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.

Black Soldier Fly breeding

This tutorial aims to facilitate the understanding of the life cycle of the black soldier fly and to learn how to grow it for domestic use. This technology was documented during the stopover of the Nomade des Mers expedition in Malaysia. The company EntoFood, which we visited, has been doing research on these flies for nearly 8 years and is preparing to launch its large-scale production unit. It will allow the treatment of 300 tonnes of organic waste per day!
