Building garbage "green regeneration", Kunshan City investment helps to build a "non -waste city"

On the occasion of the implementation of the "Regulations on the Management of Domestic Waste Classification of Suzhou City", a few days ago, the Suzhou People's Congress Standing Committee's Domestic waste classification law enforcement inspection team went to Kunshan Construction waste resource -based utilization center inspection project to operate the project. Inspection of the effectiveness of garbage classification, improve the actual effect of garbage classification and the sense of the people.

This year, Suzhou was selected as the construction list of "non -waste cities" during the "Fourteenth Five -Year Plan" period. As an important part of the construction of "non -waste cities", Kunshan City Investment Group closes carbon peaks, carbon neutral and major strategies, and strengthens "green low green low. Carbon development industry leadership, the construction industry leading construction waste resource utilization project, helping to build a county demonstration of modern urban construction.

Kunshan Building Waste Resource Resources is located at No. 28 Xingke Road, Yushan Town, with a total land area of ​​95,100 square meters and a total construction area of ​​54,500 square meters. In April 2022, it was put into production throughout the board. Product R & D and intelligent operations in environmental protection industrial parks.

Featured Mission: Create a special mission center for construction waste

When you enter the factory area, you can see the self -produced stone pavement tiles, imitation stone transmitted bricks, grass planting bricks, high -strength chain blocks, ecological gear walls, water transmitted concrete and other regenerative products, as well as green buildings, sponge cities and other technologies. On -site reality teaching bases for construction waste resources.

The factory area also builds a modern characteristic theme mission center. In various display forms, it shows the policy leadership, green factories, resource regeneration and smart management of construction waste resources, and depicts the specific practice of organic renewal of the city. The policy leader sector introduces the relevant green development concepts of my country, shows the construction results of Kunshan's practice of green development and layout of green environmental protection industries. The green factory sector mainly introduces the functional attributes of the project, showing the entire process of "turning waste into treasure" of each production line. The resource regeneration sector has different partitions, which mainly shows the regeneration products and application tests of construction waste. The smart management sector is the construction of the construction waste information management platform in Kunshan, and realizes the full control of the waste from the source to the terminal disposal.

Green Production: Build a national demonstration terminal disposal base

The project's existing 5 production lines such as the existing decoration garbage treatment line, demolition and construction waste treatment line, large garbage treatment line, green waste treatment line, and regenerative brick line are currently the largest scale in Suzhou City. project. Each production line introduces advanced technology and equipment at home and abroad, with an annual processing volume of more than 1.4 million tons, a harmless disposal rate of 100%, and a resource -based utilization rate of more than 95%.

The annual processing capacity of the decoration garbage treatment line is 300,000 tons, and the complicated decoration garbage has four categories: inorganic non -metallic materials, lightweight organic materials, other recyclables and hazardous waste. The rate is more than 99%.

The annual processing capacity of the demolition and construction waste treatment line is 1.1 million tons. The removal of waste concrete, waste brick tiles, etc., through technical processing such as splitting, peeling, crushing, plastic surgery, and restoration Natural Ingredients.

The annual production capacity of the regenerative brick line is 500,000 square meters. With regenerative aggregate as the main raw material, it is equipped with ingredients, stirring, molding, maintenance, packaging and other processes. Corrosive zinc, aluminum -magnesium alloy steel structure maintenance kiln, energy -saving constant temperature constant humidity maintenance system, etc., can produce various high -quality PC bricks. The annual processing capacity of the garden green waste treatment line is 30,000 tons. After sorting the green garbage is sorted, the branches are grinded by hammer, sieve, dyeing, and harmless treatment. The regeneration is the organic coverage to return to the garden greening. After the grass and leaves are crushed, it is used as an organic fertilizer raw material or biomass fuel to achieve 100%resource utilization. The annual processing capacity of large garbage treatment line is 15,000 tons. Disassembling and utilization of large -sized furniture such as sofas and mattresses is a simple and efficient comprehensive use treatment method.

Product R & D: Explore the industry's leading regeneration technology research and development

Kunshan Urban Investment Group has conducted in -depth research and development of product research and development, released the first province's technical standards for enterprise enterprises, and participated in the preparation of 2 national standards, group standards and technical regulations. Cooperate with the major institutes such as Southeast University and Nanjing University of Technology to explore the construction of industry -university -research platforms, promote the construction of laboratory, and promote related technologies and applications at the forefront of the country.

At present, regeneration products have been successfully applied to the city's western medical center, opera hundred opera museums, Xiao Taoyuan, Zhangjiagang river channel, airport road, Tongfeng Road and other projects to achieve green regeneration of construction waste. Compared with traditional materials, about 30%of the cost of materials can be saved.

Smart operation: Constructing the country's first global collection and transportation system

In recent years, Kunshan Urban Investment Group has actively united the industry authorities to coordinate planning and scientific layout, plan construction waste disposal facilities in the city, and promote Kunshan's construction waste "one nuclear and two wings, multi -link linkage" city and village coverage system coverage system coverage system coverage system Implementation. Use the Internet of Things technology to develop the intelligent collection cloud platform, realize the "one -click clearing" of construction waste, open the last mile, and truly achieve the construction of construction waste in each district and towns.

"One nuclear" refers to a city -level disposal center, namely Kunshan construction waste resource resource utilization center,

The project is the first comprehensive resource utilization project that integrates the construction of garbage, decoration garbage, large garbage, and garden green garbage in Kunshan City. The disposal services are facing the city.

"Two wings" refers to the two disposal centers, namely the split center of the flower bridge disposal and the southern disposal center.Huaqiao disposal center disposal service covers the Huaqiao Economic Development Zone, Lujia Town, and Qianhuang Town; the disposal of the disposal center of the southern disposal center covers Zhangpu Town, Dianshan Lake Town, Zhouzhuang Town, and Jinxi Town.

"Multi -point linkage" refers to the collection and transportation system facilities.Including construction waste transfer points and mobile collecting boxes.

The transit point is an important supporting facility for the collection of garbage, large garbage, and garden green waste in various areas of the city, and uses information management.At present, the transit point of Tinglin and Baolu area has been completed.There are more than 130 communities in the middle rings in the mobile collecting box, and residents in the community can put in decoration garbage.The collection box is equipped with GPS positioning and automatic capacity monitoring.

In the next step, Kunshan Urban Investment Group will be based on a new journey of socialist modernization, closely follow the county demonstration requirements of modern cities, comprehensively implement the "non -waste city" construction and deployment, practice new paths for green and low -carbon development, promote the efficient intensive production space intensive efficiency, A moderate living space and a beautiful ecological space.
