From the results of the study found that LHV 20 days of third pile is Biodrying, Control and Open dump in layers upper, middle and lower respectively. The LHV of Biodrying is higher than Control and Open dump. Particularly, the LHV upper of Control and Open dump are Low, because both of 2 piles do not biodegradation by micro-organisms in waste piles due to lack air to enter the system. There are just the Open dump period 20 days LHV higher than 5,000 kcal/kg (show in Table 4.7 and Figure 4.11). For the Control system period 20 days LHV maximum 3,721 kcal/kg in upper layer. (Show in Table 4.7 and Figure 4.11)
