The article discusses the significant issue of food waste globally and its negative impact on the environment, including contributing to greenhouse gas emissions. However, it presents a positive perspective on food waste as a potential sustainable resource for energy production, particularly through the production of bioH2. BioH2 production from food waste not only helps in reducing GHG emissions but also offers various benefits like creating job opportunities, decreasing waste disposal costs, and fostering a circular bioeconomy. Dark fermentation is highlighted as the most suitable method for bioH2 production from food waste due to its complex composition. The article also delves into the importance of inoculum pretreatment methods, such as heat shock, in enriching H2-producing bacteria and enhancing bioH2 yields. Overall, the article promotes the idea of turning food waste into a valuable energy source through bioH2 production, emphasizing its potential for sustainable development and environmental conservation.
