Evaluating Pollution from Aquaculture Materials and Developing Sustainable Alternatives to Reduce Marine Environmental Impacts: A Case Study in Vietnam

This study aims to assess the status of marine pollution associated with aquaculture activities in Vietnam, emphasizing the contribution of primitive aquaculture materials— such as Styrofoam floats, wooden cages, and low-grade plastics—to environmental degradation. The research analyzes the pathways through which these materials generate microplastics, chemical leachates, and solid waste, exacerbating coastal and marine pollution. Furthermore, in this work has been proposed that the promising approach highlights the importance of sustainable material innovation, particularly the development and application of high-density polyethylene (HDPE) and other eco-friendly composites, as a strategic solution to mitigate the adverse environmental impacts of aquaculture. The development of sustainable HDPE materials aims to address the urgent challenges of marine plastic emissions from conventional aquaculture practices. Specifically, this study will propose a sustainable HDPE pipe production solution through a technological approach that blends UV-resistant and anti-aging additives at an optimal ratio. The goal is to synthesize durable HDPE materials suitable for application in sustainable marine aquaculture. By integrating technological advancements, policy recommendations, and local implementation strategies, this study provides a scientific foundation for promoting environmentally responsible and economically viable marine aquaculture in Vietnam.
