Curonian Lagoon
On January 7, 2020 the member company Klaipėdos Kartonas has been found to have been dumping large amounts of industrial waste waters into the Curonian Lagoon via a secret pipe. This resulted in AB Grigeo stocks falling over 30% at Nasdaq Vilnius, prompting the closure of the sales. Other consequences include major retailers removing Grigeo products from their shelves and canceling further orders.
