Remove organics
Designed for paint, ink, paper, plastics, oil and other coatings attached to aluminum scrap.
Used beverage cans carry organic surface materials that can create smoke, flame, dust-control load, slag and aluminum burning loss when fed directly into a furnace. Chouno combines size reduction and low-oxygen thermal de-coating to move contaminant removal before remelting.
UBC decoating project overview
| Feed | Baled, loose or pre-shredded used beverage cans and other coated aluminum scrap, subject to feed review. |
|---|---|
| Core process | Controlled feeding, size reduction, low-oxygen thermal decoating, volatile-organic combustion, heat reuse and discharge conveying. |
| Target output | Cleaner, more consistent aluminum fragments prepared for the selected remelting route. |
| Line sizing | Configured from feed bulk density, coating load, moisture, hourly throughput, operating schedule and furnace demand. |
| Engineering output | Recommended process route, equipment scope, plant interfaces, utility basis and remaining test requirements. |
Improve furnace feed
Cleaner and more uniform fragments help stabilize downstream remelting and reduce coating-related load.
Integrate the line
Shredding, thermal treatment, circulation, combustion, dust-control interfaces and conveying are evaluated together.
How the process works
Prepare
Inspect feedstock, coating content, dimensions and contamination.

Published performance context: Chouno's technical content states that UBC de-coating before remelting can improve molten-aluminum recovery by approximately 5%–10% compared with direct melting without de-coating. Actual results depend on feed composition, coating content and operating conditions.
Real material and installation context
Typical feed materials
Used beverage cans

Frequently asked questions
Why decoating UBC cans before remelting?
Removing organic coatings before the furnace can reduce smoke, flame, slag and aluminum oxidation while improving feedstock consistency.
Which contaminants can the process address?
The process is designed for paint, printing ink, internal lacquer, paper, plastics and oil on aluminum surfaces.
Can the line be added before an existing furnace?
A retrofit can be evaluated after reviewing the furnace feed method, available layout, conveying elevations, utilities and gas-treatment interfaces.
What determines line capacity?
Feed form, bulk density, coating load, moisture, target output condition, operating schedule and furnace demand are evaluated together.
