Biofuels in India: The Big Energy Opportunity Everyone Missed | Govindraj Ethiraj

ELI5/TLDR

India imports almost all its oil and half its gas, and burns through 700 million tons of crop waste a year that mostly rots in fields or gets set on fire. If you could collect even a fraction of that waste, compress it, and ship it to power plants and gas refineries, it could cover roughly one-fifth of India’s energy needs. The catch is that nobody has built the supply chain — coal took 150 years to get reliable, and India is trying to do this in five. Suhas Baxi runs a Pune-based startup, Biofuels Circle, that’s trying to be the Uber for crop residue: an app, a network of tractor drivers, and 800 villages so far.

The Full Story

The setup nobody is solving

India is in an energy hole. Roughly 85-90% of its crude oil is imported. More than 50% of its gas. Industrial users are getting their gas curtailed; LPG cylinders are getting tight. Meanwhile, every year Indian farms produce about 700 million metric tons of leftover plant matter — stalks, stubble, husks. Cattle eat some of it. Roughly 200 million tons just sits there, scattered across millions of acres.

If you could capture all of it and turn it into fuel, biofuels could cover about 18% of India’s energy demand. Right now they cover about 1-2%. The technology exists. The willingness exists. What doesn’t exist is the boring stuff in the middle — the trucks, the depots, the schedules, the bales.

“Coal took 150 years to create a supply chain which is reliable at scale. We are wanting to create this supply chain in 3 to 5 years time.”

Three forms, three different problems

Biofuels come in three flavours, and each is at a different point on the journey.

Solids — basically dried, compacted crop waste shaped into pellets or briquettes. These replace coal in industrial boilers (think paint factories, textile mills) and increasingly in thermal power plants. The technology is mature; it’s a commercial decision now. The government has mandated thermal plants to mix 5-20% biomass into their coal. Baxi thinks the realistic timeline for hitting 5% across the country is 2030, not the official 2027.

Liquids — mostly ethanol blended into petrol. India is now at E20, meaning 20% of what goes into your fuel tank is ethanol. This has touched the most lives because it’s at the pump, but the supply side is concentrated — sugar mills and large institutional players, not millions of farmers.

Gases — compressed biogas (CBG). This is the sleeper hit. CBG is chemically identical to the natural gas in your kitchen stove. The user wouldn’t notice the switch. The government’s Satat policy aims for 5,000 CBG plants. About 150 are running. Reliance and Indian Oil are building more. Baxi thinks CBG will be the single biggest fossil-to-green transition India makes.

Why CBG is also a fertilizer story

Here’s a detail worth holding on to. When you feed biomass into a CBG digester, only 12-15% of the mass becomes gas. The other 85% comes out the other end as fermented organic manure. That goes back to the soil — adding carbon, holding water, complementing chemical fertilizers.

So a CBG plant is not just an energy facility. It’s the centre of a small circular economy: farms send waste in, gas goes to the city, fertilizer goes back to the farms.

The real bottleneck is distance

The problem with crop waste is that it’s bulky and light. Trying to ship loose stubble across India is like trying to ship air. So the entire game is about compacting it close to the source.

Step one happens in the field: a baler runs through right after harvest, packs the stubble into dense bales. Farmers have a 15-30 day window between harvests (kharif and rabi) to clear the land. Miss it and the field can’t be sown.

Step two is a local depot — a 10-acre open area within 10-15 km of about 2,000 farmers. Bales pile up here. From the depot, the dense bales can travel further to a processing plant.

“I think the biggest enemy of biomass and solid bio residue is distance.”

This is why CBG plants have to be small and many — you can’t haul biomass 500 km, but you can haul it 50.

What the math looks like

To replace just 5% of India’s coal in thermal power, you need 50 million tons of biomass a year. That comes from 25 million acres of farmland. That involves about 10 million farmers across roughly 50,000 villages. Each cluster needs a depot, machinery, trained tractor drivers, a schedule, and a payment system.

Baxi’s company, Biofuels Circle, has reached 800 villages in three years. Even doubling every year, they’d need 5-6 more years to hit 50,000. Other companies will obviously join. He compares the moment to Amul — the milk cooperative model that turned millions of small dairy farmers into a national supply chain.

The Uber-for-stubble model

The clever part of Biofuels Circle isn’t the hardware. It’s the orchestration. A farmer opens a WhatsApp chatbot, books a cleaning slot, and on the appointed day a tractor driver shows up with a baler, clears the field, and the farmer gets paid via UPI the same evening.

Each cluster has 10-15 km radius, ~2,000 farmers, ~50 tractor drivers (10 year-round, 40 seasonal). The tractors already exist in rural areas — they sit idle after harvest. Biofuels Circle invests in the specialized baling machines and runs the software layer that schedules, routes, pays, and verifies fuel use.

