Do you know, what does it actually mean?
It was created in 1970 - part of a contest for art and design students in the US. The Möbius loop better known as the "Recycling" Symbol is now used all around the world; in the public domain, the arrowed triangle is not a trademark.
The symbol means the product might have the potential to be recycled, period. It does not mean that has been recycled or that will be recycled, only that it might have the potential to be recycled.
Sometimes, this symbol comes with a percentage sign inside, which is used to indicate the percentage of recycled material that the product has.
