Did u take it to an apple shop to see how much to repair? I spilled water over my wife's MacBook Pro (made me v popular). It went "fizz" then died. Made an appointment with an Apple Genius, they replaced the onboard PSU and it's been good as new since (this was maybe 3-4 years ago).
If u are sure u don't want it, it's more valuable fixed than broken.
Alternatively, there may be companies near you that recycle electronics, they may pay you for it.
If you have any functional accessories (power lead, etc) they could also be sold on eBay, etc.
