Kinetic Modeling of Biogas Generation from Banana Stem Waste

A kinetic model for biogas generation from banana stem waste was proposed on the basis of the obtained experimental results. The system consists of an anaerobic sequencing batch reactor for the ﬁrst stage and an anaerobic ﬁxed bed reactor for the second stage, which is operating at hydraulic retenti...
