The problem is toxic chemicals poisoning our rivers and farmlands—zero liquid discharge (ZLD) means no polluted water is discharged, it's all treated and reused. After the court order, compliance costs maybe 15-20 rupees extra per kilo. But this 'extra cost' is a lie we tell ourselves to avoid change, re. I have seen the Noyyal river flow black and the wilted crops of my own village—that is the real, unpayable cost.
