The Biogas Digester Expert: Small scale farm and rural community biogas section 

Biogas digesters take any biodegradable feedstock, and convert it into two useful products: gas and digestate. In this section we will concentrate on small scale farm and rural community biogas applications.

A number of popular simple designs of digester have been developed; the Chinese fixed dome digester and the Indian floating cover biogas digester .  Development has taken place over many years and each nation tends to have its own preferred design. While international collaboration over the next few years can probably develop and improve these designs, by incorporating the best worldwise experiences, local designs will no doubt be well optimized for local farming practices and the types of waste available.

   Biogas plants produce a high calorific value gas which similar to natural gas and do this using the anaerobic digestion process. Biomass is digested in plants ranging from the size which might serve one house or a small farm up to much larger plants which tend to be highly complex and take a variety of feedstocks from various sources.

At the end of the 1990s, probably about five and a quarter million farmer households had biogas digesters, worldwide.  However, most national governments would like to see many more installed as after the operation of biogas digester, it is no longer a significant source of pollution. The economic viability of these plants is rising fast as oil prices soar ever higher and the date of peak oil production for the globe gets closer.

Some family biogas digesters even support small-scale enterprises,by providing electricity for agricultural and cottage industries.  The advantages of using a biogas digester to convert human waste and cow dung into an easily accessible alternative energy source do not stop at cheaper power and free time. 

In addition, there are added health benefits to the use of the biogas digester.  In regions where there is already a mature electrical grid, there is limited incentive to use simple biogas digesters because they are not easily scaled up to produce energy comparable to hydropower and coal.
