Abstract:
There is the inevitable increase in domestic and industrial waste with the increase in world population. The end products from the waste treatment plants are mounting and we are now faced with the inevitable end of one day being surrounded by our waste. Therefore it is crucial for us to find possible applications or uses for this waste. A social perception study was conducted by our research team to obtain acceptable uses of sewage sludge and treated waste water. In this research the possible application of sewage sludge as fertilizer for non –food crop such as the grass in the golf course was studied. The results show that using sewage sludge as fertilizer in golf courses may be an amenable application; as test conducted on soil post sludge application showed no significant threat in the increase of heavy metals and pathogens in soil.
