How does a silver recovery system in film processing work? Follow the four steps Electrometal uses to recover silver from X‑ray films and recycle every component.
Old X‑ray films may look like simple sheets of plastic, but every radiograph contains silver, a precious metal that can be recovered and put back on the market. Recovering it takes a precise process, designed to extract the silver while permanently destroying the patient information the films carry.
At Electrometal, this silver recovery system in film processing has been refined over nearly 50 years. Everything happens in-house, at our two plants in Canada, with no subcontractors involved. In this article, we explain where the silver in your X‑ray films comes from, then walk you through each of the four steps that turn an old film into recycled silver and plastic.
An X‑ray film is made of two layers. The base is a thin sheet of PET plastic, which gives the film its strength and makes up most of its weight. On top of it is the emulsion, a fine coating that contains silver. When the film is exposed and developed, that silver forms the dark areas of the image.
In other words, the image you see on a radiograph is literally made of silver. As long as the film exists, so does that silver, which is why archives of old X‑ray films are a real resource rather than simple waste.
The same principle applies to other types of film. Silver halide film, lithographic film used in printing, DryView film, industrial film and non-destructive testing (NDT) film all contain silver that can be recovered through X‑ray film recycling.
Recovering silver from X‑ray films means separating materials that were designed to stay bonded together. Our process does it in four steps, each with a specific role.
When your X‑ray films arrive at our plant, our team receives and checks every shipment. The films are then sorted from everything that came with them, such as the paper envelopes they were stored in. Those envelopes don't go to waste: the paper is recycled too. Careful sorting matters at this stage, because the cleaner the films that enter the process, the purer the silver and plastic recovered at the end.
The X‑ray films are then shredded and reduced to small granules. This step plays two roles at once. First, it permanently destroys all patient information: once granulated, a film no longer holds any name, date or image, and there's no way to reconstruct them. Second, it prepares the material for the next step. By breaking the films into small pieces, granulation exposes much more of the silver-bearing emulsion, which makes it easier to separate from the plastic.
This is where the silver is actually separated from the plastic. The granules go through a washing process that detaches the silver-bearing emulsion from the PET base. On one side, the silver is collected so it can be recovered. On the other, clean PET granules are left behind, ready for their second life.
The recovered silver is refined until it reaches maximal purity. At that level, it returns to the market as a precious metal in its own right, ready to be used again without the environmental footprint of mining new silver. The clean PET is turned into high-quality recycled PET plastic flakes that manufacturers use as a raw material, from packaging to textiles. At the end of the process, nothing from your X‑ray films ends up in a landfill.
Knowing how silver is recovered from your X‑ray films isn't just a technical detail. It tells you whether your X‑ray film disposal is handled properly.
First, it guarantees confidentiality. Because every step takes place in our own facilities, your X‑ray films never pass through a third party, and patient data is destroyed by our in-house team.
Second, it's a complete form of recycling. The silver, the PET plastic and even the paper envelopes are all recovered, so your archives are fully recycled, not just partially.
Finally, it gives your X‑ray films value. Because the silver can be recovered and refined, Electrometal makes you a purchase offer for your films, and the pickup is free wherever your organization is located.
Whether you have a few boxes of X‑ray films or an entire archive room, Electrometal can put its silver recovery system to work for you. Recycling your films is the best way to recover their silver, protect your patients' or clients' data and free up space, all in a single step.
