Rather than ship your empty cartridges back to our warehouse, we suggest that you find a local recycling facility for proper disposal. It's not only better for the environment to keep them local, we've found it's more convenient for our customers. Most major office supply retailers will accept old or recycled cartridges, or direct you towards a resource that will accept them. To find the closest recycling facility in your area, visit Earth911.com. Just search by material type (ink or toner) and your zipcode.
