A Circular Economy Approach to Addressing Waste Management Challenges in Tamale’s Waste Management System

Abstract

Ghana Tamale’s current waste management system is overwhelmed by the growing waste crisis, necessitating the exploration of Waste-to-Energy technologies (WtE) as an innovative solution. This study explores challenges and opportunities for integrating WtE technologies into Tamale’s existing waste management system. Qualitative research identified policy hurdles, financial constraints, social concerns, and institutional weaknesses as key barriers. Conversely, stakeholder collaboration, public education, and capacity building emerged as some success factors. A proposed implementation plan emphasizes feasibility studies, public engagement, public–private partnerships (PPPs), and technology selection based on waste composition. Additionally, a novel framework for WtE integration within a broader Integrated Solid Waste Management (ISWM) system is presented. This framework incorporates waste sorting, recycling, WtE alternatives, and responsible management of residuals. Validation by key stakeholders confirmed the framework’s potential to improve waste management in Tamale. By overcoming identified challenges and implementing the proposed framework, Tamale can achieve environmental sustainability, energy generation, and progress towards UN SDGs 7, 11, and 12. This research offers valuable insights for policymakers and paves the way for a cleaner and more sustainable future for Tamale, potentially serving as a model for other developing cities.
