Abstract: Human waste is the source of 80-90% of the nutrients found in domestic wastewater, and can be a major path of pathogen  transmission if the wastewater is not treated adequately. Mixing human waste with other wastewater streams also increases the difficulty to reclaim the nutrients. It is therefore a main go al of ecological sanitation approaches to catch and treat human waste as close to the source as possible, and convert it into a safely reusable form. One possible solution is the direct conversion of human feces into biochar by using a pyrolytical process. An experimental pyrolysis batch reactor was developed and built in fall 2014, to pyrolyse human fecal matter from a composting toilet. Ten test runs were performed, five with wood chips and five with fecal matter from a composting toilet. The resulting biochar was analyzed on elemental composition by using X - Ray Fluorescent Spectroscopy. Water content was a major factor influencing energy demand of this process, and must be.
