EPS foam is one kind of common recycling material, our EPS foam recycling solution is efficient and environmentally friendly, including EPS foam cold press recycling machine, EPS foam fuse machine, plasticization, pelletizing and drying. PLC intelligent system realized high automatic, the whole line just needs 2-3 man to operate. With over 20 years of experience in recycling, Wanrooetech not only mastered the key technology but also improved machine designs to address specific product features. Wanrooetech offers EPS recycling solutions that are high output and low energy consumption.


What is EPS?

Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam. It is usually white and made of pre-expanded polystyrene beads. Due to its technical properties such as low weight, rigidity, and formability, EPS can be used in a wide range of different applications. Its market value is likely to rise to more than US$15 billion by 2020.

Thermal conductivity is measured according to EN 12667. Typical values range from 0.032 to 0.038 W/(m•K) depending on the density of the EPS board. The value of 0.038 W/(m•K) was obtained at 15 kg/m3 while the value of 0.032 W/(m•K) was obtained at 40 kg/m3 according to the data sheet of K-710 from StyroChem Finland. Adding fillers (graphites, aluminum, or carbons) has recently allowed the thermal conductivity of EPS to reach around 0.030–0.034 (as low as 0.029) and as such has a grey/black color which distinguishes it from standard EPS. Several EPS producers have produced a variety of these increased thermal resistance EPS usage for this product in the UK & EU.


Why do we need EPS recycling?

Styrofoam (EPS) has excellent durable insulation, unique buffer shock resistance, aging resistance and waterproof, therefore in the construction, packaging, electronic products, ships, vehicles and aircraft manufacturing, decoration materials, building construction and other fields has been widely applied, a great convenience to our life. But more than 50% of them are electronic cushioning packaging, fish tank and agricultural products such as packaging, these products are abandoned after one-time use, because of EPS bacteria resistance, weather resistance, corrosion resistance, 300 years to fully biodegradable under aerobic conditions, a large number of abandoned foamed plastic scattered in the natural environment, be living environment of the earth “white pollution”.

waste eps foam recycling


At present, the world produces about 12 million tons of polystyrene foam each year, of which China produces about 1.8 million tons. Except for a few developed countries, the waste PS foam material has not been effectively recycled in most countries and regions. According to incomplete statistics, the recycling rate of PS foam in Nordic countries and Japan is 72%, that in South Korea is 64%, and that in other countries and regions is only 10-30%. In China, 70 percent of the waste is buried or incinerated and only 30 percent is recycled due to inadequate recycling mechanisms.

How to recycling EPS foam?

Option 1: EPS Foam Cold Press Recycling Machine+ Shredder + Single-Stage Rigid Plastic Pelletizing  Machine

Due to the low density of polystyrene foam, it is not economical to collect. So it needs to be processed by EPS cold press, the compressed EPS foam block is easy to transport, the compressed EPS foam block can be shredded by shredder, and then the eps foam can be turned into new plastic granules by plastic granulator.

EPS Foam Cold Press Recycling Machine:
Compacting expanded polystyrene with a density of 10g/l to 100g/l at a ratio up to app 50:1. Save costs for transport and landfill, save space and handing by dealing with theEP5 in a quick and efficient manner, generate income from sales of the compacted EPS blocks, and save power consumption as no heat is added to the process. will waste EPS blocks into the hopper, cutting material block volume cutting t0 20 mm t0 50 mm size sheet foam block the compressor is used in the hopper at the bottom of the spiral compression foam block compression, discharging mouth extrusion compressed foam pad.


EPS Foam Shredder
Shredding of EPS foam blocks using single-shaft shredders, shredding into 30-50 mm plastic blocks for volume reduction.


Single Stage EPS Foam pelletizer
Mainly suitable for raw materials clean or single, stable components, water and fewer impurities, without secondary plasticization and multiple exhaust and filtration of raw materials extrusion granulation. eps foam containing water and fewer impurities quality, so the use of single-stage waste plastic pelletizer can be.

Option 2: EPS Foam Fuse Machine+ Second Stage Screw Extruder+ noodle-type plastic pelletizing

If there is no requirement for EPS transportation, you can directly choose the eps foam fuse machine, using the eps foam fuse machine to melt the eps foam, and then use the second stage extruder, using the noodle-type plastic pelletizing.


EPS Foam Fuse Machine:
The twin shaft crushing blades are two parallel blade shafts with different rotation directions. Each blade shaft has 18 blades and is driven by the gearbox to crush material that will be conveyed to the barrel through the screen. The material will be sent by the high-speed rotary screw to the heating barrel Then they will be melted under high temperatures and extruded to the expected Shapes


Second Stage Screw Extruder:

The second-stage extruder uses an extruder with a relatively small length-to-diameter ratio to further plasticize the feed and filter impurities for stable extrusion recovery.


Noodle-type plastic pelletizing :

noodle type plastic pelletizing machine is used for strip cutting process, i.e. molten polymer is solidified into a cylindrical shape, dried and then cut into easy-to-handle plastic particles.


EPS Recycling Final Products:

Through the above two EPS foam recycling methods, EPS foam through granulation, the final can get new eps new particles, can be made into other new products into use, to achieve EPS foam waste to treasure.
