#1 Gets my vote (given the options presented)
#2 doesn't seem very serious
#3 too spaced out

Overall, I don't know that these logos accurately reflect the industry. It seems more web 2.0 than a serious recycling company. Also, the font of Pink just does not come off as professional.
I would highly suggest looking at other companies and getting a feel for the industry standard. It's one thing to stand out, but there's limits. I wouldn't accept any of these logos if I were them.
The design may look "cool", but it seems more happy/fun than a serious business. I wouldn't hire them w/ those logos.
