Reply to 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
Thats good but why don’t they just regulate the textile industry so they don’t dump their toxic dyes in the drinking water?
And is 80% really that good?
