EPS (expanded Polystyrene foam) is an attractive material as a kind of packaging material. So it was widely used in our life. While another question comes out. There is a challenge to recycle it. In a short, its low density results in a large cost to gather it. As we all know, Expanded Polystyrene foam is over 95 percent air. When contained in bulky, hard plastic shapes, can become remarkably expensive to transport.
EPS is a very recyclable and desirable material. However, collection of EPS can be a major challenge because of its lightness. Now some companies have been successful in recycling EPS. Because they create a collection system in which the EPS is shipped over short distances to a facility where material can be aggregated and either compressed.
When the material recycled is compressed, it is more cost and effective to transfer from one place to another over longer distances to reach the hands of user. In fact, whether density it’s not the only issue concerned by users. Due to the material will be used to reuse new products, so it must be clean and no impurities before being compressed. It matters product quality issues for future its end users. This challenge is the reason most food foam packaging is not accepted for recycling.
