Only break non-deposit-disposable bottles
Plastic deposit-free non-returnable bottles are disposed of in the bin or in a sack. As garbage is charged ever higher, any reduction in volume is welcome. Plastic bottles can be simply mechanically shredded in the household. Theoretically, a melting of PET bottles is conceivable, but produces unhealthy and usually unpleasant smelly vapors.
Refillable bottles and refilled one-way bottles are either refilled after disposal or shredded to be reused as recycling material. The deposit return system requires logistical and technical reasons, the empties remain in the original form and a barcode remains machine readable. Therefore, shredding plastic bottles before returning them is not possible.
If plastic bottles are to be shredded, several tools are available, which should also be selected according to the wall thickness of the bottles:
Normal household scissors for thin and medium-strong bottle walls
- Tailor scissors for medium-sized bottle walls
- Wire scissors for thick and stable bottle walls
- Garden and hedge trimmers for all wall thicknesses
- Powerful document shredders with prior rough cutting
- Cutting techniques
Thin and medium-walled plastic bottles can usually be crushed and wrinkled. After deformation, edges usually form, which are well suited as an approach for cutting tools.
If the plastic bottle is difficult to deform, attach the cutting tool to the neck of the bottle from the top. The first cut may require increased effort because a bottle thread develops a statically higher resistance. In order to facilitate efficient shredding, it is advisable to cut the plastic bottle approximately halfway along its length. Halb The half-shells can then be cut into narrow plastic bands with transverse cuts. In order to produce bottle wall parts for insertion into a shredder, usually a longitudinal division of the half-shells is sufficient.
Tips & Tricks When working with plastic bottles, wear work gloves to protect your hands from the sharp edges of plastic parts. Rinsing gloves made of rubber do not protect against cuts.
