Five years they are working on. The French company Carbios has developed a chemical process that allows endless recycling of plastic bottles. Scientists have created an enzyme that sticks old plastic tissue together. This molecular technique makes it possible to manufacture plastic in new condition using recycled plastic. The company hopes to industrialize on a larger scale by the end of 2020. As a reminder, 91% of plastic waste in the world is not recycled. Photo credit: Jonathan Chng
