enrich biomass (soybean meal) with microelements [such as Zn(II), Cu(II), Mn(II) and Fe(II)] that are essential in livestock nutrition to produce dietary feed supplements. The biosorption process was carried out in a specially designed pilot plant system with two-column reactors according to the principles of the eco-friendly effluent-free technology. The applicative parts of products and innovative biological feed supplements were produced for zoo-technical tests on animals (hens, goats and fatteners). Multielemental analysis showed a multiple increase in the content of each microelement in the soybean meal after biosorption [of Zn(II)-168 times, Cu(II)-179 times, Mn(II)-62 times and Fe(II)-50 times]. The process was analyzed in terms of technological indicators and preliminary economic analysis, including the cost of materials, labor costs and depreciation of the equipment used. It was found that the cost of supplementation of 1 kg of feed for laying hens and fattening pigs with the new preparation enriched with Cu(II) and manufactured on a technical scale was around $0.393.
