Maruti Suzuki is strengthening its sustainability roadmap with major investments in green energy, focusing on biogas and solar power to reduce fossil fuel dependence across its manufacturing facilities.
Maruti Suzuki India Limited has taken a significant step toward sustainable industrial practices by announcing an expansion of its green energy initiatives. The company plans to invest ₹925 crore by the financial year 2030-31 to enhance its renewable energy infrastructure. This move aligns with its long-term strategy to reduce reliance on fossil fuels and lower carbon emissions across its manufacturing network.
As part of this initiative, the company has unveiled two key biogas projects that will play a crucial role in transforming its energy consumption patterns. These projects reflect a growing trend among automotive manufacturers to adopt environmentally friendly solutions while maintaining operational efficiency.
One of the immediate developments under this initiative is the expansion of the biogas plant at Maruti Suzuki’s Manesar facility. The plant’s capacity has been increased from 0.2 tonnes per day (TPD) to 0.7 TPD, significantly boosting its production capabilities.
With this upgrade, the plant is expected to generate approximately 3.6 lakh standard cubic meters of biogas annually. This increase in output will contribute to an estimated reduction of 664 tonnes of carbon dioxide emissions each year, highlighting the environmental benefits of the project.
The Manesar biogas plant utilizes a variety of organic waste materials, including food waste, Napier grass, and paddy straw. Through anaerobic digestion technology, these materials are converted into biogas, which is then used in critical operations such as paint shop heating and canteen services.
In addition to biogas production, the plant generates Fermented Organic Manure (FOM) as a byproduct. This nutrient-rich material is used for internal horticulture purposes and is also distributed to the agricultural sector, promoting a circular economy approach.
The second and more substantial project involves the development of a new biogas plant at Maruti Suzuki’s Kharkhoda facility. With a planned capacity of 10 TPD, this plant is expected to become a cornerstone of the company’s renewable energy infrastructure.
Scheduled for commissioning in the financial year 2026-27, the Kharkhoda plant is projected to significantly reduce carbon emissions by approximately 9,490 tonnes annually. Once fully operational, it will meet around 20 per cent of the facility’s total gas requirements, marking a major step toward energy self-sufficiency.
The scale of this project demonstrates Maruti Suzuki’s commitment to integrating large-scale renewable energy solutions into its manufacturing processes.
The combined investment in the Manesar and Kharkhoda biogas projects is estimated at ₹150 crore. These projects form part of the company’s broader ₹925 crore green energy investment plan, which encompasses various renewable energy initiatives.
Beyond biogas, Maruti Suzuki is also focusing on expanding its solar power capabilities. The company currently has an installed solar capacity of 79 megawatt-peak (MWp) and aims to increase this to 319 MWp by FY31. This substantial expansion will further reduce dependence on conventional energy sources and enhance the company’s sustainability credentials.
Maruti Suzuki’s green energy journey has already shown promising results at its Hansalpur facility. At this plant, biogas has successfully replaced natural gas for approximately 10 per cent of the facility’s energy requirements.
This transition has not only reduced carbon emissions but also ensured operational continuity during periods of liquefied natural gas (LNG) supply disruptions. The success at Hansalpur serves as a model for other facilities and reinforces the viability of biogas as a reliable energy source.
Biogas is emerging as a key component of sustainable industrial operations. By converting organic waste into usable energy, companies can reduce waste disposal challenges while generating clean fuel. This dual benefit makes biogas an attractive solution for industries seeking to minimize their environmental impact.
For Maruti Suzuki, the integration of biogas into its manufacturing processes represents a strategic move to align with global sustainability goals while maintaining cost efficiency.
The company’s use of agricultural residues such as paddy straw and Napier grass highlights its commitment to supporting rural ecosystems. By sourcing feedstock from agricultural waste, Maruti Suzuki contributes to reducing crop burning, a major environmental concern in India.
Furthermore, the production of fermented organic manure as a byproduct promotes soil health and agricultural productivity, creating a positive feedback loop between industrial and agricultural sectors.
Maruti Suzuki’s ₹925 crore investment plan reflects a long-term vision of achieving significant carbon footprint reduction. By diversifying its energy sources and investing in renewable technologies, the company aims to create a resilient and sustainable manufacturing ecosystem.
The integration of biogas and solar power is expected to play a crucial role in achieving these objectives, enabling the company to meet both regulatory requirements and global environmental standards.
Conclusion: Driving Sustainable Growth in the Auto Sector
Maruti Suzuki’s expansion of biogas projects and its broader green energy investments mark a significant milestone in India’s industrial sustainability journey. By adopting innovative energy solutions and scaling up renewable infrastructure, the company is setting an example for the automotive sector.
As industries worldwide move toward greener practices, Maruti Suzuki’s initiatives demonstrate how strategic investments and technological innovation can drive both environmental and economic benefits.
