Abstract
In Vietnam, the ceramic industry is one of the construction material production sectors that has large emission of CO2 - the major greenhouse gas, since it consumes a large amount of fossil fuels. This research aims at preliminarily estimating the CO2 emission factors for two major kiln technologies currently used in ceramic production sector in Vietnam, namely the traditional kiln and tunnel kiln. For this purpose, field measurements of CO2 concentration in stack flue gases of two ceramic factories in Hanoi City, Vietnam were conducted. The results of data analysis have shown that the traditional kiln has higher CO2 emission factors compared to those of tunnel kiln. The low energy efficiency and high energy consumption of the traditional kiln are the major causes for its higher CO2 emission factors.
