From residueto refinery spec.

Our thermochemical process is developed and owned entirely by our team — no licensed IP, no royalty dependency. Five steps take agricultural residue to a certified fuel that a diesel engine cannot tell apart from fossil.

01 — How it works

The science behind the transformation

A precise thermochemical and catalytic pathway, developed entirely in India, from farm residue to market-ready fuel.

Five steps. Each one has a specification the batch must meet before it moves on.

01
Feedstock collection and verification
Agri-waste and agro-industrial by-products are sourced from regional farms and food processing units. Every batch is characterised and verified against our feedstock specifications — moisture content, organic composition, energy potential — before acceptance.
Out — verified residue
02
Pre-treatment and preparation
Incoming feedstock undergoes proprietary pre-processing — drying, sizing and conditioning — to reach the precise physical and chemical state required for optimal conversion efficiency in the downstream reactor.
Out — reactor-ready feed
03
Thermochemical conversion
The core of the Greenjoules process. Prepared feedstock enters the proprietary thermochemical reactors at our plants, where controlled temperature, pressure and residence time convert organic material into bio-crude — a raw intermediate with high energy density.
Out — bio-crude
04
Catalytic upgrading and refining
Bio-crude undergoes catalytic hydrotreatment and distillation, upgrading its molecular structure to match fossil fuel specifications precisely. This is the step where waste becomes a product indistinguishable from what leaves a petroleum refinery.
Out — finished fuel fractions
05
Testing, certification and dispatch
Final product is tested against BIS:1460 and international standards, certified, and dispatched to customers through existing fuel logistics infrastructure. No special handling. No dedicated supply chain. It simply replaces fossil diesel — at scale.
Out — certified, dispatched

Fuels that are better in every way that matters

Each Greenjoules product is a drop-in replacement for its fossil counterpart — identical performance, same supply chain, a fraction of the carbon footprint.

03 — Circular economy

Nothing leaves as waste

Our biorefinery model ensures every input generates value. By-products are upcycled into high-value applications rather than disposed of.

Zero hazardous waste is generated in our process.

Biochar

Soil amendment and long-duration carbon sequestration.

Refined silica

Extracted from the biochar stream for industrial use.

Activated carbon

Filtration and industrial process applications.

LPG-equivalent fraction

A renewable gas fraction recovered during refining.

04 — Next in change

The same platform, the harder problems

The feedstock is agri-waste. The platform is proven. The next fuels are a matter of engineering and time.

Coming soon

Sustainable Aviation Fuel

The same agri-waste feedstock, refined to ASTM D7566-compliant jet fuel with up to 80% lower lifecycle CO₂. No new engines, no new infrastructure.
