Municipal solid waste source separation at the household level has been endorsed as the way forward by all stakeholders in the waste management sector in Ghana. The study using waste stream analyses and laboratory investigations assesses the feasibility of this intervention in the Accra Metropolitan Area which has been divided into three income zones. The mean waste percentage composition was dominated by 75% organic and 8% plastic waste. Mean values for total carbon, available carbon, nitrogen, C/N and moisture values were 90.2, 45.1, 1.83, 27.6 and 51.7% respectively. The low income high density zone recorded higher separation levels followed by high income low density and middle income low density zones. The study recommends that the policies to guide its successful implementation should be supported by public education and the right infrastructure. Copyright © 2011 Inderscience Enterprises Ltd.

Purpose: The purpose of this paper is to verify claims that water supplied by operators of tanker trucks in Cape Coast does not meet quality standards recommended for human consumption, and to investigate the sources of any contamination. Design/methodology/approach: Samples were collected from a water hydrant from which tanker operators draw water from the Ghana Water Company Limited distribution system in Cape Coast and a number of tankers sampled at random. Additional samples were taken from the premises of a patron of the tanker service and a regular customer of the Ghana Water Company Limited. All samples were subjected to physico-chemical and bacteriological analyses and the results compared with the World Health Organization's guidelines for drinking water. Findings: It was found out that water supplied by the tanker operators indeed failed to meet the World Health Organization's guidelines for some quality parameters as alleged by patrons of the service. The tanker-supplied water was found to contain high levels of Escherichia coli, colour, turbidity and total iron. This was found to arise from the management of the water hydrant and the tankers by the Ghana Water Company Limited and the tanker operators respectively. Originality/value: The study provides a basis for the set of actions that must be taken to safeguard public health and consumer confidence in drinking water supply using tankers as an emerging alternative to conventional water supply in urban centres of the developing world. © Emerald Group Publishing Limited.

This article examines activities of scavengers in the waste management sector in the Greater Accra Region of Ghana. Data on socioeconomic activities and demographic characteristics of scavengers were obtained using a questionnaire survey. The questionnaire included basic information such as gender, age, level of education, residential status, number of working hours, alternative occupation, income level, type of material recovered, source of the material, processing of material, peak seasons for each material and uses of recovered material. Scavenging in Greater Accra is carried out mainly at landfill sites and commercial areas of the city, and is male dominated. Materials recovered include plastics and metals such as iron, copper and aluminium. On the average, scavengers earn between US $7 and US $17 per day depending on items recovered and market trends. Their average daily earnings surpass the US $1 a day target for poverty reduction under the Millennium Development Goals. The activities of scavengers contribute to waste recovery and recycling through their sorting and cleaning activities. Local authorities in Ghana could improve waste recycling and resource utilization if they recognize scavengers of waste materials as important stakeholders in the waste management sector. © 2012 Elsevier Ltd.
