The purpose of this research was to analyze the biogas production from co-digestion of Salvinia molesta and rice straw. Ratio of Salvinia molesta and rice straw was 5:0, 4:1, 3:2. Lab-scale-batch digesters (600 mL) were operated at room temperature (30 oC) and pressure of 1 atm. Total basis of Salvinia molesta and rice straw was 10 gr, water was added with ratio of organic matter:water = 1:7 (w/w), rumen fluid was added as inoculum, initial pH was adjusted to be 7. Fermentation process was conducted for 30 days. The results showed that total biogas volume for ratio of 5:0, 4:1, 3:2 was 6.300.00; 32.7618.32; 107.5418.51 mL/g VS respectively. The pH of substrate was changing from 7.00 to 6.770.19; 6.600.14; 6.730.09 for all variables respectively.

To discuss the effect of NaOH pretreatment technology for biogas production and methane (CH4) content enhancement during the anaerobic digestion of rice straw waste, a self-designed laboratory-scale continuous anaerobic biogas digester was used in this study. Anaerobic biogas slurry, NaOH pretreatment and anaerobic digestion were evaluated for biogas production from rice straw. The results showed that the peak value of biogas production was attained on the 16th day by using 6% NaOH pretreatment on rice straw. However, the highest CH4 content was 60.8% on the 24th day for the 4% NaOH-treated rice straw. The cumulative biogas production of 6% NaOH pretreatment was the highest, about 18 720 mL, which was followed by 8% NaOH (15 057 mL), 4% NaOH (12 103 mL), and 2% NaOH (10 754 mL).

Pretreatment Temperature

Organosolv pretreatment was used to improve solid-state anaerobic digestion (SSAD) for methane production from three different lignocellulosic substrates (hardwood elm, softwood pine, and agricultural waste rice straw). Pretreatments were conducted at 150 and 180°C for 30 and 60 min using 75% ethanol solution as an organic solvent with addition of sulfuric acid as a catalyst. The statistical analyses showed that pretreatment temperature was the significant factor affecting methane production. Optimum temperature was 180°C for elmwood while it was 150°C for both pinewood and rice straw. Maximum methane production was 152.7, 93.7, and 71.4 liter per kg carbohydrates (CH), which showed up to 32, 73, and 84% enhancement for rice straw, elmwood, and pinewood, respectively, compared to those from the untreated substrates. An inverse relationship between the total methane yield and the lignin content of the substrates was observed. Kinetic analysis of the methane production showed that the process followed a first-order model for all untreated and pretreated lignocelluloses.
