Project Significance

My passion project is designing and building a composting toilet and biogas digester system. The system will allow people to produce biogas for cooking and running generators; compost; and liquid fertilizer all using My passion project is designing and building a composting toilet and biogas digester system. The system will allow people to produce biogas (for cooking and running generators), compost, and liquid fertilizer all using what is collected in the toilet. The system will complete the human nutrient cycle replacing of the disaster of a system and wasteful cycle that we have today. I became fascinated with composting toilets by researching tiny houses. Toilets are an easy way to get people to live sustainably because everyone goes to the bathroom. The current composting toilets on the market are neither user-friendly nor part of a system with a biogas digester. My goal is to design a composting toilet that has a familiar user experience and requires no instructions, unlike the competitors. It is crucial for the toilet to be easy to use to get a global audience to switch to this system. My composting toilet is also waterless thereby reducing the large volume of freshwater being wasted on flush toilets. Separating liquids from solids also has the advantage of reducing smell and allows everything collected in the toilet to be used as a renewable resource. This technology has an application on a global scale because in areas without an established toilet system it can provide sanitation, a source of electricity, and agricultural resources. On the other hand, in areas with established toilet systems it can reduce freshwater usage, artificial fertilizer usage, and the harm done to natural ecosystems by sewage treatment plants.
