Abstract:
As a consequence of its multifunctional characteristics, plastic plays nowadays an important part in our life. Because of its durability plastic stays in the environment a long time after its discarded and finds its way into the ocean more frequently (UNEP, 2016). Therefore, scientists are searching for new utilisation methods for plastic and pyrolysis is one of them (Pinto et al., 1999). The aim of pyrolysis is to gain a liquid and solid energy source. This can be used thermally or energetically to run an engine (Kaltschmitt et al., 2009). The resulting gas from the process can be used as fuel to fire the system (Martens, 2011). This process takes place in the absence of oxygen and in a temperature range between 400°C and 800°C (Scholz et al., 2001). This thesis includes a description of plastics, sources and distribution of marine litter and shows an overview about thermo-chemical processes. In the course of this work the pyrolysis process was chosen for conducting experiments with two different kinds of feed. The first feed is a plastic mixture and the second is plastic found in samples of seawater. For both feeds a mass balance was created in order to make them comparable and to generate knowledge about the potential of marine litter. Due to a great share of inert material, the marine litter sample produces less oil/wax and gas than the plastic mixture sample. The results demonstrate that the potential from both feeds is highest at 525°C oven temperature. This shows pyrolysis is an adequate recycling method for marine litter.
