Effect of Compaction and Thermal De-coating Pre-treatments on the Recyclability of Coated and Uncoated Aluminium
Vallejo-Olivares, Alicia; Høgåsen, Solveig; Kvithyld, Anne; Tranell, Gabriella (Journal article, 2022)Scrap pre-treatments, such as compaction and thermal de-coating, are standard industrial practices for recycling aluminium post-consumer scrap. This study compares the recyclability of a coated and uncoated 8111 alloy under ... -
Effects of Compaction and Thermal Pre‑treatments on Generation of Dross and Off‑Gases in Aluminium Recycling
Vallejo Olivares, Alicia; Gertjegerdes, Tom; Høgåsen, Solveig; Friedrich, Bernd; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2023)Organic coatings are a challenge for aluminium packaging recycling since they tend to increase the re-melting metal losses. A solution is de-coating the scrap via a thermal pre-treatment to burn-off the organics before ... -
The effect of compaction and thermal treatment in the recovery of coated aluminium scrap through FTIR off-gas analysis and remelting in molten heel
Høgåsen, Solveig (Master thesis, 2022)Økt fokus på global oppvarming har medført at alle teknologiske sektorer ser etter løsninger på problemer tilknyttet energibruk og utslipp. Aluminiumsektoren har de siste tiårene opplevd en økt primærproduksjon noe som ... -
Thermal De‑coating Pre‑treatment for Loose or Compacted Aluminum Scrap and Consequences for Salt‑Flux Recycling
Vallejo-Olivares, Alicia; Høgåsen, Solveig; Kvithyld, Anne; Tranell, Gabriella (Peer reviewed; Journal article, 2022)In aluminum recycling, thermal de-coating pre-treatments remove moisture and organic contamination before re-melting. If the scrap is compacted into bales or briquettes before the thermal treatment and re-melting processes, ...
