Leaving from DAAP blue box at noon on Friday.
We're visiting an e-waste recycling site in columbus

Here's the website.

Print ecology
Whole systems thinking, includes facts such as:
The most recent EPA data show that pulping and papermaking stands second only to oil refining as a producer of nitrogen and sulfur oxides. Printers, meanwhile, take the silver behind big steel's gold standard for carbon-monoxide emissions. Armed with these two facts at your next client meeting, maybe it won't be so hard to get buy-in after all.
EPA's report that airborne emissions account for 99% of the printing industry's toxic releases easily gives atmospheric issues precedence as the foremost print-ecology consideration. Unfortunately, users in a small to medium office setting have relatively few options for safeguarding indoor air quality beyond providing adequate and, if possible, separate ventilation for conventional office printers.
However, one choice stands out far above any other. Originally developed by Tektronix in the early 1990s, Xerox's line of Phaser solid-ink color printers are free of solvents or hazardous chemicals, emit no odors or fumes and generate miniscule amounts of solid waste, unlike typical color lasers. Phasers start at $1,000. Xerox also operates a FreeColorPrinters program, which hinges on participants agreeing to a sole source of ink and minimum monthly usage levels.
And also neat info on inks and papers

Dry Toner or Inkjet?
From a website on green printing:
Environmental issues have become key initiatives for print manufacturers, with increasing demand for eco-friendly technologies not only from environmental groups but also progressively more government mandates. Reducing Volatile Organic Compound (VOC) emissions to meet new environmental standards has become a printing industry requirement. Electrophotography's dry toner-based systems do not contain solvents, volatile substances or low molecular weight components, making them far superior to solvent- based inkjet and liquid toner—both with respect to VOC emissions and paper recyclability.
Inkjet technology sees UV inks as a solution for both reducing VOC emissions and addressing the evaporation issues when the ink is in the printhead to prevent nozzle clogging. However, UV light increases the energy consumption during printing, and the reactive type of chemicals used in these inks create safety concerns for operators and service engineers. Depending on the type of end-user application, special safety precautions have to be taken (e.g. in printing material for food applications).
UV inks continue to have issues with respect to the deinkability behavior. During the recycling process, repulping causes UV-curable and liquid toner inks to become ink specks—too large to be removed by flotation and too elastic to be removed by screening. When looking at pigmented inkjet inks, the flotation process doesn't work as well because the particles are too small to be removed. Dry toners, used for digital color printing processes, are widely accepted as deinkable. — Dr. Lode Deprez, VP Toner Development Group for Xeikon unit at Punch Graphix
