Recycling code: this is what the symbols on packaging mean

A recycling code can help recycling companies to classify and recycle packaging correctly. Nowadays, sorting and recycling in Germany usually takes place less via the recycling code, but rather using modern technologies such as infrared. For consumers, the code can be helpful in making a purchase decision for items such as plastic tableware or packaging material for food and in separating waste.

What does a recycling code look like?

The code consists of the recycling symbol with:

  • 3 arrows, often green, arranged in a triangle
  • a number in the middle of the symbol that identifies the packaging material
  • an additional abbreviation under the triangle that indicates the exact material type.

Specifying the recycling codes is voluntary.
