Biodiesel

This tutorial gives you the process on how to make biodiesel on a medium-scale (about 50L) from used cooking oil. This tutorial was written following the Nomade des Mers crew's visit to Cambodia. The social enterprise Naga Earth collects and converts used cooking oil from the town's hotels and restaurants into biodiesel. They also make soap with glycerin that comes from this same reaction. This benefits various schools and associations who carry out hygiene programs throughout the region.
