The plastic bottle shredder with bicycle trainer


Energy needed to power the shredder is generated by a person pedaling on a bicycle. Grinding 1 bottle of 1.5 liters takes about 20 seconds.


The plastic bottle (PET) shredder powered by EnergyBike, is a device that fits into the ecological lifestyle trend. Nowadays, when the utilization of plastics is becoming a global problem, it is important to be able to process plastic waste at least on a small scale. Thanks to the shredder, plastic bottles and other plastic containers can be ground into small pieces, and then given a thermal treatment to create raw material for secondary use. For example, a filament for a 3D printer. Pedaling on an EnergyBike produces the energy needed to power the device. The cover and hopper of the shredder are made of transparent polycarbonate so that we can watch how a bottle gets between the blades and is cut into small pieces.

The trainer used in the set is equipped with a modular drive belt. Innovative power transmission through modular drive is much more efficient than a traditional pressure roller trainer. An additional advantage is easy and quick assembly and disassembly of the belt – without removing the bike wheel or tire. Just unfasten the belt and place it on the rear tire and roller on the back of the trainer. When disassembling, unfasten and remove the belt.
