Actual linear food-system
Since the beginning, humanity and waste generation have always been linked. There was a time when there was a balance between waste production and the “recycling capacity” of our ecosystems. Today, the exponential population growth, rapid urbanization, and rising living standards in developing countries have caused excessive use of our resources.
Have you ever heard of Deposition Day?
It is the day of the year from which humanity is supposed to have consumed all the resources that the planet is able to produce in one year to regenerate this consumption or to absorb the produced waste. In 2022, it was on the 28 of July.
This observation allows us to visualize two important points. The first is that the production system relies on limited resources, and the second is that this system generates waste. It is estimated that 30% of food waste occurs along the supply chain.
Wastech circular food system
The circular model integrates a completely different consideration of the resource. At the end of the linear model, the resource is seen as a waste, whereas in the circular vision, this waste is a resource.
In order for it to be reintegrated into the model, our tool is the Black Soldier Fly culture
As you can see in the diagram below, this crop not only allows us to create two different loops, it also avoids overexploitation of some limited resources.
