The effect of microwave pretreatment on biogas production from agricultural straws

- Barley, spring wheat, winter wheat and oat straw were examined.
- Microwave pretreatment were performed at 200 and 300 °C.
- The biogas production performance was investigated.
- Specific methane yields were not improved by microwave irradiation.
- Conversion yield and cumulative biogas production have inverse relations.
