Eco-Friendly Microplastic Removal Using High-Performance Ultrasonic Welding Technology and Biodegradable Filters

초록

Recently, the contamination of microplastics in the coastal waters of Incheon has emerged as a serious environmental issue, contributing to water pollution and increasing greenhouse gas emissions. These microplastics cause long-term damage to marine ecosystems, further degrading water quality. Traditional methods for removing microplastics are costly and inefficient, making them impractical for large-scale applications, with the potential to cause additional environmental issues during the treatment process. This study proposes an innovative approach using high-performance piezoelectric ultrasonic technology to address this challenge. By utilizing ultrasonic vibrations, microplastics are condensed and fused into larger particles, making them easier to filter using biodegradable cellulose-based filters. These filters, composed of eco-friendly materials, are naturally degradable and offer significant environmental advantages over conventional synthetic fiber filters. This technology significantly improves the cost-effectiveness and efficiency of microplastic removal by condensing small plastic particles via ultrasound, overcoming the challenges posed by the filtration process. Furthermore, this approach is expected to contribute not only to the improvement of Incheon’s marine environment but also to the reduction of water pollution and carbon emissions. In the long term, this solution is anticipated to play a vital role in the restoration of the local marine ecosystem, while reducing social and environmental costs. In conclusion, the proposed method of condensing and removing microplastics using high-performance piezoelectric ultrasonic technology presents a sustainable alternative to existing inefficient treatments. It is expected to contribute significantly to reducing carbon emissions and solving marine pollution in the Incheon region.
