Hydrogen production based on total VS fed to the digester
showed a significant 2-factor interaction between mixing ratio
and organic loading (P< 0.001). The production increased linearly
(P< 0.001) with increasing organic loading, and was greater at high
organic loading (OL40 and OL60) than low organic loading
(P< 0.05) for all M:WM ratios except M:WM 70:30 and 0:100
(P> 0.05
