Reliable Sludge Disposal, Built for the Future.

We deliver guaranteed disposal you can count on—no risk, no surprises.

The Orbital Process, Simplified

Drying

We start with wet, dewatered sludge and remove most of the moisture in a low-temperature dryer. Drier solids = less energy later and a consistent feed to the next step.

Carbonization

In an oxygen-free PYREG reactor, we apply indirect heat. That sustained temperature and residence time thermally break down pathogens, microplastics, PFAS and other contaminants. There’s no flame and no combustion—just controlled thermal decomposition that creates two outputs: biocarbon and syngas.

Biocarbon

A durable, porous carbon that locks away CO₂ and goes to work. Its high-surface-area and porosity hold water and nutrients, grab metals/organics and improve soil structure—or get packed into engineered media for filtration and remediation. Produced pathogen-free under high-temperature conditions.

Syngas

The hydrogen-rich syngas is cleaned and fully oxidized in a high-temperature flameless oxidizer. Inside, the 3 T’s—time, temperature, and turbulence—drive complete destruction of PFAS and related fluorinated compounds in the off-gas, so no detectable PFAS is emitted. The result: clean, reliable thermal energy.

Thermal Energy

That thermal energy is recycled back to the PYREG reactor and the dryer, drastically reducing the need for auxiliary fuel after startup and keeping operating costs and emissions low.
