Circular Materials Turns Industrial Wastewater Into a Critical-Metals Mine

Highlights

• Circular Materials deploys SWaP (Supercritical Water Precipitation) technology to recover critical metals from industrial wastewater at precipitation rates exceeding 99.9%.
• Europe loses an estimated 12,000–15,000 tonnes of mixed critical metals annually through industrial wastewater; the U.S. opportunity may be three to four times larger.
• Unlike conventional recyclers, Circular Materials is paid to take hazardous wastewater and then earns additional revenue selling recovered metals, reducing commodity-price risk.
• The company holds Strategic Project status under Europe's Critical Raw Materials Act and plans to expand to at least three or four U.S. sites.
• Its Ferrara facility targets approximately 20,000 tonnes of wastewater and 1,000 tonnes of mixed metals per year.

What if one of the West’s richest untapped critical-mineral resources is not underground—but flowing through industrial pipes? In a new Rare Earth Exchanges® (REEx) podcast (opens in a new tab), hosts Daniel O’Connor (opens in a new tab) and Dustin Olsen (opens in a new tab) speak with Marco Bersani (opens in a new tab), CEO and Co-Founder of Circular Materials, (opens in a new tab) an Italian critical-metals recovery company deploying SWaP™ (Supercritical Water Precipitation) technology (opens in a new tab).

Circular Materials targets industrial wastewater containing extraordinary metal concentrations—typically 1%–10%, or 10,000–100,000 ppm—and reports precipitation rates consistently exceeding 99.9% across highly variable metal-bearing waste streams.

The scale could be substantial. Bersani estimates Europe currently loses roughly 12,000–15,000 tonnes of mixed critical metals annually through industrial wastewater, including nickel, chromium, and copper. Preliminary company estimates suggest the U.S. opportunity could be three to four times larger.

The economics may be even more disruptive. Unlike conventional recyclers that purchase feedstock, Circular Materials is paid by manufacturers to take hazardous wastewater and then generates additional revenue by selling recovered metals. Bersani says the disposal business alone can be profitable, potentially reducing exposure to commodity-price volatility.

The company currently operates an authorized facility near Padova, Italy, and plans a much larger Ferrara operation targeting approximately 20,000 tonnes of wastewater and 1,000 tonnes of mixed metals annually. Circular Materials has also been designated a Strategic Project under Europe’s Critical Raw Materials Act and plans eventually to deploy at least three or four sites in the United States.

REEx Insight: The strategic breakthrough is not simply recycling—it is converting an environmental liability into high-grade, negative-cost feedstock. If scalable, industrial wastewater could become a distributed urban mine already sitting inside Western manufacturing infrastructure.
