Polymer matrix composites are in high demand in many industries, including wind turbine blade manufacturing, pressure vessel manufacturing, and aerospace. In order to reduce unsustainable deconstruction that harms the environment and the potential litigation risk associated with the reintroduction of uncertified salvaged components to the aviation market, flight vehicle manufacturers have started collaborating with the recycling sector. Polymer matrix composites have strong mechanical qualities that make them appealing for a wide range of applications, but because of their heterogeneous nature, recovering composite waste is challenging. This paper compares various polymer-matrix composites (PMC) waste recycling techniques utilizing a multi-criteria decision-making approach and a literature study (MCDA). PMC waste recycling is becoming more popular, much work needs to be done to build a widespread, efficient system that is both financially sustainable and produces the highest-quality recovered materials.
