About Devi
An integrated platform for clean industrial growth
We operate where energy ownership, infrastructure and material innovation meet — bringing a rare, end-to-end perspective to industrial sustainability.
Who we are
More than a manufacturer — a platform company
Devi is not a standalone materials producer. We control the critical inputs — clean energy, infrastructure and process design — that let us deliver consistent, future-ready industrial solutions.
By combining renewable power generation and transmission with advanced-material manufacturing, we create solutions that are efficient and reliable, and environmentally responsible at their core. Our model is built to help industries reduce risk, lower emissions and build long-term operational resilience.
- Own and operate renewable energy assets
- Develop transmission and evacuation infrastructure
- Apply that expertise to advanced-materials manufacturing
The integration model
Energy-led manufacturing
Traditional manufacturing depends on external energy, exposed to price volatility and carbon risk. Devi takes a different path: our advanced-materials roadmap is anchored in renewable energy from the source.
- Energy security and cost stability
- Lower carbon footprint across production
- Improved ESG performance
- Long-term supply reliability
Our vision
To build a globally trusted industrial platform where renewable energy and advanced materials work together to enable cleaner, more efficient and more resilient industries — where growth is powered by sustainable energy, responsible resource use and innovation-driven materials.
Our mission
To develop and operate an integrated ecosystem — renewable energy assets, infrastructure expertise and advanced-materials manufacturing — that delivers reliable, high-performance and sustainable industrial solutions through disciplined execution and long-term thinking.
Our approach
Energy-led, engineering-driven and sustainability-first. By integrating clean power at the source, focusing on application-specific innovation and partnering closely with customers, we ensure consistent quality, long-term reliability and measurable impact.
Products · Activated carbon
High-performance adsorption, powered by clean energy
Activated carbon is critical wherever purity, safety and performance matter. Our platform delivers high-efficiency adsorption media, produced from renewable bamboo and backed by responsible manufacturing.
Our platform
Engineered for performance-critical applications
Devi's activated carbon is designed to solve complex purification, separation and treatment challenges. Every product is engineered to deliver predictable results under demanding operating conditions.

Fine particulate with a high surface-to-volume ratio and short diffusion distance, milled and sieved to a controlled powder.
Granular (GAC)
Durable granules from high-carbon bamboo, steam- and chemical-activated at 600–1200 °C to build a highly permeable, wide-pore structure.
Pelletised
High-strength cylindrical pellets (0.8–5 mm) for low-pressure-drop, gas-phase duty. Thermally reactivatable and reusable.

Renewable ecosystem
Renewable energy at the core of everything we make
From agro-forestry and captive bamboo to hydropower, transmission and renewable gas, our ecosystem secures clean inputs across the industrial value chain.
Agro-forestry & captive bamboo
A renewable-resource-led manufacturing model
Devi's carbon production is supported by agro-forestry and captive cultivation of bamboo — a fast-growing, renewable biomass that removes dependency on forest wood and involves no felling of trees.
Bamboo matures in 3–5 years and regenerates naturally after harvesting. Our plantations are established on non-forest and degraded lands, ensuring full compliance with environmental and forest-conservation norms.
Sustainability & compliance
Why our feedstock is a strategic advantage
Renewable feedstock
A rapidly renewable resource with predictable supply cycles and long-term raw-material security.
No deforestation
Sourcing is independent of natural forests and requires no tree cutting or forest clearances.
Carbon & climate benefit
Bamboo plantations act as strong carbon sinks, reducing net footprint across the value chain.
Captive & traceable supply
Controlled cultivation ensures traceability, quality consistency and stable production for buyers.
ESG & regulatory alignment
Supports environmental compliance, sustainability reporting and renewable-resource classification.
Rural integration
Farmer participation and agro-forestry development contribute to inclusive rural growth.
Responsible silica manufacturing
High-purity silica, produced responsibly
Silica is inert, non-toxic and chemically stable — an essential input for rubber and tyres, electronics, pharmaceuticals, agriculture, coatings, cosmetics, batteries, water treatment and industrial gases. Our processes are optimised to minimise waste, reduce emissions and use resources efficiently.
- High purity & consistency across batches
- Environmentally responsible processing with dust control and waste minimisation
- Regulatory & industry compliance for domestic and export markets
- Application-specific variants for each industry
- Stable, scalable supply for long-term assurance
