Biodegradable Polymer Materials: Properties, Applications, and Environmental Fate

Popis výsledku v původním jazyce

Plastic materials, in this context especially plastic packaging materials, became a part of our everyday life and greatly improved e.g. food hygiene, shelf life and the overall culture of the food supply chains and retail. On the other hand plastic waste amount and its accumulation reached the scale when it is regarded as alarming by both the public and regulatory bodies. The only solution to this problem is the necessity to constantly build and improve the system of plastic waste separated collection and recycling. Such system has to be able to distinguish different polymer materials to create sufficiently well-defined and economically viable streams of the recycled materials. In some particular applications it seems useful to replace standard polymer materials with the biodegradable alternatives. There are several such basic polymers available which differ in their properties important for their processing and application but also in the way of their environmental degradation. Nowadays all these materials are polyesters of various origins and properties. The design of the final polymer materials can be greatly improved by blending the individual polymers and biodegradable fillers eventually and employing other types of additives like nucleation agents, plasticizers, chain extenders etc. It seems that with the help of these approaches it is possible to finally overcome relatively poor properties of the raw biodegradable polyesters and turn them into useful materials. Above outlined modifications can also deeply influence the biodegradability of the materials which then must be evaluated but they can also be employed to control the rate of the biodegradation in different conditions. It is thus very important to develop a given material for a particular application reflecting all stages of its life cycle from its processing and application to its biodegradation. The ultimate goal of this endeavor is the development of materials with programmed properties during their life cycle.
