Recycling
The concept of recylcing petroplastic is economically inviable. However, it is an extremely effective as a greenwashing tool for Fossil Fuel Industry Disinformation. In fact, so-called "recycling" is mostly carried out in the global south under conditions that are, to say the least, concerning:
Up until 2017, most of the plastic waste collected in Europe and in the United States was shipped to China, as was most of the mixed paper. Then Beijing imposed a new policy, known as National Sword, that prohibited imports of yang laji, or “foreign garbage.” The move left waste haulers from California to Catalonia with millions of mildewy containers they couldn’t get rid of. “plastics pile up as china refuses to take the west’s recycling,” a January, 2018, headline in the Times read. “It’s tough times,” Simon Ellin, the chief executive of Britain’s Recycling Association, told the paper.
Trash, though, finds a way. Not long after China stopped taking in foreign garbage, waste entrepreneurs in other nations—Malaysia, Indonesia, Vietnam, Sri Lanka—started to accept it. Mom-and-pop plastic-recycling businesses sprang up in places where they were regulated laxly, if at all. [At] one such informal recycling plant, in New Delhi ... [a journalist] found workers in a fiendishly hot room feeding junk into a shredder. Workers in another, equally hot room fed the shreds into an extruder, which pumped out little gray pellets known as nurdles. The ventilation system consisted of an open window.
Nurdles, which are key to manufacturing plastic products, are small enough to qualify as microplastics. (It’s been estimated that ten trillion nurdles a year leak into the oceans, most from shipping containers that tip overboard.) Usually, nurdles are composed of “virgin” polymers, but, as the New Delhi plant demonstrates, it is also possible to produce them from used plastic. The problem with the process, and with plastic recycling more generally, is that a polymer degrades each time it’s heated. Thus, even under ideal circumstances, plastic can be reused only a couple of times, and in the waste-management business very little is ideal. [1]
