THE CONTEXT: India’s maize-based ethanol output has surged from 31 Cr L (0.8 MT maize) in 2022–23 to 484 Cr L (12.7 MT maize) in 2024–25, making maize the dominant ethanol feedstock at ~52% of the 837 Cr L total allocation. This 16-fold jump has reversed India’s position from a 3.7 MT maize exporter (2021–22) to a projected 1 MT importer (2024–25), sparking demands by the feed industry for duty-free and GM corn imports.
BACKGROUND: NATIONAL BIOFUEL POLICY TRAJECTORY (2003–2025):
| Milestone | Policy Decision | Features | Relevance to Feed vs. Fuel Debate |
|---|---|---|---|
| 2003 | Launch of EBP | 5% blending in select states | Initiated use of food grains for fuel |
| 2009 | National Policy on Biofuels | Targeted 20% blending by 2017; focused on non-food feedstocks | Avoided food grain diversion |
| 2018 | Revised Biofuel Policy | Allowed use of surplus food grains; set E20 target for 2030 | Opened doors for maize utilization |
| 2021 | Interest Subvention Scheme | Financial support for grain-based distilleries | Encouraged maize-based ethanol production |
| 2022 | Policy Amendment | Advanced E20 target to 2025-26; permitted maize use in surplus phase | Intensified feed vs. fuel concerns |
| 2024 | Achieved 10% blending | Ahead of schedule; increased maize demand | Highlighted maize's role in ethanol supply |
CURRENT STATUS (AS OF ETHANOL SUPPLY YEAR 2024–25)
-
- Maize Utilization: Approximately 12.7 million tonnes (MT) of maize contracted for ethanol production, up from 0.8 MT in 2022–23.
- Ethanol Production: Maize-based ethanol production reached 484 crore litres, indicating a significant surge.
- Price Impact: Maize prices escalated from ₹14,000–15,000 per tonne to ₹24,000–25,000 per tonne over four years.
LEGAL AND POLICY FRAMEWORK
-
- National Policy on Biofuels (2018): Permits use of surplus food grains for ethanol, emphasizing food security.
- Interest Subvention Scheme (2021): Provides financial incentives for establishing grain-based ethanol distilleries.
- Ethanol Blending Programme (EBP): Targets 20% blending by 2025, with maize as a key feedstock.
THE DDGS EFFECT: UNINTENDED CONSEQUENCES FOR SOYBEAN
-
- Distiller’s Dried Grains with Solubles (DDGS) is an essential byproduct of ethanol production from grains. This protein-rich material emerges as an alternative livestock feed ingredient, containing 28-30% protein content for maize-based DDGS and 45% for rice-based DDGS.
- The increased availability of DDGS has created downward pressure on soybean de-oiled cake (DOC) prices:
-
-
- DDGS from maize is sold at around ₹16,000-17,000 per tonne.
- DDGS from rice at ₹18,000-19,000 per tonne.
- In contrast, soybean DOC, with 45% protein, is priced at ₹31,000-32,000 per tonne.
-
GOVERNMENT INCENTIVES AND SUPPORT MECHANISMS
-
- The government has introduced various incentives to boost ethanol production, including:
- ₹9.72 per liter for ethanol derived from maize.
- ₹8.46 per liter for ethanol from damaged rice.
- ₹6.87 per liter for ethanol from C-heavy molasses.
- These incentives have significantly altered feedstock utilization patterns, with maize’s contribution to ethanol production rising to 36% in 2023-24 from virtually zero in 2021-22.
STAKEHOLDER IMPACT MATRIX: MAIZE-BASED ETHANOL BLENDING IN INDIA
| Stakeholder | Upside | Downside |
|---|---|---|
| Maize Growers | Farm-gate prices at or above MSP ₹2,225/qtl. Increased demand leading to potential income growth. | Price volatility due to market fluctuations. Rising input costs, especially fertilizers and water. |
| Poultry & Dairy Feeders | Access to cheaper Distillers Dried Grains with Soluble (DDGS) as a protein-rich feed alternative. | Core energy grain (maize) is becoming more expensive, eroding profit margins. Supply constraints affecting feed formulation. |
| Soybean Farmers | Potential for crop diversification incentives. | Soybean meal (DOC) prices are crashing below MSP ₹4,892/qtl due to reduced demand. Market oversupply leads to income instability. |
| Distilleries | Long-Term Offtake Agreements (LTOA) ensuring consistent demand. Interest subvention schemes reduce capital costs. | Policy risks if food security concerns lead to restrictions on grain-based ethanol. Dependence on government policies for feedstock allocation. |
| Oil Marketing Companies (OMCs) | Achieved 18.2% ethanol blending in December 2024, contributing to carbon emission reductions. | Escalating feedstock prices are jeopardizing cost parity with petrol. Supply chain uncertainties affecting blending targets. |
GLOBAL PERSPECTIVES:
-
- United States: Approximately 40% of maize is used for ethanol, leading to debates over food security.
- Brazil: Primarily uses sugarcane for ethanol; maize-based ethanol is region-specific.
