ABSTRACT The efficient recycling of plastics and polymers is a focal point within the development of circular chemistry. In this realm, the development of new types of recyclable‐by‐design polymers plays a crucial role in answering a growing need for plastic formulations that can build on this intrinsic feature while using renewable resources. Within the large and diverse family of engineering polymers, polycarbonates (PCs) play an essential role as modular components for many consumer products. Challenges related to a more sustainable production of PCs and their end‐of‐life disposal have created incentives towards a more responsible use and reuse of these macromolecules. This review focuses on key aspects that should guide future PC development, with both a mechanistic understanding of controlled degradation and identifying efficient depolymerization approaches being the major outcomes. In addition, emerging classes of polycarbonates, such as heteroatom‐containing ones are highlighted and discussed.
