Shanghai Dongmeng Tracked Mobile Jaw Crusher Breaks Ground in C&D Waste Recycling

Global C&D Waste Crisis Demands On-Site Processing Solutions

Construction and demolition waste has become one of the most pressing environmental challenges of our time. Globally, C&D waste generation exceeds 35 billion tonnes annually, yet recovery rates remain critically low in most regions. In China alone, annual construction waste generation surpasses 3 billion tonnes——accounting for over 40% of total urban waste—while resource utilisation rates remain below 10% nationally. This widening gap between waste generation and processing capacity has created an urgent need for equipment that can process demolition debris directly at the source, converting what was once a disposal liability into valuable recycled aggregates.

Governments worldwide are responding with increasingly stringent regulations. China‘s State Council issued the Opinions on Further Strengthening Urban Construction Waste Management, mandating that by 2027, the average resource utilisation rate of construction waste in cities at prefecture level and above must reach 50% or higher. The Action Plan for Comprehensive Solid Waste Treatment further reinforces these requirements, with construction waste reduction, transportation, utilisation, and disposal costs now incorporated into project budgets. For quarry operators, contractors, and recycling companies, these policies signal a clear directive: on-site processing is no longer optional—it is a regulatory necessity. OCP Mechanical Company, as the export brand of Shanghai Dongmeng, brings over 40 years of manufacturing experience to the global C&D waste recycling market. Our tracked mobile crushing plants deliver the mobility, reliability, and environmental compliance that modern demolition projects demand.

The Dongmeng Solution: Tracked Mobile Jaw Crushing Stations for On-Site Processing

Shanghai Dongmeng‘s tracked mobile jaw crushing stations are engineered specifically for the challenges of construction and demolition waste processing. Unlike traditional fixed installations that require material to be hauled to a central facility, these tracked units can be deployed directly to demolition sites, processing concrete blocks, bricks, mortar, and mixed rubble where they are generated. The machines feature full hydraulic drive with strong off-road capability, enabling them to navigate rough terrain, narrow urban sites, and confined demolition zones without the need for poured concrete foundations or complex installation. This “crush on-site, screen on-site, recycle on-site” approach eliminates secondary transport pollution and significantly reduces project costs.

What sets Dongmeng’s tracked jaw crushers apart is their integration into a complete closed-loop processing system. Each unit is equipped with an automatic iron removal system that efficiently separates rebar, wire, and other ferrous contaminants from the crushed material, protecting downstream equipment and improving recycled aggregate purity. The system achieves iron recovery rates exceeding 90% , ensuring that valuable scrap metal is recovered while the cleaned aggregate meets specification. The process follows a “classification pre-treatment—crushing—screening—impurity separation” closed-loop workflow, delivering multiple grades of recycled aggregates—typically 0–5 mm, 5–10 mm, 10–20 mm, and 10–31.5 mm—suitable for brick manufacturing, road base, water-stable layers, and construction backfill.

Environmental Compliance: Enclosed Design with Dust and Noise Control

For urban demolition projects, environmental compliance is often the deciding factor in equipment selection. Dongmeng‘s tracked mobile crushing stations are equipped with spray dust suppression systems, fully enclosed conveyor belts, and noise reduction and vibration damping devices as standard. These features ensure that dust and noise emissions remain within the strict environmental standards applicable in key regions, avoiding costly work stoppages and regulatory penalties. The machines are designed for green operation, with all transfer points enclosed and dust suppression integrated into the process flow. This level of environmental control is particularly important for projects in densely populated urban areas, where community complaints and regulatory scrutiny can halt operations. Dongmeng’s equipment has been deployed across multiple urban renewal and demolition projects in China, demonstrating reliable performance under real-world compliance conditions.

Proven Field Performance: From Fuzhou to Chongqing

Shanghai Dongmeng‘s tracked mobile crushing solutions have been validated across diverse operating environments in China. In Fuzhou, Fujian Province, a 100 TPH construction waste recycling project has been operating successfully, converting demolition debris into specification-grade recycled aggregates. Additional production lines have been commissioned in Chongqing, Guangdong, and Sichuan, processing concrete, brick, and mixed construction waste with capacities ranging from 100 to 250 tonnes per hour. These installations have demonstrated the equipment’s ability to handle variable feed conditions, including reinforced concrete and mixed rubble, while maintaining consistent product quality and minimal downtime. For international operators, these field-proven results provide confidence that Dongmeng’s equipment can deliver reliable performance across different regulatory environments and material characteristics.

Mobile vs. Fixed: The Economic Case for On-Site Processing

The economic case for mobile crushing in C&D waste recycling is compelling and field-proven. Transporting demolition waste to off-site facilities incurs significant costs—haulage, landfill tipping fees, and the purchase of virgin aggregates for replacement. A mobile crushing station eliminates these costs by processing material exactly where it is generated. The global mobile crushers and screeners market was valued at approximately USD 3.3 billion in 2025 and is projected to reach USD 5.51 billion by 2032, growing at a CAGR of 7.6%. The construction waste crushing equipment market specifically is expected to reach USD 3.27 billion by 2032 at a 4.8% CAGR, driven by stricter environmental regulations, rising demand for recycled aggregates, and increasing investment in urban renewal. Industry analysts note that mobile and modular crushing equipment is becoming more popular because it can be deployed directly at demolition sites, reducing transportation costs and improving processing efficiency. For contractors and recyclers, the return on investment for a tracked mobile crushing plant is typically achieved within one to two years through savings on haulage and disposal costs alone.
