Hi P2 Techsters!
Is anyone aware of any innovative approaches for reusing spent toner?
We're working with a company who has an aggressive cartridge recycling system
and wants to find the most environmentally-friendly method for getting rid of
the unreusable toner. It's not hazardous and can be landfilled, and
currently they are paying to have it blended with fuel for heating.
They are considering an offer by a NC brick-making company to use the spent
toner. The brick-maker mixes the spent toner with water to create a slurry
which is added to the brick solution. Reportedly, all of the toner
(polystyrene, iron oxide, and contaminated paper fibers) are baked off in the
kilning process. It sounds good to the company since the brick-maker will
take it. However, they wonder about the advantage to the brick-maker since
the toner evidently doesn't add any mass to the bricks. In addition, there
are handling difficulties and presumably increased air emission
Does anyone have any further insight on this methodology and its potential
benefits and drawbacks? NC folks, could the company be getting any kind of
subsidy or other financial consideration for taking the spent toner like in
the case of fly ash?
