altM, a deep-tech materials company focused on sustainable alternatives to fossil-derived chemicals, has announced the launch of its fully integrated biorefinery pilot plant in Bengaluru.

This marks a key milestone in the company’s transition from laboratory R&D to pilot-scale manufacturing. The facility will produce industrial-grade, bio-derived materials that are compatible with existing manufacturing systems. altM’s pilot plant operates at a capacity of 15–50 tonne per annum, allowing the company to scale production and test various performance metrics such as throughput, yield, quality, and unit economics. Initial materials produced are being evaluated for use in cosmetics, wood adhesives, and construction inputs, sectors that traditionally rely heavily on petrochemical-derived components.

Apoorv Garg, CEO & Co-Founder of altM, stated, “This pilot is about proving that bio-based materials can meet industrial performance expectations and commercial requirements at scale.” The plant produces multiple functional materials, including cellulose-based rheology modifiers, formaldehyde-free lignin wood adhesives, and UV blockers, while improving scalability and cost-efficiency. The pilot plant is expected to generate commercial revenue starting in Q1/2026.
