A survey conducted by Statista in 2016, shows the behaviour of how Germans handle the paper and glass waste. As you can see, glass waste is something a concerned topic and need to be disposed properly on a regular account.
In my opinion, behaviour analysis of German shows the attitude of disposing the waste depending upon each of their attitude. There is no attitude shown towards not disposing the waste, shows a strong quality towards the cleanliness attitude and to properly dispose the waste. The neatness and cleanliness show a strong character in them to follow the rules of cleanliness properly, daily and may be not on a regular basis, but nobody said No to such disposable topic or not interested in handling the waste.
