The plastic waste in the world's oceans shall be reduced with the help of a multi-purpose dry cargo ship, which will be equipped with a pyrolysis factory that converts the plastic waste into oil. The freighter can remain in the garbage eddies for up to 5 years. The oil is transported to the next port by another ship. This can process about 15,000 tons of floating plastic waste annually. Advantages: Securing the food supply for about 50% of the world's population. Reduction of plastic in the food chain, which has already reached humans. 20 tons of CO2 reduction by processing 1 ton of plastic waste. Greater survival opportunities for marine life.
