The global demand for aluminium and aluminium alloy products is increasing. When used in the automotive sector, this material can facilitate lower fuel consumption (less CO2 emissions), enhanced human safety and can easily be inte grated in modern low-weight, clean energy engine design transport vehicles. Since secondary aluminium can be produced at significantly less energy consumption (only 5% of primary metal production), it is obvious that recycling and up-grading secondary met al to high quality alloys is influencing the total spent energy.
Hence, aluminium scrap accumulated in the market represents a very significant bank of energy and natural source. Due to these facts, it is important to develop real flow path models for th e metal recycling cycle. The present project aims to develop such flow path models and from detailed laboratory studies one will achieve new results for improved remelting techniques at higher output and less pollution from hazardous gas emissions. Other goals will be to compare two different recycling routes (remelt vs. direct solid state recycling) and generally, to improve in the direction of sustainable societies.
