“…In Western countries the main substrates currently used for insect production thus include commercial animal feed, co-products from the primary production of nonanimal origin food, and former foodstuffs (not containing meat and fish) for example production surplus, misshapen products, food with expired best-before-dates that have been produced in compliance with food legislation which have been already proposed as valid carbohydrates/energy sources in animal nutrition (Giromini et al, 2017;Luciano et al, 2020;Ottoboni et al, 2019;Pinotti et al, 2019Pinotti et al, , 2020Pinotti et al, , 2021Tretola et al, 2019). By contrast, in other countries (e.g.…”

Insects are able to convert organic material (i.e. waste and by products) into high-quality biomass, which can be processed into animal feed. Several studies have investigated the influence of growing substrates on the nutritional value of different insect species, particularly black soldier fly larvae and prepupae. This article reviews studies on how insects bioconvert different substrates, the effect of the substrate on the composition of insect meals, and on the development time (time needed to reach the harvesting state). All these studies indicate that insects convert low and high quality organic material (i.e. waste, by products, compound feeds) into high-quality insect biomass. The role and effects of selected nutrients, such as ether extract/fats, carbohydrates and fibre in the substrate, seem to be key factors in defining the features of the biomass as well as the time needed to reach the harvesting state.

Livestock feed encompasses both human edible and human inedible components. Human edible feed components may become less available for livestock. Especially for proteins, this calls for action. This review focuses on using alternative protein sources in feed and protein efficiency, the expected problems, and how these problems could be solved. Breeding for higher protein efficiency leading to less use of the protein sources may be one strategy. Replacing (part of) the human edible feed components with human inedible components may be another strategy, which could be combined with breeding for livestock that can efficiently digest novel protein feed sources. The potential use of novel protein sources is discussed. We discuss the present knowledge on novel protein sources, including the consequences for animal performance and production costs, and make recommendations for the use and optimization of novel protein sources (1) to improve our knowledge on the inclusion of human inedible protein into the diet of livestock, (2) because cooperation between animal breeders and nutritionists is needed to share knowledge and combine expertise, and (3) to investigate the effect of animal-specific digestibility of protein sources for selective breeding for each protein source and for precision feeding. Nutrigenetics and nutrigenomics will be important tools.

“…Dry waste of grain processing (bran) (4) and sludge from the filter (5) are fed there to reduce moisture and as a bonding structure of granules. Then the granules are fed onto the conveyor rollers (6). For rapid heating of granules, microwave emitters (8) with an exposure of 3 -5 min were used.…”

“…With countercurrent movement of gas and liquid through the spherical elements of the charge 15, a film of liquid and drops are formed on them. Through drops, a liquid film on the wetted surface (up to 80% of the total area of the packing element) and through the liquid surface in the recesses, the processes of further diffusion of the chemical components of the gas into the absorbent take place [5][6][7][8].…”

Liquid waste of food industry enterprises contains various valuable organic substances of natural origin, which can be rationally used to obtain feed proteins. The problem of using valuable substances from food waste solves the problem of using biotechnological methods in order to use methods of accumulating biomass, enzymes, vitamins, etc. The biomass of unicellular microorganisms formed in the process of cultivation can be a raw material for obtaining feed additives and other biologically active substances.
