Abstract

For this study, the CO2 concentrations of three municipal solid waste incinerators were measured for a year by using the continuous measurement method, and then the collected monthly, quarterly, and half-yearly samples were compared against the average yearly samples, in order to find out the appropriate CO2 concentration sampling cycle. The results of the Kruskal–Wallis test showed that the averages of the monthly, quarterly, half-yearly, and yearly samples of the three municipal solid waste incinerators were different. Then, the monthly, quarterly, and half-yearly samples were compared to the yearly samples in a post-hoc test. In conclusion, the monthly CO2 concentrations of incinerator C were different from its yearly samples, and for incinerators A and B, the averages of all of the monthly, quarterly, and half-yearly samples were different from the average of their respective yearly samples. Therefore, the results of this study indicate that monthly samples of the CO2 concentration of municipal solid waste incinerators, which can be secured in the largest volume and which include the most details, should be secured to investigate the appropriate CO2 sampling cycle.
