Sweating the Small Stuff

Our latrine structure is nearly complete. From the outsiders perspective we have finished. While the latrine itself is done there remains a significant amount of work related to the start-up of the microbial communities required for our fuel-cell.

For example, we need a critical mass of microbes in both the anode and cathode of the fuel cell prior to sending any waste to the system. So, we must in inoculate our MFC and provide organic material. The solution: dog food. By adding the dog food to our bacteria, we can feed and grow the bacterial until they can handle human waste. The warm and humid climate of southern Ghana creates an excellent environment for bacterial growth. This, in combination with the locally sourced dog food, should enable us to start-up our system relatively quickly with a strong microbial community.
