Anaerobic co-digestion of dry fallen leaves, fruit/vegetable wastes and cow dung without an active inoculum – A biomethane potential study

Anaerobic digestion of fruit and vegetable wastes (FVW) is a sustainable energy production technology with low carbon footprint but lacks consistent, productive process performance. Hence, the anaerobic co-digestion (AcoD) FVW various lignocellulosic biomass has become necessary. This study investigated AcoD dry fallen leaves (DFL) cow dung (CD) FVW. Twelve combinations were designed, varying proportion DFL FVW, keeping amount CD constant at 6 % total solids 37 °C. The maximum biogas yield 809 ± 96 mL/g VSinput was achieved in reactor to ratio 100:0. In contrast, methane 388 131 observed 40:60, also saving 2 (%w/w) extra water than former. proposed strategy potential for full-scale applications its positive attributes.
