The global production and consumption of plastics, as well their deposition in the environment, are experiencing exponential growth. In addition, mismanaged plastic waste (PW) losses into drainage channels a growing source microplastic (MP) pollution concern. However, complete understanding environmental implications throughout life cycle is yet to be fully understood. Determining potential extent which MPs contribute overall ecotoxicity possible through monitoring PW release MP removal during remediation. Life assessments (LCAs) have been extensively utilized many comparative analyses, such comparing petroleum-based plastics with biomass single-use multi-use alternatives. These typically yield unexpected or paradoxical results. Nevertheless, there still paucity reliable data tools for conducting LCAs on plastics. On other hand, impact so far not considered LCA studies. This due absence inventory-related regarding releases characterization factors necessary quantify effects MP. Therefore, this review paper conducts comprehensive literature order assess current state knowledge impacts that occur along strategies management LCA.
