4D Scavenger®

First technology for selective and cost-efficient recovery of dissolved metals and nutrients from industrial waters

WHY?

Turning industrial water from cost to value

Mining, metals, chemicals, and energy industries spend billions annually on wastewater treatment — while valuable metals like copper are lost to sludge in the process.

Our selective separation technology changes this. By recovering metals directly from industrial water streams, wastewater becomes a source of revenue. The result: lower treatment OPEX, new income streams, improved water reuse, and stronger ESG performance.

OUR SOLUTION

4D Scavenger®

Superior technology for extracting dissolved metals and nutrients from industrial process and waste waters.

⛏ VALUE RECOVERY

Recover critical and strategic raw materials hidden in industrial waters

📈 PROCESS OPTIMIZATION

Remove dissolved impurities that negatively affect process performance or product quality

💧 COMPLIANCE & COST OPTIMIZATION

Polish industrial waters to meet discharge, reuse or internal quality targets

MANUFACTURING METHOD

Enhanced performance through 3D printing

We use selective laser sintering to produce 4D Scavengers®, chemically functional porous filters. This unique method enables virtually limitless control over both chemical composition and physical structure.

The small particle size and uniform porous structure promote faster reaction kinetics, resulting in:

Enhanced selectivity toward target elements
Increased effective capacity for capturing target ions

IP is protected by 6 patent families.

In standard ion exchange process, the target ions are exchanged with ions of the same charge (e.g. Na⁺ ↔ Ca2+).

CHEMICAL PRINCIPLE

Ion exchange reactions behind recovery

Any high–melting, non-soluble material can provide 4D Scavenger’s chemical functionality. Ion exchange (IX) is typically used for its efficiency, reusability, and scalability.

Our technology overcomes key limitations of conventional IX, including:

High operating costs
Poor performance in complex or dilute waters
High chemical use and waste generation
Limited effective capacity

A technology ready for use

4D Scavenger® is not just a concept – it’s commercially available solution in active industrial use. It has been tested and piloted across key industrial sectors, proven effective for the extraction of more than 15 ions – including Cu, Li, Co, Ni, Zn, Cd, Pb, As, N, P and REEs, and we have delivered our first fully 4D Scavenger®-based industrial-scale system.
