The VLU Faculty of Technology has completed a project to investigate plastic waste generation rate, volume, and composition in Phu Quoc

(VLU, 16/11/2021) The research group of Van Lang University's Faculty of Technology, led by Dr. Nguyen Thi Phuong Loan and Ph.D. candidate Le Minh Truong, officially completed the project "Survey on the generation rate, volume, and composition of plastic waste on Duong Dong river, Phu Quoc" in October 2021. This is a project within the "Mitigating Marine Plastic Debris in Vietnam" program, which was commissioned by the World Wide Fund for Nature in Vietnam and assigned to the Faculty of Technology - Van Lang University.

In general, the "source – to – sea approach" is a six-step cycle that focuses on six major flows of matter, including water, soil, pollutants, biomes, materials, and environment services, for designing, planning, implementing, and evaluating projects and programs that support management from problem source to ocean.

The project "Study on the rate, volume, and composition of plastic waste in the Duong Dong River, Phu Quoc" employs a Waste Flow Diagram (Renaud et al. 2018) to estimate the amount of plastic waste dumped into the sea from the Duong Dong River, completing the first step of the project's source-to-sea description. Plastic waste floating in the Duong Dong River in Duong Dong City, Phu Quoc Island, is the primary material flow studied in this study. The findings will assist local management agencies in (1) developing a plan for waste collection and disposal (including plastic waste) from hotspots. (2) Reducing the amount of plastic waste entering water sources and being discharged into the sea, and (3) completing the solid waste management system of households along the river, as well as boats and vessels moored in the Duong Dong River.

With regard to the results, this report has been compiled from primary data sources to assess the current status of plastic waste in the Duong Dong River and to identify hotspots, sources, generation rates and composition of plastic waste. plastic waste. The project also conducted a sociological survey and used with secondary data (WWF Vietnam and USAID 2018) for balance and estimate the amount of plastic waste that is discharged into the sea through different transport routes. Due to the restrictions of survey conditions (short survey time, solid waste survey within the river is tormented by wind regime, tidal regime, and lifestyle and tourism activities are being stricken by COVID-19) and therefore the survey is predicated on a sampling, the info obtained from the survey is suggested to be used as an indicator instead of a highly reliable statistic.

Recommendation: The research team proposes the following solutions to minimize the release of plastic waste from the ocean.

  • Add solid waste collection lines to fully collect wast from riverside homes that do not yet have access to local waste collection systems.
  • Set up reclaimed land concentrated on the shore and scattered on both sides of the river to provide easy access for people living on board. To strengthen and complement the work of the solid waste collection team of the Phu Quoc Public Works Management Council. In particular, in order to minimize the burden of collecting garbage collected in the river, the responsibility of collection team is collecting the garbage generated by approaching ships and boats moored in the river. Local authorities must provide free trash cans on boats. Local authorities develop policies and sanctions for the direct discharge of waste into rivers, approve waste collection teams from the Public Works Management Board, and establish a team of inspectors to inspect and oversee.
  • Disseminate people to raise awareness and knowledge of the waste decomposition process.
  • Improve river waste collection facilities.
  • Hazardous wastes from rivers are well collected.
