The RUNI Foam Densifier Turns Your Waste into Value
RUNI Screw Compactor was originally developed to compact EPS fish boxes for the fishing industry, but it has since proved useful as a foam densifier for many other materials than styrofoam. We have succeeded in supplying many successful compacting machines and solutions in a wide range of industries - construction, fishing, waste handling etc. It is impossible to calculate the exact outcome in advance. The RUNI foam densifier compacts plastic foams, such as EPS, EPP, EPE, XPS and PUR. All these materials can be sold to produce new materials in recycled plastic. The compaction saves space and handling in warehouses and waste containers and thereby protects the environment and saves money on collection. RUNI TURNS WASTE INTO VALUE.
- What is a foam densifier?
A foam densifier refers to the compactors handling all kinds of foam; EPS, EPE, EPP, PUR, or XPS. These foams are fed into the compactor, and the air (and/or gas) is squeezed out, and most foams then comes out as a stackable block, that can mostly be sold for further recycling.
- How does a foam densifier work?
When the air is squeezed out of the different types of foam, the foams will then become blocks that are very heavy, and they can now be transported to the next point of recycling without all the air inside the materials.

When the different foam types are compacted, they are turned into a value for the company, in stead of the company having to spend great amount to get rid of it. The compacted blocks have quite a high value, and many companies worldwide are interested in buying these compacted blocks for recycling.
EPS Styrofoam Is Used Across Industries and Builds Up Large Amounts of Waste
With it's many specific qualities (light weight, shoch-absorbing, heat/cold protecting, durable, etc.). Polystyrene plastic foam is widely used across many industries. From insulating houses in the construction industry, to protecting vegetables or fish in the food industry to protecting both medicine and test within the medical industry, to mention a few.
Even though it is a very popular product, it is still not always the case that the EPS is recycled after it's use. This can be because people are not aware that this polystyrene foam is 100% recyclable, it can be because of the difficult and expensive storing and handling of this very space consuming material. This is why EPS waste often end up in incineration plants or at landfills. This is very costly for the environment at the EPS foam does not degrade naturally, and it takes up a lot of space, without having much weight.
How the RUNI Foam Densifier Recycles Loose Foam Products
When having waste foams, the optimal way of handling it is to estimate how much waste material there is, then a specific machine for these capacities can be designed, and then, whenever your company is collecting a bit of the waste foam material, for example waste EPS or EPS fish boxes, these are simply fed into the compactor. Afterwards, the compacted blocks can be stacked on a pallet for easy storing, only taking up a 50's part of what the waste EPS would take up, until you are ready to sell the pallets with the compacted material.
What to Consider When Choosing a Foam Densifier
The most important considerations when deciding on a foam densifier are; type of waste foam material, quantities that needs compacting, and specific needs for the densifier to be built into an existing line/building.
We are always at your disposal for considering these important point, and to help design the best solution for you specific need.
An example could be: An electronic store: they have used EPS from the products they sell, unpack and maybe even install at their costumers'. They have around 20 tonnes a year and they have a pallet rack in the corner of their warehouse, next to the EPS-collection-point, that would be the perfect place for their foam densifier solution.
With this information we would recommend the RUNI SK200 densifier, that would match the need of this company, and it can be placed inside the pallet rack, and thereby not take up a lot of space in their warehouse. Than they simple throw it in every time they have some waste EPS, and stack the blocks when a whole block has come out of the densifier.
