垃圾焚化廠轉型生質能源中心可行性評估規劃專案（第2年）
| 中文摘要 | 本計畫主要延續上年度計畫「垃圾焚化廠轉型生質能源中心」之先期規劃，接續辦理其政策評估說明作業；並有鑒於目前推動及參與垃圾掩埋場挖除再生活化之急迫性，納入「垃圾掩埋場挖除再生活化」之先期規劃及政策評估說明等作業，作為當前推動垃圾處理政策之依據。在垃圾焚化廠轉型生質能源中心政策評估方面，垃圾焚化廠轉型為結合機械熱處理 (MHT)與焙燒 (Torrefaction)技術產製「生質煤炭」之生質廢棄物再生能源中心，「生質煤炭」直接供應國內燃煤電廠或汽電共生廠替代天然煤炭使用；經由相關環境項目之質化及量化評估後，在整體及個別評估項目均顯示，推動生質能源中心較焚化處理現況更減少環境污染負荷(如戴奧辛排放量降低)，且落實生質化、發揮能源化(每年取代天然煤炭量約641,353.55公噸，產生1,708,431,460 kWH電量)、資源化及減碳效益(如總排碳量為-85,958,402 kgCO2e，屬負排放)。在垃圾掩埋場挖除再生活化政策評估方面，經選定之垃圾掩埋場，於挖除掩埋物並進行分選後，將可燃廢棄物焚化處理，其餘資源物、腐質土、土石等均可回收再利用外，再生活化並可恢復掩埋容積，以提供目前資源循環零廢棄下尚需掩埋或暫存之空間，避免新闢掩埋場之壓力及阻力；經由相關環境項目之質化及量化評估後，結果顯示雖然在掩埋場挖除作業期間，因土地產生擾動對環境產生影響，但因屬於短期及臨時性，透過相關預防減輕及防治措施，可降低對環境之影響，且挖除活化之環境效益，可移除潛在污染源、資源回收、增加掩埋容積及避免新闢掩埋場壓力等環境效益，因此整體政策上對環境影響較維持現狀(不挖除但不足時需新闢掩埋場)為低。 | ||

The Evaluation on the Feasibilities of the Transformations of Refuse Incinerators to Bio-energy Cent
| 英文摘要 | The objective of this project was to conduct strategic environmental assessment (SEA) on two waste treatment policies – “Transformations of Refuse Incinerators to Bio-energy Centers” and “Landfill Mining and Reclamation.” Planning the conducting method of landfill mining and reclamation was also carried out with the intention of reforming Taiwan’s waste strategy. For the “Transformations of Refuse Incinerators to Bio-energy Centers”, the bio-coal produced from the Bio-energy Centers could serve as coal in power plants, which could reduce the usage of fossil fuel. The results of SEA showed that the Bio-energy Centers produce less pollution than incinerators (e.g. reduce dioxin emission), produce energy (produce 1,708,431,460 kWH of electricity and reduce the usage of coal for 641,353.55 tons per year), and the recycle rate of the waste could be enhanced after Mechanical Heat Treatment. Furthermore, because the bio-coal is carbon-neutral, it could provide more usable energy and greater greenhouse gas reduction (the total CO2 emission is estimated to be -85,958,402 kgCO2, which is negative). For the “Landfill Mining and Reclamation”, mining landfill sites could retrieve recyclable materials to generate revenue and reclaim capacity for future burial. The SEA results revealed that though the environmental impact during the mining process would be significant, by taking prevention actions, the impacts could be reduced. Landfill mining could be used to achieve a range of objectives such as remediate the potential contaminants, retrieve recyclable materials, increase the existing landfill capacity and eliminate the difficult process of siting a new landfill. As a result, landfill mining and reclamation offers more advantages than keeping the original landfills, which made this policy practical. | ||
