I visited the Biospheric Foundation a couple of times during the 2013 Manchester International Festival. It was an interesting project, taking first steps towards a self contained urban farm.
Sadly, it has gone bust, with over £100,000 in debts and tales of bad behaviour and rotten business practices from people who worked with it.
It’s a terrible shame, and it’s likely to put people off funding similar projects, which just makes it worse.
