The electronic waste (e-waste) stream is growing rapidly due to everchanging trends and innovations in technology, increasing need of electronic devices for the modern human, shorter life spans of new products, and early obsolescence of former technologies such as cathode ray tubes (CRT). With massive disposal done over a short period of time and inadequate laws governing e-waste management in Indonesia, a means for formal e-waste management is needed to minimize the health and environmental hazards caused by irresponsible handling by informal sectors. A case study of waste CRT TVs and monitors, and washing machines is done to represent Bandung City. An e-waste generation survey is conducted to represent the domestic (200 households) and nondomestic sector (75 units consisting of schools, offices and laundromats) to obtain data and later project future e-waste generation. Results of the projection show an average waste load of about 84.000 CRTs per year (which is predicted to have diminished by the next 10 years) and 48.000 washing machines per year, weighing an estimated total of 4.900 tons per year. The main materials recovered from CRT TVs and monitors are glass, meanwhile from washing machines are metals. The recycling facility designed on TPPAS Legok Nangka site will consist of, first, manual dismantling, then CRT cutter, followed by further metals, plastics, glass and cables processing. The products will be in the form of cullets or pellets of metals (ferrous and nonferrous), plastics, and glass, with a remaining residue sent to the nearby landfill zone, and whole components such as PCB and washing machine engines which will be sent to third party recyclers. With a capacity of 19,6 TPD e-waste load, the amount of recovered materials, according to the design, will reach 17,8 TPD, giving a total recovery rate of 91% and a material purity of 98%.
