Styrofoam Recycling

What is Styrofoam?

Styrofoam is a form of polystyrene plastic which is known as EPS or Expanded Polystyrene Foam. Styrofoam has numerous good features such as light weight, low cost, high durability, high compressive strength and good chemical stability, thus it was widely used as packaging as well as insulation material in our daily life. Styrofoam recycling has benefit for both environment and economy.


Why styrofoam should be recycled?

However, Styrofoam contains benzene which is a carcinogenic chemical material harmful to human health. If the waste Styrofoam products are abandoned and eaten by animals, it may cause death to the animals. Styrofoam is also a material unable to be biodegraded; the approximate 30% of the Styrofoam is disposed in landfill around the world that are polluting the earth. Therefore, proper recycling to Styrofoam waste is very essential.


Currently the way to recycle Styrofoam is basically like below:
• Firstly use shredding machine to shred the Styrofoam scrap into small pieces.
• Secondly, use granulator to further shred the pieces into even small sizes, which is known as secondary shredding.
• Transfer the shredded pieces to a plastic extruder to be melted and reprocessed into new raw material. The new material can be made into various plastic product.
