Reply to comment by YouAreGenuinelyDumb in Scientists have shown how toxic dyes can be filtered out of wastewater using the method and material developed by the group. The procedure uses sunlight as a catalyst and doesn’t involve any pressure or heat. It can remove 80 percent of dye pollutants in wastewater. by Wagamaga

80% may not be an improvement over what currently exists in developed nations with strict pollution controls, but could be a vast improvement over places that are currently not doing anything.

I’d would be surprised if developed nations allowed as much as 20% of all pollutants from toxic dyes pass through untreated.

This is not targeted for US based manufacturers. First two sentences of the article:

> Researchers at Chalmers University of Technology, Sweden, have developed a new method that can easily purify contaminated water using a cellulose-based material. This discovery could have implications for countries with poor water treatment technologies and combat the widespread problem of toxic dye discharge from the textile industry.
