Recycling toner cartridges
To reduce landfill waste, HP has adopted a recycling program for
empty toner cartridges. A postage-paid shipping label can be found
inside your HP LaserJet toner cartridge box. Up to 95 percent of each
returned toner cartridge is recycled for use as raw materials in the
manufacture of new cartridges and in other industries. To join this
recycling effort, follow the instructions provided in the new toner
cartridge box.
