Abstract

The Iron and steel industry is one of the most energy-intensive industries. This paper presented CO2 intensity and energy intensity of Iron and Steel production in Thailand. The technical data were obtained from 5 semi-finished steel production plants which represent 66.07% of the total semi-finished steel production capacity and 26 finished steel production plants which represent 63.77% of the total finished steel production capacity during the year 2004-2010. The scope of GHGs emission calculation was gate-to-gate boundary. The amount of
greenhouse gas emission was calculated by following the 2006 Intergovernmental Panel on Climate Change (IPCC) guidelines for national greenhouse gas inventory. The results showed that CO2 intensity of semi-finished steel product was 0.44 tCO2eq/t product whilst the CO2
intensity of finished steel product was 0.17 tCO2eq/t product. The uncertainty values ranged from 4.09% to 8.66%. Energy intensities of semi-finished steel product and finished steel product were 1.98 and 1.63 GJ/t product, respectively. The electricity consumption was a major source of greenhouse gas emission contributing 58.42%, followed by fuel combustion (33.17%) and chemical reaction (8.41%).
