Marisa, thanks for sharing your thoughts about this. Your thought is another option to tackle this problem with an incentive. I think it is also very good. Why didn't online food delivering companies take this method? I think there is no much incentive for them, and they probably do not have a CSR concern in mind. In order to co-work with them, I proposed the charity idea, which will not reduce their profits, meanwhile give them the opportunity to do CSR. In the old model, if customers are charged for like 2 dollars for the disposable items, actually the cost for the items are way less, that being said, restaurants and take away companies make profits by selling disposable items. I also hope my solution will really tackle their concern, and make a change for this industry. Thanks again, Marisa, lets keep in touch to see how this evolves.
