Our model estimates the total hidden costs of Styrofoam (for the current production output of 3 million tons) at $7 billion annually. This represents an estimated hidden cost equivalent to 1.2 cents per Styrofoam cup produced .
How do you manufacture polystyrene?
Polystyrene is made in a process known as suspension polymerization . After styrene is produced by combining ethylene and benzene, it is merged with water and a mucilaginous substance to form droplets of polystyrene.
How much is recycled polystyrene worth?
However, EPS is highly recyclable and very much in demand; it has a value of about $350/ton .
Which country produces the most polystyrene?

Is polystyrene bad for the environment?
Styrofoam is not only a dangerous air pollutant but also poses a great threat to humans, the environment, and animals. The worst part is that Styrofoam takes over 500 years to decompose and in the process, it leaches harmful chemicals into the environment.

How do you dispose of polystyrene?
Before starting the recycling process, check with your local government to see if it has a curbside recycling program that explicitly recycles EPS foam. Unfortunately, not all towns have these kinds of programs, so you might need to find a recycling center where you can drop off your foam recyclables.
Where is polystyrene banned?

What are the disadvantages of polystyrene?
- Brittle, poor chemical resistance especially to organics.
- Susceptible to UV degradation.
- Flammable.
Is styrofoam or plastic cheaper?
Cost. If price is your main concern, plastic is the less costly option. It is lighter, which makes manufacturing and shipping less expensive. Styrofoam is a little more expensive to purchase , but it does double as a hot and cold drink cup, so it may be more cost-effective in the end, depending on your intended use.
