Marnie Hughes Warrington speaks up for a fundamental of civilisation, western, eastern everywhere, in the new essay in her series on the building of the new ANU.  The intellectual challenge she addresses is the history, theory, and practise of protecting the environment from fat, gunk in the waste pipes of commercial kitchens that fouls the environment if it escapes. She describes the basics of beating the fat bergs and how ANU has built a state-of-the art fat containing system, based on new technology in trapping grease and big thinking on waste logistics. Fascinating stuff, which makes CMM wonder, if the Enlightenment was that crash-hot how come 18th century waste disposal was so crap?
