HDPE Container Recycling Solution (Rigid HDPE/PP)
High-efficiency recycling for rigid HDPE/PP containers: drums, crates, bottles, and industrial packaging. Crushing, intensive washing, sink-float separation, and optional pelletizing deliver high-purity regrind or pellets for reuse.
- High-purity HDPE/PP regrind or pellets
- Oil and grease removal for oily containers
- Crushing optimized for rigid structures
- Sink-float tuning for material separation

Typical Process Flow
Crushing & pre-wash — Size reduction for rigid containers; pre-wash removes loose contamination and starts oil/grease breakdown.
Hot wash & friction wash — Detergent and heat remove oils and organics; friction wash adds mechanical cleaning for stubborn residues.
Sink-float & drying — Density separation isolates HDPE from PP and contaminants; dewatering and drying prepare for pelletizing.
Key Outputs & Quality Targets
Output form
Clean HDPE/PP flakes or pellets; regrind suitable for blow molding and injection.
Oil / grease removal
Detergent hot wash and friction wash target oil and grease contamination.
Optional add-ons
Wear-resistant blades, sink-float tuning, optical sorting, throughput scale-up.
Standard Line Configuration
Engineering Notes
How is oil contamination handled?
Detergent hot wash with alkaline chemistry breaks down oils; friction wash adds mechanical action. Dwell time and temperature are tuned for your contamination level.
How do you select detergent?
Alkaline detergents for oils and organics; we recommend based on your residue type and water hardness.
How is sink-float tuned?
Density of the medium is adjusted to separate HDPE (sinks) from PP (floats) and contaminants. Medium density typically 0.95–1.0 g/cm³.
What about wear parts?
Crusher blades and wash paddles use wear-resistant materials. We specify based on your throughput and material hardness.
What throughput range is available?
300–1500 kg/h typical for rigid container lines; higher capacities with parallel modules.
