Indian automotive giant Maruti Suzuki has announced two new biogas projects as part of a broader push to reduce fossil fuel dependence across its manufacturing operations.
The company will commission a 10 tonnes per day (TPD) biogas plant at its Kharkhoda facility within the current financial year (FY 2026-27), while also completing an expansion of its existing plant at Manesar — increasing output there from 0.2 TPD to 0.7 TPD.
The Kharkhoda plant is expected to meet approximately 20% of the facility's total gas requirement and mitigate an estimated 9,490 tonnes of CO₂ annually. The expanded Manesar plant, which came online earlier this month, will generate around 3.6 lakh standard cubic metres of biogas per year, avoiding an estimated 664 tonnes of CO₂ emissions.
The Manesar facility uses food waste, Napier grass and paddy straw as feedstock — with provision to supplement output using cattle dung — and employs anaerobic digestion technology to convert agricultural waste into raw biogas. The gas feeds into paint shop heating and canteen operations, while fermented organic manure (FOM) produced as a by-product is used for horticulture or returned to the agricultural supply chain.
Maruti Suzuki has earmarked INR 150 crore for the two projects and plans to invest INR 925 crore in green energy initiatives overall by FY 2030-31. The company's installed solar capacity currently stands at 79 MWp, with a target of 319 MWp by the same date.
The announcements were made on World Environment Day (5 June). Managing Director and CEO Hisashi Takeuchi said the projects reflected the company's commitment to reducing fossil fuel consumption and oil import dependence at a time of global energy uncertainty.
Maruti Suzuki recently replaced natural gas with biogas to cover around 10% of energy requirements at its Hansalpur facility, following LNG supply constraints.
