Abstract
The increasing demand for sustainable energy and efficient waste management has driven global interest in biogas production. This study examines the sustainability of biogas production from organic waste in Dubuque, Iowa, focusing on its feasibility, efficiency, and potential impact on waste management and renewable energy generation. This research assesses the availability of organic waste as a feedstock, evaluates the operational practices at The Waste and Resources Recovery Center (WRRC), and investigates the environmental, economic, and social implications of biogas production. Quantitative analysis was employed. Primary data were gathered through facility reports, operational records, and an on-site observation with the plant manager. Statistical analysis, including regression modeling and time-series forecasting were conducted to evaluate biogas yield trends and the factors influencing production efficiency. Findings reveal that while biogas technology offers a viable solution for sustainable energy generation, operational challenges such as fluctuating feedstock composition, digester inefficiencies, and regulatory barriers hinder optimal production. The study highlights the potential of biogas in reducing greenhouse gas emissions, contributing to circular economy practices, and supporting local energy needs. However, improving feedstock management, enhancing process efficiency, and strengthening policy frameworks are necessary to ensure long-term sustainability.
This research provides valuable insights into the role of biogas in urban sustainability strategies, emphasizing the need for technological advancements and policy interventions to maximize its benefits. The findings contribute to the growing body of knowledge on waste-to-energy systems and offer recommendations for optimizing biogas production in mid-sized cities like Dubuque.
