Extruded plastic foams, such as DuPont's Styrofoam and generic polystyrene, are frequently used as protective padding and insulation. However, because they are completely non-biodegradable, they are typically thrown away, which is not the best use of them. The team's method converts the trash into poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), a conductive polymer used in a variety of electronic applications, rather than throwing it away.

As the recycling of polystyrene has attracted more and more people's attention, recycling methods have become endless, including new chemical recycling methods, biological recycling methods and mechanical recycling methods. This means that polystyrene recycling will become increasingly popular and diverse. The chemical recycling method mainly converts expanded polystyrene into another chemical substance, achieving a qualitative change. The characteristics of this recycling method are that it achieves large changes and the new substances extracted are of high purity. The disadvantage is that it requires high technology and cannot be popularized.Mechanical recycling method mainly makes polystyrene into new plastic products. The purity is not as high as chemical recycling method. Compared with new raw materials, it can only become "recycled material". However, this recycling method can help solve white pollution on a large scale , and the feasibility is very high. Anyone can use the equipment to recycle, realizing true universal recycling.

One of the devices that is simpler to operate and has better compression performance is the polystyrene melting machine. These are the two main advantages of this device. First, start the equipment preheating. You can adjust the required equipment parameters by touching the screen. If you don't know how to adjust, you can consult GREENMAX engineers and provide the specific conditions of the waste materials, and we will give a suitable operation plan. Next, the waste expanded polystyrene is put into the feeding bin of the polystyrene melting machine and then crushed. These crushed flake polystyrene are then heated, melted and extruded to achieve high-strength compression. After compression, these wastes will become 1/90 of their original volume and become dense, recyclable foam ingots.

In the process of operating the polystyrene melting machine, no strong technical skills are required. 1-2 workers are required to operate the machine on site to achieve smooth compression. It should be noted that the temperature of polystyrene that has just been compressed is relatively high. You need to pay attention to the risk of high temperature burns. At the same time, regular maintenance is required after using the equipment. For more questions about the polystyrene melting machine, you can consult GREENMAX.
