The system consists of a newly designed cup for multiple use and a deposit system. The cup can be cleaned in stores or at your home and returned at multiple locations (McDonald and Starbucks stores) after use. The material of the cup allows recycling after return.
When buying the cup (usually with a drink) a deposit is charged. The return can be done in the store or at deposit machine (similar to the German plastic bottle deposit system). This system can, but does not have to be supported by legal regulations (i.e. stores which offer the cup have to feature a collection system). The cup features an incision, in which a sturdy drinking straw is attached; the straw can also be used for stirring. A lid can be pressed either onto the top opening or the base depending on use. For hot drinks, the cup features a small foldable handle, which can fold flush to the cup for stacking. A refund is paid upon return of the complete cup (with lid and straw).
We suggest the use of a mono material that is suitable for cold and hot drinks, and which meets the requirements of food law (for example polypropylene). The cup is firm, and not too light and can withstand a dishwashers’ cleaning cycle/water temperature.
Multi-use cups have a very clear ecological advantage over single use, disposable cups made of biological and degradable material. A deposit system (similar deposit technology for plastic bottles is already available) promises a high return rate based on refunding. A consumer adaptation and learning curve is to be expected - we suggest a preliminary project to investigate options for the deposit system and the level of payback).
It is conceivable to allow varying refunds based on different cups (color coding), brand logos or QR codes can be imprinted.
