Thanks for your comment! And thanks for mention of Brazil. In the case of our project, the biogas will be made from kitchen waste, other domestic waste, and agricultural residues. But here are some broader comments as well, from our project colleagues in Solar CITIES Biogas Innoventors and Practitioners. Biogas is a combination of naturally occurring gasses produced by the fermentation of organic matter or what is called biodigestion. Made up predominantly of Methane, CO2, and Hydrogen Sulfide. Methane, the highest percentage, is used for cooking fuel in many areas of the world. An important byproduct is the digester effluent, which is a natural concentrated liquid fertilizer with a perfect NPK value. Much more can go into a biodigester than a compost pile! It can digest more things than just animal manure and garden waste. Things that would typically draw disease carrying rodents and insects, like humanure, dog manure, meat, fish, and fats. A simple TED Talk that describes the process and it’s substantial impact can be found here: https://www.youtube.com/watch?v=zNDPDBmBPzU&t=35s South of the State of Bahia in Brazil are several Solar CITIES projects facilitated by Dr. Thomas H. Culhane. One is in Niteroi at a new elementary school and day care that would use toilet waste and cafeteria waste. Another project is located in a rainforest favela called “Vale Encantado.” Solar CITIES follows a Trainer of Trainers format, to teach and share resources in a way that “fellow practitioners” can easily teach others. Two such people were the late Paulo Mellett, and Fabio Poesia Sambasoul who constructed a biodigester in Sao Paolo.

There are a number of resources available through Solar CITIES and its international network of “Innoventors and Practitioners”. Here are links to a few of them that are shared in hands-on workshops: Building a Biodigester, with Dr. Thomas H. Culhane https://www.youtube.com/watch?time_continue=8&v=4fdAQFh3ClU

Here are two online episodes (classes) from Dr. Thomas H. Culhane at the University of South Florida’s Patel College of Global Sustainability. Episode 1: Introduction: Navigating the Food/Energy/Water Nexus: Synergizing for Sustaining https://www.youtube.com/watch?v=yqBYNCwT-sc ; Episode 2: Avoiding the Tragedy of the Commons and Reducing our Ecological Footprint through the Nexus https://www.youtube.com/watch?v=sszV_ThOjVE . Best wishes! We would be happy to connect with you at a convenient time.

My pleasure! My blog didn't last very long, and I was a novice blog-writer, but here is the entry on Haiti Communitere: http://sophie822.blogspot.com/2012/03/monday-02202012-port-au-prince-haiti.html

Hello Christopher, great initiative. Lack of access to electricity is a big problem in Haiti, and it's unfortunate that you have to resort to inefficient, expensive diesel-fueled generator. Our consortium will also be working in Cotes-de-Fer. Specifically, one of consortium members, Konbit pou Developman Communte Kotes-de-Fer (KDCK) has already introduced biogas digesters and Solavore solar ovens in the area. It is possible to run generators off of biogas from organic waste materials. For example, the hospital you mentioned could safely dispose of hazardous organic waste by feeding it into a biodigester. Biodigesters can also be attached to toilets to collect human waste. Have you considered this option? KDCK, and the BioScience/medical University of Notre Dame d'Haiti in Hinche will be our main partner exploring these options through a human-centered design approach. Perhaps we could work together.