- China: Initially promoted maize-based ethanol but reversed policies to prioritize food security.
THE CHALLENGES:
1. Rising Feed Costs and Food Inflation
-
- Maize prices have climbed by about 65 % in two years.
- Poultry and dairy farmers pass this cost to consumers, nudging up the WPI‑Food index.
- The bottom line is that maize costs more, and chicken, eggs, and milk are costlier.
2. The GM‑Maize Import Dilemma
-
- Industry wants duty-free genetically‑modified (GM) corn only for ethanol.
- Courts and environmental groups worry about biosafety and the lack of a fool‑proof tracking system.
- Policy tug‑of‑war: energy security vs. precautionary principle.
3. Water–Energy–Food Nexus
-
- Maize uses less water than paddy, but irrigation-dependent maize in dry zones can still drain aquifers.
- If rain-fed millet land shifts to maize, groundwater demand could jump sharply.
- India must balance crop shifts with local water realities.
4. International Trade Rules
-
- India already sits close to the WTO limit for price support on cereals.
- Subsidising maize for ethanol, while letting in duty-free imports, could invite WTO scrutiny.
- The challenge is to protect farmers without breaching trade commitments.
5. Winners and Losers Among Farmers
-
- Maize growers benefit from higher prices.
- Soybean farmers lose out as ethanol by‑product (DDGS) replaces soybean meal in animal feed, pushing soy prices down.
- Policy must even out these regional and crop-wise gains and pains.
6. Carbon Accounting & Slow 2G Roll‑out
-
- Grain-based ethanol emits roughly double the greenhouse gases of sugarcane-based ethanol.
- Only 2 of 12 planned second-generation (crop‑residue) plants are running.
- Without a faster 2G scale-up, India’s E20 target could clash with its net-zero promise.
7. Fragmented Data & Coordination Gaps
-
- No single, real-time dashboard tracks how much maize moves into ethanol.
- Multiple ministries handle pricing, acreage, biosafety, and trade—often in silos.
- A unified coordination cell and better data transparency are urgently needed.
THE WAY FORWARD:
1. “More Maize per Acre, not More Acres” — Launch Mission MAIZE‑4‑T
-
- Lift national yield from ~ 3 t/ha to 4 t/ha in 5 years through PPPP-made hybrids, CRISPR stress-tolerant lines, and drone-guided precision nutrition.
- Deploy PM‑PRANAM incentives and Pradhan Mantri Krishi Sinchai Yojana micro‑irrigation to nudge Eastern‑India farmers out of winter paddy into high‑yield maize.
2. “Ring‑Fence Food Security” — Create a Dynamic Feed‑Grain Ceiling + Strategic Maize Buffer
-
- Legally limit grain‑based ethanol to ≤ 25 % of annual supply; review the cap every quarter on a dashboard that shows cereal stocks, WPI‑Food and blending progress.
- USDA’s Biofuels‑Annual predicts a 6.35 BL ethanol output gap by 2025 unless grains are diverted aggressively; a safety‑valve reserve cushions such shocks.
3. “Turn Co‑products into Gold, not a Soy Crash” — BIS‑Certified DDGS 2.0 & a Livestock Feed Innovation Fund
-
- Fast‑track the BIS draft standard for Distillers Dried Grains with Solubles (DDGS) and list graded lots on e‑NAM; this prevents sub‑standard DDGS from under‑cutting soymeal.
- Support feed trials on high‑protein DDGS, sorghum‑rice blends, insect meal etc.—Nellore ram‑lamb study shows DDGS can raise daily weight‑gain by 9 %.
4. “Safe Corridor, Safe Gene” — A Conditional GM‑Maize Import Window with Full Traceability
-
- Use Section 3 of the Environment (Protection) Act + Rule 11 of 1989 Biosafety Rules to notify an industrial‑use‑only GM‑corn tariff quota; grain is bonded to distilleries, barred from food/feed channels.
- Tech Guardrails: Each shipment tagged with RFID seals and isotope‑ratio bar‑coding; annual audit by FSSAI.
5. “One Dashboard, One Command” — Create a Bio‑Fuel Coordination Cell & Open‑Data Portal
-
- A live site (MoPNG‑UPAg) plotting ethanol orders, feedstock draw, DDGS output, WPI‑Food, and MSP arrivals—updated fortnightly.
- Merge bio‑fuel files scattered across MoPNG, MoAFW, MoEF&CC, and MoCI into a single National Bio-Economy Coordination Cell; the Parliamentary Standing Committee on Petroleum (2024‑25) already mooted this idea.
THE CONCLUSION:
India’s “Four F” economy (Food‑Feed‑Fibre‑Fuel) is at an inflection point. The maize‑ethanol surge is a double‑edged sword—accelerating decarbonisation while stressing feed & oilseed sectors. A calibrated, science‑led, and systems‑thinking approach—anchored in yield enhancement, transparent markets, and next‑gen biofuels—can convert the present “fuel‑vs‑feed” trade‑off into a win‑win bio‑circular future, without compromising nutritional security.
