[GreenYes] Research Request: What motivates people to recycle?

[forwarded from a colleague; respond to list:]

I am looking for literature that quantitatively addresses the 
question, "What motivates people to recycle?"  

That is, to what extent can monetary incentives, convenience, 
environmental awareness, etc. be expected to trigger 
participation in recycling programs? I realize this question 
quickly becomes complex and that objective answers are 
ellusive.  I want to review the literature on how researchers 
have attempted to answer it and what kind of conclusions 
they've reached.
