How to Get rid of polystyrene?

Answer 1

I expect you mean expanded polystyrene, which is also known as styrofoam. Polystyrene (the unexpanded type) can be recycled by many local authorities, however the expanded type usually isn't and ends up being put in black rubbish bags for collection by the dustmen. Thence it usually ends up in landfill or being burnt in a dust destructor or incinerator. This is one legal way of getting rid of it, but it's not ecologically satisfactory.

You can also burn it. It is very flammable, but it gives off poisonous fumes and contributes to pollution. It is also illegal in many civilised parts of the world to do that.

The best way of getting rid of it is to find a new use for it, keep it until you need to pack some china or glass, or a parcel enclosing something fragile. You could also use it in an art project, depending on its shape and size.
