摘要
In recent years, anaerobic digestion (AD) has gained popularity as a practical method for generating clean energy and efficiently managing organic waste. However, the effectiveness of the reactor is compromised by the accumulation of ammonia, acids, and nutrients, leading to inhibition and instability. Because of its adaptability, biochar (BC) has sparked a substantial interest in biogas production and can be created by charring biomass and waste materials. Adding BC to the AD process could yield the following benefits: mitigating toxic inhibition, reducing the duration of the methanogenic lag phase, immobilising functional bacteria, and enhancing the rate of electron transfer between methanogenic and acetogenic microorganisms. Nonetheless, there remains to be more comprehensive knowledge regarding the multifaceted function of BC and its intricate mechanisms in the generation of biogas in AD. The research summarises scattered information from the literature on BC production from various feedstocks and factors affecting its characteristics. Additionally, a comprehensive analysis of the utilisation of BC as an additive within AD is presented here, emphasising how BC characteristics impact AD processes and how they effectively engage key challenges.
