XPS Compactor - Extruded Polystyrene
XPS (extruded polystyrene) is a lightweight and bulky material with a high air content. This contributes to the material’s insulating properties – but also makes it challenging and costly to handle, especially when it comes to storage, transport, and disposal.
With a screw compactor from RUNI, XPS foam can be transformed into compact, stable blocks that can be sold for recycling.

What is XPS Waste
XPS (Extruded Polystyrene) is a foam material widely used in the construction industry. It has a firm structure and is often used as a base for heavy construction. It can be used as insulation for flat roofs or as protective packaging for furniture during transport.
XPS contains a great deal of air, which makes it suitable for compacting. This is a good solution in connection with building demolition or for manufacturers of XPS containing elements with off-cuts or faulty manufacture that must be disposed of.
Recycling extruded Polystyrene
The cost of transport and handling can be reduced significantly by compacting the material at the source. The compacted XPS blocks can be sold for recycling instead of ending up being expensive regular waste.
RUNI XPS Compactor
RUNI has a model of the SK370 screw compactor with extra equipment for dealing with the XPS because its structure makes it difficult to compact. When the XPS is fed into a Heavy Duty pre-crusher, it is crushed into smaller pieces, and the screw and hydraulic jaws compact it into uniform blocks. These blocks can be stacked on a pallet. The machine can be fed manually into a 45° hopper or with a conveyor belt into a vertical hopper. The different incorporated sensors ensure easy operation with automatic start and stop functions. It is also possible to install the compactor below a silo for XPS dust or smaller pieces.
Case Studies
Selit uses 2 SK370s to compact their XPS and EPE cut-offs in order to optimize the recycling of the materials.
