21 October 2026 : Update regarding the Kitchen Waste Biogas plant - we are a family of 3 generating 1-3 kgs of biodegradable food kitchen waste per day - so how much gas can we possibly generate in 30 days - Here are the real life updates -
21 Sep–21 Oct 2026 = Calculation: 4.038 − 1.590 = 2.448 m³ over 30 days = 2,448 litres
Average per day 81.6 L/day
Average per hour 3.40 L/hour
This is approx 45 minutes of burn flame per day
But the electrical heater & pump being used to maintain biodigester temperature in winters are using 2 KWh per day or Rs 16 per day or Rs 480-500 per month
One problem adequate water hydration consistency via drip feed wasn't maintained during these months so with consistent hydration more gas production expected - hydration problem should get solved this October 2026 as a tap water extension for automated drip feeding has been planned.
The electricity bill consumption optimization is pending because 2 KWh is being used right now may be 1.5KWh can still give the required gas production -- this November 2026 weekly temperature hold & gas monitoring estimates should be able to tell
The 25 August 2026 digester slurry lab report also said it could not detect Molybedenum Cobalt Nickel heavy metals needed for digestion. Zinc Manganese Iron was also deficient. Since then Zinc Manganese Iron Molybedenum Cobalt Nickel have been fed but corresponding gas production increase not consistently observed.
The inconsistentcy could also be attributed to stable temperature control possible only since 10 Oct 2026.Hydration consistency is yet to be stabilized. Hydration consistency should be possible from October 2026
November 2026 experiment will tell us below what temperature does the gas production drop steeply - it simply crashes below a certain temperature day 1 - 30% less, day 2 50% less day 3 almost 70% less gas production but this exact minimum temperature to prevent a gas production crash is not yet known so higher electricity bills for now.
How much has been the investment you may ask in a kitchen waste biodigester plant ? My estimate is if a consultant were to do this kind of plant installation it would be around Rs 2 lakh.
So now you may ask what's the point in spending Rs 2 lakhs initially and Rs 500 per month heating bills just to get some 45 minutes of single cooktop burn flame ?
The digester can also generate 15-20 liters of liquid organic fertilizer which is to be diluted 10x so 200 litre of liquid plant fertilizer per day. We have seen liquid slurry organic fertilizer being sold for Rs 200 per liter.
The Rs 500 per month electricity bill was in winter months when ambient was 25C , if it's Summers heating bill would drop to zero.
You are also eliminating the need for centralized big expensive biodigester plants with your own mini biodigester plant processing own waste and generating own flame.
