πthe plastic does not disappear just because you melt it using a microwave. Or have I understood something wrong?
yes, you missed the important bit. the plastic is carbonized, skipping the processes/stages that would create intermediary, poisonous chemicals.
And what do you do with this carbonized plastic? Or is it a way to get CO2 out of the air? Or is the example above hust not feasible because it is hard to automate?
ha, you really need to ask about what to do with pure carbon?
these are just scientists attempting to find a way to extract precious metals without destroying the environment. dont chase the perfect ignoring the good research.
Wish they had chosen a better title for the article..
