If you’ve been looking for a way to cut down on your cooking gas bill, reduce your kitchen waste, and adopt a more eco-conscious lifestyle, setting up a biogas plant at home could be a game-changer.

When Union Petroleum Minister Hardeep Singh Puri recently announced a Rs 50 hike in LPG cylinder prices, it was a reminder of how vulnerable household budgets can be to fuel costs. But what if your everyday food scraps could help power your stove?

Biogas is a clean, renewable fuel created through the anaerobic digestion of organic waste. It not only offsets LPG use but also offers a sustainable way to manage kitchen waste — all from your own backyard.

What exactly is biogas?

Biogas is mainly a mix of methane (CH4) and carbon dioxide (CO2), produced when microorganisms break down organic matter in the absence of oxygen. This process also produces a nutrient-rich slurry known as digestate, which can be used as a natural fertiliser.

On a small scale, biogas is most commonly used for cooking. But depending on your setup, it can also power lights or generators.
