Data of biogas users and potential biogas users werecollected from Bangladesh. Application of slurry, byproduct of biogas technologyplays a vital role to increase agricultural production as well as improve the soilfertility. This book proves that slurry oriented biogas households are more efficientto Boro rice production compare to biogas non-users. Finally, the book finds thatbiogas is a profitable business considering the financial and economic assumption.All these assumptions are prescribed to provide incentives for extending the biogasbusiness.
