My inkjet printer stopped printing colors the other day. This was pretty inconvenient since we were trying to print boarding passes at the time, and nothing came out looking right. We bought a replacement cartridge (man, those are expensive!) to remedy the immediate problem, but I sat for a while staring at the old cartridge trying to figure out what to do with it.
Since it was an HP cartridge, I first went to the HP website. They have a recycling program for cartridges where you print out a postage-paid label, and send the cartridge in for recycling. Well, downcycling really. They shred the materials and put them in auto parts and other products.
I printed out the label, but immediately noticed that in order for my cartridge to be recycled, I have to mail it to Tennessee. From Seattle.
Let's think about this a moment: does that make sense? Won't we lose more in energy shipping it such distance back to HP than we gain out of the recycling process? We can figure this out.
Let's assume a semi-truck, 2800 cubic feet of space, drives straight to Tennessee, at the semi-truck average of 6 miles per gallon. My printer cartridge, individually packaged in a standard-size UPS box, is about 1 cubic foot, so let's say the truck has 2800 cartridges on it. Tennessee is 2500 miles from my home, so we're looking at 417 gallons of gas to get there. That's about .15 gallons of gas per cartridge to ship it back to HP. Best case.
On the flip side, it takes 2.5 quarts of oil to make a new printer cartridge. That's .42 gallons of gas. We don't know how much oil is conserved by the downcycling process, but given other similar recycling programs, let's put it at 40% efficiency. That means that recycling the cartridge will save .16 gallons of gas.
.15 gallons to ship it, .16 gallons saved in the recycling. It's not a very compelling argument for recycling. And that's even assuming that once the cartridge gets to Tennessee that it doesn't get shipped anywhere else to be processed.
I figured there must be some other options. And there are!
Refill until you are forced to recycle
Most printer cartridges can be re-used 4-7 times before they reach end-of-life and need to be recycled. Many companies, including Walgreens and Staples perform refill services. Lots to beware though. Some programs ship the refills out, so you should ask where it is going before you sign up.
Also, the quality of refilling is a bit dicey. Depending on the health of your used cartridge, it might not work as well as a new cartridge. Still, since refilling is significantly cheaper than buying a new cartridge (25-50 dollars cheaper per cartridge!) it's worth the risk of trying it.
Check with your local waste utility
Checking with King County Waste led me to a Kirkland-based business called Eco Cartridge. They are experts in refilling and re-manufactured cartridges and guarantee the quality of their work. They refill cartridges in-store in 10-15 minutes, and have a handy set of guidelines for keeping your cartridges working at their peak. They also work with local recycling agencies once the cartridges are no longer viable.
Finding a local resource like this is valuable since it keeps the miles down on your recycling effort.
Whatever you do, don't consider home refills
While home refill kits exist on the market, it's extremely difficult even for an expert to perform a cartridge refill with home equipment. One of the reasons for this is the compression needed in the cartridge for it to work properly. There's not a good way to replicate this at home. If you try it, your results could be rather...disturbing.
