Abstract

In recent years plastic is a key material, fundamental for a large variety of implications. But its large utilization has the direct consequence of the disposal of tons of wastes, that in the major amount cannot be recycled. To pose a solution to the issue of the increasing amount of plastics that are rapidly accumulating all over the world, it is necessary to switch to biodegradable materials. This dissertation is focused on a biodegradable and biobased plastic (polylactic acid, PLA), in order to set free the material from the market and issues of oil, but the PLA is very expensive. For this reason it was added a part of natural component derived from wastes (wheat middling), that acts as reinforcement and decreases the cost of the final material forming a biocomposite. Since their interaction is difficult, the purpose of this dissertation is to improve the affinity between the PLA and the wheat middling.
