Abstract— Industrial processes create variety of solid and liquid wastes; which may contain pollutants that have potential harm to humans, animals and the environment. Hence the challenge for disposal of waste for industries cannot be ignored. In these studies, a survey was conducted in the capital city of Botswana; Gaborone to investigate waste management practices for selected manufacturing companies. The findings indicate that companies disposed waste in different ways; 50% out-sourced waste collection services, while 8.3% disposed to waste treatment plants, 33.3% in sewage lines and the other 8.3% in the open flat land. Only 33.3% uses ponds to deal with its effluent and consequently recycle it. Of the companies surveyed, 33.3% of the companies indicated that they have hazardous wastes. Preliminary investigations on contaminates that find their way into the city’s sewage system shows that, Pb concentrations did not exceed maximum allowable concentrations of 5.0 mg/L, whereas Cd and Cr concentrations exceeded the maximum allowable concentration of 0.01 mg/l and 0.1 mg/l in irrigation water respectively.
