Characteristic properties and recyclability of the aluminium fraction of MSWI bottom ash
Gökelma, Mertol; Vallejo-Olivares, Alicia; Tranell, Gabriella (Peer reviewed; Journal article, 2021)The increasing use of aluminimum in packaging applications results in many different aluminium-based products ending up in consumer mixed-waste bins. This waste is typically incinerated, generating an aluminium-containing ... -
Compaction of aluminium foil and its effect on oxidation and recycling yield
Vallejo-Olivares, Alicia; Philipson, Harald; Gökelma, Mertol; Roven, Hans Jørgen; Furu, Trond; Kvithyld, Anne; Tranell, Gabriella (Peer reviewed; Journal article, 2021)One of the problems when recycling aluminium is its oxidation and consequent metal loss. This is especially critical for the thin sheet/foil materials used for food packaging applications. Compacting the scrap into briquettes ... -
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 ... -
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 ... -
The effect of thickness and compaction on the recovery of aluminium in recycling of foils in salt flux
Philipson, Harald (Master thesis, 2020)I Norge förbränns mer än 40 000 ton aluminiumförpackningar årligen. Återvinning av denna mängd aluminiumförpackningar skulle spara 1,5 TWh energi och hundratusentals ton av koldioxidutsläpp. Det mycket svårare att återvinna ... -
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, ...
