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 ... -
Influence of Cryolite Content on the Thermal Properties and Coalescence Efficiency of NaCl-KCl salt flux
Milani, Veronica; Vallejo Olivares, Alicia; Tranell, Maria Gabriella; Timelli, Giulio (Peer reviewed; Journal article, 2023)Salt fluxes with fluoride additions are necessary for the treatment and recycling of contaminated or oxidized aluminium scrap. This study aims to investigate the effect of cryolite additions on the thermal properties and ... -
LCA of recycling aluminium incineration bottom ash, dross and shavings in a rotary furnace and environmental benefits of salt-slag valorisation
Vallejo Olivares, Alicia; Vallés, Elisa Pastor; Pettersen, Johan Berg; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2024)Recycling aluminium in a rotary furnace with salt-fluxes allows recovering valuable alloys from hard-to-recycle waste/side-streams such as packaging, dross and incinerator bottom ash. However, this recycling route generates ...
