Adani Group is quietly building a new business far removed from its ports, airports and energy operations — selling organic fertilizers to farmers. Through its ‘Harit Amrit’ brand, the conglomerate has expanded sales across Uttar Pradesh, Madhya Pradesh and Gujarat, signalling its entry into India’s fast-growing organic farm inputs market as its compressed biogas (CBG) business scales up.
The fertilizer business has gathered pace over the past year. ATBL first launched the Harit Amrit brand in FY25 while selling more than 2,000 tonnes of organic fertilizer. A year later, the company expanded the brand into three States, with fertilizer sales more than doubling to over 4,575 tonnes in FY26. During the same period, CBG sales also rose sharply to 1,654 tonnes from 730 tonnes, according to the company’s FY26 annual report, reflecting the ramp-up of its biomass operations.
The business, housed under Adani TotalEnergies Biomass Ltd (ATBL), a wholly owned subsidiary of Adani Total Gas Ltd, is built around an integrated waste-to-energy model. Agricultural residue, cattle dung and, eventually, municipal solid waste are processed using anaerobic digestion technology to produce compressed biogas, while the residual digestate is converted into branded organic fertilizer sold under the Harit Amrit label.
multi faceted project
At the heart of the business is the company’s Barsana project in Uttar Pradesh, which is being developed as India’s largest agri-waste-based compressed biogas facility. The project is designed to address multiple challenges simultaneously — reducing stubble burning, generating renewable transport fuel, producing organic fertilizer and creating value from agricultural waste that would otherwise be discarded or burnt.
The first phase of the Barsana plant is now operational and currently processes around 115 tonnes of agricultural waste and cattle dung per day. The facility has achieved peak CBG production of 7.5 tonnes per day, with the company expecting output to increase to around 11 tonnes per day during FY27 as operations stabilise. When fully commissioned, the over ₹200-crore project will process 600 tonnes of feedstock every day, generating more than 42 tonnes of compressed biogas and 217 tonnes of organic fertilizer daily, making it India’s largest agri-waste-based CBG plant.
Adani is also expanding the biomass platform beyond agricultural waste. ATBL has secured municipal solid waste-to-CBG projects in Ahmedabad and Rajkot, with a combined feedstock processing capacity of 750 tonnes per day, extending its waste-to-energy model to urban waste streams. The company has also begun building downstream infrastructure for renewable fuel. During FY26, it commissioned its first dealer-owned dealer-operated (DODO) CBG dispensing station, providing a retail outlet for the biogas produced at its facilities.
The business aligns with the Centre’s Sustainable Alternative Towards Affordable Transportation (SATAT) programme, which aims to promote compressed biogas production and support the government’s target of 5 per cent CBG blending. The company is also exploring carbon credit opportunities through projects registered under the Verra Verified Carbon Standard and the Gold Standard for the Global Goals.
