牡蠣養殖是澎湖縣主要的漁業項目，每年平均為澎湖產生約2.7億的產值。但也因此 在當地產生每年約3,000噸的牡蠣殼，目前己堆積成約有60,000公噸的農業廢棄物。 由於牡蠣殼主要由碳酸鈣(CaCO3)所組成，為極具潛力的資源材料。但因澎湖地屬離 島，考量運送成本與碳足跡等問題，並不適合運送到臺灣處理。因此如何在當地資 源化，並發展應用方式，更為符合循環經濟的精神，並可達到減少碳排的目的。本 計劃為解決澎湖牡蠣殼廢棄物問題，並推廣應用方式。擬分析評估澎湖牡蠣殼的產 地，並規劃建立回收機制，依牡蠣殼生產樣態設計資源化產線，將牡蠣殼處理後 ，變成可以利用的資材，後續以社區經營模式。並導入應用技術，如鹼激發和 ３Ｄ列印等方法，做為水泥替代，社區產用應用，農業資材等用途。達到循環經濟 的目標，並達到解決現階段牡蠣殼廢棄物的問題。

Oyster aquaculture is a major fishery production in Penghu County, generating an average annual output of about $270 million for Penghu. However, it also generates about 3,000 tons of oyster shells per year, which have accumulated into about 60,000 metric tons of agricultural waste. Oyster shells are composed mainly of calcium carbonate (CaCO3), which is an extremely promising resource material. However, because Penghu is an outlying island, it is not suitable to be transported to Taiwan for processing due to transportation costs and carbon footprint issues. Therefore, it is important to develop a local resource and application method that is in line with the spirit of circular economy and can achieve the goal of reducing carbon emissions. This project aims to solve the problem of oyster shell waste in Penghu and to promote its application. We plan to analyze and evaluate the production sites of oyster shells in Penghu, and establish a recycling mechanism to design a resource production line based on the production pattern of oyster shells. The oyster shells will be processed and turned into usable materials for subsequent community operation. We will also introduce applied technologies, such as alkaline excitation and 3D printing, for cement replacement, community production applications, and agricultural materials. We aim to achieve the goal of circular economy and to solve the problem of oyster shell waste at this stage.
