RE: Spent Toner -Reply



Tom-

If the quantity is sufficient . .  TONS.   I can only think of larger
manufacturing operations like tires and asphalt batch plants that would
be interested.  My experience with the toner cartridge industry is they
do not generate enough, have the room, or want to store enough of it to
make this worthwhile.  

Check for small manufacturers who would use it in their feedstock. 
What about adding to  compost in a slurry?

The stuff is really messy and inexpensive.  I don't forsee a big market
for recycling it.  What we need to see happen is copier and cartridge 
technology improve the way toner is used.  Reducing the excess that is
dumped at the copier, being able to restore the spent toner just like we
can antifreeze. 

good luck,

Tom,

I doubt the brick maker is not getting any benefit from this.  Are they
being paid to take the toner, if so, how much ?  Toner is messy to
handle
and unless they were being paid a lot to take it, no one would bother. 
Then
there is the issue of the generator having to pay to get rid of it. Since
its not hazardous, why would they be motivated to pay someone a high
fee to
take it ?  If the brick maker is paying for it, then there most likely is a
beneficial reason.

My guess is that the toner creates a darker blacker brick.  Perhaps it
speckles the surface and makes the brick look like its covered with soot.
Used brick sells for a premium over raw red brick and this may be the
benefit created.  If so, the brick maker may see this as an economic
advantage.  Since this is all a guess, why don't you ask them ?

Just my thoughts,
