Reply to comment by redratus in Scientists have shown how toxic dyes can be filtered out of wastewater using the method and material developed by the group.

They don't dump toxic dye into drinking water. That's already very illegal.
In the USA, these industries are regulated by their local wastewater authority. They will have some pretreatment policy regarding these dyes.
This article is detailing a breakthrough treatment technology. Once this becomes industry standard it will likely be written into those pretreatment policies.

Reply to My first potato peeler (Sparschäler) I got this Sparschäler 10 years ago already used by my grand mother. It is still a mass product and you can buy it for round about 5 USD. But this one is made in West Germany so at least 33 years old and almost daily in use. by Secundus_Scipio
I had a Fackelmann sparschäler I acquired in CZ, and it was one of the only things I brought back home to the US with me. Lost it in my divorce. Someday I will return to Europe and replace it.
