Antimicrobial Dust Prevention Agent

In response to recent climate warming, an antimicrobial dust prevention agent is being developed to reduce or eliminate airborne dust generated in industrial or construction sites. This agent, derived from Sargassum horneri, a marine waste imported from China or southern regions due to climate change, utilizes antimicrobial functional compounds. Its goal is to create a versatile antimicrobial dust prevention agent applicable beyond industrial and construction sites.

Expected Effects

Due to the rapid increase in sea temperature caused by climate warming, harmful species such as Sargassum horneri have rapidly entered domestic waters from southern regions. As a research effort to address this issue, the nano-complex extracted from Sargassum horneri is synthesized without using toxic organic solvents, alleviating concerns about environmental pollution. Industries that emit a large amount of fine dust, such as iron and steel manufacturing, petroleum refining, and cement production, can potentially use the dust prevention agent for air quality regulation and environmental pollutant management. This is expected to contribute to mitigating the impact of environmental pollution.
