Biodigestion in Action

November 8, 2012

Over the course of the last several weeks, Island School students spent time kayaking, experienced a hurricane, explored the majority of the island, and additionally, were able to gain intimate knowledge of many of the systems that make the campus run. Most notably, aquaponics, aquaculture, permaculture, and biodigestion were featured as Human Ecology modules during the kayak rotation. During the students’ time learning about biodigestion, they were asked to take a look at the ways Island School falls short of its goals of self sustainability and try to find some solutions. In doing so, students’ learned about the systems that support human life on campus, where waste comes from, how humans get energy, and how we can improve as a community. The focus of their work was mainly turning waste to energy, which led to some hands on work with the biodigestion system. Students learned about the anaerobic process, how biodigestion mimics natural systems, how renewable energy is generated by microbes, and eventually how to put that energy to use. After dinner circle on Wednesday, students ventured to the biodigester to check out some of the applications of biogas. They observed running the gas through a conventional burner system and explored possibilities for how this campus system could develop into the future.
