Since its establishment in 1994 in Thoothukudi, Tamil Nadu, Sterlite Copper was mired in several controversies, including flagrant violation of compliance norms, causing extensive environmental degradation and health hazards. Sterlite Copper faced stiff opposition from the local community when it announced expansion of its production capacity in 2018.
