Every remanufactured inkjet cartridge carries a 100% no-quibble guarantee from GreenTech. GreenTech remanufactured compatible inkjet cartridges are made in the U.K. to the same high standards as brand-name inkjet cartridges but at only a fraction of the cost. GreenTech runs an extensive cartridge collection service from schools, colleges, businesses, charities and home users who can all claim a cash credit for recycling each cartridge. The recycled inkjet cartridge is first inspected and thoroughly cleaned; it is then reconstructed, refilled with premium inks and electronically tested at GreenTech's manufacturing facility in the U.K. The process saves money (up to 70% compared to original cartridges), produces less waste (as much as 40% by weight) and is faster than making the toner cartridge from scratch. GreenTech have been collecting, recycling and remanufacturing inkjet and laser toner cartridges in the U.K. for over 8 years and estimate to have saved the equivalent of 200,000 Litres of oil or 31/2 football pitches worth of waste printer cartridges.
