With the growing world population and the rapid urbanization, there is a need to find alternatives to conventional protein sources for food and feed but it is also necessary to find new ways to manage organic waste. To respond to these challenges, farming insects may offer new options with two main scenarios in a circular bioeconomy approach. Firstly, insects like yellow mealworm (Tenebrio molitor) are already exploited for food and feed as sources of high-quality proteins, PUFAs and micronutrients(1). Secondly, some insect species, which can grow on many types of substrates like black soldier fly (Hermetia illucens), could be used in urban areas for biowaste recycling with the production of varied valuable by-products derived from insects like biomaterials (chitin), biofertilizers (frass), biofuels (produced from larvae fat)(2). Learning form the BSE crisis, it is essential to ensure the safety of these insect products for the development of these new practices
