Assessment of the Effectiveness of Bio-Digester Systems for Organic Waste Management

Patrick Aaniamenga Bowan, Adams Sumani

Abstract

This study evaluated the effectiveness of bio-digesters in managing organic waste in the Upper West Region of Ghana. The rising demand for sustainable waste management solutions and the environmental concerns associated with traditional methods necessitate an assessment of alternative technologies, such as biodigesters. The study employed a descriptive research design within a quantitative approach, collecting data from 268 respondents through questionnaires, interviews, and site observations. The results showed that 78.4% of respondents currently use biodigesters, with environmental cleanliness, lower waste-management costs, and odour control as the primary motivations for adoption. However, barriers such as high installation costs, lack of information, and technical support were significant deterrents for non-users. Operationally, most (53.3%) users rated the systems as good, although maintenance costs and technical breakdowns were noted as challenges. Environmentally, users reported improved sanitation, reduced open dumping, and beneficial use of bio-slurry, but concerns about groundwater contamination and effluent safety persist. The study concludes that while bio-digesters are effective in managing organic waste and offer environmental benefits, their success is dependent on technical reliability, cost accessibility, and user education. The study recommends the development and enforcement of standards for the design, installation, and operation of biodigesters to ensure safety and efficiency in the UWR and other developing areas with similar organic waste to that of the UWR.
