What useful products can be made from waste expanded polystyrene (EPS)?

This white foam-like plastic is used in packaging applications like the molded chunks around televisions and packing peanuts. It prevents products from being broken in transit and is the lightest packaging material available.

After use, it breaks easily into tiny pieces (often shaped like balls) and litters the environment, often being mistaken for food by wildlife.

Waste expanded polystyrene is available in varying amounts in most communities. We have heard of it being used for insulation; and for air pollution control (in place of activated carbon), though this would need further research. We are open to creative ideas and appropriate technologies for low-income countries.
