Brisil

Brisil, legally Brisil Technologies Private Limited, is a Vadodara, Gujarat-based chemicals manufacturer that converts rice husk ash — the residue left after rice husk is burned as fuel in power plants — into precipitated silica and highly dispersible silica (HDS). Its stated aim is to address both the disposal problem created by large volumes of rice husk ash and industrial demand for silica, which is conventionally produced from river sand and quartz through an energy-intensive, higher-emission process.

The company's silica grades are sold as reinforcing fillers and additives into tyres, industrial rubber (natural and synthetic), footwear, paints, toothpaste, plastics and powdered food products such as salts, sugar, spices and soup powders. In tyre applications, HDS is positioned as a filler for energy-efficient "green" tyres, with the company describing reduced friction and wear and improved fuel efficiency; in footwear it cites improved durability and stiffness. Brisil states that its technology has been tested at pilot scale and commercialized, and that its HDS has been validated by third-party agencies and by customers.

Brisil operates a commercial facility with capacity of 400 tonnes per month and has said it plans to scale to 3,000–5,000 tonnes per month, against a reported monthly demand pipeline of 6,000 metric tonnes. It describes itself as an R&D-focused organisation developing additional silica grades and evaluating other chemicals extractable from biomass waste.

Founding story

The concept originated when a large rice-husk-fired power generation company asked the founding team to develop a technology to make use of the ash left over from its electricity generation. Investigating further, the team found ash disposal was a widespread problem and that the silica in the ash was valuable, particularly for the tyre and rubber industries; validation from a senior executive at a leading tyre company confirmed the commercial potential. Brisil was founded in 2016 by Tanmay Pandya, who holds a B.Tech in chemical engineering from the Indian Institute of Technology and previously co-founded and served for more than five years as director of the cleantech startup Bridgedots.

Business model

B2B industrial materials manufacturing: Brisil produces and supplies precipitated silica and highly dispersible silica grades to manufacturers in tyres, rubber, footwear, paints, toothpaste, plastics and food powders. Its inputs are secured through long-term rice husk ash supply contracts with companies that generate large ash volumes.

Sales of manufactured silica products to industrial customers (hardware/material sales), with grades tailored to specific applications.

Traction

Brisil reports commercialized products validated by third-party agencies and customers, a commercial facility running at 400 tonnes per month, a monthly demand pipeline of 6,000 metric tonnes, and a customer mix spanning domestic and international buyers including recognised footwear and tyre companies. Employee counts reported by third parties range from roughly 11–50 to 41–60.

Latest developments

In January 2026 Brisil announced a Rs 3 crore pre-seed funding round led by Momentum Capital with participation from Fondation Botnar, earmarked for expanding production capacity using its zero-waste chemical process, strengthening the team and scaling operations. Alongside this it outlined plans to raise capacity from 400 to 3,000–5,000 tonnes per month and to grow its international presence in South East Asia and Europe.
