Today’s Solutions: November 29, 2021

The problem with traditional recycling is that you degrade the material each time you do it. That’s why a France-based startup called Carbios is taking an entirely new approach.

Using a bioreactor, the startup is taking pulverized PET plastic waste—the kind of plastic found in drink bottles and polyester clothing—and mixing it with water and enzymes, which are then heated up and churned. In a matter of hours, the enzymes decompose the plastic into the material’s basic building blocks, called monomers, which can then be separated, purified, and used to make new plastic that’s identical to virgin material. The technology is especially cool because it can bring new value to colored bottles, which can’t be recycled into transparent plastic because current methods can’t remove the dye.

By working with different types of waste, the company believes that it can help increase the volume of plastic that’s recycled. That’s critical for keeping plastic out of the environment, and it’s also key at a time when manufacturers—under pressure from consumers to do more about the growing plastic waste crisis—have new goals to ramp up their use of recycled packaging.

Needless to say, we’ll be keeping a special eye out for Carbios and its special recycling technology.
