I forget who exactly but check out Xmas light recycling thread or videos. There was a video posted and basically the lights and wire etc was shredded and spread out on a water table that vibrated. It's a pretty simple process that once perfected seems profitable.
Ummm, check it out. I'm not going to search around for it or post a link cuz I've already viewed it. It's out there, somewhere.
I hate computers, but I love breakin em!
