India Burns 60% of Its Sugarcane Trash: A ₹-Billion Bioeconomy Opportunity Going Up in Smoke

While national debate on crop residue burning largely centres on paddy stubble in Punjab and Haryana, sugarcane trash has quietly become one of India's most neglected biomass challenges. A recent assessment by Chesta Bio Energy places the annual generation of sugarcane trash at nearly 17.9 million tonnes — a figure that dwarfs many other agricultural residue streams.

More than 60% of this volume is openly burned in fields after harvest. Each tonne consigned to the flame releases carbon dioxide and other greenhouse gases into the atmosphere while simultaneously destroying the nitrogen, phosphorus, and potassium that the soil needs for the next crop cycle. The twin losses — environmental and agronomic — make field burning of cane trash a costly habit that farmers, sugar mills, and the broader agri-sector can ill afford to continue.

The core argument from Chesta Bio Energy's assessment is that sugarcane trash is not a disposal problem — it is a misclassified asset. The residue that farmers currently burn could, with the right infrastructure, be converted into:

• Biochar — a soil amendment that improves fertility and permanently sequesters carbon in the ground
• Renewable energy — displacing fossil fuels in industrial and rural applications
• Carbon credits — generating additional income streams for farmers and biomass aggregators
• Circular bioeconomy products — creating rural employment while cutting emissions

The assessment notes that the technology required for these conversions already exists, and the raw material is in abundant supply. What is currently absent is a structured ecosystem that connects all the relevant actors — farmers, sugar mills, entrepreneurs, researchers, policymakers, and industry — into functional biomass value chains.

The diagnosis from Chesta Bio Energy is pointed: India's biomass challenge is not a shortage of resources, but a shortage of value creation. The country has the feedstock and the technical know-how; what is missing is coordination.

Building a viable sugarcane trash value chain would require sugar mills — which sit at the natural aggregation point for cane residue — to act as anchors, working alongside rural entrepreneurs, women-led clean-energy enterprises, and policymakers who can provide enabling regulation. The assessment positions regenerative agriculture as both the end-goal and the selling point: biochar returned to cane fields can rebuild the very soil nutrients that burning destroys, creating a closed loop where residue management becomes soil investment.

For commodity traders and agri-businesses, the carbon credit dimension adds a financial layer beyond farm-gate savings — one that could make biomass aggregation commercially attractive even before accounting for energy or product revenue.

India's residue management policy has largely focused on paddy-growing states, with schemes incentivising happy-seeder technology and ex-situ biomass use in power plants. Sugarcane trash has received comparatively little structured attention, even though it represents a significant and annually recurring biomass surplus concentrated around sugar mill catchment areas — making it logistically easier to aggregate than paddy straw.

For policymakers, the Chesta Bio Energy assessment implicitly points to several levers: biomass procurement obligations for sugar mills, carbon credit facilitation for smallholder cane farmers, and rural enterprise support for biochar producers. Without policy scaffolding, the economics of sugarcane trash valorisation remain challenging for individual farmers to act on alone. The climate imperative — reducing agricultural greenhouse gas emissions ahead of India's NDC commitments — adds urgency to getting this framework right.
