"Slow" packaging for fast food ?

What does it mean?
This is the idea of using and reusing containers, plate, cup , etc. for quick service restaurants (QSR) for instore consumption or on the go eventually. If the food service is fast, the collection/cleaning/ deposit /reuse container services need to be quick too. Having the right & convenient system in place will be crucial for customers and will make teh diffrence , don't you think ? So, no Slow packaging but Fast packaging or sytem need to be implemented !
