Circular Materials has secured €11.8 million to expand a process that recovers critical and strategic metals from industrial wastewater, turning a waste treatment problem into a potential source of material for European manufacturing.

The Italian company uses Supercritical Water Precipitation, known as SWaP, to separate dissolved metals from water. It says the process can recover more than 99% of target materials while avoiding the hazardous sludge generated by conventional chemical precipitation.

Waste streams from batteries, semiconductors, aerospace, defence, electroplating, and other metal-intensive industries could provide feedstock. Recovered material may then return to industrial use, while the originating manufacturer reduces the water treatment and disposal burden attached to the same process.

Recycling and urban mining have formed part of European industrial policy for years, so the financing does not introduce a new direction. It moves one recovery technology towards larger commercial facilities as the Critical Raw Materials Act places measurable targets around European extraction, processing, and recycling capacity.

Waste treatment depends on the value left in the water

Industrial wastewater can contain useful metals at concentrations that conventional treatment systems regard primarily as contamination. Existing processes may remove those materials to satisfy discharge rules without preserving them in a form that can be sold or reused.

Circular Materials argues that higher recovery and reduced sludge can change the economic calculation, although each customer’s case will depend on the composition and consistency of the waste stream. A process containing valuable nickel, copper, tin, chromium, or precious metals offers a different return from water carrying low concentrations of cheaper material.

Purity will govern where the output can be used. Semiconductor and battery manufacturers operate to demanding specifications, and recovered material cannot re-enter production merely because the target metal is present.

Contamination, traceability, particle form, and repeatability will determine whether the recovered product commands a premium industrial price or moves into a less demanding application. Certification can take time, particularly where a material affects product safety or long-term performance.

The company already operates an authorised facility in Padua with capacity of around 1,000 tonnes of wastewater a year. Its expansion plans have included a larger Italian plant capable of treating up to 20,000 tonnes, which would test equipment durability, energy consumption, maintenance, and the ability to handle different waste streams without extended reconfiguration.

Public policy can support capacity, but contracts must sustain it

Circular Materials has been selected as a strategic project under the EU Critical Raw Materials Act, opening a route to more streamlined permitting and public finance. That status reflects the project’s potential contribution to European supply, although it does not create the customers needed to keep a commercial plant operating.

Manufacturers must be confident that using the recovery process reduces treatment costs, limits environmental exposure, or secures a valuable stream of material. Buyers on the other side need dependable quality and volume, leaving long-term agreements central to financing further facilities.

The European Innovation Council Fund and EIT RawMaterials have joined private investors because Europe remains exposed to concentrated international supply chains for metals used in electronics, batteries, renewable energy, and defence equipment. New mines and refining plants take years to develop, while industrial waste already contains material that has been imported and processed once.

Recovery cannot replace primary extraction, especially while demand grows, but it can reduce losses and create smaller distributed sources of supply. Where a factory produces a steady waste stream, the material may remain inside a regional manufacturing network rather than leaving Europe as hazardous waste.

Environmental performance must be assessed across the entire process. Lower sludge volumes provide a clear benefit only if energy use, chemical inputs, transport, and equipment requirements do not transfer a large part of the burden elsewhere.

Centralised plants can concentrate expertise and processing equipment, while on-site or modular systems may reduce transport and keep recovered material closer to the originating factory. Distributed deployment requires stronger automation, remote monitoring, and maintenance support, creating a different operating model from a single large treatment centre.

Circular Materials’ strategic-project announcement sets out its existing capacity and planned expansion. The new financing gives the company more room to prove that high recovery rates can be repeated economically across industries rather than achieved only in a controlled process.

Commercial progress will become visible through operating costs, uptime, material quality, customer agreements, and the quantity of imported supply credibly displaced. Europe already knows that industrial waste contains useful resources; Circular Materials now has to show that retrieving them can support a durable manufacturing business.
