Expanded polystyrene (Styrofoam) is a rigid and tough, closed-cell foam. It is usually white and made of pre-expanded polystyrene beads. The beads are heated by steam and expand 50 times before charged in a mold to become a formed piece, which contains 95 -98 % air and 2-5% polystyrene. It is a versatile, lightweight material that can be manufactured into a variety of products. Styrofoam offers a high-performance yet economical support for a wide variety of items—from sensitive electronics to appliances to pharmaceuticals—to be safely delivered to market. Manufacturers rely on Styrofoam packaging because it can prevent or minimize product damage during transit and it owns excellent insulation properties required for food and medical shipments.
Yet used Styrofoam will eventually become solid waste and have to be disposed. But here’s the good news: Styrofoam is recyclable. Although the availability of polystyrene recycling programs varies by community and can be limited, the Styrofoam industry uses average of 50 percent of the post consumer material collected in the manufacture of new Styrofoam transport packaging and loose fill packaging, which has reduced requirements for raw material resources, energy consumption has diverted material from landfills. Nowadays, more and more countries play an active role in Styrofoam recycling.



• Styrofoam is strong and lightweight
The way to recycle this plastic is to shred it and mix it with some chemical that you can buy in a hardware store or discount store. This chemical is acetone or finger nail polish remover. The finger nail polish remover that doesn’t contain acetone works to.What this does is to soften the plastic in to a paste or liquid, depending on how much chemical you use. You pour this into a mold and then wait for it to dry. When dry break the mold apart and voila. You have the part that you want.
