Plastics are derived from oil, so it shouldn’t be too surprising that they can be converted back into oil. I guess the real question is why hasn’t this been implemented on a broader scale?
I like this, I think we should look into it more, it’s a good step in the right direction toward protecting our environment from dangerous drilling and pollution. However, I am still hoping to see our society switch more completely to alernatives that don’t involve oil and non-renewable resources.
