L-AD of taro skin, taro flesh, papaya, and sweet potato obtained
CH4 yields from 345 to 384 L kg1 VS, which were significantly
(p < 0.05) higher than those of albizia leaves (161 L kg1 VS) and
albizia chips (113 L kg1 VS) (Fig. 1a). Compared to lignocellulosic
biomass, food wastes usually have high amounts of organic solubles,
thus can achieve higher methane (CH4) yields
