EPS Compactor – EPS Recycling
Turn Your EPS Waste into Value
EPS is better known under other names, such as airpop or styrofoam. This versatile material serves various purposes, from insulation to protecting products during transportation. The light but expansive material is not biodegradable, and when not compressed, it often ends up in landfill, creating significant problems. However, by selling compacted EPS blocks, you can generate an income. Hence, compacting the EPS creates a win-win situation for your business and the environment.
EPS Compactor for Recycling
EPS waste can be compacted at the ratio of 50:1 with our RUNI styrofoam compactor. If 50 trucks were needed to take the EPS waste to landfill before compaction, only one truck will be needed after compaction. The compacted blocks can be stacked on a pallet and sold for EPS recycling. Approximately 20 tonnes of EPS blocks can be loaded on a truck or in a container. TURN WASTE TO VALUE!
Our RUNI styrofoam densifier has an energy-efficient design, distinguishing it from other styrofoam densifier manufacturers. Unlike other manufacturers of styrofoam densifiers, the RUNI styrofoam compactor does not add any additional heat to the process; instead, the EPS waste generates the necessary heat through friction.
Different Kinds of EPS Waste
EPS comes in different qualities depending on the application and manufacturer. Density, fire retardants, and the shape of the material determine what RUNI styrofoam densifier you need.
We have seen EPS with a density from 10 grams per litre up to 100 grams per litre. Most types are between 20-35 grams per litre. The density particularly affects the compactor's capacity per hour and whether a pre-crusher with a larger motor is required.
The Shape of the Material
RUNI continues to develop styrofoam densifiers to meet demands for the different sizes and shapes of EPS material. Through dialogue with our customers on the flow of the scrap EPS, we are constantly enhancing the possibilities of handling different types of EPS products.
Types of EPS Screw Compactors
Five models have been developed by RUNI to meet the different capacities and material flow of EPS.
- RUNI SK120 has a capacity of about 18 kg per hour and is typically fed manually. It is ideal for an annual volume of less than 10 tonnes per year.
- RUNI SK200 has a capacity of about 45 kg per hour and is typically fed manually. It is ideal for an annual volume of 10 to 30 tonnes per year.
- RUNI SK200TWIN has a capacity of about 90 kg per hour and is typically fed manually. It is ideal for an annual volume of 50 tonnes per year.
- RUNI SK240 has a capacity of about 75 kg per hour and can be fed manually or by a conveyor belt. It is recommended for an annual volume of 30-50 tonnes per year.
- RUNI SK370 has a capacity of about 200 kg per hour and can be fed manually or by a conveyor belt. It is recommended for an annual volume of 50 tons or more.
For SK240 and SK370 styrofoam densifiers, a number of different hoppers, pre-crushers, silos, sensors, and block dividers for cutting the blocks automatically are available. All these options are to optimize the working flow and to adapt the solution to the required application. Whether placed at the end of a conveyor belt or integrated into your facility's internal flow, our EPS compactor ensures seamless integration and optimization of your recycling process.

- What is an EPS compactor?
An EPS compactor is a machine designed for the purpose of compacting Expanded Polystyrene (EPS) foam, commonly known as Styrofoam.
The screw compactor works by reducing the volume of EPS foam through compression. The compacted EPS takes up significantly less space, making it easier and more cost-effective to transport and handle for recycling purposes.
The compactor’s incorporated pre-crusher breaks down the EPS into smaller pieces, which then falls into the screw house. The screw and jaws press the air out of these pieces, reducing their size and increasing the density of the material. The resulting compacted EPS blocks or logs are more manageable for recycling facilities.
The use of EPS compactors helps address the environmental impact of EPS by facilitating its recycling and reducing the amount of space it occupies in landfills. Recycling compacted EPS contributes to sustainability and the responsible management of plastic waste.
- Can styrofoam be compacted?
Yes. With an EPS compactor, expanded or extruded styrofoam can be compacted into blocks and then recycled into polystyrene.
The compactor reduces the volume of the EPS at a 50:1 ratio and delivers the compacted material as blocks, that can easily be managed and sold to recycling companies.
The volume reduction makes the transportation of the waste EPS significantly more cost-effective and contributtes to more efficient waste management.
