Changchun builds a city with the characteristics of "no waste cells"

Changchun, Jilin, is lined with green trees, and summer is full of heat and passion.

The "Waste-Free City" project of Changchun Circular Economy Industrial Park located in Mishazi Town, Dehui is under vigorous construction. "The central area on the east side of the park is the green intelligent sorting center in the first opening area of the first phase of the project. We will realize the supply of recycled raw materials through this center." Dong Hui, the project leader, told reporters that this project with a total investment of 12.5 billion yuan will strive to create a waste material recycling system featuring recycling and industry-city coordination.

Since it was selected into the national "waste-free city" construction list during the "14th Five-Year Plan" period in April 2022, Changchun City has insisted on taking "waste-free city" as a concrete practice of the green development concept, practicing the waste-free concept in multiple ways, and providing the city with "waste-free cell" construction units and the general public issued an initiative to guide the founding units on site to actively carry out cell construction such as "waste-free factories","waste-free hospitals" and "waste-free schools". The construction of "waste-free cities" has taken root in all walks of life in Changchun City. Blossoms and fruits.

"Small cells" from point to surface play a big role

Walking into the "waste-free school", you can feel the low-carbon and environmentally friendly atmosphere everywhere, the promotion and practice of domestic waste classification, biodiversity education parks, turning waste into treasure and other environmental innovation activities...

At Anmin Primary School in Chaoyang District, Changchun City, scenes of interaction between the concept of "no waste" and children can be seen everywhere.

"Last year, the garbage after sorting was sold to buy rapeseed seeds. The students planted it, and the small vegetables grew very high. This year, the children are working hard to classify the garbage." Wang Jinhua, principal of Anmin Primary School, introduced that the school organized students to hold garbage classification competitions, green recycling theme class meetings, hand-painted publicity exhibitions, handmade works exhibitions and other activities to uphold the principle of saving paper, saving supplies, saving water, saving electricity, and saving meals. The "five savings" concept not only reduces the generation of garbage from the source, but also subtly roots the concept of green recycling in the hearts of students.

"Create an ecological educational environment where mutual growth and mutual growth, awaken children's desire to be close to nature, and integrate the concept of 'no waste' into every corner of the school." Wang Jinhua introduced.

Anmin Primary School is a leader in the province's "waste cell-free" construction. It integrates green development concepts into all aspects of education and teaching, promotes the realization of "visible, reducible, usable, and consumable" waste on campus, and ultimately achieves "reduced waste generation, fully utilized resources, and safely disposed of" the entire campus.

Driven by typical examples, as of June 2024, a total of 435 "waste-free cells" have been built in Changchun City, including 45 "waste-free schools", forming an innovation pattern in which typical experiences promote each other, making the construction of "waste-free cities" in Changchun City further extensive, life-oriented and concrete.

"In the process of building a 'waste-free city', our province has given full play to the' leading goose 'role driven by the' waste-free cells'demonstration, and maintained a good situation in building a 'waste-free city' from less to more, from point to point., let the leading role of typical examples be continuously strengthened." Xu Bing, the ecological environment inspector of the Provincial Department of Ecology and Environment, told reporters that as of now, 824 "waste cell-free" of various types have been built in the province, and plans to select 20 models from mature "waste cell-free" units to be built to conduct in-depth summary and promote experience throughout the province to further play a leading role in demonstration.

Large projects "come true" to promote the "big circulation" of waste materials

Effectively place the construction of "waste-free cities" in all relevant fields across the province with "visible and tangible" projects.

"Changchun Circular Economy Industrial Park will establish an Alibaba Cloud AI Intelligent Computing Center, introduce upstream and downstream enterprises for recycling and remanufacturing waste materials, and connect enterprises in the park through big data platforms to achieve business linkage and information sharing among enterprises and achieve economic benefits." Dong Hui told reporters that at present, Changchun Circular Economy Industrial Park is working with the Provincial Department of Ecology and Environment to build a Jilin Province Carbon Inclusive Platform to build the park into the first carbon certification and carbon trading circular economy demonstration industrial park in China, diversifying carbon trading categories.

