PET Bottles Beverage Liquid Dewatering

PET (Polyethylene Terephthalate) is a highly crystalline, non-toxic thermoplastic polymer with a smooth, glossy surface and excellent mechanical properties. It offers outstanding creep resistance, fatigue resistance, abrasion resistance, and toughness while maintaining stable performance across a wide temperature range. These characteristics make PET an ideal material for manufacturing bottles and containers used to package a wide variety of products, including soft drinks, bottled water, alcoholic beverages, pharmaceuticals, detergents, cosmetics, and edible oils.


The widespread use of PET bottles in the beverage industry has created growing recycling challenges. Waste PET bottles are generated from post-consumer beverage containers, production line rejects, returned products, and expired bottled beverages. For beverage manufacturers and recyclers, handling these large volumes of PET bottle waste can be difficult due to residual liquids inside the bottles and the large storage and transportation space required for bulky containers.

GREENMAX Bottles Dewatering Solution

GREENMAX developed Poseidon Bottles Dewatering Machine, which is specially designed to process PET bottles, aluminum cans, and other beverage containers. The machine removes residual liquids while compacting containers into a much smaller volume, helping businesses reduce storage requirements, lower transportation costs, improve recycling efficiency, and support more sustainable waste management.

With GREENMAX PET bottle recycling solutions, the process becomes fully automated and much more efficient. Operators only need to start the system and feed PET bottles into the hopper, and the machine handles the rest. During operation, remaining liquids are efficiently separated and removed through a built-in dewatering process, while the bottles are simultaneously compressed to significantly reduce their volume.




After process, 85%-95% of the liquids are extracted from the bottles and they are collected into a tank. Before draining out, they would be treated first in order to avoid water pollution. As for the compacting effect, the bottles’ volume ratio before and after compacting is around 10:1.



Applications of Recycled PET Bottles

Recycled PET bottles play a key role in the global circular economy, where they are collected, sorted, washed, dewatered, and compacted into bales before being processed into recycled PET flakes and fibers. These materials are widely reused across multiple industries, including textile manufacturing, packaging, carpets, automotive parts, and construction materials. Without these downstream applications, PET bottles would remain low-value waste plastic even after dewatering and compaction.
