The Voronezh Region is a highly developed agro-industrial complex that exerts a burden on the environment. The article deals with the disposal of wastewater pollution with the production of technological products. The aim of the study was to create a biostimulator of plant growth from the waste water of a meat processing plant by enzymatic hydrolysis with the addition of 5% of a consortium of microorganisms from the intestines of pigs and to study its properties on the seeds of Scots pine. The resulting hydrolysates have a high biological value with a complete amino acid composition. The biostimulator contains 92.52% amino acids. Identification of growth stimulation of seed sowing qualities was determined in the laboratory. The results of the experiment show that in the control sample, the seeds were soaked with distilled water, the germination energy was 71.3%, and the laboratory germination rate was 82%. When studying the prototype impregnated with a biostimulator, the germination indicators were: germination energy 85.3%, germination 93.3%. The resulting amino acid biostimulator increased the shelf life of seeds by 11.3%. The biostimulator helped to increase the quality class of seeds, which allows to reduce the seeding rate per unit area during sowing and reduce costs.
