PET Bottles Beverage Liquid Dewatering

The wide application of PET bottles in the beverage industry has resulted in large quantities of waste bottles, which need outdated beverage recycling. Waste PET bottles come from daily consumption of bottle-packed drinks, line-rejected, returned and date expired PET bottle beverage products in factories, and so on.

And it’s a big problem for all beverage producers to deal with the massive waste of PET bottles because there are liquids remained in the bottles and the bottles waste storage and transporting space. Aiming at this marketing needs, GREENMAX dewater machine Poseidon Series, which is specially designed for compacting containers like PET bottles, aluminum cans and so on.

Current Situation of PET bottle

PET is a highly crystalline polymer in milky white or light yellow, with a smooth and shiny surface. PET has good properties of creep resistance, fatigue resistance, and abrasion resistance. It also has the best toughness among all the thermoplastics and little affection from the temperature.

As a kind of non-toxic plastic, PET is used as a raw material for making packaging such as bottles and containers to packaging a wide range of food products and consumer goods, such as soft drinks, alcoholic beverages, pharmaceutical products, detergents, cosmetics, and edible oils.

GREENMAX Bottles Dewatering Solution

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 the 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.
