lecture on bio-digester design at the Wawashang School
the food, energy (e.g. biogas), and agricultural inputs (e.g. fertilizers) it needs to function properly. The rural school currently consists of student dormitories, teacher quarters, classrooms, an administration building, a clinic, a woodworking shop, a set of solar panels, several plant nurseries, as well as a coconut, corn and cacao processing facility. The school also has in place a farm, where goats, pigs, chickens, horses and cows are raised. Currently, these set of farm animals produce significant amounts of manure, much of which is no being utilized. As such, the school requested two F2F volunteers that could assist them in implementing low-cost bio-digester systems that can harness the biogas and organic fertilizer produced from manure. Mr. Haugen and Mr. Rohde were the perfect team for this task.
As part of their assignment in Wawashang, the duo of volunteers conducted a series of lectures and hands-on trainings on how to design, build, operate, and maintain bio-digester systems. This included technical insights into the chemistry of the process, various fuel sources, different types and advantages, output use for fertilizer, as well as the environmental impact and benefits of such systems. In particular, the pair of volunteers identified two benefits that the school would obtain with a bio-digester system: 1) clean and reliable source of fuel for cooking (i.e. replacing wood burning stoves), and 2) the fact that digester effluent can be used as a readily available and nutrient-rich fertilizer. Through these presentations and workshops, a total of 6 FADCANIC teachers and 68 students were trained. In addition to helping to establish a bi-digester system for the school, the objective of these engagements was to incentivize faculty and pupils to duplicate these low-cost technologies in their respective villages and farms.
