India’s ambitious target of 5,000 compressed biogas plants by 2030 hinges not on technology or capital, but on the urgent development of a robust, farm-level biomass supply chain.
India has set itself an ambitious target: commissioning over 5,000 compressed biogas (CBG) plants by 2030. As of early 2026, 133 CBG plants are operational with a combined capacity of about 926 tonnes per day, while another 83 remain under construction. The gap between our current position and our ultimate destination is enormous, and closing it will require far more than just capital and technology.
Six years of working in this market have taught me a vital lesson: building a biofuel plant is the easiest part of the business. A facility can be designed, financed, and constructed within eighteen months. What cannot be built in eighteen months is the surrounding ecosystem-the intricate network of farmers, aggregators, transporters, and quality control processes required to keep feedstock flowing consistently across all seasons, at a price that remains viable for everyone in the supply chain.
Most struggling biofuel projects in India do not fail because of technological shortcomings; they fail because the underlying supply chain was never established. If 5,000 plants are to successfully emerge, this ecosystem must scale first-or at least scale alongside them. It cannot be treated as an afterthought.
Every winter, the nation witnesses the same recurring narrative. Fields are set ablaze post-harvest, smoke drifts across state borders, and Delhi's air quality deteriorates to unbreathable levels. The subsequent public conversation usually ends with blame, rarely addressing the fundamental economics that drive this behaviour.
Farmers burn stubble for a simple reason: it is the fastest and cheapest method to clear fields for the next sowing cycle. The window between harvesting paddy and sowing wheat is exceptionally narrow. Hiring labour or machinery to remove residue demands time and money that farmers simply do not have, whereas burning costs a single matchstick. Until removing agricultural residue becomes easier and more financially rewarding than burning it, regulations and appeals will achieve little on the ground.
Furthermore, this is no longer just Delhi's problem. Air quality is deteriorating rapidly across Indian cities in both the north and the south, as the stubble burned in one state settles in the lungs of another.
The equation only changes when a buyer appears at the farm gate. When a system effectively collects residue from the field within that narrow post-harvest window, compensates the farmer, and hauls it away seamlessly, burning ceases to make sense. We have witnessed this shift first-hand wherever collection networks reach. The farmer is not the villain in this story; he is a supplier waiting for an established supply chain.
When people discuss biofuel infrastructure, they typically envision digesters, pipelines, and dispensing stations. However, the infrastructure that actually determines whether this industry succeeds is far less photogenic: baling machines in fields, collection centres in villages, storage yards that keep biomass dry through the monsoon, trucks that arrive on schedule, and moisture meters at the weighbridge.
Biomass is inherently bulky, highly seasonal, and scattered across millions of small farms. A single CBG plant of meaningful capacity requires a steady, daily supply of feedstock, yet the paddy straw it relies upon arrives in a brief burst over a few weeks. Bridging this operational mismatch requires aggregation at a serious scale: collecting from thousands of farms, densifying the material, storing it scientifically, and managing supply releases throughout the entire year.
This is the foundational layer where we have focused our efforts, and it is where the most complex challenges reside. These include price discovery in the absence of a reference market, maintaining quality standards when every lot varies, and building trust between a farmer in one state and a plant in another. None of these hurdles can be solved by machinery alone. They are resolved by networks, and networks take years to cultivate. This is precisely why the work must begin now, well ahead of the plants.
There is a quieter benefit to this model that deserves significantly more attention. Agricultural work is highly seasonal, and the months following a harvest are traditionally lean. Biomass aggregation completely flips this calendar. Collection, baling, transport, storage, and processing all peak during the post-harvest window, generating vital employment in villages precisely when work is scarce. The residue that was once a liability becomes an additional income stream for the farmer, while the surrounding logistics create local jobs for individuals who would otherwise migrate for seasonal work.
Multiplying this impact across the catchment areas of 5,000 plants reveals a significant macroeconomic picture: a rural economy earning directly from what it once burned, while securing off-season employment within the village itself. Energy policy rarely doubles as effectively as rural employment policy, but this initiative does.
Among all biofuels, compressed biogas holds a distinct advantage: it does not need to build its own demand infrastructure from scratch, because the CNG market has already established it.
Purified biogas with a methane content typically at or above 95 per cent in practice is functionally identical to CNG. The Bureau of Indian Standards specification for CBG directly mirrors the CNG standard, and the government permitted its utilisation in motor vehicles back in 2015. Consequently, any vehicle running on CNG can be fuelled with CBG without any modifications. The pipelines, dispensing stations, and vehicles are already on the ground.
Very few renewable fuels manage to bypass the classic chicken-and-egg dilemma of demand. CBG enters a mature market directly. With the mandatory blending of CBG into CNG and PNG now underway and set to scale over the coming years, the demand side is entirely settled. Everything now depends on the supply side, which brings our focus squarely back to the farm.
The most compelling aspect of the CBG narrative is what a plant can evolve into over time.
Raw biogas contains roughly 40 per cent carbon dioxide, which is removed during the purification process. Captured and processed efficiently, that CO2 becomes a valuable, saleable product for industrial and food-grade applications, as well as a prime candidate for sequestration. Meanwhile, the digested slurry left behind serves as fermented organic manure-a secondary revenue stream that returns essential nutrients to the very fields that grew the feedstock, beautifully closing the agricultural loop.
Furthermore, verified emission reductions from these plants are increasingly monetizable as carbon credits, adding a third revenue stream. As technology continues to mature, clear pathways are emerging for deriving hydrogen directly from biogas streams.
A facility that begins its lifecycle producing a single gas product can ultimately scale into a multi-product biorefinery, delivering fuel, fertiliser, CO2, and carbon credits. Project economics that might appear modest on gas sales alone look vastly different when the entire molecule is successfully monetised. This is the industry's definitive trajectory, and facilities being engineered today must be designed with this future in mind.
India's biofuel evolution will not be decided in corporate conference rooms or on drawing boards. It will be decided in mandis, on rural farm roads, at weighbridges, and within village collection yards. The processing plants will inevitably arrive; the necessary capital and policy frameworks are already falling into place. The critical question remains whether our ground-level operations can scale fast enough to feed them.
That is the immediate task facing everyone building within this industry: making it entirely effortless for a farmer to sell what he once burned, and completely reliable for a plant to buy it. If we execute this correctly, the 5,000 projected plants will not just get built-they will run efficiently and power India's sustainable future.
