Compacting Technologies of Polyethyleneterephtalate Bottle

Abstract:

The waste production is increasing owing to an economical development of the society. In the area of a communal sphere they are namely PET (polyethyleneterephtalate) bottles. The research aim was to evaluate methods of compacting the drinking PET packaging. The plastic drinking packaging waste is distinguished for its dominant representation. Owing to its construction it takes up a front place in low efficiency of a storing and transporting space comparing with a material yield. The efficient compacting of the drinking packaging leads to solving a problem with often fulled up containers. The volume decreasing by means of the compacting of the packaging waste can be done in a few ways. A basic sortion is a manual pressing without the press, second way is using the mechanical presses. A low efficiency of the packaging materials is one of essential problems from the sustainable progress of human society point of view. Statistical methods were used for evaluating results and deducing conclusions. The most often used PET drinking packaging (the volume 0.5 l, 1.5 l and 2.0 l) was evaluated. The volume of the bottle before compacting and after it was set on the base of a level uplift in a calibrated laboratory tub coming from the Archimedes´s law. Experiment results showed that an effective compacting rate was reached by a manual press
