I would convert crop residues such as rice husk, cotton stalks, coconut shells and prunings into biochar using simple kilns, then charge it with compost or cow urine and sell it as a soil conditioner to farmers, nurseries, kitchen gardeners and landscapers.
I would also offer residue collection from farmers who would otherwise burn it.

Every season, farmers burn crop residue because they have no other quick way to clear fields, and the smoke harms everyone. At the same time, many soils are tired and low in organic matter. Biochar turns that residue into a stable, porous material that can help soils hold water and nutrients. I would make it locally and sell it to people who care about their soil.

Crop residue burning is a major environmental issue in several states, and there is pressure to find alternative uses. Interest in soil health, organic farming and natural farming has grown, and biochar has drawn attention from researchers and farmers as a soil amendment. Urban gardeners and nurseries also look for quality soil conditioners. Small producers using clean kilns can supply local markets at a reasonable cost.
Buyers are organic and natural farmers, nurseries, landscapers, kitchen gardeners and potting mix makers. Suppliers are farmers with crop residue. Their trigger is soil improvement, water retention in sandy soils, or a wish to avoid burning residue. I would reach buyers through nurseries, gardening groups, FPOs and demonstration plots.
I sell biochar by the bag or by the tonne, with higher prices for charged or blended biochar suitable for direct use in pots and beds. Bulk sales go to nurseries and mix makers. Residue collection may be free or paid depending on the area. Costs are kiln construction, labour, transport, charging materials and packaging.
The edge is local production from local residue with a clear story about reducing burning and improving soil. Properly charged biochar ready for use is more valuable than raw charcoal.
I would recommend this to someone in a crop growing area interested in soil and environment. I would avoid it without a clean kiln method. Make a few batches and run demonstration plots.

Simple kilns can be built at low cost from metal drums or brick, while improved retorts cost more but reduce smoke. Other costs are tools, a crushing setup, storage, bags and transport. A small unit usually costs in the tens of thousands.
Income depends on output, which depends on residue supply and kiln capacity, and on how much is sold as higher value blended product. Retail bags for gardeners earn more per kilogram than bulk sales. Demonstration plots that show results help raise demand over seasons.
No sourced cost or earnings figures exist for this idea yet, so none are shown. Nothing here is an estimate.

Build a small kiln and test with available residues.
Charge biochar with compost and test it on a few plots and pots.
Share results with nurseries and gardeners.
Bag retail packs and supply bulk to nurseries.
Arrange residue supply from nearby farmers.
First sales can come after a few batches and some demonstration results.
A charcoal like material made by heating organic matter with limited oxygen, used as a soil amendment.
Raw biochar can absorb nutrients from soil at first. Charging with compost or nutrients makes it ready to use.
Rice husk, stalks, shells and prunings are commonly used.
Results depend on soil, crop and use. Demonstrations help show what works locally.
Poor methods create smoke. Improved kilns reduce it significantly.
