidi Sander Company in Pingdu, Shandong Province.
◆ Cross-border transformation mode of renewable resource enterprises. Traditional renewable resource enterprises undertake waste sorting, network layout, recycling and processing of recyclable waste and resource utilization of kitchen waste, so as to realize the cross-border transformation of traditional renewable resource enterprises to environmental services. For example, Guiyang Gaoyuan Company, Guangzhou Supply and Marketing Cooperative, and Beijing Tiantianjie model.
◆ The extension mode of sanitation enterprises to the back end. Environmental sanitation enterprises are involved in garbage sorting, recyclable garbage recovery and resource processing and utilization. Their advantages are to give full play to the resource advantages of environmental sanitation and cleaning manpower and facilities, and improve the synergy efficiency of the two networks. Such as Beijing Jinghuan Group and Hangzhou Environmental Sanitation Group.
◆ Comprehensive government intervention mode. Government departments are fully involved in classification, station yard, network setting, main enterprise selection and layout of back-end processing and utilization, and local financial funds provide strong support. This model takes effect quickly and is suitable for initial pilot. Such as Yuexiu District in Guangzhou, Songjiang District in Shanghai and Suzhou Environmental Sanitation Department.
◆ Distributed processing mode. The front end realizes dry and wet classification, and the middle end uses the garbage compression room and transfer station of the sanitation system to carry out transformation and upgrading, and treats kitchen waste and recyclable garbage nearby and dispersedly, achieving "one field for two purposes" and changing centralized garbage treatment into distributed garbage treatment. Its advantages are short transportation distance, low logistics and site cost, and reduced leakage. Such as the practice of Shenzhen Yingchan Technology.
◆ Single-variety whole industrial chain model. Establish a single variety recycling network and a specialized processing and production base, and build a whole industrial chain of specialized recycling, processing, utilization and terminal product manufacturing. This model is suitable for low-value recyclables such as waste spinning, waste glass, and large pieces of garbage. Such as Guangdong Hengfeng Textile Co., Ltd..
