Praj Industries is expanding beyond its traditional ethanol-engineering business as slower domestic greenfield activity, customer funding constraints and excess capacity weigh on new project execution. The Pune-based company is increasingly pursuing opportunities in hyperscale data centres, semiconductor water treatment and emerging biofuel technologies, according to a report by The Economic Times.
The diversification comes as India’s ethanol market enters a different phase following the achievement of the 20% ethanol-blending target. Government data shows that ethanol blending reached 20% in 2025-26, while national production capacity has expanded substantially, creating a more challenging environment for new distillery investments.
Praj’s domestic first-generation ethanol business is experiencing a slowdown in greenfield projects, according to a senior company official cited by The Economic Times. New enquiries are reportedly concentrated in ethanol-deficit markets, including Tamil Nadu and Assam.
The official also indicated that the subdued project environment could persist until there is greater policy visibility around higher ethanol-blending mandates. Funding constraints among customers are meanwhile delaying projects already included in Praj’s order book, while excess capacity is affecting project execution and the conversion of orders into revenue.
Praj enters hyperscale data-centre infrastructure
One of the clearest new opportunities for Praj is the data-centre market.
Praj has secured a global supply agreement through its GenX business for modular infrastructure for hyperscale data centres. The agreement carries a minimum business commitment of about US$50 million over 2.5 years, according to The Economic Times.
The move builds on an opportunity that Praj had already identified in its FY2025-26 business outlook.
Praj’s modularisation and engineering capabilities therefore provide a route into a market that is structurally different from conventional ethanol-plant engineering.
Semiconductor water treatment adds another diversification route
Water and wastewater treatment is another area where Praj is positioned to benefit from industrial investment outside biofuels.
The company already provides industrial effluent treatment, water recycling and zero-liquid-discharge solutions. Its wastewater business serves sectors including steel, power, chemicals, fertilisers, food and beverages, textiles, pharmaceuticals and other industries.
Praj has also identified semiconductor manufacturing as an emerging opportunity for its high-purity water and zero-liquid-discharge businesses.
Diversification is already visible in Praj’s order mix
Praj’s recent disclosures indicate that the company is not relying solely on new ethanol capacity for future growth.
Its FY2025-26 results materials highlighted opportunities and orders in areas including carbon capture, industrial water treatment, data centres, precision fermentation and advanced manufacturing. The company also reported a significant order for integrated effluent treatment, water recycling and zero-liquid-discharge solutions from a major metals company.
Praj’s investor presentation also shows that its business extends beyond bioenergy into engineering and high-purity water. As of Q3 FY2025-26, the company reported an order book of ₹44.91 billion, while bioenergy accounted for 71% of revenue in the first nine months of FY2025-26, with engineering contributing 18% and high-purity operations 11%.
That mix indicates that bioenergy remains the dominant business while engineering and water-related activities provide diversification channels.
Bioenergy Business Analysis
Praj’s diversification reflects a broader transition in the Indian ethanol-equipment market: after several years of capacity expansion, engineering companies increasingly need to find growth in adjacent industrial and energy-transition applications.
The company’s move into hyperscale data-centre infrastructure and semiconductor-related water treatment is notable because both markets can draw on capabilities Praj already possesses in modular engineering, process systems, water treatment and project execution. Its reported US$50 million minimum commitment for the data-centre agreement provides a tangible commercial entry point rather than merely a stated diversification objective.
At the same time, the reported slowdown in domestic 1G ethanol projects should not be interpreted as a structural decline of India’s biofuel sector. E20 has established a large and continuing ethanol demand base, while advanced biofuels, SAF and other bioeconomy applications remain areas of technology development. The key uncertainty for new conventional ethanol capacity is the policy and demand environment beyond the current 20% blending level.
For Praj, the strategic question is therefore less about replacing bioenergy and more about reducing dependence on a single investment cycle. Success in data centres, semiconductors, high-purity water and advanced biofuels could broaden its engineering revenue base while allowing the company to retain its established position in bioenergy.
