The Next Phase Of Indias Fuel Blending Policy Turning Waste Into Wealth The Daily Brief 479

TITLE: The next phase of India’s fuel-blending policy | Turning waste into wealth | The Daily Brief #479 CHANNEL: Markets by Zerodha DATE: 2026-06-04 ---TRANSCRIPT--- In today’s episode, we’ll break down two important stories. First, we’ll talk about India’s fuel blending machine entering its next costly phase and then we’ll talk about India’s wet waste problem being a $50 billion opportunity. Welcome back to the daily brief by Zeroda where we cut through the noise to help you understand what’s actually happening in the most important stories from business and markets. I am your host Axara and today is Thursday 4th June. Coming to the first story. So on 29th May, the road transport secretary of India V. Um Shankr said that India is likely to bring a mandate for blending a bofuel named isobutinol into diesel later this year. A week before that, the Bureau of Indian Standards had notified fuel specifications for E22, E25, E27 and E30 petrol blends, all of which contain higher proportions of ethanol than the E20 that India currently uses. And then later this week, Marati Suzuki is expected to launch India’s first mass market flex fuel car that runs on any levels of ethanol, be it E20 or E00. All of these announcements took place within a span of a week. Some of these moves may have been in the works for years, but there’s also an unmistakable sense of urgency involved. Now, we’ve covered India’s ethanol blending program before. It dates back to a national policy on bofuels in 2018, and that policy has achieved a key milestone of 20% ethanol or E20 in all petrol-based vehicles in an attempt to reduce our oil import bill. So, the straight of hormones crisis to which India has found itself acutely exposed speeded up some of those timelines. Petroleum Minister Hardep Singh Puri told Parliament in March that the disruption was unlike anything seen in modern energy history. It is in that context that bofuels are no longer just a climate or farm policy. They are being framed as a strategic hedge to preserve independence. However, the ethanol blending program has proven to be a very costly affair on multiple fronts. While those costs are yet to go away, India is seriously considering what comes after E20. This story attempts to make a cohesive narrative out of all of these announcements. So let’s dive in. India went from 1.5% ethanol blending in 2014 to 20% by November 2025. From April 2026, E20 is mandatory nationwide. Now over the last decade, as per government statistics, the program has substituted around 245 lakh metric tons of crude oil. And as far as these objectives matter, this has been a successful industrial policy. But the incentive machine that made it possible doesn’t have an off switch. See, starting in 2018, the center rolled out an interestion scheme where the government bore up to 6% peranom or approximately 50% of the interest rate, whichever was lower, on loans taken to build new ethanol distilleries or expand existing ones. Over 1,100 sugar mills received in principal approval. oil marketing companies or OMC’s like IOCL, BPCL signed long-term procurement agreements at government fixed prices. So investors saw three things at once. Subsidized capital, a captive buyer and a government target E20 by 2025 that implied demand would keep pricing. Everyone build at once. However, this has now caused over capacity in ethanol. India has now installed ethanol capacity of roughly 2,000 cr L against E20 demand of only about 1,100 cr L. Another 400 cr L of capacity is expected to come online by FY27. OMC’s are absorbing only about 60% of the ethanol being offered to them and Care Edge expects utilization to stay at 65 to 75% for the next 3 years. So in other words, the government aggressively expanded supply but without adequate support on the demand side. Part of this also stems from government fixed price floors for farmers. Now this surplus is the engine driving everything that follows. The policy system has to find new demand or watch those investments go bad. Meanwhile, the procurement agreements are still in place and the subsidies and administered prices still apply. That will certainly keep capacity coming. So the most intuitive answer to the surplus problem is to put more ethanol into fuel. That’s what the new ethanol standards launched by BIS solve. At the same time, the government is pushing flex fuel vehicles, cars and motorcycles that can run on E85 or 85% ethanol or even E00 pure ethanol. The central motor vehicle rules have been amended to recognize these fuels. And E00 is now part of official testing and certification standards in April 2026. And Indian oil already sells E00 at 183 retail outlets. But how meaningful is this really? The practical constraints are significant. E85, for instance, delivers nearly 30% worse mileage than petrol simply because ethanol has less energy per liter, about 