Obiettivi dell'insegnamento

The Course aims at making students aware of the basic concepts of sustainable polymers, with the chemistry as the fil rouge.

The Course wants to stimulate the interest and to allow the understanding of such a relevant subject: the sustainability of so important materials for the human life as the polymers.

An objective of the Course is to give to students the fundamental concepts about: polymers, wastes in the environment, the meaning of sustainable, green and circular, the teaching of nature for circular materials, the environmental aspects of traditional polymers, biopolymers as bioplastics and bioelastomers, with examples of largely used products such as a tyre.

An objective of the Course is to give to students updated instruments to deal with the aspect of polymer sustainability.

Moreover, the Couse wants to allow the students to establish correlations between the practical aspects and the theoretical interpretations.

Last, but really not least, the Course wants to put the students in the position to become protagonists in this field, tackling criticalities and promoting innovation.
