A survey conducted by Statista in 2016, shows the behaviour of how Germans handle waste disposal. As you can see, glass waste is a concerned topic and need to be disposed of properly on a regular account.

In my opinion, behaviour analysis of German shows the attitude of disposing of the waste depending upon each of their attitudes.
There is no attitude shown towards not disposing of the waste, shows a strong quality towards the cleanliness attitude and to properly dispose of the waste.
The neatness and cleanliness show a strong character in them to follow the rules of cleanliness properly, daily, and maybe not on a regular basis, but nobody said No to such disposable topics or not interested in handling the waste.
