Circular materials

We're revolutionizing waste management standards with our innovative technology. It transforms Waste to Energy (WtE) facilities by efficiently handling fly ash, Air Pollution Control (APCr) residues, and recovering valuable resources like minerals, gypsum, metals and specific salts (CaCO3, KCl, NaCl).

Our contribution to circularity

Experience firsthand the depth of our unwavering dedication as it harmoniously aligns with the principles of creating a circular economy, maximizing resource efficiency, and effectively avoiding the generation of hazardous waste.

How it works

The HaloSep process efficiently manages hazardous waste from energy recovery.

It separates waste into three fractions, treats hazardous components, recycles valuable materials, and ensures responsible disposal, minimizing environmental impact.

Recycled fly ash

Treated fly ash from the HaloSep process now officially classified as non-hazardous

The results from these tests verified the non-hazardous nature of the treated fly ash concerning key elements in the classification process.
