Specific details on the construction and operation of these plants are available in the Practical
Action technical brief Using a Biogas Digester. For more details and case studies on how
individuals have benefitted from these technologies see the Practical Action biogas homepage.
An alternative to the above is a ‘compact’ biogas digester, which can produce a usable fuel from
the degradation of waste foodstuff. This can be particularly useful in scenarios where the owner
and operator of the machine does not have cattle or other animal stock. The technology has been
developed by the Indian Appropriate Rural Technology Institute, and can produce gas from a
variety of feed stocks, including waste flour, vegetable residues, waste food, fruit peelings, rotten
fruit, oil cake and rhizomes of banana (ARTI, 2006). Details of this solution are covered in the
Biogas technical brief, with a specific building manual ARTI Floating Dome Biodigester also
available.
