Since 2021, a French company named Carbios has been running an operation that uses a bacterial enzyme to process about 250kg of PET plastic waste every day, breaking it down into its precursor molecules, which can then be made directly into new plastic. It’s not quite composting it back into the earth itself, but Carbios has achieved the holy grail of plastic recycling, bringing it much closer to an infinitely recyclable material like glass or aluminium.
That’s a significant step forward from when the last time I read up on the plastic eating bacteria. Granted, I’d prefer it if it was recycled into something other than more plastic… but I’ll still take it.
The article explains that they use the bacteria to basically break down the plastic into two solutions, which they ultimately recombine into plastic—seemingly out of lack of any other practical use for the results.
I’m not a scientist, I don’t know what could be a better use for the results of the bacteria doing their job. And seemingly, neither do the scientists, but it’s still a very young project in the grand scheme of things.