“Participation should be as easy as for coming for this to the studio I called an Uber to reach my house at 9:45.”

In a year they moved 700,000 tons of biomass. The total addressable mountain is 235 million tons. A drop, but a drop that proves the model.

Where the gap really is

Baxi is unusually clear-eyed about why this isn’t moving faster. The big oil companies want to invest. The technology providers (Thermax, Praj) have the kit. NTPC is willing to mix biomass into coal. Government policy exists.

The missing piece is what economists would call market infrastructure — the boring layer that makes sure the right quality of biomass shows up at the right plant on the right day at the right price. Solar took off because once you install a panel, the sun shows up reliably. Biomass needs an entire human supply chain to show up reliably.

The founder origin story

Baxi spent 1999-2006 running the India business of Triple Point Technology, an American software company that sold trading and risk management software to oil and gas firms. He watched how Morgan Stanley owned oil storage assets around the world — how the energy business is really a logistics-and-storage business with a fuel coat of paint. When he later asked why bioenergy hadn’t taken off, the answer was obvious to him: nobody was being paid to build storage and ecosystem. So he built one.

Key Takeaways

India produces ~700 million tons of agricultural residue annually; ~200 million tons of it is currently waste, scattered across fields.
Biofuels could in principle cover ~18% of India’s energy demand. Today they cover 1-2%.
The energy import dependency is brutal: ~85-90% of crude oil and ~50% of gas are imported.
Biofuels split into three categories at different maturity: solids (mature, just commercial), liquids/ethanol (institutional, scaled via E20 mandate), gases/CBG (early, highest upside).
Biomass calorific value is 70-80% of coal’s — usable but requires fuel handling upgrades and sometimes boiler refurbishment.
The government has mandated 5-20% biomass blending in thermal coal plants. Realistic timeline: 2030, not the stated 2027.
CBG is chemically identical to natural gas — same molecule, different source. End users wouldn’t notice the swap.
85% of biomass fed into a CBG digester comes out as fermented organic manure, returning carbon and nutrients to the soil. CBG plants are circular economy nodes, not just energy plants.
The Satat policy targets 5,000 CBG plants in India; ~150 are operational, ~500 more in commissioning.
Distance is the killer: biomass is light and bulky. Plants must be small, many, and within ~50 km of feedstock.
A viable cluster: 10-15 km radius, 2,000 farmers, 5,000 acres, ~10,000 tons of biomass per season, one 10-acre “biomass bank” depot.
Baling must finish in the 15-30 day window between rabi and kharif crop seasons. Industrial-grade rural logistics, not a side hustle.
Existing tractor capacity in rural India is idle post-harvest. Tapping it requires no new heavy capex, just the specialized baler attachments and a scheduling layer.
Technology providers like Thermax and Praj have the equipment. Reliance, Indian Oil, NTPC have the demand. The missing layer is supply chain orchestration.
Biofuels Circle has reached 800 villages, 200,000 farmers, and moved 700,000 tons in 3 years. Hitting 50,000 villages would take 5-6 more years at their planned doubling pace.
The right mental model is Amul: a national cooperative-style movement, not a single company solving it end to end.

Claude’s Take

This is a useful, slightly under-polished interview. The guest is clearly smart and operator-minded, not a hype merchant. He keeps coming back to logistics and unit economics rather than carbon credits or ESG slogans, which is the right instinct. The Amul comparison is the strongest analogy in the conversation — both are problems of aggregating millions of small producers into something industrial-scale.

The 18% figure for biofuels’ share of India’s energy is the kind of number that should make you pause. Even half of that would meaningfully dent India’s import bill. The timelines, though, deserve scepticism. Baxi himself slips the 2027 government target to 2030, and his own company’s village count would take 5-6 years to scale 60x. The pattern in Indian infrastructure is usually that things take 1.5-2x the announced timeline, especially when they require coordinating across millions of farmers and a hundred-plus state and central agencies.

CBG is the most interesting bet in the conversation. The fact that it slots into existing natural gas pipelines without consumer-side change is a real edge. Solar and wind needed grid changes; ethanol needed engine compatibility debates. CBG is just methane. The 85% residue becoming fertilizer is the kind of two-for-one that policymakers should be louder about.

What’s missing from the interview is honest pricing data. Is biomass actually cost-competitive with coal at the boiler, or only with subsidies? What’s the IRR on a CBG plant without policy floors? Baxi gestures at this (“policy allows a particular floor which gives reasonably good IRR”) but doesn’t quantify. That’s the question that decides whether this is a 5-year story or a 25-year story.

Score 7. Solid signal, well-structured argument, real operator giving real numbers. Loses a point for the missing economics layer and another half for the slightly promotional framing in the back half.
