A new solution for the treatment of dye-containing wastewater in the textile industry.
80% of textile factories in Vietnam violate the National Environmental Regulation, making textile the third most polluting industry in the country, following mining and agriculture. The fundamental challenge is the inefficient and costly processing of dye water using chemical precipitation. I researched a graphene-based nanocomposite and led a team to develop a solution to treat dye water with only the reusable nanomaterial and UV light.
