Description

The rapid adoption of solar photovoltaic (PV) systems in developing countries is a critical driver of the global transition to renewable energy. However, the growing volume of end-of-life PV waste presents significant environmental and resource challenges, especially in regions with inadequate waste management infrastructure. This study focuses on developing a cost-effective circular economy model tailored to the management of PV waste in developing nations, with Kenya as a case study.

Key components of the proposed model include an assessment of existing waste management practices, an evaluation of current recycling technologies for crystalline silicon PV modules, and recommendations for policy and regulatory frameworks to enhance sustainability. Emphasis is placed on resource recovery and recycling to reclaim critical materials such as silicon and silver, aligning with Sustainable Development Goals (SDG) 7, 12, and 13.

The findings suggest that a circular economy approach can mitigate environmental hazards, promote economic growth through recycling industries, and improve resource efficiency. This model provides actionable insights into integrating end-of-life management with renewable energy expansion, offering a scalable solution for other developing regions.
