Researchers at the CSIR–Central Leather Research Institute (CSIR-CLRI) in Chennai have developed a new approach to increasing biogas production by using banana and cauliflower waste, while also helping to reduce carbon dioxide emissions. The research team created a low-cost biogas enhancement method that incorporates banana peels and cauliflower stems into food-waste digesters. This acidic environment restricts the activity of methane-producing microbes, which in turn reduces gas production. The inclusion of banana peels and cauliflower stems helps counter this effect by naturally moderating acidity and maintaining a more stable digestion process. Food waste sourced from restaurants and a university mess hall was mixed with either banana peel waste or cauliflower stem waste in a 70:30 ratio.
