Bengaluru biomaterials startup raises $10.3M to turn crop residue into cosmetic ingredients
AltM, a Bengaluru biomaterials startup founded by two former Tesla manufacturing executives, has closed a $10.3M Series A. Rainmatter by Zerodha and Mela Ventures are new investors. Omnivore, Theia Ventures, Aureolis Ventures, Spectrum Impact and strategic angels, all existing backers, also took part. The money is meant to move AltM from pilot to commercial-scale manufacturing, expand R&D and customer qualification programmes, and grow its engineering and commercial teams.
The core is AltMorph, a thermochemical biorefinery that takes residues such as sugarcane bagasse and rice straw and separates the biomass into cellulose, hemicellulose and lignin. Each fraction becomes a different ingredient, so one feedstock yields several products. Since a $3.5M seed round three years ago, AltM has built an integrated R&D and pilot facility, expanded its lab footprint nearly fivefold, commissioned a demonstration facility, and taken six molecules to demo scale. Three of those were selected for pilot manufacturing. The first products heading toward commercialisation are a lignin-derived SPF booster for sunscreen, a cellulose-based rheology modifier, and bio-based ferulic acid for cosmetics. Target industries also include textiles, industrial chemicals, construction and packaging.
This matters for goods because it points to a route to materials that do not depend on fossil inputs, and it gives farm residue a use as a feedstock. If it scales, ingredients get a domestic, renewable source. That would also tie farm income to a waste stream.
The caveats are large. Production is still at pilot and demo scale, and the products have yet to reach commercialisation. No cost-parity data against fossil-based materials was given. The claim that AltEnol, its bioethanol technology, cuts enzyme dependence by up to 70% is the company's own. Biorefineries in general struggle with costs that can exceed regulated product prices. Watch for commercial-scale output and prices.
