Starbucks didn’t exactly get where they were by accident. I recently saw this sign in a branch on Gloucester Road (it says ‘Coffee Grounds for Your Garden’). Starbucks are giving away some of their waste coffee grounds for free. The cost of packaging is probably almost equal to the cost of disposal saved, plus it benefits their green credentials. It’s also another good reason to go to Starbucks rather than another coffee shop down the road.
This looks like a pretty clever marketing detail.
