Eco Fuel for Bizjets in ZRH
 

Finnish company Neste has delivered Compost based Kerosine substitute to tank the biz jets from the WEF conference in Davos.
It doesn’t say how it was got there though.
It costs 3 times kerosin prices, so I doubt if too much will get dumped - but if it was, it would be good for the roses...

There's already been commercial flights with Neste SAF, at least United from LAX and KLM from AMS.
