I just created a bioplastics group on linkedin to discuss related topics. I invite you to join it:

Linkedin is a social network directed to professionals, to promote networking and discussions. You can check my profile, but if you are new to linkedin, I recommend you have a look around. For those of you that already know it, just say that it has become much more proactive. You can now use different tools to encourage professionals with similar interests to meet, tools like groups, questions or notifications of events.

I have asked a few open questions, which anyone can answer. The great advantage to me is that with linkedin I can check what type of background the person answering has, which can be any really. Here you have links to my questions, although the 3 are closed now!

Have fun!
