Nigerian officials on Wednesday announced plans to charge duties on old computers imported for spare parts because much of the excess material is later dumped and causes toxic waste, Reuters reports. The strong local culture in Nigeria seeks affordable computers and habitually patches older systems up to keep them working for many years. Currently, importers at no cost can ship in old computers, which are gutted for spare parts. The unwanted pieces, however, are simply thrown away, causing waste disposal issues. According to Reuters, developed countries have increasingly turned to regulating the disposal of unwanted electronic appliances, but in Nigeria and other developing countries waste management is haphazard, with roadside trash burnings common throughout Nigerian cities, as well as the growth of massive dumps sites in densely populated areas. Nigerian officials note that "[old computers] will be banned completely later, but it has to be a gradual process to avoid our country turning into a dumping ground for scrap," adding that the tariffs "became necessary because [the computer parts] are found to have toxic waste that causes cancer and other hazards to health" (Reuters South Africa, 2/7/08).
