Examine how the diversion of sugarcane/sugar to ethanol production has reshaped the economics of India's sugar industry.

India is the world's largest producer and consumer of sugar and its second-largest exporter [1], yet the industry long suffered chronic surplus, depressed mill-gate prices and mounting cane arrears. Permitting diversion of cane juice and B-heavy molasses to ethanol since 2018 has restructured this economics — though it has not made the sector market-independent.

From distress disposal to planned diversion

• Sugar diverted to ethanol rose from 3.37 LMT (2018-19) to 36 LMT (2021-22) [2], converting an unsellable surplus into a domestically absorbed product.
• This reduced reliance on subsidised exports and buffer stocks, letting supply be balanced before prices collapse rather than after.

Revenue diversification and liquidity

• Ethanol sales earned mills and distilleries about ₹18,000 crore in 2021-22 [2], creating a second revenue stream insulated from sugar price cycles.
• Improved cash flow enabled near-complete clearance of cane dues without central subsidy [2], directly strengthening farmer incomes.

A shift in the price architecture

• Assured offtake by oil marketing companies at administered ethanol prices gives mills a guaranteed-demand product, complementing the Minimum Selling Price of sugar (₹29/kg in 2018, raised to ₹31/kg in 2019) [3] as a floor.
• Mills have become dual-product firms, with capital increasingly flowing into distillery capacity rather than sugar capacity alone.

Persisting constraints

• Profitability remains policy-determined: diversion caps, ethanol pricing and consumer-side tools such as stock holding limits on dealers [4] still drive outcomes, as reflected in the recent ~20% fall in ex-mill prices [5].
• The Sugar (Control) Order, 2025 has brought by-products, including ethanol, within the regulatory net [6], signalling deeper State involvement, not less.

Ethanol diversion has thus turned a surplus-burdened, subsidy-dependent industry into a partially self-financing energy-cum-food enterprise. Sustaining this requires feedstock diversification beyond cane, water-use rationalisation and stable long-term ethanol pricing, so that the Ethanol Blended Petrol Programme advances both farmer prosperity and energy security.
