There is one clear solution to this problem: having students take their container to the cashier to get a token, and then dropping their container on the conveyor belt to be rinsed and washed by dining hall staff. There is one main problem with this solution. The program is still limited to a certain number of people, and under this system we cannot be sure that non enrolled students will not use other members' "returned" containers to get a token for themselves. As soon as the program is open to the whole campus, this new system will be an easy fix to eliminate the need to rinse containers before returning them.
As I am drafting the surveys, I am asking questions about problems that people have and possible solutions they have come up with to solve these issues. I expect to analyse the surveys in 2 weeks.
