In the automotive, home appliance, and logistics industries, foam is widely used as a protective packaging material, serving functions such as cushioning, waterproofing, and shock absorption.

But did you know? Not all packaging foams are the same.

For example, EPP foam is mostly used to package automotive parts; EPS foam is commonly used in cold chain transportation for seafood, such as EPS fish boxes; and EPE foam is often used for protective packaging of electronic products.

What’s the difference between EPP, EPS, and EPE foam?

EPP has high strength and excellent impact resistance. It is reusable and commonly used for packaging automotive parts that require a high level of protection.

EPS is lightweight and brittle, with good insulation properties. It is often found in packaging products such as coolers and fish boxes.

EPE is soft and flexible with outstanding shock-absorbing performance. It is widely used in the inner packaging of electronic products to prevent scratches and impacts.

If you happen to have waste packaging materials made of all three types of foam—or expect to deal with various foam recycling needs in the future—you might be worried about having to purchase separate machines for each material.

GREENMAX is here to tell you: there’s absolutely no need!

Is EPP recycling the same as EPS and EPE recycling?

Besides being used as fuel or undergoing chemical recycling, foam materials can also be transformed into recycled pellets through crushing, compacting, and pelletizing, making them suitable for reuse in production.

However, due to the different characteristics of each type of foam, the specific technologies used in the pelletizing process vary. That said, during the crushing and compacting stages, the GREENMAX Zeus EPP compactor enables multi-material processing in a single machine—handling EPP, EPE, and EPS foam simultaneously.

This polypropylene compactor is specially designed for diverse foam materials. It adopts a dual technology of screw compression + surface hot melting, enabling it to efficiently process:

    • Tough EPP foam — effectively crushes and hot-melts the material, forming stable blocks

    • Highly elastic EPE foam — thoroughly compresses with surface hot-sealing to prevent rebound

    • Common EPS foam — rapidly densifies with a compression ratio of up to 50:1

The Zeus EPP compactor offers a one-stop solution for EPP recycling and EPS/EPE recycling, helping you achieve high-value recovery from mixed foam waste.

How is one-stop expanded polypropylene recycling achieved?

GREENMAX engineers preset multiple compression modes on the polypropylene compactor tailored to different foam materials. These modes are based on parameters provided by customers—such as density and moisture content—as well as over a decade of hands-on recycling experience.

You simply select the appropriate mode with one click based on the actual material, and efficient compaction begins immediately.

No complicated training is required, and there's no need to invest in multiple machines. With just a simple mode selection on this EPP compactor, customers can easily carry out EPP recycling.

A single machine can transform various types of foam waste from bulky trash into profitable resources, delivering higher value returns.
