Biogas sludge as organic fertilizer

[Vinaya]

I live in a farm and I have cattle. I also have a biogas plant.I feed my biogas plant with cattle waste which produces gas for our kitchen. We get free gas for 356 days. Apart from free gasm we also get high quality compost. The biogas plant gives sludge which is high quality fertilizer.

This is quite commendable. Biogas technology has been embraced in my region by many farmers who practice dairy farming. There are also innovations of collapsible tanks which save on construction costs of biogas plants. Its a win-win technology since the environment also benefits as its cheap, renewable and pollution free.
