The Arkansas Material Exchange is for secondary materials from Arkansas businesses, such as byproducts of manufacturing processes.  The materials are posted free of charge and the site is managed by ADEQ’s Solid Waste Division’s Recycling and Market Development Branch.  Unfortunately, this site is buried in ADEQ’s web pages and is not getting much participation or generating any data so far.  The Solid Waste Division is planning to join the RENEW site on The Zero Waste Network’s web site.  That site includes Oklahoma and Texas, too.  New Mexico may be joining soon, also.