2/3 of gasoline’s calorific value. Additionally, a flex fuel upgrade adds an estimated rupees 40,000 to 50,000 to a vehicle’s price. Maruti’s own executive Rahul Bati has cautioned that flex fuel volumes are unlikely to be significant in the near term due to limited models and limited pump availability. This is a chicken and egg problem. OEMs won’t build flex fuel cars without fuel at pumps and OMC’s won’t invest in E85 or E00 pumps without enough cars on the road. Even if India raises ethanol blending from E20 to E30, the incremental energy security gain diminishes with each step up. As per Niti Aayog’s own planning assumptions, E20 requires 1,16 cr L of ethanol while E30 would require above 1520 cr L. And those extra 500 cr L of ethanol displace only about 339 cr L of petrol on an energy equivalent basis. Naturally, these crude numbers assume there won’t be technological innovation to ensure higher ethanol blends work. But even then, innovation also requires a lot of risk capital and OEMs will be hesitant to spend huge amounts of money on such innovation without assured supply, especially when other proven technologies like EVs and CNG already exist. More importantly, petrol is not where India’s real oil vulnerability lies. We consume more than double the diesel compared to petrol. Trucks, buses, agricultural equipment, railways, gen sets, all of them run on diesel. A petrol blending strategy. no matter how ambitious can only address a fraction of India’s crude oil dependence. Now, India did try to do for diesel what it did for petrol. The government ran trials blending ethanol into diesel and failed. And the reasons for this are entirely technical. See, diesel engines work on compression ignition, which means the fuel air mixture ignites from being compressed, not from a spark plug. So this requires a high Cain number which is a measure of how easily a fuel ignites under compression. Ethanol has a very low Ca number. So when you put it in a diesel engine, you get incomplete combustion, engine knocking and power loss. Moreover, ethanol and diesel just don’t mix. Ethanol absorbs moisture quite easily which is not good for diesel ignition. So the government pivoted to isobutinol. Just like ethanol, isobutinol is also an alcohol. Both can be made from the same raw materials like sugarcane, molasses and maze. They share much of the core infrastructure but they are not the same molecule and are produced through different biological processes. So ethanol is made through the glycolysis fermentation pathway that yeast has been performing for ages. But no organism in nature evolved to produce isobutinol in large quantities. So to make useful quantities of isobutinol, you need genetically engineered organisms. Isobutinol is better in every way that ethanol isn’t. It has higher energy density than ethanol, mixes with diesel much better, and doesn’t turn into vapor easily under pressure, which is exactly what a compression ignition engine needs. Now, the industrial infrastructure for this is starting to take shape. The automotive research association of India or ARI is testing 10% isobutinol diesel blends and BPCL is involved in the validation. In fact, PR Industries, India’s largest ethanol plant EPC company, has a partnership with Jivo, a US biotech firm that developed a proprietary yeast capable of fermenting sugars into isobutinol instead of ethanol. They’re setting up a demonstration scale fermentation module at a sugar mill in Maharashtra. Now as per the Indian sugar mills association a 150 kilo L or KL per day ethanol refinery can pivot with modest investment to produce 125 kilo ethanol plus 20 kl isobutinol each day. The existing surplus capacity becomes the foundation and this is where the story needs a reality check. So the pitch that isobbutinol is a straightforward bolt-on to India’s existing ethanol infrastructure is appealing but it understates the difficulty considerably. Now what India is attempting with isobutinol doesn’t have a powerful precedent. One of the key inspirations for our bofuels policy was Brazil. The most successful case of an ethanol industrial policy and a pioneer in flex fuel vehicles. But there’s no Brazil for isobutinol. No country has commercialized isobutinol diesel blending at scale yet. The biggest bottleneck to that is obviously biological. So in wild type yeast which generates ethanol at scale, isobutinol is a byproduct produced in very minimal quantities. To make useful amounts, you need engineered microbes with the isobutinol pathway bolted onto their metabolism. But unfortunately isobutinol itself is toxic to the very organisms that produce it. At concentrations of just 1 to 2% in the fermentation broth, isobutinol starts killing the microbes. Compare this to ethanol where industrial yeast happily tolerates concentrations of 15 to 20%. Now, what this means in practice is that with isobutinol, you get a far more diluted broth with lots of unwanted byproducts, which