Researchers at the CSIR-Indian Institute of Chemical Technology have made significant strides in harnessing the potential of food waste for clean energy production. Lead scientist S. Venkata Mohan and his team have developed a breakthrough method to produce biohydrogen (bioH₂) from food waste, positioning it as a valuable clean energy source that aids in waste management and contributes to reducing carbon emissions. The study emphasizes the importance of enhancing hydrogen production efficiency while minimizing the environmental impact of biogas generation. By utilizing an upflow reactor and continuous fermentation process, the researchers have achieved stability in conditions, boosting fermentation efficiency and hydrogen production with minimal energy consumption. This sustainable approach not only addresses waste management challenges but also aligns with global efforts towards renewable energy adoption. Furthermore, the team's innovative project on carbon-negative gas electro-fermentation showcases a method to convert carbon dioxide into ethanol and acetic acid, essential chemicals for various industries. The process, which eliminates the need for external hydrogen, is lauded for its sustainability, energy efficiency, and cost-effectiveness, contributing to higher yields of acetic acid and ethanol while removing CO₂ equivalent emissions from the environment. The research findings highlight the immense potential of transforming food waste into valuable resources, emphasizing the role of biohydrogen and carbon-negative gas electro-fermentation in advancing sustainability goals. These breakthroughs not only offer solutions to waste management and clean energy needs but also pave the way for more eco-friendly and efficient energy systems.
