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 Manufacturer

Huaming Machinery’s prices seem pretty reasonable compared to other brands. Might check them out for our small plant.
Does anyone have experience with Dongguan Keda’s customized lines? Wondering if their AI sorting actually works well.
$150k+ for a Tomra system 😳 That’s like twice my annual budget!
The part about water conservation is crucial. Our recycling plant cut costs by 40% after switching to closed-loop systems.
Chinese manufacturers are really stepping up their game with those ISO certifications and competitive pricing.
@MeadowRoamer：Not just pricing, their quality control has improved dramatically in recent years. Ordered a line from Zhangjiagang last quarter and it exceeded expectations.
Wait, they can get ROI in 1-2 years? That seems too good to be true 🤔
Just visited Jiangsu Gangsu’s factory last month – their throughput is insane! The 10,000 kg/hour line blew my mind.
Great guide! Bookmarked for when we upgrade our equipment next year.
@GrimReaper：Same here, this is exactly what we need for our expansion project. Let me know if you find any hands-on reviews!
The nanotechnology heating section got me interested. Any manufacturers already implementing this?
Our plant uses Coperion’s twin-screw washers – worth every penny for the 10-year warranty.
OMG the prices vary so much, how do I know which one’s actually worth the investment? 🤔
Huaming’s lab system at $9.5k sounds perfect for our startup’s R & D phase. No more borrowing university equipment!
