| Abstract Scope |
Aluminium is often applied in packaging due to its strength and preservative capability. However, it is hard to be recycled due its thickness. In northern Europe, cream cheese, caviar, mayonnaise are stored in toothpaste like aluminium tube to extend food preservation. This paper focuses on evaluation of the recyclability of aluminium waste tubes for food from the aspect of the tube thickness, the customer habit, food residue, and pre-treatment with measurement of yield and analysis of metal quality. It was concluded that aluminium food tube is recyclable. Food residue reduced the yield from around 90% (non-used) to 50% (with 4% food residue). The change of thickness of tube did not influence the recycling yield considerably. While, less aluminium was consumed to produce thin tubes. Most of the food reside was located around the shoulder area. This calls for improvement on tube design. |