also makes separation and purification more expensive. So, JVO, which is PR’s partner, seems to have developed a technology that prevents the concentration from ever reaching toxic levels. But this adds capital cost and process complexity that ethanol doesn’t need. Which is where we also address the matter of cost. Now bolting on isobutinol capabilities to an existing ethanol plant may cost only 20 to 30% of that plant. But a new ethanol plant costs several hundred crores. A 20 to 30% retrofit across India surplus distilleries is not a trivial investment. Especially when the economics of isobbutinol production at Indian sugar mill conditions have not been demonstrated at commercial scale. Additionally, you need significantly more glucose to produce one liter of isobutinol compared to ethanol. And that also means you need a lot more maize and other food grains which contain glucose to make a given amount of isobutinol. And we make most of our ethanol through food grains rather than sugar cane. So, in our primer, we covered how the ethanol industrial policy is draining our food grains, even making us import dependent on maze, a crop we’ve always been self-sufficient in. In fact, the economic survey 202526 itself flagged a tension between self-sufficiency in energy and that in food. Isobbutinol could worsen this tension further. Now, isobbutinol can also be made through chemical synthesis rather than biological fermentation. But the former would be an expensive process for India. At least with fermentation, existing ethanol plants can be modified. But chemical synthesis will require building new capacities from scratch. The distance between a validated demo plant and a nationwide blending mandate backed by commercial scale production is still significant. And we haven’t even delved into the changes that automakers would need to make to their engines for isobutinol, eventually creating a similar version of the chicken and egg problem that plagued ethanol in the first place. So India’s bofuel program stands at an inflection point. The energy security logic has become more urgent than ever and sugar-based alcohols like ethanol have become part of a serious consideration that involves coal, solar, wind, and nuclear. But ethanol is hardly a foolproof solution. It delivers less energy per liter than petrol, imposes a mileage penalty that consumers notice, and takes away resources from other parts of agriculture. At the same time, EVs are catching up. Niti Aayog’s own modeling shows that faster electric two-wheeler adoption materially lowers ethanol demand just as our industrial policy tries to match it with supply. We also have an industrial policy for EV adoption, but India’s fiscal resources are finite. So the more it invests in a distillery and flex fuel ecosystem, the harder it becomes to pivot if electrification overtakes the ethanol thesis. Industrial lockin is a real risk with India’s strategy and the next few years will determine which path India has committed to. For all the sources mentioned in this video, don’t forget to check out our newsletter. The link is in the description. Coming to the second story, for 25 years, India has had a rule on the books. Households must keep their wet waste separate from their dry waste. For 25 years, almost nobody has bothered. Our kitchen scraps, vegetable peels, and leftover food go into the same bags as plastic and paper. They’re loaded on the same truck and dumped onto the same growing mountain at the edge of town. On the 1st of April this year, the government decided to try again harder. And this time around, the new solid waste management rules 2026 require four separate streams. Wet, dry, sanitary, and special care items like batteries or old medicine. They make bulk generators of waste like apartment complexes or commercial setups legally responsible for processing their own wet waste and they back the whole thing with penalties with a digital system that tracks garbage from your bin to its final destination. Now there are many reasons this might not work out but a Delhi based think tank the Council on Energy Environment and Water or CEW has put a number on what happens if we do get this right. The wet half of India’s urban garbage it argues could become a $50 billion industry generate 26 lakh jobs and flip our waste from one of our fastest growing sources of emissions into something that’s net negative in just two decades. Those are the table stakes we’re playing for. But reading their report also tells you why that bet is so hard to win. So roughly half of everything Indian cities throw away is organic. Kitchen waste, market waste, garden trimmings. Technically this is called the organic fraction of municipal solid waste. But you can just think of it as stuff that rots. By 2047, CEW thinks India cities will be generating around 28 million tons of it every year. That discarded rotting material is the single most important thing in the entire waste system