Processing and Properties of Marine Biodegradable plastics

From the point of environmental protection, the protection of rivers, lakes, seas and oceans is very important. The general problem in the seas and oceans are the discarded plastic products, floating or sunk. Much of the plastics found the marine environment comes from industrial products, consumed or used before being thrown away with their packaging. Plastics are a big threat to the ocean environment for two main reasons. First, because of their volume – they represent 75-80% of marine litter. But also, because of their advantages: light weight – they are easily carried by currents ; and resistance to biodegradation – they build up over time. The need to reduce the quantities of discarded non-degradable plastics in the seas has led to the development of marine degradable materials that degrade completely after a certain time after having been discarded into water. The paper analyses the possibility of processing the marine degradable material using the injection moulding process, the testing of mechanical properties, and the applicability of the material for manufacturing of products that come into close contact with food.
