In today’s rapidly urbanizing world, construction and demolition waste (C&D waste) has become one of the largest and most challenging waste streams. Traditional methods like landfilling and low-efficiency manual sorting are no longer viable—economically or environmentally.
At Qinglv, we engineer intelligent waste sorting systems designed specifically for construction waste and demolition waste. By integrating AI garbage sorting, advanced screening machines, and automated material recovery technology, we help turn waste into valuable resources—boosting waste recycling rates and enabling true circular economy solutions.
What Is Construction & Demolition Waste?
Construction and demolition waste includes materials such as concrete, bricks, wood, metals, plastics, insulation, and mixed debris generated during building, renovation, or demolition activities. Without proper waste management, these materials often end up in landfills, losing potential value and increasing environmental footprints.
An effective C&D waste recycling system begins with accurate identification and separation—which is where smart sorting technology comes in.
C&D Waste Trends
Globally, C&D waste volumes are rising steeply due to increased urbanization, infrastructure upgrades, and renovation projects. In many regions, regulations are tightening, pushing for higher recycling rates and discouraging landfilling. Investing in efficient waste screening equipment and waste recycling equipment is no longer optional—it’s a strategic necessity for sustainable growth.
How C&D Waste Is Screened And Recovered
The waste sorting process begins with the Bag Breaker, which opens and loosens incoming construction waste. The material then moves to the Trommel Screen, where fine stone powder and small pebbles are screened out. Next, the 3D Sorter separates the remaining waste into three streams:
3D materials (such as metals) are sent to the Magnetic Separator for ferrous metal recovery, while an AI Sorting Robot picks out wood and plastic, leaving clean bricks and stones.
2D materials (like paper, cardboard, and film) are compressed and sold as recyclables.
Undersized material is collected as aggregate for reuse in construction applications.
This integrated system ensures efficient separation and high-value recovery from construction waste streams.
The Challenges Of Screening C&D Waste
Screening construction and demolition waste is difficult due to:
1.Highly mixed and contaminated material streams
2.Variable sizes and weights
3.Abrasive materials that wear down equipment
4.Need for high throughput and consistent output quality
5.Many conventional screening machines struggle with blockages, low accuracy, and high maintenance costs.
That’s why Qinglv designs robustness and intelligence into every component—from our Disc Screen with special anti-clogging disks to our AI Sorting Robot that adapts to changing waste compositions in real time.
Quality of Recovered C&D Material
The economic value of recycled materials depends directly on their purity. Qinglv’s system ensures:
Clean aggregates free from wood, plastics, and metals
High-purity metal fractions recovered via Eddy Current Separator and Magnetic Separator
Sorted plastics and papers ready for recycling markets
Uniform RDF pellets from our RDF Pellet Machine
With our technology, recovered C&D material meets industry standards for reuse in construction, manufacturing, and energy recovery.

Real-World Projects: Guangdong & Shanghai C&D Waste Recycling Plants
1. Guangdong Decoration & Renovation Waste Recycling Project
With a site area of 10,000 m² and an annual processing capacity of 600,000 m³, this project achieves 100% resource recovery from renovation waste. As the first in China to deploy AI waste sorting robots for construction and demolition waste, it reduces investment costs by about 40% compared to the industry average, shortens the payback period by 30%, and increases resource revenue by 15%, fully demonstrating the significant advantages of intelligent sorting in enhancing both economic returns and processing efficiency.
2. Shanghai Construction & Renovation Waste Resourceization Project
Covering an area of 6,000 m² and designed to process 300,000 m³ of waste annually, this project reduces investment costs by approximately 40% and shortens the return on investment period by 30% compared to industry averages. Through efficient sorting and recovery processes, it also delivers a 15% higher profit from recovered materials, reflecting stable and notable economic and environmental benefits.
Conclusion: Smarter Sorting for a Circular Future
The shift from linear disposal to circular recovery is accelerating. With Qinglv’s smart waste sorting systems, contractors, recyclers, and municipalities can turn C&D waste from a cost burden into a revenue stream—all while meeting sustainability targets.
