This line specializes in recycling rigid high-density polyethylene (HDPE) milk bottles into clean, reusable flakes or pellets. Designed for dairy packaging waste, it removes contaminants like milk residues, labels, adhesives, and dirt.
The system combines shredding, intensive washing, and drying stages to produce high-purity HDPE material. Output meets food-contact or non-food manufacturing standards, supporting circularity in packaging industries.
Built for efficiency, the line emphasizes water recycling, energy conservation, and minimal waste generation. It scales seamlessly for small to large recycling facilities (300–2,500 kg/h).

Key Features

Heavy-Duty Shredding: Robust crushers process rigid HDPE bottles into uniform flakes.
Multi-Stage Washing: Pre-wash, hot wash (60–80°C), and chemical cleaning eliminate organic residues and adhesives.
Label & Cap Removal: Dedicated separators detach PP/PE labels and residual caps during pre-processing.
Friction Scrubbing: High-speed scrubbers polish flakes for contaminant-free output.
Water Recycling: Closed-loop systems reduce freshwater consumption by up to 70%.
Thermal Drying: Low-energy dryers achieve moisture levels below 1% for pelletizing.
Food-Grade Compliance: Optional UV sterilization ensures suitability for food-contact applications.
Automated Sorting: Pneumatic systems or sensors remove non-HDPE materials (e.g., PVC, metals).

Process Workflow

Pre-Sorting: Manual removal of non-HDPE items (e.g., caps, foreign plastics).
Coarse Shredding: Bottles are shredded into 10–15 mm flakes.
Pre-Washing: Removes loose dirt and residual liquids with ambient water.
Hot Alkaline Wash: Dissolves milk fats and organic residues.
Friction Wash: Mechanical scrubbing removes embedded contaminants.
Float-Sink Separation: Tanks separate HDPE (floats) from denser plastics (e.g., PVC).
Rinsing & Dewatering: Flakes are rinsed and spun-dried.
Thermal Drying: Hot air reduces moisture to <1%.
Pelletizing (Optional): Flakes are melted, filtered, and extruded into pellets.
Packaging: Material is stored in silos or bagged for industrial reuse.
