As previously explained, the very nature of plastic (strong bonds within the polymer and high molecular weight , which confer resistance to degradation Palmisano and Pettigrew, 1992; Zheng et al., 2005) makes it extremely hard to degrade, causing it to stay for very long periods into the environment. This is due to the great versatility and high resistance of this polymers towards environmental processes. Following different mechanisms, degradation of these polymers can be distinguished between biotic or abiotic, depending on the different mechanisms that make it possible \citep{Klein_2017}. During these mechanisms, that depend on chemical, biological or mechanical processes, the plastic is converted in smaller molecular units and can also be completely mineralized \citep{Eubeler_2009}.
