Transitioning wastewater treatment plants towards resource recovery: Challenges and opportunities in Zvishavane, Zimbabwe

ABSTRACT

Developing countries still lag in transitioning wastewater treatment plants towards resource recovery. This study assessed the challenges hindering and opportunities enabling the implementation of resource recovery from municipal wastewater treatment in Zvishavane town, Zimbabwe using the descriptive case study research design to collect data from selected key informant interviewees. Findings highlighted that resource recovery from Zvishavane’s Mabula wastewater treatment plant was at a nascent but dormant stage. Policy, economic, technological factors and lack of expertise were identified as limiting the transition towards resource recovery in Zvishavane. On the other hand, findings indicated that several enabling factors could enable the transition of the Mabula wastewater treatment plant into a resource recovery facility. These included the presence of entrepreneurs working in the resource recovery sector, university-utility collaboration and a vast raw material base. A stakeholder interaction model was developed to create pathways towards resource recovery in Zvishavane.
