Compost vs. Garbage Disposal?

I just found out that my trash service picks up compost materials. But most of the stuff I would compost otherwise, I've got a garbage disposal to get rid of. Which is better for the environment for me to do?

LIsts!

I need help fleshing out a couple lists w/ ideas from your noggins.

( List 1 - Halloween Ideas )

( List 2 - Union/Labor/Solidarity/Old Timey songs )

If you've got suggestions for either list, please comment.

ETA: Holy crap union songs!
