| Abstract Scope |
The need to maximize the efficiency in post-consumer aluminum scrap recycling processes is continuously rising in order to achieve sustainable industrial implementation of circular economy practices. The present work investigated the optimization of pre-heating process during the recycling of Used Beverage Cans (UBCs) in a multi-chamber furnace. In particular, aiming to predict the UBC temperature distribution during pre-heating, a numerical model of an industrial furnace was developed considering conduction, convection and radiation mechanisms for heat transfer. A laboratory electric resistance furnace was used to measure the UBC delacquering degree as a function of the temperature. The obtained correlation (Temperature – Delacquering Degree) was then incorporated into the numerical model rendering it a useful tool for evaluating the delacquering process. The model results were validated by industrial scale trials. Finally, the dependence of the UBC delacquering on various industrial-scale process parameters was examined. |
