Along with economic development and urbanization, the amount of solid waste generated in Vietnam has steadily increased at an annual rate of about 10% (Trương, N.T., & Halonen, I., 2018). In 2019, the amount of domestic plastic waste discharged nationwide was 64,658 tons/ day, an increase of 46% compared to 44,000 tons/ day in 2010 (MoNRE, 2019). Nonetheless, only 15% of the country’s generated plastic waste is recycled or reused (NPAP, 2020). The rest ends up mainly in landfills, open dumpsites, incinerators, or in the environment.
