TRADE SHOW PREVIEW PET planet Insider Vol. 18 No. 09/17 www.petpla.net 80 Emptying and compacting of PET bottles Ready to be recycled With the strapline `fast and economical compaction´ Strautmann will be presenting different waste disposal solutions. The dewaterer LiquiDrainer and the baler BaleTainer will be the principal focus of the company’s exhibits. The emptying of PET bottles will be demonstrated live at Strautmann’s booth. With the dewaterer `LiquiDrainer´ beverage containers like PET bot- tles can be emptied and devalued. The LiquiDrainer pricks the bever- age containers so that the liquids flow out. The material is perforated and not shredded. Thus there is no wear on the rotor. The residual liquids pass through a coarse filter and can be subsequently sold for example to biogas plants. Thanks to the separa- tion of liquid and packaging no parti- cles enter the wastewater. In the next step the material is compacted with bale or briquetting presses. The fully automatic compac- tion of the beverage containers into high compacted bales und briquettes saves space and costs. Recyclable materials can be sold profitably. Disposal solution at Hansa-Heemann Hansa-Heemann AG, manufac- turer of non-alcoholic soft drinks with several production locations in Germany, offers a complete disposal solution for PET, cardboard and film. At their Löhne site 400 million bever- age cans are filled in a three-shift operation. Prior to their decision to use Strautmann Umwelttechnik for PET bottle disposal, Hansa-Heemann had already been compacting film and cardboard with Strautmann presses for more than seven years. “While producing mineral water and sweet beverages residual liquids need to be disposed of economically and ecologically. Our PET bottles are now drained and compressed eco- nomically by using the Strautmann LiquiDrainer and BaleTainer” says Thomas Hartsieker, Plant Manager, Hansa-Heemann AG. Disposal process The now compressed PET bot- tles are collected in Hansa-Heemann containers and lattice boxes and then brought to the outside waste disposal area. Here, using a fork- lift an employee lifts the boxes and empties them into the hopper of the LiquiDrainer. Via a conveyor belt, the PET bottles are transported into the LiquiDrainer, which empties and devalues them. The emptied and already pre-compressed PET bottles are transported from the LiquiDrainer directly into the fully automatic baler BaleTainer, prior to being compacted directly into marketable bales. Before installing the LiquiDrainer solution, the process was handled by a disposal company. Emptying of 120 bottles/min With the LiquiDrainer, the manual emptying of PET bottles is eliminated. Employees are able to focus on the core business and work faster and more efficiently. Thanks to special rotor technology and a throughput of up to 7,000l/h, approximately 120 bottles can be emptied in one minute. The beverage containers are emptied and devalued to prevent fraudulent re-use. Baler compacted “Cardboard, film and PET were pre- viously stored in troughs with a filling capacity of 7-30m³. Up to 15 troughs were positioned inside the production area and warehouse. The material col- lected was inserted manually. Because the material was inefficiently collected, the troughs were filled very rapidly, and they needed to be placed outside to be picked up constantly.” remembers Ender Yilmaz, Disposal, Hansa-Hee- mann AG. “In one trough about 500kg of loose film was accumulated.” With compaction by a baler now about 8-10t can fit in one trough. In production three multi-chamber balers now give an impression of cleanliness and order. The presses enable sorted compaction of card- board and film. The high-compacted bales of the presses are then taken to a hopper by a forklift truck and picked up by the disposal company. The installation of the balers directly at source eliminated a lot of unneces- sary walkways and made the work more efficient. www.strautmann-umwelt.com Hall B4 - Booth 512 Filling of the dewaterer LiquiDrainer The LiquiDrainer pricks the PET con- tainers so that the liquids flow out.