The project construction requires financial support. In order to "attract living water" and provide more sufficient financial security, the Provincial Department of Ecology and Environment coordinated 12 financial institutions and compiled a "Financial Support Manual" to create a "Jilin Financial Supermarket" for "waste-free city construction". Explore the effective complementarity and organic linkage between government assistance and market role to break through the difficulties and blockages of "difficult financing" and "expensive financing".

After active planning and solid implementation, 261 projects with a total investment of 88.42 billion yuan in the province have been successfully included in the "waste-free city" reserve. Currently, 197 projects have been started and 141 have been completed.

On this basis, Changchun City Circular Economy Industrial Park came into being. The industrial park plans to build an entire industrial chain that integrates the utilization of 12 renewable resources such as scrapped automobiles, scrap steel, waste paper, waste plastics, waste nonferrous metals, waste tires, waste power batteries, and waste electrical appliances. After all three phases of the project are completed and put into operation, the industrial park can realize closed-loop management of the information industry chain of waste materials in Changchun through the big data platform, including collection, transfer, deep processing, recycling, and trading, and recycle of waste materials. The carbon footprint of the product is traced throughout, and the carbon emission data of waste materials in different links of collection, transportation and deep processing are accurately calculated. After the park is put into operation, a circular industry cluster will be formed.

The construction of industrial parks not only promotes the "big circulation" of waste materials in Changchun City, but also spreads "tentacles" throughout Changchun urban areas to promote the implementation of the "waste-free concept." Wang Zhanlong, deputy director of the Changchun City Ecological Environment Bureau, introduced that Changchun City Circular Economy Industrial Park plans to establish nearly a thousand convenient recycling stations and transfer stations in Changchun City, and establish green intelligent sorting centers in counties and cities to continuously standardize the recycling status from "dirty and messy" to "neat and uniform", promote the centralized treatment of waste materials around citizens, ensure the supply of raw materials in Changchun Circular Economy Industrial Park, and at the same time promote the waste-free concept to better penetrate into the streets and alleys. Integrate into daily life.

Technological research accelerates the construction of waste-free cities

The key to green development transformation lies in technological innovation. As a well-known "automobile city" in the country, how to effectively combine the construction of a "waste-free city" with the production of the automobile industry has become a top priority for Changchun City. FAW Group Hongqi Manufacturing Center strives to solve the problem, focusing on solid waste reduction, and actively exploring and constantly trying from the direction of scientific and technological innovation.

"I vote for" Phosphating Slag Drying Project "! This project can effectively reduce the moisture content of phosphating slag to 30% to 40%!" In the conference room of Hongqi Manufacturing Center, the atmosphere of the first annual excellent environmental protection case selection activity was lively. Employees attending the meeting voted for good projects to reduce pollution and carbon. Nine excellent cases stood out in the selection, and the selected projects will be implemented simultaneously in each factory area.

It is reported that Hongqi Manufacturing Center has focused on technical difficulties to build a "waste-free factory" and has set up 34 key research topics. It has joined forces with FAW Group's R & D Engineering Technology Department, Safety and Environmental Security Department and other departments, and under the guidance and technical assistance of the Changchun City Ecological Environment Bureau, we will jointly promote process optimization measures such as returning packaging materials to the factory, reducing the number of coating screening points, and one-stop spraying of coating, effectively transforming scientific and technological achievements and promoting the construction of "waste-free factories."

With the continuous efforts of the joint research team, the Hongqi Manufacturing Center has implemented 22 energy-saving and carbon-reduction measures, including equipment efficiency improvement, management improvement, digital intelligence application and clean power application, which have effectively reduced carbon emissions by 15% every year and generated hazardous waste from bicycles. The decrease is 22.7% and will continue to decrease.

Build platforms, strengthen policies, implement projects, and gather resources... In terms of creating a "waste-free city", Changchun has initially formed a "Changchun" comprehensive management of "reduction, resource utilization, harmlessness, and low-carbon" solid waste."Model", realizing the leap from "construction" to "completion".
