Recycling codes can be found on many packages today. Their purpose is primarily to inform retailers and consumers about the packaging material used and its proper use and recycling.
First and foremost, the shortcuts tell consumers how to dispose of a material in order to correctly return it to the recycling loop so that it can actually be recycled.
In addition, the shortcuts also provide useful guidance for making sustainable purchasing decisions. The codes can also be used to check very easily whether packaging can be heated, for example, without releasing substances that are harmful to health.
For sorting facilities, the labels are only important insofar as they support waste separation by consumers. This is because sorting and reuse in the recycling plants themselves is now carried out using modern technologies, such as those based on infrared.
THE STRUCTURE OF RECYCLING CODES
Recycling codes are made up of at least two, but no more than three, components. The two most important elements are:
This is a Link. Lorem ipsum dolor sit amet consectetur adipisicing elit. Provident atque excepturi vel assumenda ea nostrum dolores unde numquam architecto veritatis id animi, quidem temporibus similique.
- The recycling symbol
This consists of three (usually black or green) arrows arranged in the shape of a triangle. It reflects the recycling cycle and is intended to help consumers catch sight of the recycling number as quickly as possible. - The recycling number
It is located in the center of the arrow triangle, refers to the respective packaging material and is therefore the decisive, informative labeling element.
Under the symbol there is often also a supplementary - Material code
This consists of two to four letters, which helps to make the codes easier to read by identifying the specific material group of the packaging material.
LEGAL BASIS
There is no legal obligation to specify recycling codes. This means that the labeling is done on a voluntary basis.
However, the German Packaging Law (VerpackG § 6, Annex 5) does regulate which materials must be identified with which recycling numbers and codes.
