The study of experimental study conducted by fermenting compost from municipal waste, vegetable waste, Yasothon Province Thailand. by the catalyst using are bio-fermented and catalyst microorganisms from the Department of land development(PD1). The dilution rate are1:200 1:100 and 1:50 In order to reduce the period of composting from municipal waste Yasothon Province Thailand. The three types of experiments. Type A Solid Waste Division 6 pile by 3 first put accelerator biologically fermented, 3 division final put PD1. By dilution rate 1:200. Type B Solid Waste Division 6 pile by 3 first put accelerator biologically fermented 3 division final put PD1. By dilution rate 1:100. Type C Solid Waste Division 9 pile by 3 first put accelerator biologically fermented, 3 division another put PD1. By dilution rate 1:50, 3 division final put only water. Repeat 3 times, Humidity controlled by reverse the fertilizer and humidity measurement at 16.30 every day.
Result showed that the started temperature and end point temperature of the compost pile all are near Equivalent, But different duration the end of the fermentation process. The accelerators used the degradation is biologically fermented at dilution rate 1:50 Fermentation period average 29 days. Which end of the fermentation process of this study found that degradation is compost faster than plain water for 7 days (36 days). In conclusion, the kind catalyst that brought composting is an important factor that contributed to the compost has decomposed faster, and there are also other factors that contributed to the compost to an end as soon as the type and composition. the compost material is a mixture of compost as well as keeping the moisture level of the compost pile, which controls the level of the potassium from this study showed that all compost pile volume. nitrogen, phosphorus, potassium, according to the standards of the Department of Agriculture in 2548.
