The mountain city is painted with lush greenery. Recently, the highly anticipated latest construction and decoration waste sorting project in Qinglv Environment has officially landed and successfully operated in Chongqing! This is not only another milestone established by Qinglv Environment in the field of solid waste treatment, but also a firm practice of Qinglv's technological innovation to help Chongqing build a "waste free city" and promote regional green and sustainable development.

The "New Exam Question" under the Urban Renewal of Garbage Resource Utilization

With the acceleration of urbanization and the improvement of people's quality of life, construction and decoration activities are becoming increasingly frequent, and the resulting construction and decoration waste has become a major challenge for urban management. This type of garbage has a large volume, complex composition, and high processing difficulty. The traditional extensive treatment method not only occupies a large amount of land resources, but also easily causes environmental pollution. How to achieve the reduction, resource utilization, and harmless treatment of construction and decoration waste has become a key link in promoting urban green transformation and building a beautiful China.

Chongqing, as the economic center of the upper reaches of the Yangtze River and an important national central city, has a remarkable speed of urban construction and renewal iteration. In this context, efficient, intelligent, and environmentally friendly solutions for building decoration waste disposal are particularly urgent. With years of technological accumulation and innovative practice in the field of solid waste treatment, Qinglv Environment has brought a new "green answer" to Shancheng.

Technology empowers a new paradigm of refined sorting

The construction and decoration waste sorting project that landed in Chongqing this time covers a total area of 20000 square meters, with a daily processing capacity of up to 600 tons. The sorting system is an efficient, intelligent, and environmentally friendly system solution carefully designed by Qinglv Environment for the complex composition and difficult sorting of project waste.

The incoming materials enter the 3D sorting machine through a uniform feeding machine, and are accurately and quickly sorted into three types of materials: 3D materials, 2D light materials, and screened materials. 3D materials mainly include bricks, tiles, stones, metals, wood, hard plastics, etc. Among them, magnetic metals such as iron will be adsorbed and screened by magnetic separators, and can be directly sold to metal processing factories.

Wood and hard plastics will be identified, located, and sorted through the "machine vision" technology of AI intelligent sorting robots. The robot integrates vision, AI algorithms, and serial high-speed motion control technology, with a sorting accuracy of over 95%.

2D lightweight materials mainly include woven bags, films, and clothing, with less ash content and higher purity. They are compressed and packaged into SRF and RDF, which can generate high profits in the back-end recycling market.

The screened material is separated into fine sand and small stones by a relaxation sieve, which is clean and has few impurities. It can be recycled at a high price to produce recycled building aggregates, water stable materials, cement fillers, etc

The entire line system of this project adopts a modular design with wider applicability and flexible customization. Through refined and intelligent sorting, higher sorting purity is achieved with fewer equipment and lower energy consumption, reducing operating costs while maximizing resource recovery benefits, achieving 100% resource utilization.

The Green Environment project not only achieved breakthroughs in core technology, but also demonstrated a high pursuit of quality and environment in many details.

Dust prevention and protection of green sorting throughout the entire line: In order to effectively suppress the dust that may be generated during the sorting process, Qinglv has equipped customized dust prevention modules (including sealed covers and drop trays) on all conveying equipment, reducing dust emissions from the source and ensuring the cleanliness of the on-site working environment and the health of workers.

Multiple dust suppression measures to create a fresh environment: Based on the actual site conditions, the project has installed an efficient negative pressure dust removal spray system above the factory area. The system collaborates with the dust prevention module to form a three-dimensional dust control system, ensuring the air quality of the entire factory area.

Intelligent robots for precise and efficient sorting: In addition to AI vision sorting machines, heavy-duty robots have been deployed on heavy material sorting platforms, which can automatically and accurately select specific materials according to preset programs, ensuring continuous stability and efficiency of sorting.

Craftsmanship in design, showcasing industrial aesthetics: Qinglv deeply understands that modern factories not only need to be efficient, but also aesthetically pleasing. The project team has also put a lot of effort into the exterior design of the sorting line system, striving to achieve a grand and clean appearance, showcasing the design sense of modern industrial equipment, enhancing the overall image of the factory area, and demonstrating the professional and industrial aesthetic concept of green environment.

The successful operation of the Chongqing project is another important achievement of Qinglv Environment's "low-cost, high availability, and sustainable" smart sorting solution. The project not only provides an efficient, intelligent and environmentally friendly demonstration model for building decoration waste disposal, but also verifies the reliability and progressiveness of the green system solution in complex application scenarios.

In the future, Qinglv will continue to deepen its technological research and application innovation, continuously optimize solutions, promote the upgrading of construction waste resource utilization from "mid-range sorting" to "full chain control", and provide professional construction waste resource utilization services for more cities.

We firmly believe that through technological empowerment, construction and decoration waste, which was once seen as a burden, will be transformed into valuable resources to promote urban green development and circular economy
