Sad statistics released by the World Wildlife Fund show that hundreds of thousands of marine animals become entangled and killed in fishing nets every year. Often these are abandoned nets, forgotten or lost by fishermen.
The future engineer, Spaniard Alejandro Plasencia decided to put an end to this. His Remora system incorporates secure RFID tags based on RFID technology combined with a dedicated smartphone app. This system helps fishermen to find lost nets, which are also called "ghost nets".
So that the network does not get lost, plastic markers of yellow or orange color with built-in RFID chips are attached to it. Reacting to search signals, they find themselves, and their location is displayed on the smartphone display. This information becomes known to the owners of networks or representatives of international environmental organizations.
Another know-how proposed by Alejandro is the addition of the d2w component to the plastic from which the nets are made. Thanks to him, the nets become biodegradable after prolonged exposure to sea water. By the way, the production of such a network requires almost 55% less energy than the production of current models.
