Greetings @Madridbg "The fundamental idea behind the project is based on two differentiated aspects, firstly the reduction of polluting material coming from hydrocarbons or fossil fuels and the second aspect points to the sustainable use of waste, so that they are no longer seen as pollutants and we can include them in a new production system." Excellent publication, starting to use waste from the sea to generate plastics is very good for the environment. Hopefully something can also be done with the spines to not lose any of the fish.
