3. Key Factors Influencing Prices

3.1 Material Type and Contamination Level

• 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 and washing, increasing costs by 20–40% .
  • Example: AMP Robotics Cortex™ AI-sorted line (500 kg/hour): $50,000+ .

3.2 Automation and Energy Efficiency

• Manual Systems:
  • Lower upfront costs ($10,000–$30,000) but higher labor expenses .
• Fully Automated Lines:
  • Include IoT monitoring (e.g., MSS Cirrus®) and reduce energy use by 25%, but cost 20–40% more .
  • Example: Tomra’s PET Line (1,000 kg/hour) with closed-loop water system: $150,000+ .

3.3 Brand and Quality

• Premium Brands (e.g., Coperion, Vecoplan):
  • Offer 5–10 year warranties and CE/ISO certifications, but prices are 20–30% higher .
  • Example: Coperion’s twin-screw line (2,000 kg/hour): $200,000–$500,000 .
• Chinese Suppliers (e.g., Purui Machinery):
  • Cost-effective solutions ($2,000–$50,000) with shorter lead times .

4. Cost-Benefit Analysis

4.1 Financial Savings

• 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 Efficiency:
  • Hybrid systems (e.g., Tomra’s PET Line) save $5,000–$10,000 annually in electricity costs .

4.2 ROI Timeline

• Small-Scale Lines (e.g., $15,000):
  • Pay off in 1–2 years through reduced disposal costs and material sales .
• Industrial Lines (e.g., $130,000):
  • Achieve ROI in 3–5 years due to higher throughput and premium material prices .

5. Choosing the Right Pelletizing Line
