Bio-economy, Green Economy and the Circular Economy – same same?

It’s confusing, isn’t it? They are mostly political terms, so the exact definitions are probably non-existent, but let’s settle for vague. I do think they’re different and important to distinguish, so here’s my stab at explaining what the differences are between bio-, green and the circular economy, and then I throw in water sensitive design as a bonus. Oh, and distributed. That’s what all of these have in common. This is just my opinion, of course.

(The stress to submit the thesis has caused insomnia and to get myself to fall asleep I have been watching, wait for it, nail art videos.) So I went buying nail art stuff. Yup. Glitterified.)

[another UCT researcher said “imagine if 1/2 a million people had 2000 litre rain tanks, that would be 1000 million litres of water buffered. ]
