The attributes we define for our service are circular, educational, inclusive, and collaborative: 1. We want to see how those things run in a circle loop, where resources are continuously repurposed. 2. We want to make our service educational, encouraging people to engage in sustainability actions. 3. Greenhive is not only for students but for everybody, including surrounding residents and tourists. 4. We want to make it a collaborative hub where people have the opportunity to share knowledge and skills. The diagram shows how Greenhive works sustainably. It has two lines that make up the entire circle. The inner line is the way of recycling food waste and producing organic fertilizer. And the outer line is the activities that people can participate in. It could start with people entering the restaurant and having a cup of coffee. Visitors could watch the fertilizer-making process. Greenhouse provides space for planting and picking.
