Urban metabolism studies h ighlight the consumption of input ISSN 1927 - 9566 resources, the process within the system together from the source, use phase Vol. 5 No. 2 , pp. 45 - 5 3 and recycling of wastes. The aim of this study was to assess urban metabolism in (2016) three cities in Malaysia; Kuala Lumpur, Ampang Jaya and Selayang by using Material Flow Analysis (MFA). The data that was analysed included electricity inputs, water inputs, food (rice, eggs and sugar) inputs, carbon dioxide outputs, wastewater outputs and solid waste outputs. The national data were down - scaled to prov ide regional data where deemed necessary. The electricity consump tion 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, egg s and sugar’ contributed in the production of 4.5 kg/cap/day of solid wastes. The urban metabolism approach provides information on urban management at city level such as material cycling, energy efficiency and waste management and may also assist in decis ion making for future urban development planning as well as providing an informed and rapid assessment on the environmental performance of urban area.
