Biodegradable polymers are promoted as an environmental solution to plastic pollution. However, their degradation in managed and unmanaged environments is not well understood. Thus, humankind does not understand the end-of-life management possibilities nor the environmental impact of these polymers if they are released into the environment. The fact that biodegradable polymers are blended together to achieve functionality introduces further uncertainty for biodegradable plastic waste management and environmental impact. The aim of this study is to understand the biodegradation of individual polymers and their blends in managed and unmanaged environments.
