Just to throw something else in here...

If you chuck them in the bin, they will never break down in land fill, is there anywhere that you could donate them to???
Friends or family?
I cleaned out all our old stuff and kept some of the old stuff for a camping/picnic setting - you may have friends that could do the same...

Sorry to be annoying, but i really hate the fact that we throw away perfectly good and useful items, just because we dont need them anymore or they are old iykwim

If they are broken, however go for it...
