Urban metabolism study highlights the consumption of the input resources, the process within the system together from the source, use phase and recycling of wastes. The aim of the study was to assess urban metabolism in three cities in Malaysia; Kuala Lumpur, Ampang Jaya and Selayang by using Material Flow Analysis (MFA). Primary data through questionnaires and secondary data from government agencies and public service providers were obtained and analysed. The data that was analysed included electricity inputs, water inputs, rice, eggs and sugar inputs, carbon dioxide outputs, wastewater outputs and solid waste outputs. National data were downscaled to regional data where deemed necessary. The study found that electricity use are not significantly differed with the use of home electrical appliances alike. On the other hand, water use and food consumption significantly differed among the three cities as the number of households and city living standard varies. The electrical consumption of 0.188 koe/cap/day in Klang Valley contributed to carbon dioxide of 0.455 kg/cap/day while 95.32% of water consumption became wastewater. Consumption of 0.38 kg/cap/day of rice, eggs and sugar contributed in the production of 4.5 kg/cap/day of solid wastes. The urban metabolism approach provides information on urban management such as material cycling, energy efficiency and waste management and may also assist in decision making for future urban development planning as well as providing an informed and rapid assessment on the performance of urban area.
