Source separation and recycling potential of municipal solid waste in Ghana
Purpose – The purpose of this paper is to assess the waste characteristics and separation efficiency of source separation of household waste in low- and middle-income communities in Kumasi Metropolis, Ghana. Design/methodology/approach – A sample of 60 households participated in the household survey, education on source separation and pilot source separation exercise. The solid waste was sorted into six fractions and three recycling categories (biodegradable; paper and plastic; residue). Findings – The mean generation rate of solid waste was 0.52±0.26 kg/per capita/day for the low-income community and 0.65±0.27 kg/per capita/day for the middle-income community. The waste fractions in the communities (low, middle income) were biodegradable organics (59.15, 65.68 per cent), plastics (11.01, 10.68 per cent), papers (3.15, 4.51 per cent), glass (0.89, 2.57 per cent), metals (0.96, 4.63 per cent) and miscellaneous (24.84, 11.93 per cent), respectively. The separation efficiency for organic category was 70 per cent, inorganic and residue was over 69 per cent and the paper and plastics was over 60 per cent. Research limitations/implications – The study suggests that the success of source separation programme hinges on education and economic incentives. It was noted that the sample size could be increased to enhance the accuracy of the data for prediction purpose. Practical implications – The findings showed there is potential for recycling through source separation programme in low-and middle-income communities. Public education and economic incentives are necessary for successful source separation programme. Originality/value – The paper provides insight into source separation to contribute to better understanding of how city authorities in developing countries could take advantage of economic incentives to scale-up recycling.
