People who upgrade their computers have been urged to donate their used hardware to a recycling scheme launched yesterday. It is hoped that more than 400 used computers will be collected in just a month. They are to be donated to welfare agencies and to any students with financial difficulties. The computer recycling project is co-organised by RTHK Radio 2 and the City Junior Chamber. 'People are upgrading their computers more frequently, but old hardware may have been left untouched at home or even being thrown away.' said project chairman Thomas Kan Ming, adding: 'We think it will be perfect if we can give them to suitable user.' Mr Kan was looking out for all kinds of second-hand computer hardware, including monitors, printers, hard disks, keyboards and scanners. Social services groups or individuals are welcome to pick up the donated items, he added, provided they can present a letter stating valid reasons for wanting one of the computers. Interested parties who either want to donate or get computers can call 2538 9909 or fax 2798 5600. The Internet address is: http://www.hkjc.org/city/ recycle .
