ReCup - the sustainable coffee solution

ReCup replaces the paper cups with reusable cups

ReCup is a system managing the flow of the reusable cups from vendors to customers, from the customers to recycling, from recycling to cleaning and delivery back to vendors.

Used technology

Customer iOS ReCup app is written in Swift, the simulators of vendor and recycling hardware (QR-code scanner) are written in Java in Android Studio. The backend is based on Node.js, the data is stored in PostgreSQL database.

Challenges we ran into

Synthesis of different technologies and development of the process flow for the transactions were probably the most challenging tasks.

Accomplishments that we're proud of

Developing the process flow, cryptography, putting 2 apps and a backend together and finding a solution for the challenge.

What we learned

We learned how to teamwork. In a short time we had to build a team, come up with the plan, distribute the work and deliver the result.

What's next for ReCup

I think it's up to SBB, that was sponsoring the challenge. We don't think this solution could ever be profitable. But with the public support is could become a zero sum sustainable practice, helping the world to become better.
