Special Issue Information

Dear Colleagues,

The sustainable management of organic waste and wastewater has become a critical global challenge due to increasing population and industrial activities. Recent advancements in bioenergy technologies have opened new pathways for converting organic residues and effluents into valuable energy products such as biogas, biohydrogen, and bioethanol. The integration of advanced biological, chemical, and physico-chemical processes—including anaerobic digestion, microbial electrochemical systems, photocatalysis, and thermochemical conversion—has shown great potential to enhance energy recovery efficiency and environmental performance.

This Special Issue, entitled “Advanced Technologies for Bioenergy Recovery from Organic Waste and Wastewater”, aims to highlight recent progress in innovative materials, process optimization, hybrid systems, and modeling approaches that contribute to sustainable energy generation and resource recovery. We welcome scholars to submit original research articles, reviews, and case studies focusing on novel technologies, process intensification, and environmental benefits associated with bioenergy recovery from waste-based resources.

Intensive swine production contributes significantly to the global protein supply but generates considerable environmental pressure, particularly through greenhouse gas emissions and surplus slurry management. Anaerobic digestion (AD), especially (co-AD), has been widely investigated as a mitigation strategy to enhance renewable energy generation and nutrient recovery. This systematic review synthesizes life cycle assessment (LCA) studies published between 2019 and 2025 that evaluated AD systems treating swine slurry, following the PRISMA 2020 guidelines. Across diverse methodological approaches and regional contexts, the literature consistently shows that AD can reduce global warming potential compared with conventional slurry management, with stronger environmental benefits when biogas is efficiently valorized and when swine slurry is co-digested with complementary organic substrat. Co-AD emerges as a key mitigation option by improving biogas yields, process stability, and overall environmental performance while also enabling better utilization of external organic waste. However, the results remain highly sensitive to operational factors such as methane leakage, digestate management, energy efficiency, and substrate selection. This review highlights the methodological inconsistencies among LCA studies and underscores the need for harmonized assessment frameworks and improved emission data. Overall, co-AD represents a promising pathway for enhancing the environmental sustainability of swine production systems when integrated into optimized, context-specific management strategies.
