Abstract

This report guided reader though the research the leads to development of a mobile bioprocessing installation for human feces. It starts off with literature research on the why and how a bio processing can aid in improving sanitation for people in developing countries and solve both the health and environmental issues that are a consequence of it. A good part of the research is focused on how the Black soldier fly larvae and tiger worm can play a part in solving these sanitation issues by revealing their capabilities and complementary relationship in sanitizing human waste and converting it into valuable outputs. The outputs of larvae and worm compost can be sold for value to support the business locally. All the information that is needed to design the optimal environment to harness the two animals inside the bio processor is summarized and converted into requirements which are used to build a small scale prototype and eventually the design of a full scale prototype. The concept development phase went through 4 levels of product development with a creative session, experiment data, and concept presentations taking it to a higher live. The final design of the bio processor which can process the feces of around 200 people is presented in chapter 8 of this report.
