Social Marketing in the Industrial Sector

The Iowa Dept. of Natural Resources has a program utilizing field reps to market various programs. The programs include:
1) matching one company's waste as a raw material for another company
2) conducting large industry assessments on everything from water/energy use to waste management to purchasing
3) promoting a waste reduction and recycling finanical assistance program Am working on the angle of social marketing in the industrial sector.
Most information I have seen on social marketing focuses on health and of course environmental issues. However, the environmental arena seems to focus most on individual / household behaviors. Any information or sources you could provide me on social marketing in the industrial sector would be very much appreciated. I hope I am on the right track with my initial efforts.

Thanks
