It seems to be an article like many thousands that are published each year; a scientific and technological article of the sort that scientists have got to publish for their careers. And yet, this article by Jean-Paul Lange (a Belgian engineer who works with Shell in Amsterdam) will probably change the world more profoundly than
Why PEF is better than PET

Biobased PEF (polyethylene furanoate), the new feedstock for soft drink bottles (Coca Cola and Danone) is not only green, but also cheaper to produce than both fossil and drop-in green PET (polyethylene terephthalate). It also has better properties. Tom van Aken, Avantium’s CEO, explains it again and again. PEF is six times a better barrier
