Abstract.Anaerobic digestion (AD) is a well-established biological process that converts organic waste into valuable products, including biogas, digestate, and nutrient-rich effluent. This review summarizes the current understanding of AD products, with a focus on their characteristics, applications, and the challenges associated with their utilization. Biogas, primarily composed of methane and carbon dioxide, serves as a renewable energy source, while digestate and liquid effluent can be used as soil amendments and liquid fertilizers, respectively. However, the variability in substrate composition, process instability, and the need for post-treatment of digestate remain significant challenges. This review also highlights recent advances in pretreatment and co-digestion strategies to enhance product yield and quality, contributing to the circular economy and sustainable waste management.
