Quangong's Innovative Brick-Making Solutions Power the Rise of Zero-Waste Cities
Unlocking the Value of Circular Economy
Driving Sustainable Urban Development
China generates over 3.5 billion tons of construction waste every year, yet less than 30% of it is effectively recycled. At Quangong Machinery (QGM), we believe waste should be a resource—not a burden. Our Integrated Construction Waste Recycling Solution transforms this challenge into opportunity through a closed-loop system of crushing & screening, intelligent batching, and high-pressure forming, delivering true zero-landfill results. To date, we’ve empowered over 30 cities in their journey toward becoming zero-waste urban pioneers.
Technological Innovation at Its Core
Smart Material Sorting
Advanced Multi-Stage Screening: Utilizing eddy current separators and near-infrared sensors, we achieve ultra-precise separation of metal, plastic, and concrete particles—with a purity rate of up to 99.5%.
Aggregate Enhancement: Construction waste is transformed into premium 0–10mm graded aggregates through high-pressure grinding, boosting compressive strength by 40%.
AI-Powered Mix Design
Dynamic Formula Matching: Powered by AI, our system tailors cement ratios based on aggregate type—whether brick-concrete, pure concrete, or gypsum—supporting over 12 product types, from permeable pavers to curbstones.
Strength Amplification: With nano-silica activators, our products reach 45 MPa compressive strength in 28 days—15% stronger than those made with natural aggregates.
Eco-Friendly Manufacturing
Dust & Noise Control: Our fully enclosed workshops and advanced dry mist dust suppression systems keep emissions under strict limits—dust < 5 mg/m³, noise ≤ 70 dB.
Water Recycling System: Using reverse osmosis technology, we achieve 100% water reuse, saving over 100,000 tons of water annually.
