Information on NT Recycling's Pilisjászfalu Technology Precise Technical Interpretation of the Term "Black Mass"

🔍 Recently, several questions and misunderstandings have arisen regarding the types of materials NT Recycling processes at the Pilisjászfalu plant, particularly concerning the use of the term "Black Mass." We wish to clarify this clearly, comprehensibly, and on a professional basis.

What do we NOT process? The NT Recycling Pilisjászfalu plant does not process:

Lithium-ion batteries containing electrolyte,

Charged ("active") cells or batteries,

Used or dismantled (end-of-life) batteries,

Black mass originating from complete battery cells.

⚙️ What do we actually process? The Pilisjászfalu technology exclusively processes manufacturing waste generated BEFORE the filling of electrolyte during battery cell production. These materials:

Do not come into contact with electrolyte,

Do not come into contact with organic solvents,

Are in a dry state,

And were never parts of active cells. Typical processed materials:

Cathode foil,

Anode foil,

Dry cell components.

⚠️ Technical clarification of the term "Black Mass"

In the permit application documentation, the term "Black Mass," frequently used in technical literature, appears referring to the black powder generated during processing. However, this term has been taken out of context and interpreted misleadingly. It is important to emphasize:

🔹 The black powder appearing in the Pilisjászfalu plant is NOT identical to the black mass originating from complete battery cells.

What is the difference? The dry black powder generated in the Pilisjászfalu technology contains:

Metal oxide crystals (cathode active material),

Graphite (anode material).

It does NOT contain:

Electrolyte residues,

Non-volatile components of the electrolyte,

Organic solvents,

Decomposition products.

In contrast, black mass from the processing of whole cells would contain materials that have contacted electrolyte, which is not part of the Pilisjászfalu project.

🔥 Why is there no carbonizing furnace? During the technological planning of the Pilisjászfalu plant, a conscious decision was made that:

No carbonizing furnace will be included in the system The reason for this is that:

Carbonizing furnaces operate at high temperatures,

Significant gas emission occurs during their operation,

Their energy demand is extremely high,

And they are justified only in the case of materials contaminated with electrolyte. Since the processed materials have never come into contact with electrolyte, such equipment is unnecessary.

🛡️ Safety and environmental consequences As a result of the chosen technology:

There is no high-temperature technological unit,

There is no electrolyte evaporation,

There is no significant gas formation,

The risk of fire and accidents is lower,

The processing takes place via a closed, dry, mechanical process.

📌 ummary

Only dry manufacturing waste not contacted by electrolyte is processed

We do not process complete battery cells

We do not process used or electrolyte-containing batteries

There is no carbonizing furnace

There is no high-temperature process

The composition of the generated black powder differs fundamentally from black mass derived from complete cells
