摘要

Ghana's increasing challenges of waste management and clean cooking fuel necessitate sustainable solutions. Small-scale biogas digesters present a viable option for addressing these issues by converting organic waste into biogas for domestic energy needs and biofertilisers for agriculture. This study investigates the adoption of small-scale biogas digesters in Ghana, focusing on design preferences, operational challenges, and stakeholder roles. Using a mixed-methods approach, data were collected from installers, users, and institutions through structured interviews and surveys across selected regions. Findings revealed that fixed-dome digesters dominate installations due to their durability, while prefabricated digesters offer cost advantages and limited skilled labour requirements but lack widespread adoption. Barriers to adoption include high initial costs, inadequate technical expertise, lack of standardised designs, and limited public awareness. Gender disparities were evident, with women underrepresented in technical roles, highlighting the need for targeted inclusion strategies. Despite these challenges, the study identified significant potential for digesters to meet up to 48% of household cooking fuel needs and 6166 tons of daily organic waste management. To enhance adoption, the study recommends implementing targeted financial incentives such as low-interest loans, subsidies, and tax breaks for digester installations. Public awareness campaigns highlighting the economic and environmental benefits of biogas are essential for addressing misconceptions and increasing user acceptance. Standardised training programmes and certification systems for installers. Real-time monitoring systems should be integrated into digester designs to improve operational efficiency and troubleshooting. Gender-inclusive policies and tailored technical training programs for women are critical to fostering equitable participation in biogas technology. These actionable insights provide a roadmap for integrating biogas technology into Ghana’s sustainable development agenda.
