Or, I'm proud of my country right now. Okay, the one I currently live in.
Three New Zealand entrepreneurs have invented
a commercially viable way to recycle old car tires.
The process they've invented breaks the rubber in old tires to release gas, which is cooled and can be made into various useful compounds such as carbon and oil. Which is a great way to solve an environmental problem - the piling up of old tires - and make money at the same time.
As I always say: Three cheers for optimistic, market integrated environmentalism!
