Oregon Beverage Recycling Cooperative Case Study

How OBRC is Optimizing Operations at their BottleDrop Centers with the Komar EPC-5.

You need excellent processing equipment when you are charged with keeping 169 million pounds of beverage containers out of the landfill annually. The Oregon Beverage Recycling Corporation (OBRC) turned to Komar to help maximize storage capacity at their drop-off locations and drastically reduce transportation costs to their processing facilities.

FAQs

While our flatteners do also remove liquid from containers, their primary purpose is to reduce output volume by crushing containers. Dewatering systems do offer similar compaction ratios but their primary function is to remove liquid from the containers to reduce output weight.

Food and beverage manufacturers and packagers, co-packers, recycling facilities, and several others all benefit from liquid separation technology.

Yes. This type of equipment is designed to process sealed containers, partial fills, and damaged packaging while safely extracting liquids.

Results depend on the types of materials being processed and the specific equipment configuration, but dewatering equipment can achieve up to 95% liquid removal.

Considerably less maintenance is required compared to screen-based systems. Regular lubrication, cleaning, and inspection are typically enough to keep them running well. Our semi-annual preventative maintenance program with a Komar expert technician is recommended but not required.

Komar equipment is designed to adapt to various feed methods and integrate with existing material handling equipment, including continuous-feed, conveyor-fed, and chute-fed layouts.

Removing liquids dramatically reduces weight, which translates to lower tipping and hauling fees.

Yes. Flatteners and dewatering systems help pre-process materials to reduce transportation and downstream baling time.

We provide complimentary waste stream evaluations to recommend appropriate equipment based on volume, material types, and operational requirements.
