Summary/Abstract: The report focuses on livestock waste management, which is a key aspect of sustainable agricultural development. Animal waste, including excreta, bedding materials, waste feed, dead animals, and other by-products, represents a significant environmental pollutant. Proper management of this waste is essential not only for environmental protection but also for reducing farm costs, creating new market opportunities, and increasing the sector’s competitiveness. The adoption of innovative practices in livestock waste management is a modern solution aimed at transitioning towards a circular economy and supporting the European Union’s green policies. The main methods for effective waste management include anaerobic digestion and pyrolysis. An-aerobic digestion is a process that occurs in the absence of oxygen and allows for the conversion of organic waste into biogas. This biogas can be used as a renewable energy source, significantly reducing pollution and decreasing reliance on fossil fuels. Another important by-product of the process is biosolids, which can be utilized as fertilizers to improve soil fertility. Pyrolysis, on the other hand, is a thermal decomposition process of biomass without oxygen, producing bio-oils and biochar, which also have applications fuels and soil conditioners. The report highlights the social, economic, and environmental benefits of proper livestock waste management. Effective waste utilization contributes to improving soil structure, reducing methane emissions, and limiting water pollution. One of the most common methods of waste management is the application of manure to agricultural lands, which enhances the organic content of the soil. How-ever, improper or excessive use of manure can lead to nutrient overload and environmental contamination, underscoring the need for precise management. Innovations such as the use of artificial intelligence and blockchain technologies provide new opportunities for process optimization. These technologies help farmers manage resources more efficiently and reduce the negative impacts on the environment. The report concludes that integrating technology, improving regulatory frameworks, and investing in farmer education are essential for sustainable livestock waste management. By adopting these measures, livestock waste can be trans-formed into a valuable resource, supporting both agricultural sustainability and the global circular economy.
