OIL Green Energy Limited (OGEL), a wholly owned subsidiary of Maharatna CPSE Oil India Limited (OIL), has signed Memoranda of Understanding (MoUs) with the municipal authorities of Gurugram, Faridabad, Hisar and Ambala for the development of four integrated Compressed Biogas (CBG) and Waste-to-Energy projects in Haryana. The MoUs were signed in the presence of Haryana Chief Minister Nayab Singh Saini, along with senior ministers, Members of Parliament and senior officials from the Government of Haryana, OIL and OGEL.
The proposed projects will be developed across four municipal clusters, with processing capacities of 2,000 tonnes per day (TPD) in Gurugram, 1,600 TPD in Faridabad, 900 TPD in Ambala and 500 TPD in Hisar. Collectively, the facilities are designed to scientifically process approximately 5,000 tonnes of municipal solid waste every day.
Once operational, the four projects are expected to produce around 70–75 TPD of Compressed Biogas and approximately 50 MW of green power. The projects will follow an integrated waste-processing and resource-recovery model. Municipal solid waste will first undergo scientific pre-processing and segregation to recover usable materials and direct different waste streams towards appropriate applications. Recyclable materials will be recovered for further use, while the wet and biodegradable fraction will be processed to produce CBG. The non-recyclable dry fraction will be used as feedstock for Waste-to-Energy facilities to generate electricity.
The approach is intended to increase material recovery, improve energy utilisation from non-recyclable waste and reduce the volume of municipal waste sent to landfills. By converting different waste fractions into CBG and green electricity, the projects will create additional avenues for resource recovery while addressing municipal waste-management requirements.
The initiative supports Haryana’s efforts to strengthen scientific and sustainable municipal solid-waste management. It also contributes to national priorities relating to Waste-to-Wealth, the circular economy and the transition towards cleaner sources of energy. The projects are aligned with the Government of India’s GOBARdhan – National Circular Bioenergy Scheme 2026, which aims to promote scientific management of organic waste and accelerate the conversion of waste into CBG and other forms of clean energy.
For OIL, the agreements represent an expansion of its low-carbon energy portfolio through OGEL and strengthen its focus on integrated waste-to-clean-energy projects at scale. The collaboration with the four Haryana municipalities is expected to create a framework for converting municipal waste into useful resources while supporting cleaner and more sustainable urban infrastructure.
