Nepal Pyrolyzer Heat Recirculation
The Nepal Pyrolyzer Project is working with a community in Nepal to optimize kilns used to produce
biochar. With a high supply of invasive lantana to use as the feedstock for the kilns, the main issue in the
production process is the final biochar quality. While biochar has applications in farming, fuel, and water
purification, it is only effective when pyrolyzed at high temperatures (above 400 C) .
The goal then for this project is to modify the current kiln design to recirculate heat during the pyrolysis process,
Thereby increasing overall inside temperature and biochar quality. Currently, the team is developing a
computational model of the heat flow through the new kiln design and is beginning to prototype.
