Abstract

The effect of total solid (TS) content and feedstock/inoculum (F/I) ratio  on biogas production from corn stover by solid‐state anaerobic digestion (SS‐AD) were studied. At a F/I ratio of 2, conversion of corn stover under room temperature resulting in higher biogas yield. SS‐AD performed as expected at the TS content of 20%, 22%, 24%. The highest biogas yield of 200 L kg‐1 volatile solids (VS) was obtained at TS content of 22%, F/I ratio of 2.

Abstract

The shortage of fossil fuel can be minimized by developing renewable energies such as biogas. The raw material of biogas can be derived from corn stover. Biogas was produced under solid-state anaerobic digestion (SS-AD) and liquid anaerobic digestion (L-AD). The objectives of this study were to compare the biogas yield and analyze the pH value and VS degradation. The results reported that the SS-AD generated a higher biogas yield than L-AD. SS-AD could improve the biogas yield of 71%. Both SS-AD and L-AD had a higher final pH than the initial pH. Moreover, the VS degradation was proportionate to the biogas yield. The highest VS reduction was achieved on SS-AD. Keywords: anaerobic digestion, biogas, liquid state, solid state, volatile solid, renewable energy
