Thermal pre-treatment – A prerequisite for the reduction of hydrolysis stage during anaerobic digestion of Ageratum conyzoides

The present study mainly focussed on the effect of different thermal pretreatments on Ageratum conyzoides. Thermal pretreatment reduced the hydrolysis period and, at the same time, increased biogas production as compared to the untreated Ageratum conyzoides. The effects of four different thermal pre...

Thermal pretreatment reduced the hydrolysis period and, at the same time, increased biogas production as compared to the untreated Ageratum conyzoides. The effects of four different thermal pretreatment techniques, i.e., hot air oven, microwave, autoclave, and hot water bath on the anaerobic digestion of Ageratum conyzoides were studied. Autoclave pretreatment was found to be more efficient, followed by a hot water bath, hot air oven, and microwave pretreatments. Autoclave pretreatment enhanced the solubilization.
