It has been established that the waste of the alcohol and sugar industry (molasses innovative fertilizer) contains a complex of nutrients, which indicates the feasibility of their use as fertilizers for growing crops. This use of these types of waste will help solve the problem of their utilization, as they accumulate in significant volumes in the areas adjacent to the factories, in storage ponds. At the same time, the issue of reducing soil depletion of key nutrients due to the shortage of traditional organic fertilizers and the high cost of mineral fertilizers will be partially resolved. According to the results of field studies, the effectiveness of using waste in potato fertilization systems on soddy-loamy, bound sandy soil has been proven in order to obtain consistently high yields. In particular, it was found that the introduction of this type of waste at a rate of 10 t/ha ensures the formation of tubers weighing 92.7 g and 66 mm in diameter, and with a twofold increase in the rate — 109.3 g and 74 mm, respectively. These biometric parameters provided potato yields of 19.7 t/ha when using waste at a rate of 10 t/ha and 26.6 t/ha when using 20 t/ha. A positive effect on the quality indicators of potato tubers was recorded when using waste as fertilizer, in particular, the starch content was at the level of 16.6–16.7%. A positive effect of molasses innovative fertilizer on abStract 154 agroecological journal • no. 1 • 2023 the agrochemical parameters of the soil was also found, which is manifested in an increase in the content of nutrients in the tilth layer of soil (0–20 cm): nitrate forms of nitrogen (N–NO3) by 2.0–7.2 mg/kg, ammonium forms of nitrogen (N–NH4) — 0.4–1.1 mg/kg, mobile forms of phosphorus (P2O5) — 5.4–8.4 mg/kg and mobile forms of potassium (K2O) — 26.6– 40.6 mg/kg. The possibility of using waste in combination with mineral fertilizers was noted, which balances the fertilizer system and provides additional growth of potato tuber yield.

Wastewater from bioethanol plants is classified as highly concentrated in terms of organic pollution precisely due to distillery stillage. The main problem in the disposal of distillery stillage is the processing of the liquid phase, the volume of which is up to 92% of all wastewater from a bioethanol plant. The existing wastewater treatment technologies of a bioethanol plant can be conditionally divided into four types: evaporation, aerobic biological treatment with fodder yeast production, anaerobic stillage treatment with biogas production, combined schemes. The aim of our work was to study a combined method for cleaning grain stillage by the anaerobic-aerobic method with the immobilization of microorganisms on a fibrous carrier. Physicochemical parameters of grain stillage and purified methane mash were determined according to generally accepted methods for analyzing wastewater from distilleries. Under anaerobic conditions, biogas was formed from distillery stillage, including low molecular weight organic compounds – methane, carbon dioxide, organic acids. After the first anaerobic stage of treatment, the pollution of wastewater decreased by 8-10 times, after which it was fed to the aerobic stage of post-treatment, which was carried out by microorganisms immobilized on a fixed carrier, which reduced the removal of biomass with the flow of purified water and improved treatment performance. The chemical oxygen demand (COD) of methane mash after the 1st stage of anaerobic fermentation was 1360 mg/dm3 compared to the initial COD of grain stillage of 15800 mg/dm3, which ensured a purification efficiency of 91.4%. The purification efficiency according to biochemical oxygen demand in five days (BOD5) was 97.5%. After the aerobic stage, the purification efficiency was 98.2% in terms of COD and 99.8% in terms of BOD5. The values of the content of total phosphorus also decreased by almost 20 times, nitrogen – by 9 times, sulfates – by 5 times. The advantages of the proposed method of wastewater treatment of bioethanol plants over existing ones are the ability to treat wastewater with any concentration of pollutants and additional obtaining of fuel – biogas, which can be used to replace natural gas, solving the problem of removing the biomass of microorganisms from the purification zone due to their fixation on a fibrous fixed carrier.
