Interesting strategy that you have implemented with your students and it catches my attention. I have always had in mind a project to create a Blockchain-based system that involves communities in waste management and the generation of profits in cryptocurrencies. This would involve the creation of a whole business conglomerate, focused on recycling, for the management of household waste or partnering with a company that already does it and is willing to get involved with the Blockchain.
The idea would be to grant rewards in cryptocurrencies for the correct management of household waste, handing it over to a company that would be in charge of processing it. A system of payments would be established for each item of waste generated, processed and delivered for recycling and, I think that by basing it on our blockchain, the token earned could be exchanged through HiveEngine. This would require, in addition to creating or partnering with a recycling company, the design and implementation of a community or tribe with its utility token. In addition, it would also be interesting to add the possibility of earning HIVE and the token for creating content related to this topic.
I think it is a great idea and would provide a great contribution to the community both in the part of financial education, finance and Blockchain as well as give a very interesting solution to a common problem in any community. It would be interesting to see how your students could approach it and of course, I would welcome some feedback if the idea comes to fruition. Best regards.
