Project Overview
This project is a high-efficiency construction waste recycling plant designed for processing urban solid waste, renovation debris, and mixed commercial C&D waste in London, UK. To comply with stringent regional landfill diversion mandates and maximize material resource recovery, the client implemented a fully automated sorting and crushing line. The complete system integrates heavy-duty jaw crushers, ballistic separators, flip-flow screens, and advanced windshifter technology to process highly complex mixed waste stream streams, focusing on achieving maximum purity for recycled aggregates and ensuring continuous, long-term operational stability without material clogging.

Communication & Project Background
The client in London was facing critical operational bottlenecks due to the highly mixed nature of local renovation and commercial solid waste. Traditional sorting lines failed to efficiently separate heavy aggregates from light combustibles (plastics, foam, wood debris), leading to severe material clogging in downstream screens and high landfill tax penalties for unsorted residues. The client required a robust, automated construction waste recycling plant capable of high-throughput multi-stage separation while ensuring maximum end-product purity.
Our Solution
Through intensive technical consultations, engineering experts from Xinzhongyi Eco analyzed the material components and capacity requirements. Instead of standard generic layouts, Xinzhongyi Eco proposed a custom-engineered technical solution tailored to the client’s site constraints and material characteristics:
- Primary Crushing Stage: Utilizing a heavy-duty jaw crusher with a maximized feeding size to reduce oversized concrete and brick rubble to optimal grain sizes.
- Multi-Stage Screening Matrix: Integrating a ballistic separator and a flip-flow screen in sequence to eliminate material clogging, separating materials cleanly by three dimensions (3D heavy fractions, 2D light fractions, and undersized fines).
- Advanced Air Classification: Deploying an integrated air separation system (foam and hanging air separators) utilizing pneumatic principles to extract 95%+ of light impurities, ensuring clean, high-purity recycled aggregates.
Production Line System Parameters
- Processing Capacity: 80–120 TPH (Tons Per Hour) / Approx. 2000 m³/Day
- Raw Material: Construction and demolition waste (C&D waste), renovation debris, municipal solid waste
- Core Equipment: Heavy-duty jaw crusher, ballistic separator (bounce screen), flip-flow screen, foam air separator, hanging air separator, magnetic separator
- Sorting Method: Automated mechanical sorting + multi-stage pneumatic separation + ferrous metal extraction
- Separation Process: Heavy Crushing → Multi-Stage Screening (3D/2D Separation) → Magnetic Separation → Dual Air Separation → High-Purity Recycling
- Dust Control System: Fully enclosed workshop operation + heavy-duty dust encapsulation + negative pressure air filtration
- Plant Layout: Heavy-duty integrated steel structure configuration with compact multi-level spatial footprint
- Operation Mode: Continuous automated heavy-duty operation managed via a centralized PLC control system

System Advantages
Installation & Service Support
During project delivery, Xinzhongyi Eco engineers provided international on-site installation guidance and comprehensive commissioning support. We stayed on-site during key stages such as equipment alignment, structural integration, electrical connection, and trial operation, ensuring a smooth and safe startup of the entire processing system. Operator training was also provided to help the local technical team quickly master daily operation, screening parameter adjustment, and preventive maintenance.
Project Result
After the production line was put into operation, the construction waste sorting center maintained stable processing capacity under continuous daily operation. The automated mechanical sorting matrix significantly improved overall separation efficiency and minimized the need for hazardous manual picking in the primary processing section.
Compared with traditional sorting methods, recyclable materials such as metals, industrial plastics, and high-purity aggregates can be separated with extreme precision, helping maximize the commercial value of municipal solid waste. The stable operation of the combined ballistic separator and flip-flow screen has also completely eliminated material blockage and downtime during peak feeding periods, processing over 300,000 tons of solid waste annually.
Since commissioning, the production line has continued running steadily and has become an important landmark project for the customer’s long-term environmental sustainability and regional resource recovery strategy.
Project Feedback
“Xin Zhongyi Eco’s customized production line has not only completely resolved our long-standing waste disposal bottlenecks but has also delivered substantial economic returns. The market demand for high-purity recycled aggregates is exceptionally strong right now. Instead of worrying about heavy landfill liabilities and disposal costs, we are now generating a highly profitable revenue stream by selling premium sub-base materials back into the construction sector. It has truly turned our waste liabilities into a highly lucrative dual-benefit commercial operation.”
