Abstract
This article presents a knowledge engineering method for carrying out risk-benefit analyzes considering the points of view of different stakeholders, according to various criteria. Several insect-based bioconversion scenarios —a promising technology for the recovery of bio-waste by insects— are explored at an early stage on the basis of currently available knowledge and compared using this method. Inspired by argumentation systems in artificial intelligence, where contradictory arguments interact, the method is based on a synthetic measure of opinion to compare the values of different alternatives (here the scenarios studied), either according to a specific criterion (nutritional, health, etc.) or a particular actor (citizens, etc.), or globally by combining this information. The impacts highlighted lead to the conclusion that the regulatory and health aspects appear to be crucial topics to be dealt with in order to develop insect-based bioconversion sectors, according to the opinion of the actors questioned and the literature consulted.
