Abstract
In urban and peri-urban areas, where waste management is more than ever a major issue, insect farming may be an ecological way to recycle bio-waste in a circular bioeconomy approach. Indeed, someinsect species such as Hermetia illucens can grow on many types of organic substrates and can convert them into valuable byproducts(1). There may be a wide variety of insect bioconversion products since larvae are a natural source of micronutrients, amino acids and antimicrobial compounds. They are also rich in proteins which can be used for animal feed, in fats used for the production of biodiesel, in chitin used in various industries, and they produce a type of manure called frass that can be used as biofertilizer(2). However, besides its ecological and nutritional benefits, risks of insectbased bioconversion should be identified and monitored. Indeed, some chemical contaminants may be found in insect farming environment, in their feeding substrates or can be produced during processing methods(3). Moreover, microbiological contaminants may be found in the farming insect chain(4). Therefore, it is necessary to assess the impact of these contaminants on insect survival and to determine their fate in the insect. It is also important to assess the environmental, social and economic impact of insect-based bioconversion and to determine the consumer acceptability of these new processes and products
