In the summer of 2019, Coca‑Cola Hungary committed to clean Tisza, the second longest river in Hungary, partnering with the water management directorate and an NGO. The Zero Waste Tisza program, supported by The Coca‑Cola Foundation with HUF 73 million, focuses on removing plastic pollution from the river and accumulated garbage from the floodplain; these goals are also supported by volunteer actions of Coca‑Cola Hungary.
Together with the PET Cup, the main objective of the two-year-long Zero Waste Tisza program is to collect and recycle at least 80 tons of waste. So far, the company has collected more than 49 tons of waste with the PET Cup.
