What happens to a crop after the harvest is over? Beyond the produce that reaches markets and kitchens, farming leaves behind stalks, leaves, fruit peels and other organic residues. Often treated as waste, these materials can become a valuable resource when handled differently. Biochar provides a way to turn agricultural by-products into a carbon-rich material that may offer benefits for soil management and the environment.
Jain Irrigation Systems Limited is exploring this approach through its biochar facility in Jalgaon, Maharashtra, connecting agricultural residue management with the potential for long-term carbon storage.
A vision that grew from the soil
The story of Jain Irrigation is closely associated with its founder, Dr Bhavarlal Hiralal Jain, affectionately known as Bhau. Born in Wakod, Jalgaon district, in 1937, he began his entrepreneurial journey in 1963 with a small kerosene sub-dealership.
His interests gradually turned towards agriculture and the challenges faced by farmers. Over the decades, Jain Irrigation expanded into micro-irrigation, agricultural technology, tissue culture, food processing and renewable energy.
At the heart of this journey was a simple philosophy: “Leave this world better than you found it.” Bhau received the Padma Shri in 2008 in recognition of his contribution. His vision continues to offer a way of looking at agriculture as a connected system in which water, soil, energy and natural resources all matter.
Biochar reflects this broader perspective by asking a different question of agricultural waste: could what remains after production become the starting point for something useful?
How agricultural waste becomes biochar
Biochar is produced through pyrolysis, a process in which biomass is heated in an environment with limited oxygen. Rather than burning completely, the organic material is transformed into a carbon-rich solid.
Suitable agricultural residues and fruit-processing by-products can provide feedstock for this process. Converting them into biochar offers an alternative use for materials that might otherwise be discarded or burned.
The resulting material can have applications in agriculture. Depending on its characteristics and the soil in which it is used, biochar may help improve water retention, influence nutrient availability and contribute to soil management. Its performance varies, however, so these benefits cannot be assumed for every farm.
Biochar also offers a potential pathway for carbon removal. As plants grow, they absorb carbon dioxide from the atmosphere. Converting some of this biomass into stable biochar can help keep a portion of that carbon stored for a prolonged period. The overall climate benefit depends on production emissions, feedstock sourcing, carbon stability and how the material is used.
Jain Irrigation’s biochar plant in Jalgaon, Maharashtra, is designed to handle around 20,000 tonnes of agricultural and fruit-processing waste each year, with a stated capacity to process more than 50 tonnes of feedstock daily.
The initiative reflects an effort to give agricultural by-products a productive role beyond their original purpose. Rather than treating agricultural residues simply as waste, this approach explores how suitable materials can be repurposed for potential use in agriculture and environmental management.
Operating at this scale requires reliable feedstock supplies, careful process management and responsible handling of emissions and by-products. The benefits of biochar also depend on its quality and how well its properties match the needs of the soil in which it is applied.
Carbon storage and the importance of verification
Biochar’s potential to retain carbon has made it relevant to climate action. Jain Irrigation’s project has been associated with the carbon removal certification process through Puro.earth. The project’s preliminary assessment and progress towards full certification should not be confused with completed certification or the confirmed issuance of carbon removal credits.
Credible carbon removal claims require appropriate measurement, reporting and verification. Assessing the climate benefit also involves considering the biomass source, processing emissions and the durability of the carbon stored.
The agricultural connection is equally significant. With its established activities in irrigation, agricultural technology and food processing, Jain Irrigation operates across several stages of the agricultural value chain. Biochar offers a possible link between these activities, allowing suitable by-products to be considered as resources rather than simply waste.
The journey from agricultural residue to biochar illustrates how a change in perspective can open new possibilities. Material once regarded as unwanted can become a resource for soil management and carbon storage when processed and used responsibly.
For Jain Irrigation, this approach reflects the spirit of Bhau’s founding philosophy. Improving agriculture does not always mean introducing something entirely new; sometimes, it means discovering a better use for what is already available.
Biochar is not a universal solution to soil degradation or climate change. Yet it presents an opportunity to connect agricultural waste management with resource efficiency and environmental responsibility, bringing the idea of leaving the world better than we found it into the everyday realities of farming.
