Optimizing Biogas Production from Organic Waste and Livestock Byproducts: A Case Study on Strategies for Sustainable Food Systems in a Local Municipality in Serbia

In the process of biogas production, various types of substrates with suitable energy potential are utilized, which in turn are used to generate biogas in plants designed for cogeneration (CHP) of electricity and heat. This paper presents a literature review focused on different substrates 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. It highlights the energy potential of different 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. The potential yield of biogas is expressed per tone of fresh, dry, or organic dry weight of the substrate. Furthermore, the findings are utilized to optimize biogas production specifically in the municipality of Čačak. Insights from this review aim to contribute to the development of effective strategies for utilizing diverse feedstocks in biogas plants.
