The CH4 content of food wastes (70–80%) was much higher than
those of albiza leaves and albizia chips (60–70%) at steady state.
During L-AD of albizia leaves and albizia chips, CH4 contents
increased to 60–70% in 10 days, and then maintained at that level
with slight variations. During L-AD of taro skin, taro flesh, papaya,
and sweet potato, CH4 contents reached maximum levels (70–80%)
in a shorter time (8 days). After that, CH4 contents maintained at
the maximum levels until the termination of L-AD
