Plastic in rivers and seas is one of the biggest problems of our time. Whether bottles or bags, whether macro or micro plastic – the flora and fauna is impaired and destroyed. Six projects against plastic waste have already been presented here. The focus was on the seas. One of the initiatives is now also active in the rivers. This is very important because what is fished out in the rivers no longer ends up in the oceans. The magazine Fast Company reported on 26 October 2019: “In the Cengkareng Drain, a river that runs through the megacity of Jakarta, Indonesia, tons of plastic trash flows to the ocean each year. But now a new solar-powered robot called the Interceptor is gobbling up the waste so that it can be recycled instead. The system was designed by the nonprofit The Ocean Cleanup, which spent the past four years secretly developing and testing the technology while it continued to work on its main project – a device that can capture plastic trash once it’s already in the ocean.” (Fast Company, 26 October 2019) This is good news. However, the most important thing is to avoid plastic waste. Otherwise, the destruction of the waters will continue unstoppably.
