Waste electrical and electronic equipment, i.e. e-waste, is a great concern among researchers and policymakers, due to its potential as a source of serious environmental pollution. In order to understand processes and issues by informal e-waste processing in the Philippines, informal smelting process for gold was clarified from the field survey at several smelters. Metal recovery tests were conducted at one site with actual e-waste samples. Three types of e-wastes were tested: computer memory boards, boards for hard disk drives, and boards for video cards. Among three e-waste samples tested, memory boards contained the highest amount of gold. Since the gold content of non-segregated e-waste is not high, pre-processing is essential for gold extraction to raise cost-effectiveness. With regard to health and environmental effect, many issues were found including protective equipment for workers.
