Munich’s RecycleTech tripled PET recovery rates using 120-ton horizontal balers – crushing 18,000 bottles/minute into 480kg bales that meet EU 2025 Circular Economy standards.
Horizontal balers process PET bottles through smart compression (220-380kN force) and anti-contamination systems achieving 99% purity. Key features: 3-phase automation (loading/crushing/ejection), 1.2mm crush tolerance, and real-time TOP₂ sensors blocking PVC ≥0.5%. The HX-PET Pro processes 6.8t/hour with 1.4% metal residue – critical for food-grade recycled PET.
Unlock five operational secrets behind effective PET recycling.
Which Manufacturing Process Is Used to Make PET Bottles?
Osaka’s BottleWorks produces 2.8 million PET bottles daily using stretch blow molding – a process creating recycling complexities most operators ignore.
PET Production & Recycling Impacts
| Production Stage | Recycling Challenge | Horizontal Baler Solution |
|---|---|---|
| Preform Injection | Gate remnants (0.4-1.2g) | Metal detectors@Φ1.5mm sensitivity |
| Stretch Blow | Stress cracks | 4-layer compression plate design |
| Labeling | Adhesive contamination | 80°C pre-heat plate de-bonding |
| Capping | PP/PE mixing | Near-infrared (NIR) auto-sorting |
PET Grade Recognition
| Resin Code | Use Case | Bale Value (€/ton) |
|---|---|---|
| PETG | Medical | 620-680 |
| PET1 | Beverage | 480-540 |
| PET-C | Custom | 310-380 |

How Do You Process PET Bottles?
Taipei’s GreenLoop achieved 99.97% pure PET flakes using horizontal balers with seven-stage sorting – proving automated processing beats manual methods.
Industrial PET Recycling Workflow
Stage 1: Pre-Sorting
- Overband magnet (12,000 Gauss)
- Eddy current separator (non-ferrous)
- 40mm disc screen (cap removal)
Stage 2: Baling Prep
- 110°C steam wash (label removal)
- Rotary shear (bottle flattening)
- Moisture control <0.08%
Stage 3: Smart Compression
| Parameter | Standard | Advanced |
|---|---|---|
| Force | 220kN | 380kN |
| Cycle Time | 4.8 min | 3.1 min |
| Temperature | Ambient | 65°C |
| Residual Air | 12% | 3.8% |
Operational Results (Jakarta):
- Output: 8.2t/day → 14.7t/day
- Flake purity: 96% → 99.5%
- Energy cost: €11.3 → €6.8/ton
