Context
TAMS Tribal Green Fuels Private Limited was incorporated in April 2023 in the buffer villages of Sathyamangalam Tiger Reserve, Tamil Nadu, and received a Rs 25 lakh grant in May 2023 under the Tamil Nadu government's SC/ST Startup Fund to manufacture biomass briquettes from Lantana camara, an invasive shrub that suppresses native forage species.
Activities
Owned by 30 tribal shareholders, the company clears Lantana and processes it into fuel briquettes with a calorific value above 4,800 kcal/kg, sold to industrial buyers as a wood-fuel substitute.
Results
Since beginning operations in May 2024, the company has sold 808 tonnes of briquettes, cleared nearly 150 acres within the reserve's core area, and supported around 350 tribal members with regular livelihood income across 47 villages, on top of Rs 1.5 crore in separate equity funding raised through Startup Tamil Nadu.
Conclusions
Unlike a comparable Lantana-removal programme at Kanha Tiger Reserve which has an independent multi-year outcome study, no independent ecological monitoring of native vegetation or wildlife recovery from TAMS's clearance has been published, and the 150-acre cleared area is a small fraction of the reserve's total infestation after about one year of commercial operation.
Implementation
Indicative cost
Low (< €50k) — Rs 25 lakh (~US$30k) state grant plus Rs 1.5 crore (~US$180k) equity funding.
Time to results
Medium (1–3 years) — Incorporated April 2023; briquette operations since May 2024.
Staffing & skills
30 tribal shareholders of TAMS Tribal Green Fuels, Tamil Nadu Forest Department
Conditions for success
dedicated state SC/ST Startup Fund seed grant
tribal ownership structure aligning income with reserve-compatible livelihoods
industrial offtake market for briquettes as a wood-fuel substitute
Common failure modes
no independent ecological monitoring to confirm native-vegetation or wildlife recovery from clearance
cleared area still a small fraction of total infestation after about a year
