Since only 10% of plastic is actually recycled right now, many are trying to find a way to raise that trivial number. Now a French company has developed an enzyme that can break down plastic into usable form. This new process should be economically sustainable...
"How much would using recycled PET cost compared to starting with
petrochemical feedstocks? The authors estimate that, if the protein can
be made for about $25 a kilogram, then the cost of the process will end
up being about 4 percent of what you can get with for the PET made from
it. While that might not be as cheap as petrochemicals—especially now,
after oil prices have collapsed—it's going to be relatively immune to
future price shocks and is far more sustainable."
We can hope!
