探索坦尚尼亞手機回收的經濟潛力：循環經濟方法
Exploring the Economic Potential of Mobile Phone Recycling in Tanzania: A Circular Economy Approach
摘要
Chinese Abstract. 近年來，全球電子廢棄物（e-waste）的產生量大幅增加，此趨勢也延伸到非洲地區，包括坦尚尼亞。儘管電子廢棄物中含有有害物質，它有含有大量有價值的資源。因此，妥善且精確的回收與處理電子廢棄物，具有減少環境污染並帶來經濟效益的潛力。 然而，與許多其他發展中國家一樣，坦尚尼亞由於缺乏熟練人員、技術和基礎設施，在電子廢棄物管理方面面臨挑戰。坦尚尼亞目前依賴非正規部門，其收集、運輸、儲存和拆解能力有限，這通常導致電子廢棄物出口到其他國家進行回收。本研究旨在評估坦尚尼亞手機回收的經濟潛力，這是對該國電子廢棄物回收經濟的首次全面分析。 坦尚尼亞電子廢棄物背景下的數據收集和分析方法依賴於通過諮詢主要利益相關者（包括國家環境管理委員會電子廢棄物管理人員）收集的信息。 分析結果表明，整合有效的管理措施和技術干預措施有助於促進坦尚尼亞的電子廢棄物回收經濟。此外，本研究還估算了坦尚尼亞電子廢棄物回收經濟的規模和分佈。此外，本研究還制定了針對坦尚尼亞電子廢棄物回收經濟的成果評估指標，作為該領域發展和持續改進的參考和指導原則。 本研究不僅有助於潛在投資者了解電子廢棄物（尤其是報廢手機）的回收經濟潛力，而且也有利於政府作為決策過程中的利益相關者。總體目標是促進電子廢棄物管理的循環經濟方法，同時解決環境問題並促進該地區的經濟增長。 關鍵詞：電子廢棄物、電子廢棄物管理、經濟潛力、電子廢棄物回收

English Abstract. Recently, the global generation of electronic waste (e-waste) has significantly increased, extending to regions such as Africa, including Tanzania. Despite containing hazardous substances, E-waste is a repository of valuable resources in significant quantities. As such, proper and precise recycling and treatment of e-waste harbor the potential to mitigate environmental pollution while concurrently conferring economic benefits. However, like many other developing countries, Tanzania needs more skilled personnel, technology, and infrastructure to handle e-waste management challenges. Tanzania currently relies on informal sectors with limited capacities for collection, transportation, storage, and dismantling, often resulting in the export of e-waste to other countries for recycling. This study evaluates the economic potential of mobile phone recycling in Tanzania, representing the first comprehensive analysis of the country's e-waste recycling economy. The data collection and analysis methodology in Tanzania's e-waste context relies on information gathered through consultations with key stakeholders, including the National Environmental Management Council E-waste manager personnel. The results of the analysis show that integrating effective management measures and technological interventions facilitates and promotes the e-waste recycling economy in Tanzania. Additionally, this study estimated the scale and distribution of Tanzania's e-waste recycling economy. Furthermore, the study formulated outcome evaluation indicators tailored to Tanzania's e-waste recycling economy, serving as references and guiding principles for advancement and continuous improvement. This research not only aids potential investors in comprehending the economic potential of recycling e-waste, especially End-of-Life mobile phones, but also benefits the government as a stakeholder in decision-making processes. The overall goal is to foster a circular economy approach to e-waste management, simultaneously addressing environmental concerns and promoting economic growth in the region. Keywords: E-waste, E-waste management, Economic potential, E-waste recycling.
