We often discuss the significance of correct waste segregation, and this is particularly true for aluminium foil. Aluminium is an ideal material for recycling because processing it consumes considerably less energy than producing new material. Therefore, properly segregating aluminium foil can have a significant environmental impact.

Where to dispose of aluminium foil? It depends

There is no single answer to where to dispose of aluminium foil. It requires careful individual assessment. If the foil is relatively clean or only slightly dirty, it should be placed in the container for metals and plastics, where materials suitable for recycling belong. Compacting the foil into a larger ball can further facilitate the process.

If the foil has been used, for instance, in baking and is soiled with grease or burnt residues, the situation changes. Such contaminated foil can spoil other materials and impede their processing. It should be discarded with mixed waste.

When should you be careful with aluminium foil?

Aluminium foil is generally safe, but there are occasions when it's advisable to be cautious or to opt for alternatives like parchment paper or glass containers. What risks are involved, and when should you exercise particular care?

  1. During baking. High temperatures can cause aluminium to leach into food.
  2. It is not suitable for all products, especially acidic ones, such as citrus fruits, tomatoes, or vinegar. These can accelerate the corrosion of aluminium, increasing the risk of metal leaching into food.
  3. Prolonged contact. The longer food remains in contact with aluminium foil, the higher the risk of aluminium leaching.
  4. Greasy dishes. Fat can react with aluminium, forming harmful compounds.
