Background: the concern related to fossil energy sources is increased because of the energy crisis that facing the world, therefore, it is necessary to find renewable and environmentally friendly energy sources alternative to fossil energy.
Lignocellulosic materials such as wheat straw can be considered for biogas production, however, its recalcitrant structure restrained its utility.
Therefore, applying a convenient pretreatment method is necessary to increase sugar yield and biogas production.
Carbon to nitrogen ratio of wheat straw is high, so it is necessary to mix it with proper amounts of low carbon to nitrogen ratio material such as a chicken feather to get suitable carbon to nitrogen ratio for anaerobic digestion which is 20-30.
Alkali-microwave pre-treatment assisted to break down the hard structure of wheat straw to improve degradation of cellulose and to release reducing sugars and biogas.
This study aims to examine the effect of alkali-microwave pre-treatment of wheat straw on biogas production with or without pre-treated chicken feather.
Objective: evaluating pre-treatment of wheat straw using microwave irradiation and sodium hydroxide on biogas production from wheat straw.
Methods: in this study, the effectiveness of alkali-microwave pre-treatment on biogas production was investigated, wheat straw was ground and pre-treated with NaOH and microwave irradiation at 2450 MHz and 450 W for (5, 10, 15 and 20 min).
For anaerobic digestion, pre-treated wheat straw was inoculated with an anaerobic consortium, and biogas produced was detected at mesophilic conditions.
Results: it was found that when wheat straw was pre-treated by 2% NaOH at a microwave power of 450 W with 40 g of wheat straw for 10 min in the microwave and mixed with pretreated chicken feather, the cumulative biogas produced was 1870 ml.
Conclusions: alkali-microwave pre-treatment can enhance reducing sugar yield for anaerobic digestion of wheat straw, while the long time of irradiation lead on the decrease in reducing sugar yield.
Adding pre-treated chicken feather for adjusting carbon to nitrogen ratio gave positive results of biogas production
