Solution
Our solution was to use blockchain to transfer a virtual Costa cup to the user when they purchased a coffee, then when they throw the cup in the correct recycling bin, they can scan the bin (removing the blockchain Costa cup and validating that they did throw their cup away) and recieve points and rewards in return.
For the presentation, I designed a specific Costa Coffee recycle challenge app that would be use for a pilot, however, the launch version would be included in the Costa app.
In 2 days, I was a strong presence in the user research and product ideation, then I used any Costa branding material I could find to create an onbrand mockup of the pilot app, complete with a full flow and video explainer. Before then working on the presentation used to pitch our solution in the final presentation.
