Abstract-Biogas production from organic waste has become a sustainable alternative for energy generation and waste management, especially for biodegradable wastes like agricultural and floral residues. Flower waste, an often-overlooked source, holds significant potential as feedstock for biogas digesters due to its high organic content. However, optimizing the efficiency of biogas digesters with flower waste requires understanding its unique composition and degradation patterns. This study investigates strategies to enhance biogas production efficiency from flower waste, focusing on preprocessing methods, microbial additives, co-digestion with other organic materials, and optimizing operational parameters like temperature, pH, and retention time. Results show that pre-treatment methods, such as hydrothermal processing or microbial inoculation, increase the biodegradability of flower waste, thus enhancing methane yield. Additionally, co-digestion with complementary feedstocks, like food or animal waste, improves nutrient balance and stabilizes the digestion process. By implementing these techniques, biogas digester performance with flower waste can be significantly improved, leading to higher energy yields and promoting sustainable waste management solutions for floral industries.
