Technology For Processing Dairy Industry Waste And Sewage Sludge Into Organic Fertilizers

(MENAFN- RCTT) Polesie Agrarian Ecological Institute offers consumers a technology for processing waste and sewage sludge from dairy industry facilities into organic fertilizers- under a commercial agreement with technical assistance and/or a licensing agreement-and is looking for partners to conclude a technical cooperation agreement. Description Processing waste and sewage sludge from the dairy industry into organic fertilizers is a key area within the fields of eco-friendly technologies and sustainable development.
Importance of dairy industry waste processing.
1. Environmental safety:
- Reducing environmental pollution through the utilization of organic waste and sewage sludge.
- Preventing emissions of methane and other greenhouse gases.
2. Efficient resource use:
- Transforming waste into a valuable product: organic fertilizer.
- Reducing the need for chemical fertilizers by using natural alternatives.
3. Economic benefits:
- Lowering waste disposal costs.
- Potential for generating additional revenue from the sale of organic fertilizers.
4. Sustainable agriculture:
- Improving soil structure and fertility through the application of organic fertilizers.
- Maintaining ecological balance in agro-ecosystems.
Key technologies for processing waste and sewage sludge.
1. Anaerobic digestion (biogas plants):
- Converting organic waste into biogas (methane) and digestate (liquid fertilizer).
- Advantages: simultaneous production of energy and fertilizer.
2. Composting:
- Mixing sludge with other organic materials (e.g., straw) to produce compost.
- Advantages: technological simplicity and scalability.
3. Vermicomposting:
- Using earthworms to process organic waste into vermicompost (humus).
- Advantages: production of high-quality organic fertilizer.
4. Drying and granulation:
- Drying sewage sludge and processing it into granular fertilizer.
- Advantages: ease of transport and storage. 5. Chemical stabilization:
- Treatment of sludge with lime or other reagents to neutralize pathogens and stabilize organic matter.
- Advantages: enhanced fertilizer safety.
6. Membrane technologies:
- Use of filtration and reverse osmosis to separate solid particles and concentrate nutrients.
- Advantages: high degree of purification.
The technology developed at the Polesie Agrarian Ecological Institute concerns the processing of sewage sludge (SS) from dairy processing plant treatment facilities into organic fertilizers. The technological solution is based on the forced dewatering of sludge-derived from mechanical and physicochemical treatment processes as well as excess activated sludge-via filtration or centrifugation. This is followed by SS stabilization under aerobic conditions or through an anaerobic digestion stage, and disinfection via composting or the application of disinfecting and neutralizing reagents (which also serve to improve the organic fertilizer's consumer properties). Reagents used may include lime, ash, crushed slag, dolomite flour, ground limestone, sugar production lime cake (defecate), sawdust, foliage, or straw. The reagent quantity ranges from 10.0% to 40.0% of the mixture's weight. Key factors in selecting SS processing methods include sludge composition and quantity, equipment and reagent costs, and environmental safety. The technical outcome is the comprehensive processing of industrial wastewater sludge to produce an environmentally safe organic fertilizer.
Information on the technology is available in the catalog "100 Best Developments of the National Academy of Sciences of Belarus for the National Economy (2022–2023)," pp. 155–156. Advantages and Innovations The implementation of this technology enables the processing of the facility's entire volume of sewage sludge. The solid fraction (approximately 8.5% of the total sludge mass) is converted into organic fertilizer, while the liquid fraction (centrate) from the dewatering process is routed to the intake chamber of the wastewater treatment plant. The resulting sewage-sludge-based organic fertilizer is intended for agricultural use to improve the fertility of low-quality soils and increase crop yields. The product is environmentally safe, requires low application rates, and is free of weed seeds; it boosts crop yields by 15–30%, supplies essential organic nutrients and trace elements, improves soil structure and fertility, and ensures balanced crop nutrition. This sewage-sludge-based organic fertilizer offers excellent agronomic properties and does not generate dust.

Research areas:
- Agrobiology. Scientific substantiation of key elements in the cultivation technology for forage crops (including non-traditional varieties) and the establishment of highly productive, environment-stabilizing plant communities in agro-ecologically challenged areas of the Western Polesie agricultural landscape, taking into account modern climate change;
- Biogeochemistry and Ecotoxicology. Study of the migration of xenobiotics (compounds foreign to living organisms that do not participate in cellular structural or energy metabolism) within ecological systems and the mechanisms of their incorporation into natural cycles; investigation of the consequences of altered natural material flows in the biosphere-such as ecological imbalances, transformation of biosphere components, biodiversity loss, and human health risks. Primary efforts focus on studying the impact of heavy metals on the biotic and abiotic components of ecosystems, as well as their biological and ecological fate;
- Ecosystem Optimization. Intensification of innovative approaches to the conservation and interactive use of landscape and biological diversity and the agricultural potential of the Polesie region, in the interests of sustainable development and improved quality of life. Promotion of environmental and socio-economic innovations within the framework of local sustainable development strategies and "green" economy projects in the Belarusian Polesie;
- Hydroecology and Ecotechnologies. Assessment of water quality (drinking, surface, and wastewater); numerous projects are being implemented regarding the setting of standards for water protection and use, as well as waste processing; scientific research is being conducted in relevant and promising areas related to improving water quality in our region and minimizing pollution risks;
- Feed quality. Analysis of compliance by agro-industrial organizations with technological regulations and standards during agricultural production.
Research is being conducted within the framework of international collaborations and projects across various scientific fields, including ecology, soil science, zoology and botany, hydrology, biogeochemistry and ecotoxicology, plant physiology and biochemistry, and agricultural sciences.
