Agricultural waste is inedible parts or by-products during agricultural production or processing. These wastes cause environmental impact and are a headache for local governments. This study mainly focuses on grapevine agricultural waste to see whether grapevine waste can be converted into useful commodities through the integration of local resources to achieve the goal of the circular economy. This study uses on-site visits, participatory design, and industrial design methods to reuse and design grapevine agricultural waste that originally seemed useless. Combined with local resources, we integrate communities, returning youth, temples, manufacturers, etc., to develop a series of daily necessities. Agricultural waste has once again become an indispensable product in life. As a result of the research, a series of biochar products, tableware, religious items, etc., have been developed and won many awards. Develop a feasible production model for the circular economy and serve as a model for sustainable product design.
