AltM raises $10.3M to scale bio-based materials from farm waste
Indian biomaterials startup AltM has secured $10.3 million in Series A funding to commercialize its technology for converting agricultural waste into sustainable industrial inputs for cosmetics, textiles, and packaging.
AltM, a biomaterials startup founded by Tesla alumni, has raised $10.3 million in a Series A funding round. The investment, led by new backers Rainmatter by Zerodha and Mela Ventures, comes just over three years after the company's $3.5 million seed round, bringing its total funding to approximately $13.8 million.
Since that seed investment, AltM has significantly expanded its operational footprint. It has built an integrated research, development, and pilot manufacturing facility in Bengaluru. The company's laboratory space has grown nearly fivefold in less than two years, and it has commissioned a demonstration manufacturing unit.
Technology and product commercialization
AltM's core technology is its AltMorph thermochemical biorefinery. This process converts agricultural byproducts like sugarcane bagasse and rice straw into high-value, bio-based materials. The system separates the biomass into its core components: cellulose, hemicellulose, and lignin. These are then refined for use across multiple industries.
The company's first products are advancing toward commercial sale. They include a lignin-derived SPF booster for sunscreen, a cellulose-based rheology modifier for cosmetics, and bio-derived ferulic acid for personal care formulations. The technology is noted for delivering high-purity inputs with low ash content, which enhances fiber performance in textiles.
Scaling from lab to market
Moving from laboratory discovery to commercial production presents a major hurdle. AltM has progressed six molecules to demonstration scale. From these, three have been selected for pilot plant production. Yugal Raj Jain, AltM's co-founder and COO, explained the challenge. He stated that moving a material from the lab requires processes that can consistently produce the same material at increasing scale.
This funding is aimed squarely at overcoming that scaling challenge. The capital will enable the company to refine these consistent manufacturing processes for its selected pilot molecules.
Strategic supply chain and environmental impact
AltM's model leverages a vast and problematic resource: India's agricultural residue surplus. A study for India's National Biomass Atlas estimated this surplus at about 230 million tonnes annually. Much of this crop waste is traditionally burned in fields, contributing to air pollution.
The startup aims to rewire foundational industrial supply chains. Co-founder Apoorv Garg framed the mission. "Industrial manufacturing has relied on fossil carbon for more than a century," he said. "We are building a new source of industrial carbon from agricultural residue."
By converting this zero-waste biomass, the technology addresses two critical issues. It tackles the greenhouse gas emissions linked to petroleum-derived materials. It also maximizes resource utilization from the agricultural sector. Abhinav Negi highlighted the broader significance, noting that rewiring supply chains away from fossil inputs is one of the most critical challenges facing modern manufacturing.
The company's progress is now measured in tangible manufacturing milestones. With six molecules at demonstration scale and three advancing to pilot production, AltM is building the foundation for scalable, fossil-free industrial materials.
