Make More Things Out of Recycled Plastics

Over at Vice, one author asked a simple question: why don’t we make everything out of relayed plastic? The short answer is that oil is too cheap and companies don’t see benefits of recylcing plastics on their bottom line. Instead of championing for higher consumption taxes or waiting for oil to go up again some people are changing the technology behind recycling plastics. By making the process of recycling cheaper, consistent, and more efficient we can make recycling plastics a default decision for many companies (and leave that oil in the ground).

Garcia said researchers are now looking for new and more efficient ways to make, and break down, plastics. “Since we make plastics chemically, the way we treat them at end of life is also probably going to be chemical,” she said.

Garcia cited a number of examples, such as chemical recycling, where the plastic is exposed to a catalyst at a very high temperature, causing the underlying compounds to break down. It’s how scientists have been able to make fuel out of old water bottles. Garcia said this technique still requires a lot of energy, and is very expensive, but she believes scientists will eventually figure out how to use a similar process at a much lower temperature.
