Construction waste accounts for over 30% of global solid waste, yet only 50% is recycled—presenting a massive opportunity to transform debris into valuable resources. Crusher plants offer a sustainable solution, turning concrete, asphalt, bricks, and metals into reusable aggregates and raw materials. This guide explores how crusher plants unlock value from construction waste, from equipment selection to operational benefits.
Key Equipment for Waste Processing
1-1. Mobile Jaw Crushers
- Ideal for: Primary crushing of hard materials (concrete with rebar, asphalt, bricks).
- How it works: Compressive force breaks large debris into medium-sized particles (10–150 mm).
- Example: A 100 TPH mobile jaw crusher can process 800 tons of concrete per day, producing base material for roads.
1-2. Mobile Impact Crushers
- Ideal for: Secondary crushing and shaping, creating cubical aggregates for concrete.
- How it works: High-speed impact plates break materials into uniform particles (5–40 mm).
- Advantage: Produces 90% cubical aggregates, meeting ASTM C33 standards for concrete.
1-3. Mobile Screening Plants
- Function: Classify crushed waste into different sizes (e.g., 0–5 mm sand, 5–20 mm gravel).
- Technology: Vibrating screens with 2–4 decks, achieving 95% screening efficiency.
2-1. Material Collection: Debris is sorted to remove non-crushable materials (plastics, textiles).
2-2. Primary Crushing: Jaw crusher reduces large chunks to 10–20 cm.
2-3. Secondary Crushing: Impact crusher or cone crusher further grinds to 5–10 mm.
2-4. Screening: Separates aggregates by size for different applications.
2-5. Optional Washing: Removes fines and impurities for high-quality sand.
3-1. Aggregate Production
- Road Base Materials: Crushed concrete (20–40 mm) replaces natural gravel, saving $10–$15/ton.
- Concrete Aggregates: 5–20 mm particles meet concrete standards, reducing costs by $20–$30/ton vs. virgin materials.
- Manufactured Sand: 0–5 mm particles replace river sand, addressing global sand shortages.
3-2. Metal Recovery
- Rebar and Steel: Magnetic separators extract 90+% of ferrous metals, selling for $200–$400/ton.
- Non-Ferrous Metals: Eddy current separators recover aluminum and copper, valued at $1,000–$3,000/ton.
3-3. By-Product Utilization
- Fines (0–0.15 mm): Used as filler in bricks or cement admixtures.
- Wood and Plastics: Shredded for biomass fuel or recycled into plastic lumber.
Key Considerations
4-1. Waste Composition:
- High-concrete waste: Prioritize jaw crushers.
- Mixed waste with bricks/wood: Include impact crushers and sorting systems.
4-2. Mobility Needs:
- Temporary sites: Mobile crushing plants (tracked/wheeled).
- Permanent facilities: Fixed jaw + impact crusher systems.
4-3. Output Specifications:
- Road base: Coarse crushing (20–40 mm).
- Concrete: Fine crushing (5–20 mm) with cubical shape.
5-1. Smart Crushers: IoT-integrated plants monitor wear, optimize crushing parameters, and reduce downtime by 20%.
5-2. Electric Mobile Plants: Battery-powered crushers cut emissions by 90%, ideal for urban sites.
5-3. Circular Economy Models: On-site crushing at construction projects, reducing transport and storage costs.
Construction waste is no longer a disposal problem but a resource opportunity. Crusher plants enable businesses to generate revenue from debris, reduce environmental impact, and meet regulatory demands. By investing in the right equipment—whether mobile jaw crushers for flexibility or fixed plants for high-volume processing—companies can unlock significant value while driving the circular economy.
