2024-05-27 00:00:00 Plastic Origins is a citizen data collection project developed by the NGO Surfrider Foundation Europe (www.surfrider.eu) which aims to map macro-waste pollution washed up along the banks of Europe's rivers. The results will allow to identify and alert the most affected territories, to propose solutions to local actors and to measure the evolution of the pollution in time. To take part in the project, all you have to do is travel along the river around you, either by walking from the riverbank or using a kayak or any other watercraft from the water. You can use your smartphone and the Plastic Origins app to report the litter you find on your way. You have two options: 1. Using the manual mode, signal the presence of waste, bulky items, or accumulation areas by clicking on the corresponding buttons. 2. In development, the automatic mode will aim to identify such waste directly from videos thanks to artificial intelligence.
