Smarter Waste Management for Fish Boxes in Fish Processing Plants
Fish processing plants generate large volumes of EPS (expanded polystyrene) fish boxes, which are bulky, lightweight, and costly to transport and store. RUNI screw compactors efficiently crush and compact these boxes, reducing volume by up to 50:1. This not only lowers disposal and transport costs but also creates opportunities for recycling and revenue generation. With automated operation, modular design, and reliable performance, RUNI solutions help seafood processors manage EPS waste smarter, save space, and turn waste into value.

Efficient Compaction Solutions for Fish Boxes
Fish processing plants generate significant volumes of EPS (expanded polystyrene) waste through the packaging of fresh seafood. Efficient management of fish boxes is crucial not only to reduce disposal costs but also to create opportunities for recycling and generate additional revenue. However, handling large quantities of EPS can be challenging due to its light weight and bulky volume, leading to high transport and storage costs.
Effective waste management helps reduce costs, maximize space, and turn waste into a valuable resource for the recycling market.

The Challenges of Handling EPS Waste
| Challenges | RUNI's solution |
| High Transport Costs: EPS fish boxes are bulky and lightweight, increasing transport costs. | Compaction: Reduces the volume of the fish boxes by up to 50:1, making transport more cost-effective. |
| Space Limitations: EPS fish boxes takes up excessive storage space before disposal. | Space Saving: Compacted blocks are easy to store, reducing the footprint of waste storage. |
| Disposal Costs: Disposing of EPS is costly. | Revenue Generation: Sell compacted EPS for recycling, turning waste into income. |
| Environmental Impact: EPS often ends up in landfills, contributing to pollution. | Recycle: Compact and recycle EPS, reducing landfill waste and CO2 emissions. |
| Operational Efficiency: Managing EPS waste can be labor-intensive and time-consuming. | Easy Operation: RUNI machines offer automated start/stop functionality, and adjust the pressure of the screw automatically, compacting up to 200 kg/hour per machine. |

Enhance Waste Management in the Seafood Industry
RUNI screw compactors are specifically designed to handle EPS waste efficiently. Our machines work by feeding EPS fish boxes into the compactor, where they are first crushed into smaller pieces and then compressed under high pressure by a rotating screw. This compression process significantly reduces the volume of the EPS, producing cohesive blocks, making the EPS more manageable and easier to store or transport.
The compactors are available with diffent feeding options, ensuring the machine adapts to your specific needs and work flow.
RUNI compactors are available in different sizes, ensuring the right fit for any plant, whether small or large-scale, compacting from up to 18 kg/hour and up to 200 kg/hour per machine. Read more about the different sizes here.
By compacting the EPS into dense blocks, the compacted material can be easily stored or sold for recycling, creating the potential for a more sustainable operation while potentially generating additional revenue.
