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!

Ram pump

The purpose of this tutorial is to facilitate the understanding, design, manufacture and installation of a water elevation system called "Ram pump". This technology was documented during a stopover of the Sea Nomad in the Philippines, on the island of Negros. The NGO "Alternative Indigenous Development Foundation (AIFDI)", based in the city of Bacolod since 1991, helps more than 160 rural communities meet their water needs by installing hydraulic rams throughout the archipelago. The ram pump presented in this tutorial is a different version from the one used by the AIFDI because it is more accessible.
