Biodegradable mulch films (BDMs), distinguished by their extensive application potential and ecological friendliness, are progressively supplanting traditional mulch film and considered as a highly promising approach to address “white pollution”. China has witnessed notable advancements in the production technology of BDMs in recent years, establishing a strong foundation for their large-scale manufacturing and widespread application. Despite the great prospects of BDMs, the complexity and controllability of their degradation process, alongside their potential impacts on the eco-environment, remain highly concerned. This paper comprehensively analyzes five promising polyester and polycarbonate-based BDMs and delves into the primary degrading microorganisms and their degradation mechanisms. Furthermore, this paper summarizes the current research regarding the impacts of BDMs on the soil environment. This review aims to lay a theoretical foundation for discovering efficient microbial degraders, pinpointing key rate-limiting steps in degradation, and enhancing long-term ecological effect studies, thus providing new perspectives and solutions for the large-scale and safe utilization of BDMs.
