Separating and Compacting Tetra-Pak

Breweries and other manufacturers of beverages in Tetra-Pak, like juice, soft drinks, smoothies, and other products, often have to destroy returned goods with expired dates and/or faulty products to avoid them being resold by mistake. The RUNI screw compactor is the perfect machine for dewatering Tetra-pak.

The machine handles both destruction, separation, and compacting in one process; this saves manufacturers from storage and handling problems. Installing this compactor close to the production area increases the certainty of destroying faulty products and saves a lot of transport costs.

How Does the Screw Compactor Dewater and Compact Tetra-Pak?

When separating the liquid, the waste stream splits in two. The separated liquid can be discarded as wastewater, or in some cases, it can be collected and sold for other purposes, like being used in energy or animal feed production. After compacting, the solid becomes dry and can be sent to incineration at a lower cost or sold for recycling.

The full Tetra-Paks can be fed to the screw compactor manually or with a conveyor belt. The liquid is squeezed through a perforated matrix, and the compacted packaging material is then slowly pushed out of the departure tray and can be collected in containers.

The perforated matrix is always made of stainless steel to withstand liquids with low pH.

Note: In the food industry, the screw compactor needs to be placed away from the primary production - RUNI has several solutions for this. Sometimes cleaning of the screw compactor is essential - also here RUNI has several solutions.

Case Studies

Carlsberg Brewery

At Carlsberg in Fredericia, RUNI compactors handle PET bottles, aluminum cans, and plastic kegs – efficiently and reliably.

NEN-Produkter AS

At NEN-PRODUKTER in Norway, the RUNI SK370 made it possible to press the liquid out of filled Tetra Paks, allowing the waste to be sent for recycling instead of costly disposal. The result: significant savings on waste fees – and a solution that is both efficient and environmentally friendly.

Jasar Recycling

Jasar Recycling has installed a RUNI SK370 to dewater their PET-bottles at their East Palestine, Ohio location.
