o:7997 Assessing Biogas Production Potential from Organic Waste and Livestock Byproducts in a Serbian Municipality: Implications for Sustainable Food Systems en Abstract: In the process of biogas production, various types of substrates with suitable energy potential are utilized to generate biogas in plants designed for cogeneration (CHP) of electricity and heat. This paper presents a literature review focused on different sub- strates involved in biogas production, emphasizing their optimization potential. Data for this research were gathered through a comprehensive review of scientific and scholarly literature from global databases. The study examines the biogas production capabilities of various feedstocks employed in cogeneration plants, highlighting the energy potential of substrates, including livestock byproducts such as liquid and solid manure, energy crops, organic waste from the food and slaughterhouse industries, as well as municipal wastewater and solid organic waste. Furthermore, we conducted a practical case study in the municipality of Cˇ acˇak, which provides valuable insights into effective practices and strategies that can be broadly applied to enhance biogas production in similar contexts. The findings reveal significant variations in biogas production potential among different substrates, emphasizing the importance of strategic selection and management practices. This study contributes to the field by providing a clearer understanding of the substrate op- timization process and practical insights that can inform the development of more effective biogas production strategies in local municipalities. biogas production; optimization; substrates; livestock byproducts; organic waste; Serbia https://doi.org/10.3390/ su17073144 2025-07-22T11:16:47.776Z 44 yes 46 Srećko Ćurčić aculty Technical Science in ˇCaˇcak, University of Kragujevac Assessing Biogas Production Potential from Organic Waste and Livestock Byproducts in a Serbian Municipality: Implications for Sustainable Food Systems https://orcid.org/0000-0002-6632-293X Dragan Milićević Institute of Meat Hygiene and Technology Assessing Biogas Production Potential from Organic Waste and Livestock Byproducts in a Serbian Municipality: Implications for Sustainable Food Systems person https://orcid.org/0000-0001-9001-0584 Nataša Kilibarda Department of Pharmacy, Singidunum University Assessing Biogas Production Potential from Organic Waste and Livestock Byproducts in a Serbian Municipality: Implications for Sustainable Food Systems person https://orcid.org/0000-0002-2967-3749 Aleksandar Peulić Faculty of Science, University of Kragujevac; Faculty of Geography, University of Belgrade Assessing Biogas Production Potential from Organic Waste and Livestock Byproducts in a Serbian Municipality: Implications for Sustainable Food Systems person https://orcid.org/0000-0003-3043-6879 application/pdf 1548677 https://unilib.phaidrabg.rs/o:7997 no yes 19 70 92000004 71A01 Sustainability 17 MDPI 2025
