Why is Biogas Not Being Widely Used in Humanitarian Relief?

Hello All,

Thank you for your very interesting discussion on this topic. Your inputs have highlighted some key issues such as the often complex nature of biogas technology, initial infrastructure costs, available feedstock, community acceptance and the on-going management of a system. Benefits have also been discussed such as the potential for a sustainable energy system using human waste as a primary feedstock and yielding nutrient rich fertilizer. Such a system could support local agriculture and possibly afforestation in the case of longer term settlements.

It seems that more information is needed with regard to the types of system that might be appropriate to a transitional settlement or refugee camp. Biogas systems can be scaled to suit the needs of a community or, on the other hand, small-scale digesters can be self built to serve the cooking needs of a single household.

Case studies are also needed giving a picture of how systems have been implemented and by whom. There are a growing number of biogas programs around the world and a wealth of information is becoming available to support the growth and development of future programs.

To help address the need for more information HEDON will soon be launching a Digester Database that will be searchable by type, application, availability, feedstock and geographic region. Notice of the launch will be posted on this SIG and your feedback will, of course, be welcome.

Warm regards,
