“Biobased is both a material and a product property. It describes that the carbon atoms – in contrast to fossil ones – are taken from nature in our time, thus they are ‘bio’.”
The principle of sustainability finds its beginning in forestry: only the amount of trees that can grow again should be removed from the forest.
A transfer to the use of bio-based plastics is made here:
“The societal benefit of bio-based plastics is to provide for the time “after oil”. […] Another reason to use renewable raw materials is the shortage of oil. Since around 2006, fewer new oil deposits have been found than old ones have dried up.”
