The paper presents the review of scientific publications of world literature on the use of the larvae of black soldier fly (Hermetia illucens) when feeding poultry. Nowadays, the issue of replacing traditional sources of protein when feeding poultry is very urgent, especially in connection with the global food crisis. Insects are the natural food of most birds; thus, the use of fly larvae for feed production has a biological basis. The research results presented in published works show that there are no negative effects on bird health and meat quality when feeding poultry, quail and other birds. In some cases, the experimental groups of birds gained weight slightly more slowly than the control group. Other reports indicate that birds grew at the same rate as normal birds. The quantity and quality of eggs did not differ significantly, but dietary changes affected the colour of yolks and eggshell. The effect of the addition of live larvae to the diet of young turkeys on the weight characteristics of was studied. Replacing 10% of the daily amount of feed with live Hermetia illucens larvae in the diet of turkeys showed that the daily feed intake and body weight gain of the experimental birds were significantly higher compared to the control groups, which led to a significantly higher body weight of chicks at the age of five weeks (2.19 kg vs. 2.015 kg, respectively) and a significantly lower feed conversion rate. Most researchers agree that replacing protein in poultry feed with insect flour should be partial, in the 15–30% range. Feeding with larvae that have undergone processing – grinding, chitin removing, heat treatment – is more preferable than using whole larvae, since the chitinous membrane makes larvae difficult to be digested in the digestive tract of birds.

More than 30% of the world’s food production is wasted. Organic waste and residues are produced in a variety of sectors, including agriculture, food industry and forestry. Residues and waste are generated throughout the entire food production and use cycle: surplus food production, processing and distribution, and consumption. Some food that has not been consumed should be managed. Bioconversion using insects provides the opportunity to produce feed and energy using by-products of the agro-food industry. The aim of the work was to present the concept of “IN OIL: an innovative method for the bioconversion of by-products from food processing industry” under the project LIDER VII (co-financed by the National Centre for Research and Development). Project IN OIL is being implemented at the Poznań University of Life Sciences. IN-OIL’s main assumption is combining two ideas – waste into energy and waste into feed. The developed method will reduce the adverse impact of unused food on the environment by using ReFood products in insect feeding (Hermetia illucens). H. illucens (Black Soldier Fly) is a Diptera characterized by a very high index of growth, and rich source of fats and proteins. The main assumption of the project is based on the introduction of by-products from the food processing industry to feeding with larvae of H. illucens. Biomass of insect larvae will then be processed into products that will be used for feed and energy purposes.
