Pilatusmarkt Kriens has reorganized and centralized waste disposal. PET bottles are opened and compacted in a perforator. The compression reaches at least a factor of four.
At the Pilatusmarkt shopping center in Kriens, batteries as well as containers made of glass, PET and other plastics are collected separately by type at a central location. For compacting the PET bottles, the shopping center works with a perforator from Hunkeler Systeme AG. The bottles are opened and compressed via two counter-rotating slotted drums. Bags with a capacity of 360 liters catch the bottles. An SMS notifies the personnel as soon as a specified fill level is reached in the sacks. Compared with the uncompacted material, the volume can be reduced by at least a factor of four. In absolute terms, this corresponds to a reduction from 2.88 million to 720,000 liters per year.
