Zero-Waste Metal Recovery System for Industrial Wastewater Treatment

environmentPilotedTRL 7

Imagine a high-tech filter that doesn't just clean dirty water but turns the pollutants into a valuable powder. Instead of creating a toxic sludge that you have to pay to bury in a landfill, this system uses special water conditions to make metals drop out as a solid. It's like turning a waste problem into a mining opportunity right inside the factory.

The business problem

What needed solving

Surface treatment companies lose over 95% of metals in wastewater and are forced to pay for the disposal of toxic sludges in hazardous waste landfills.

The solution

What was built

An automated operational system using Supercritical Water Precipitation (SWP) to turn dissolved metals into a reusable solid powder.

Who can put this to work

Metal Finishing
SME
Target: Surface treatment SME

If you are a surface treatment SME dealing with toxic chromium or nickel wastewater—this project developed a Supercritical Water Precipitation system that recovers over 99% of dissolved metals. This eliminates the need for hazardous waste landfills and provides high-purity raw materials for reuse.

Electronics Manufacturing
mid-size
Target: PCB and component manufacturer

If you are a manufacturer dealing with precious metal loss in process water—this project developed a modular reactor that precipitates metals as a solid powder. It allows you to recover critical raw materials like copper and nickel with recovery rates exceeding 99%.

Chemical Processing
enterprise
Target: Industrial wastewater plant operator

If you are a plant operator dealing with the high cost of disposing of toxic sludges—this project developed a chemical-free treatment process. It replaces traditional sludge-generating methods with a system that produces clean water and reusable metal powders.

Frequently asked

Quick answers

How does this affect operational costs?

Operating costs are drastically reduced because the process requires no chemicals and eliminates the need to pay for hazardous waste disposal in authorized landfills.

Can this be scaled for larger factories?

Yes, the technology features a modular design that allows multiple units to be combined to improve energy efficiency and reduce capital intensity.

Is the technology protected by intellectual property?

Based on available project data, Circular Materials has developed and patented the sustainable technologies and processes used in this system.

How does it integrate with existing wastewater flows?

The system uses a reactor that continuously mixes wastewater with supercritical water to precipitate metals as a solid powder, which is then easily separated from the water.

What is the timeline for deployment?

Based on available project data, the project period ran from 2022-04-01 to 2024-09-30, moving the technology from concept to an automated operational system.

Consortium

Who built it

The project is led by a single Italian SME, Circular Materials SRL, which acted as the sole partner. This 100% industry-led consortium indicates a strong focus on commercial viability and direct market application rather than academic research.
