Out of all the counties I know about that have a curbside recycling program, none of them will accept paperboard. It is the stuff that most food products are packaged in... non corregated cardboard. It seems like if they can recycle paper and cardboard, then why not paperboard?? They also do not accept paper like junk mail or printer paper. Why??
Someone who actually knows what they are talking about, please... don't guess.
