Kate Rushton Sorry for my late response. We've been busy at keeping our company survives recently. We will try our best to response all the comments and definitely come back here more often from now on. :P Thanks!!
Hi Winnie, It's a good question! From our observations, vendor partners' opinions depend on how much they care about the environment and how much their customers care about the environment. Most of the vendor partner who cares the environment think it is a good service, the vendor is willing to partner with us to refine the rental system, and will actually pay for this service. However, many vendor partners are not so eco-minded, and they think it's troublesome, immature and cost too much (comparing to disposable containers). It is what we've observed. Any comments are welcome! Thanks!
Hi Fernanda, Yes! A good mechanism design that can encourage users to return the cups plays a key role in the rental system. We will update it detailing what we've tried to encourage users to return the cups and our takeaways. Thanks for your comment! :)
