From Organic Waste to Renewable Energy: Rice Straw

Organic waste production poses significant global challenges, with mismanagement leading to adverse consequences for individuals and the environment. Anaerobic digestion, a biological treatment technique, offers a solution for processing diverse biological wastes while also producing renewable energy. This chapter explores the impact of various parameters on generation of biogas during digestion of rice straw anaerobically. Approaches like codigestion with various substrates are found effective in enhancing nutritional balance and increasing biomethane outputs. Different pretreatment techniques are discussed as means to improve digester performance. The review also addresses the digestion of rice straw on various scales, considering strategies to overcome barriers and enhance biomethane production. By understanding the factors influencing anaerobic digestion and employing innovative tactics, this research aims to contribute to sustainable waste management practices by optimizing biogas generation and energy production while mitigating environmental impacts.
