How do I properly dispose my water cooler, ironing board and other hard plastic trash?

Question:Shoud I just throw these items into my trash can? I'm thinking the ironing board can go in there, but what about my broken water cooler? That thing's pretty heavy.

Answers:
Give any metal to the scrapman take a sledge hammer to the rest and break it up in little peices and throw it in a garbage can.
