The European Union has enacted a range of directives with the objective of elevating recycling rates. Despite these legislative efforts, a significant proportion of plastic materials continue to contribute to waste accumulation. This scenario not only poses environmental challenges, but also represents untapped economic opportunities in the realm of plastics recycling. The intricacies of plastic types and the corresponding recycling methods are multifaceted. Gaining a better understanding of these elements can provide invaluable insights that can reshape the perception and use of plastics. In this chapter, we will delve into these complexities, drawing on the authoritative expertise of Professor Daniel Schwendemann, a leading figure in the domain of plastics processing. He provides insights on key considerations and challenges inherent to plastics recycling.