because it’s a contaminant. Mix it in with dry waste and it soaks into paper, rusts metal, and coats plastic in slime. And this pushes recyclable material beyond the pale of recovery. On the other hand, if you separate this wet waste out cleanly, the rest of your garbage suddenly becomes worth recovering. Fixing wet waste, in other words, doesn’t just fix half the problem. It unlocks everything else. But how do we fix it? There are two serious options we have. One, we can compost it, which means let it break down in the open air with oxygen into a soil like manure. Or you can run it through biomemethanation. Seal it in a tank without oxygen and let bacteria turn it into bio gas. This as we wrote earlier creates fuel that can run everything from CG buses to PNG kitchens. Composting gives you fertilizer and biomethanation gives you fertilizer and fuel. So right now the split is wildly lopsided. Composting handles about 96% of India’s treated wet waste. Biomethanation just 4%. CEW’s report is essentially an argument about how fast that ratio could shift towards biomethanation and what we gain and lose depending on this. So there are essentially three futures ahead of us. We could stick to business as usual. We keep muddling along, get nowhere and the sector stays a net emitter. If we aspire for more though, we could move to an ambitious but balanced path where we collect everything, treat almost all of it, and split it evenly between composting and bio gas. And if we really get our stuff together, there’s a flatout green path. We treat all our wet waste and tilt the mix hard toward biomethanation. Let’s say 2/3 gas, 1/3 compost. The greener you go, the deeper the emission cuts are and the bigger the market becomes. from a $10 billion business at the bottom to over $60 billion at the top. Take those numbers as ballpark figures and not forecasts. But that said, a bigger market does not always translate into more jobs. If we stick to how we do things, our waste industry will employ 2.1 million people. A balanced path could lift that to 2.6 million. But the greenest, most ambitious path, the one that creates the biggest market and brings the deepest emission cuts, only creates 1.9 million jobs. So that means the most aggressive green scenario produces fewer jobs than doing nothing at all. This is the central tension of the whole transition, and it comes from a simple difference between the two technologies. Composting is labor intensive. It keeps people employed across thousands of small and midsized sites. Biomemethanation on the other hand is capital intensive. It needs sealed industrial plants with pumps, digesttors, and gas cleaning units all run by a small crew of technicians. It creates more value and it’s also environmentally better because biogas can displace fossil fuel and chemical fertilizers more powerfully than compost alone. But every step in that direction replaces a crowd of lowskilled compost workers for a handful of trained plant operators. So India faces a genuine choice. Do we want to give people employment in bulk or do we choose a path that cuts the most carbon? You can’t have both. And this is ultimately a political choice, not a technical one. But there’s an even more basic problem. That $50 billion market will only exist if there are buyers and there is a distortion that can keep them away. The two things this industry produces, manure and biogas, both must compete against products the government deliberately keeps cheap. So the manure that comes out of a composting plant, all the wet slurry left over from a bio gas digesttor is principally a direct substitute for chemical fertilizer and it can also rebuild the organic carbon that decades of ura have stripped out of India’s soil. But it comes at a price. Meanwhile, in 2025, the government spent over rupees 1.7 lakh cr subsidizing chemical fertilizer. A bag of ura is so cheap and so familiar that asking a farmer to buy heavy, bulky, organic manure instead is like asking them to set their wallet on fire. After all, city compost has existed for decades, but most of it sits unsold. So this problem is why the government now pays rups 1,500 ton in market development assistance to help organic manure sold out of registered plants close the gap. Only the subsidy on chemical fertilizers runs into tens of thousands of rupees a ton. In giving a smaller subsidy for a bulkier substitute, we might give it a gentle nudge, but we’re unlikely to genuinely shift a farmer’s choice. And then there’s the question of trust. As long as we struggle to cleanly segregate our waste, there’s no guarantee what people get. Compost made from mixed municipal waste currently can carry heavy metals or glass shards. A farmer who gets one bad batch won’t risk their livelihood on it again. So, the report suggests testing as a possible fix. Every batch of compost could be certified at an NABL accredited lab before it’s sold. That’s the same level of national accreditation