52 per cent) are disposed of through landfill. Some waste areburnt behind the lecture rooms as well as the springs hostels. This is mainlycomposed of paper and plastics. The landfill site, developed in behind barrackshostel, is about 18m in size in circumference of which has been filled. Thissite is not fenced neither is it surrounded by any boundary wall. There is nocompacting of waste done at the site and the waste is left open. As a resultthe site is easily assessed by humans and animals (cows) that occasionallygraze in the field.
This poses a risk to both human and animal health. At timesbad odors come from the landfill especially during the rainy season. Thiscauses air pollution and discomfort to the residents at the barracks hostel.The waste is then burnt which also results to air pollution.During the ‘peak’ seasons whenthere are functions in the institution that attracts large populations such asgraduation ceremonies, the institution occasionally hires a truck from themunicipal council which transports wastes to Karindundu landfill in Karatinatown for disposal.
