When the construction of "waste free city" is right, how does digitalization empower solid waste management

At present, China implements the whole process supervision of solid waste from source to end. Due to the variety of solid waste, complex production situation, involving a wide range, its supervision can not be limited to whether the end disposal is up to standard, but also from the production process of the product to sort out and check the production node, type, nature, quantity of waste, but also track the storage, transfer, utilization, disposal and other circulation processes of waste, to ensure the standardization of treatment and harmless disposal.

The environmental supervision conditions of solid waste are complex, coupled with the late start of environmental management of solid waste in China, the input of human, material and financial resources is limited, fortunately, information technology has been widely used, which is of great significance for optimizing resource allocation, improving operational efficiency and controlling environmental risks.

•                      Digital application of "no waste scenario"

During the pilot period of "waste free city" construction, all localities made full use of modern scientific and technological achievements such as big data, the Internet, and the Internet of Things, built information platforms, and coordinated functions such as enterprise information declaration, government environmental supervision, online waste trading, transformation of scientific and technological achievements, and public supervision.

Build a smart supervision platform for hazardous waste to achieve the whole process information management of "positioning, inquiry, tracking, early warning, and assessment". Through the application of intelligent weighing equipment, handheld intelligent terminals, electronic locks, positioning systems, cameras, two-dimensional code labels and other iot terminal equipment and technologies, the whole process of hazardous waste generation, collection, storage, transfer, utilization and disposal is implemented in real-time visual monitoring and information management. Through the integration and analysis of big data, the traceability system of the whole life cycle is formed, the integration of environmental supervision and analysis and decision-making is realized, and the management efficiency and level of hazardous waste are comprehensively improved.

Build a waste recycling trading platform to achieve accurate matching and online trading between solid waste producers and processors. The relevant information of the waste production unit, treatment unit, transport unit, as well as the detailed situation and treatment needs of the waste are integrated into the trading platform. All units connect supply and demand through the Internet, and after demand screening, service consultation, and qualification verification, online transactions and offline processing are carried out to achieve efficient connection of all links of solid waste. By connecting the database or information system under their management with the trading platform, various government functional departments can play an effective role in qualification certification, real-time supervision, credit evaluation, emergency response, etc.

We will build a high-end platform for scientific research and technology transformation, and promote the marketization and industrialization of solid waste pollution prevention technologies, products, processes, and equipment. Governments, enterprises, institutions of higher learning and research institutions make full use of the platform to promote the effective combination and precise investment of talents, information, capital and technology by setting research projects (special projects and funds), proposing industrial needs, disclosing project information, promoting the transformation of results, and establishing exchanges and cooperation, and strengthen the deep integration and collaborative innovation of industry, university and research. We will increase the speed and efficiency of transforming scientific research results.

Build a public service platform, enhance the participation of the public in building a "waste free city", and achieve joint construction and governance. Set up a waste free zone on the official website to share the construction experience of "waste free city" and encourage mutual learning and learning. Relying on emerging network platforms such as public accounts and we-media, we conduct publicity, education and social supervision, while accepting public supervision, and relying on the wisdom of the masses, timely adjust the implementation methods of policies to ensure the operability and landing of policies. Raise funds through multiple channels on the platform, encourage social capital to participate in the construction of "waste free city", and ensure the smooth development of various works.

•                               Treating waste with quantity             We will promote refined management of solid waste

The digitalization of solid waste management is the mainstream of solid waste management in the future, and the application of digitalization makes the solid waste disposal industry shift from "extensive" to "refined".

On the one hand, the digital application of "no waste scenario" can provide the industry enterprises with the most timely, accurate, comprehensive and authoritative industry information, data analysis, cutting-edge technology, etc., and effectively integrate the high-quality enterprise resources of the whole chain of solid waste, including waste enterprises, disposal enterprises, comprehensive utilization enterprises, transportation enterprises, quality inspection agencies, environmental assessment enterprises and other environmental protection enterprises. Through the integrated service platform, the information channel between various enterprises is opened, so that the production and waste enterprises and disposal enterprises can realize information interoperability, reduce transaction costs, and maximize the complementary advantages and resource sharing.

On the other hand, relying on a new generation of information technology, the whole process of solid waste disposal can be traced. In the whole process of solid waste disposal, relying on high-tech intelligent means to achieve real-time data acquisition and dynamic update, the use of three-dimensional monitoring, intelligent perception, accurate identification, rapid response and other technologies, to achieve the whole process from source generation, process transportation to treatment and disposal can be monitored, early warning, traceability, sharing, evaluation, and supervision. Finally, a complete closed-loop data chain with "source traceable, destination traceable, supervision and responsibility traceable" is formed.

The application of digitalization not only greatly improves the closed-loop disposal and supervision capacity of solid waste, but also provides a "new engine" for the large-scale development of the solid waste industry, continuously injects momentum into the construction of "waste free city", and draws a picture of high-quality ecological development.
