We used Carrotmob to encourage our network of thousands of people to come together in a collective way to support and reward takeaway food retailers who switched away from plastic to compostable packaging. 

Here's how it worked 1) You joined the mob by signing up. The bigger the mob, the more enticing the carrot.2) We dangled the carrot of the mob's collective business in front of Hobart food outlets, asking them to switch from plastic to compostable packaging. 3) You ate at the shops that made the switch and congratulated them on the changes they made.
