Postage-paid cartridge recycling envelopes are included with most HP Instant Ink shipments*. To maximize environmental benefits, wait until you have three to eight empty cartridges, fill the envelope, and then send them back together.
If you do not have a postage-paid recycling envelope, either wait for the next ink shipment or order an extra envelope from your Instant Ink account page.
*Cartridge recycling is not available in Italy or Portugal. Follow local regulations to dispose of cartridges responsibly.
HI...thanks for the answer to my question. Your reply was very detailed and helpful to those who don't know about the recycle methods for Instant Ink. I learned from another source that the envelope that is included with the ink supply is postage paid by the receiver in the USA. That was really my question.