that backs medical and industrial testing. Now this is expensive and unglamorous but without a credible quality stamp organic manure is just a sack of unknown sludge and no subsidy can fix that. Fuel comes with a rhyming issue. Biogas could in theory insulate Indian households from the LPG import bill since India brings in about 2/3 of its cooking gas from abroad leaving our poorest families exposed to global price spikes like the one currently being pushed by the hormones crisis. For the moment though, LPG cylinders are themselves subsidized and the gas grid hasn’t reached most homes. That’s a hostile environment for biogas for cooking to reach the scale we need. So, the entire market of its $50 billion rests on the bet that India would reform its fertilizer and fuel subsidies so that alternatives have room to look more attractive. Now, notice that none of the hard parts here are technological. We know how to compost and we know how to build a bio gas digesttor. Indo runs India’s largest plant of its kind. The technology has been proven to work. Now what doesn’t work reliably is everything around it. We struggle to arrange for clean feed stock, sign workable contracts, or incentivize buyers to embrace their output. In other words, the barriers to this $50 billion market opportunity aren’t technological but human. This is why the new rules matter so much. It’s also why they may not be enough. The biggest bottleneck here is feed stock quality. A biomethanation plant fed mixed contaminated waste can crash completely. These plants are biological. They rely on having the healthy bacteria of the right types. Upset or stress them and the plants collapse. Composting is more forgiving meanwhile, but contaminated compost is unsellable. So there’s only one answer. Get clean segregated waste in. If we fail that step, everything else fails. The S SWM rules 2026 are fundamentally the government’s attempt to legislate away the input problem, getting clean waste separated at the source. Clean feed stock, though, is only half the issue. The other half is how cities hire the people who run these plants. Most municipal tenders are still awarded on what’s called L1, where the lowest bid wins. On paper, this looks prudent, but in practice, it’s a race to the bottom. operators quote prices too thin to actually run a plant well, cash in on whatever subsidy comes with building it, and then let the facility limp or die. Worse, many contracts still pay operators by the ton of waste they haul, not the quality of what comes out. So, they’re incentivized to mix in heavy rubble to bump up the weight of their intake, ruining the very feed stock the plant needs. So CEW thinks L1 procurement should be replaced by QCBS quality and costbased selection where a bidder’s track record and plant performance count for most of the score with price only accounting for the rest. It also suggests tying payments to output which is clean compost and delivered gas and not tons. Sadly, experience teaches one not to be too hopeful. Rules requiring segregation have existed in one form or another since 2000. The reason Indor became a standout national success isn’t that it had better technology than anyone else. In the words of one expert CEW interviewed, “Success stories like Indoor tend to come down to strong administrative leadership rather than widespread compliance.” A determined municipal commissioner actually went doortodoor until the city started segregating its waste. But you can’t base an industry on the promise of determined civil servants. Nothing about India’s wet waste problem is unsolvable. The only thing keeping us from a $50 billion industry is the least glamorous capability there is of pushing people to get the basics right. That’s often the hardest thing to solve. Now coming to the tidbits, ARI has rolled back a requirement that forced automakers to obtain separate domestic value addition or DVA certificates for export models under the auto PLI scheme. If an export variance bill of materials is identical to the domestic version, the existing DVA certificate will now suffice. a relief for manufacturers who argued the extra paperwork added months of compliance burden. Coming to the next tidbit, India has added silver grains, powder and other 99.9% purity forms to the restricted imports list requiring prior authorization from the DGFT. The move comes after silver imports hit a record 12 billion in FY26, up from $4.8 billion the year before. Coming to the final tidbit. President Trump signed an executive order creating a voluntary framework for the US government to review national security risks of advanced AI systems for up to 30 days before public release. Trump had delayed signing a similar order in May over concerns it would hamper America’s AI lead. The final version keeps participation operational and limits the review window with the NSA director deciding which models qualify for scrutiny. That’s all the news I have for you.
