Separation and compacting Tetra-pak

RUNI screw compactor empties and compacts Tetra-pak in one process. 100% destruction is ensured and at the same time cost for waste handling is reduced.

Breweries and other manufacturers of beverages like juice, soft drinks, smoothies and other products in Tetra-pak destroy returned goods with expired date and faulty manufacture to avoid the products being resold by mistake

RUNI screw compactor handles both destruction, separation and compacting in one process  saving storage and handling at the manufacturer. Installation of the compactor close to the production increases certainty of destruction and saves transport cost.

During separation the waste stream is split in two. The liquid can be discarded as waste water or in some cases it can be collected and sold for other purposes  - energy production or animal feed. The solid is now so dry it can go to to incineration at lower cost or sold to recycling.

The material is fed manually or with conevyor belt. The liquid is pressed through a hole matrix and the compacted material is slowly pushed out of the departure tray.

The hole matrix is made of stainless steel to withstand liquid with low pH.
