Sažetak
In today’s world environmental protection plays an important role. This also includes the rivers, lakes, seas and oceans. The general problem in the seas and oceans, among other things, are the discarded plastic products. Such fl oating plastic products act as absorbers of heavy metals, pesticides, polychlorinated biphenyls (PCBs) and other toxins that then get accumulated in sea animals, and consequently in humans as well. The most common sources of pollution are the ships (35 to 85%), i.e. people who throw various products into the sea, lost fi shermen’s nets and waste from rivers or brought by the wind. The need to reduce the quantities of discarded non-degradable plastics in sea, has led to the development of marine degradable materials that after having been discarded into water (sea, lake and river) degrade completely after a certain time. The paper analyzes the possibility of processing the marine degradable material using the injection moulding process, and also the testing of mechanical properties has been performed. Its degradability in the sea has been tested as well as the applicability of the material for manufacturing of products that come into close contact with food.
