1.2 Washing Systems

• High-Speed Friction Washers:
  • Remove labels and contaminants via intense agitation. Retech’s model (1,000 kg/hour) costs $35,000 .
• Hot Washing Lines:
  • For food-grade applications, like Tecnofer’s system (2.5 tonnes/hour), which reduces water usage by 30% and costs $150,000+ .

1.3 Drying and Dewatering

• Screw Dryers: Efficiently remove moisture. Tomra’s water-ring dryer (1,000 kg/hour) adds $15,000–$30,000 to total costs .
• Centrifugal Dewatering: Reduces moisture content to <5% for PET flakes .

2. Price Range by System Configuration

2.1 Small-Scale Systems (50–500 kg/hour)

• Lab/Pilot Lines:
  • For R&D or small businesses. Huaming Machinery’s lab system (5–20 kg/hour) costs $9,500–$10,000 .
• Mini Production Lines:
  • Handle clean PE films. Fosita’s PP PE line (300 kg/hour) with pre-wash and drying: $27,000 .

2.2 Industrial-Scale Systems (1–5 tonnes/hour)

• Standard Lines:
  • Process PET bottles or HDPE containers. Plastar’s PE/PP film line (1,500 kg/hour) with AI sorting: $20,000–$80,000 .
• Advanced Lines:
  • Include closed-loop washing and IoT monitoring. Beston BFX-200 (1–5 tonnes/hour): $130,000+ .

2.3 Specialized Systems

• PVC Shredding Lines:
  • Handle rigid plastics. SJSZ-65/132 PVC line (150 kg/hour) with degassing: $20,000 .
• Bio-Plastic Washing Systems:
  • Process PLA and biodegradable materials. Retech’s WPC line (120 kg/hour): $12,000–$12,598 .

3. Key Factors Influencing Prices

3.1 Material Type and Contamination

• Clean Plastics (e.g., PET bottles):
  • Lower processing costs ($15,000–$50,000 for a 300 kg/hour line) .
• Mixed/Contaminated Plastics:
  • Require advanced sorting (e.g., AMP Robotics Cortex™ AI-sorted line: $50,000+), increasing costs by 20–40% .

3.2 Automation and Energy Efficiency

• Manual Systems:
  • Lower upfront costs ($10,000–$30,000) but higher labor expenses .
• Fully Automated Lines:
  • Reduce energy use by 25% (e.g., MSS Cirrus® IoT system) but cost 20–40% more .

3.3 Brand and Quality

• Premium Brands (e.g., Coperion, Vecoplan):
  • Offer 5–10 year warranties and CE/ISO certifications, with prices 20–30% higher .
• Chinese Suppliers (e.g., Purui Machinery):
  • Cost-effective solutions ($2,000–$50,000) with shorter lead times .

4. Cost-Benefit Analysis

4.1 Financial Returns

• Material Recovery:
  • Clean PET pellets sell for $800–$1,200/tonne, while HDPE fetches $600–$900/tonne .
  • Example: A 300 kg/hour line processing PET bottles generates $72,000–$108,000 monthly revenue at full capacity .
• Energy Savings:
  • Hybrid systems (e.g., Tomra’s PET line) save $5,000–$10,000 annually in electricity costs .

4.2 ROI Timeline

• Small-Scale Lines:
  • Pay off in 1–2 years through reduced disposal costs and material sales .
• Industrial Lines:
  • Achieve ROI in 3–5 years due to higher throughput and premium material prices .

5. Choosing the Right Equipment

1. Material Compatibility:
   • PET Bottles: Opt for lines with label removers (e.g., Kodak CRSTA-RECYCLING) .
   • Mixed Plastics: AI-sorted systems (e.g., AMP Robotics Cortex™) are ideal .
2. Throughput Requirements:
   • Small-Scale: 50–500 kg/hour (e.g., Sanhuiying SJ65) .
   • Industrial: 1,000–2,000 kg/hour (e.g., Beston BFX-200) .
3. Budget Constraints:
   • Low Budget: Chinese suppliers on Alibaba offer basic lines starting at $2,000 .
   • High Budget: Invest in IoT-connected systems for scalability .
4. Sustainability Goals:
   • Energy Efficiency: Hybrid systems reduce carbon footprints by 30% .
