Adding metal recycling to a new of existing Scanacon acid recycling solution means you are closing the loop, re-circulating not only acid but alloy metals too. The fully automated process will continuously regenerate up to 30 kilograms* of high-value metallic nickel every hour – ready to be fed back into production without ever leaving the plant.
At Scanacon, we accepted the challenge from producers of steel, titanium, and zirconium to help them eliminate environmentally unfriendly waste from their processes. The aim was to reduce environmental impact to close to zero and boost profitability for steel plants.
With a 40-year history in acid pickling chemistry, we have a deep understanding of the problems associated with your pickling operations. Pickling is an expensive, non-core activity, a necessary production step that is messy and difficult to control from a process perspective. It also involves health and safety risks. Although acid used in the process can be recovered to meet environmental legislation, the regulations and demands from authorities are getting tougher every day. The most challenging aspect is that pickling processes generate massive volumes of waste acid and neutralization sludge with a non-recovered valuable metal content.
The overriding question is how can we minimize environmental impact and at the same time boost profitability?
The Scanacon way is recycling valuable metals, acids and water used in the surface treatment process, thus keeping generation of hazardous waste close to zero and minimizing the plant’s environmental impact. Costs related to the handling of sludge are virtually eliminated and profitability increases dramatically.
With Scanacon’s innovative solution, the metals in your waste stream can now be recycled and your plant’s environmental impact from the pickling process can be reduced to almost zero. It's a true game changer for producers of steel, titanium and zirconium.
The system comprises standardized Scanacon core technology, combined with new innovative products developed in-house, in a four-step process, with no sludge produced from neutralization. It has a small footprint and is modularized and scalable. The system is capable of:
The Metal Recycling system for a medium sized installation (2 m³/per hour) is capable of:
* example figures, may vary depending on feed
The system is a sustainability platform for meeting one of the steel industry’s main environmental problems.

1. Pickling process
A typical pickling, chemical milling or etching process bath.
2. Scanacon Acid Recycling system
The Scanacon Acid Recycling system separates the free acid from the dissolved metals and sends the free acid back to the pickling process while the dissolved metals are sent as a weak acidic waste stream.
3. Scanacon Metal Recycling system
The waste stream from the Scanacon Acid Recycling system is treated in the Scanacon Metal recycling process, creating a product of recycled metals and water that can be reused in the process.
4. Recycled metals
Recycled metals, such as Nickel, Chrome and Iron can be sent back and reused in the steel making process or sold on the market.
