Blandin Paper Co. in northern Minnesota is interested in recycling sludge into
its extensive forest land holdings, combined with site specific fertilization
additives to improve forest growth and solve a sludge landfilling problem.  We
generate 165 tons of sludge per day.  This sludge is approximately 35% solids
and is composed of about 90% primary and 10% secondary solids.  Of the total
solids generated about 99% comes from a pressurized groundwood pulping (not a
Kraft pulp mill) process wastewater, with the remaining 1% coming from municipal
domestic wastewater.  The papermill wastewater is approximately 35% non-volatile
(clays) and 65% volatile (wood fiber).

Any information on solving this problem or contacts with others who are
operationally involved in doing such an operation would be appreciated.
