How it works

From waste stream to certified fuel.

No burning, no waste. Our patented pyrolysis process breaks down hydrocarbons others throw away and rebuilds them into premium, spec-grade fuel and feedstock.

Plain English

What is pyrolysis?

Pyrolysis heats organic material — like waste oil and hydrocarbons — to high temperatures inside an oxygen-free chamber. With no oxygen it can't burn, so instead the heavy, tangled molecules break apart into lighter, valuable ones: diesel, gasoline, LPG, and refined feedstock. It turns something that was headed for disposal into a resource — the circular economy, working.

Plain English

What is ASTM 2.5 feedstock?

ASTM International sets the standardized specifications the fuel industry tests against. An ASTM-certified feedstock meets a defined, measurable quality spec — so a refiner knows exactly what they're buying, with no guesswork. SDG's patented process consistently delivers feedstock to the ASTM 2.5 grade for some of the largest oil & gas companies in the world.
