Reply to comment by dream_the_endless 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

If it’s effective enough, it will be useful anywhere. The excerpt you quoted might just simply be a way of marketing it so people are interested. “This can help poor people” is an effective way to garner interest in your work.

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 would not be the whole treatment process. I don’t think any nation does it all in one step.
