The PLASTIC CUP is a Hungarian civil initiative was launched by Természetfilm.hu Association film making society for the cleaning of the Tisza river. With the aim to call the attention to the growing problem of plastic pollution of our water resources, the Cup itself is  a real 10-days environmental action towards cleaning the floodplain area of the river. The initiative known as the "Water Clean-up" is organized by Természetfilm.hu Association, the Hungarian Association of Environmental Enterprises (HAEE) and the Sonar Diver Team. 

In 2018 – altogether for the sixth occasion – the waste picking race took place between 4 –12 August 2018 on a 70 km long section of the river from Szatmárcseke to Tiszamogyorós. It was combined with a pre-race started in Transcarpathia (Ukraine) few days before the Cup.

The race started with the construction of the boats that already demonstrate the plastic problem: the 21 plastic boats used around 30.000 collected, waste plastic bottles and other re-used fixtures as main building blocks. Moreover, the unique JOINTISZA boat reduced the use of wood, main construction material for the board of other boats and used wasted plastic pallets destined for shredding and recycling. This led to significant reduction of weight that in combination with using truck tilt to cover the hull of plastic bottles providing buoyancy secured ultimate speed and manoeuvring features to the boat. The international crew lived with this asset and won the speed track of the Cup.  Another criterion of watercraft design is the sole usage of renewable energy as propulsion which can include solar energy, sails and of course, human power via paddles and tricky pedal propulsion systems. All in all, 21 boats, accompanied with around 40-50 canoes, started the race on the 6th August 2018 at Szatmárcseke, with near 350 competitors and volunteers on board.
