Here's my try on the logo: The earth is sheltered by a shell like recycle symbol, the space between the shell also forms an 'S' mark, the shell also looks like leaves as for environment. Can be revised to your likings.

Original sketch for Sycle.

now this time for a logo of recycling company I try to make some thing new, the concepts we use of errows are old and most of the companies use them.
now I show the recycling process in a different manner then older logos.
the recycling errow show the process of recycling and the green material is the product which we found after the recycling process and both errow and leaves are around the globe.
PERSONALY I Like this logo very much.
@ View full plz.
Thanks.
