At present resource extraction techniques remain the priority among Waste Electrical and Electronic Equipment (WEEE) recyclers. As a result, fully functional components are often destroyed together with other non–recyclable materials. Yet, another process stream is evolving, namely repurposing of specific types of WEEE for alternative uses after minimal modification. This paper presents a Maximum Power Point Tracking (MPPT) buck converter suitable for cell phone charging in remote areas of the developing world utilising discarded computer power supplies.
