This is my favorite low-tech on board ! Let me present you the Black Soldier Fly ! The larvae of this fly can eat any organic waste with a very high efficiency and turn it into a very valuable ressource We have been in Malaysia to meet Emilie who is a world expert. At the Low-tech Lab, we travel the world to find the best low-tech ! Inventions that are useful, sustainable and accessible to all. For us, the use of the Black Soldier Fly is amazing because it’s an insect that can convert almost any type of organic waste Into an insect meal that we will use in animal feeding: for chicken, pig, fish, etc. And in a compost that will also be reused in agriculture Here when we receive 1 ton of organic waste we turn it into 200 kg of larvae and into 200kg of compost Thanks to these flies we will collect eggs. With about 1 kg of eggs in 15 days, we get about 5 tons of larvae which is the equivalent of an elephant ! We are contributing to sustainable farming like that reusing waste to produce insect biomass and compost so to produce value I find it very exciting ! I’ll show you how to raise Black Soldier Fly at a small scale Put your organic waste into this box They can eat any waste that is not to dry We even give the larvae our dry toilets. When they have eaten enough They will turn into pupae climb this ramp and fall into the tray Once a week, you harvest 90% of the larvae to feed the animals It’s full of lipids and proteins You put the rest in the aviary They will become flies reproduce themselves and lay their eggs into this cardboard Babies will hatch, and jump into the food. In a big waterproof box, build a ramp with some waterproof wood. This will let the larvae get out of the wet subtrate when they will be ready to pupate. On this ramp, add 2 barriers, to guide the larvae to the box where they will fall and could be collected. Build a cover for the box. If the larvae don’t have enough food, they will try to get out by any small interstice. Build an aviary for the adult flies. The top of the aviary can be covered by a plastic sheet to protect the eggs from the rain if the aviary is placed outside. Cover the rest of the aviary with mosquito net and build a door to access the inside and collect the cardboard where the flies will have lay their eggs. Use 3 small boxes. In the first one, add a damp cloth where flies can drink On the second, place the pieces of cardboard where the flies can lay their eggs In the third tank, add the dry substrate with the fly pupae. One third of our garbage is organic waste. We use a lot a energy to make them disapear This little quiet fly, is a ready-made technology, free of cost, and highly efficient Everybody should use it !
