Hospitals generate hazardous wastes that contain disinfectants and other harmful chemicals, and also pathogenic microorganisms.
Such wastes also require careful treatment and disposal.
The use of incinerators is crucial to disposal of hospital waste.
Irreparable computers and other electronic goods are known as electronic wastes (e-wastes).
E-wastes are buried in landfills or incinerated.
Over half of the e-wastes generated in the developed world are exported to developing countries, mainly to China, India and Pakistan, where metals like copper, iron, silicon, nickel and gold are recovered during the recycling process.
Unlike developed countries, which have specifically built facilities for recycling of e-wastes, recycling in developing countries often involves manual participation thus exposing workers to toxic substances present in e-wastes.
Eventually recycling is the only solution for the treatment of e-wastes provided it is carried out in an environment-friendly manner.
