What We Do

We make fuel from waste.
Not as a compromise — as an upgrade.

Greenjoules is a deep-tech biorefinery operating from Chakan, Pune. We take agri-waste and agro-industrial residues — materials that would otherwise be burned in open fields — and convert them through a proprietary thermochemical process into second-generation biofuels that are chemically indistinguishable from their fossil counterparts.

The critical difference: our fuels carry among the lowest lifecycle carbon footprints of any fuel available anywhere in the world today. And unlike first-generation biofuels, not a single food crop is diverted.

🌾

Zero food vs. fuel conflict

Agricultural residues only — rice husk, sugarcane press mud, paddy straw. No cropland diverted. No food chain disrupted.

🔬

Proprietary process technology

Our thermochemical conversion process is developed and owned entirely by our team. No licensed IP, no royalty dependency — full technical control at every step.

⛽

True drop-in replacement

Meets BIS:1460 (Indian diesel standard). Surpasses Euro VI. No engine or infrastructure modification required — it simply replaces fossil diesel, litre for litre.

How It Works

The Science Behind
the Transformation

Our proprietary process — developed entirely in India — takes agricultural residues through a precise thermochemical and catalytic pathway to produce certified, market-ready clean fuel.

Feedstock Collection & 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.

🌾

Pre-Treatment & Preparation

Incoming feedstock undergoes proprietary pre-processing — drying, sizing, and conditioning — to achieve the precise physical and chemical state required for optimal conversion efficiency in the downstream thermochemical reactor.

🔧

Thermochemical Conversion

The core of the Greenjoules process. Prepared feedstock enters our proprietary thermochemical reactor, where controlled temperature, pressure, and residence time convert organic material into bio-crude — a raw intermediate with high energy density.

🔥

Catalytic Upgrading & Refining

Bio-crude undergoes catalytic hydrotreatment and distillation — upgrading its molecular structure to precisely match fossil fuel specifications. This is where the magic happens: waste becomes a product indistinguishable from what comes out of a petroleum refinery.

⚗️

Testing, Certification & Dispatch

Final product is tested against BIS:1460 and international standards, certified, and dispatched to customers via existing fuel logistics infrastructure. No special handling. No dedicated supply chain. It simply replaces fossil diesel — at scale.

ISCC Biocircular Certified

Third consecutive year · Independent annual audit

Credibility & Certification

We Don't Just Claim Sustainability. We Prove It — Every Year.

In a sector where greenwashing is rampant, Greenjoules subjects its entire production chain to the most rigorous third-party verification available. The ISCC Biocircular certification is not a marketing award — it is an independent annual audit of every input, transformation, and output in our process.

ISCC Biocircular Certified — 3rd consecutive year. Each certification requires a fresh, independent audit. Three years running means sustained integrity, not a one-time achievement.

Commercial operations at Chakan, Pune. Not a pilot or a prototype. A running commercial biorefinery with real customers, real offtake agreements, and real revenues.

Series B — institutional-grade investors. Our fundraise has attracted some of the most credible names in India's energy investment world, providing independent validation of our technology and trajectory.

Fully owned process technology. No licensed foreign IP, no royalty dependency, no technology risk from external partners — complete technical sovereignty.
