This paper applied a new methodology to estimate the generation rate of waste refrigerator using Population Balance Model as well as assigning Weibull Distribution Function as probability distribution function (PDF) of lifespan. In order to determine the generation rate of waste refrigerator, it is necessary to estimate yearly sales quantity of new refrigerator and lifespan PDF of refrigerator. The average lifespan of refrigerator is determined to be 16.8 years as a result of averaging the lifespans of 4,682 waste refrigerators. We also developed a methodology to calibrate the PDF of lifespan of waste refrigerator. The generation rate of waste refrigerator in 2014 is estimated to be 1,822,633 decreasing sharply with time. The new methodology developed here can be applied to estimate the generation rates of other e-wastes.
