HP allows the return of cartridges for recycling at no cost, but the customer does not receive any monetary credit for recycling. If the cartridge is detective, it should be returned where it was purchased to determine if it is eligible for a refund.
The materials necessary to return cartridges are available at retail locations or through HP by request on its website. Postage materials can also be printed through HP's website. Once the cartridge is empty and the paid shipping materials are obtained, seal the cartridge and either mail it or arrange for a pallet pickup. Cartridges can also be dropped off at HP Authorized Retail Collection Locations located across the United States. Additionally, all LaserJet cartridges include a postage-paid label in the packaging.
Recycling through the HP Planet Partners program keeps hundreds of millions of empty cartridges out of landfills and contributes to a cleaner environment. The program began in 1991, and since then, over 500 million cartridges have been returned to HP for recycling. HP uses a "closed loop" recycling process to ensure that recycled materials are used as raw material to produce new cartridges. Most HP ink cartridges are made of up to 70 percent of recycled material.
