技術選択と実施規模を考慮した下水汚泥リサイクルシステムのLCAとLCC Life Cycle Assessment and Life Cycle Cost of Sewage Sludge Recycling System Considering Technology Selection and Implementation Scale 张, 佳文 1243 Sludge Recycling Life cycle assessment Life cycle cost Policy analysis Technology Selection Implementation of scale Carbon Trading Mechanism 北九州市立大学 博士(工学) With the acceleration of economic development and urbanization in China, wastewater generation has sharply increased. The wastewater system begins to change from “emphasizing sewage, despising sludge” to “emphasizing both sewage and sludge”. This dissertation considered the following: (1) environmental and economic performances of sewage sludge recycling were evaluated by life cycle assessment and life cycle cost. (2) Through policy scenario analysis, the vital factor for sewage sludge recycling system was determined. (3) the scale effect of sewage sludge recycling with different technological selections on the environment and economy was analyzed. (4) economic impact of introducing a carbon trading mechanism into sludge recycling was evaluated. Finally, the environmental and economic evaluation system of sewage sludge recycling system was constructed considering the technology selection, the implementation of scale, and carbon neutrality. The evaluation system provided references for governments and industries and promoted the construction of “zero-waste” cities with the wastewater system. doctoral thesis 2022-09-26 VoR application/pdf 甲第201号 https://kitakyu.repo.nii.ac.jp/record/1043/files/(KKDE1201ZJ)甲第201号_チョウ　カブン.pdf https://kitakyu.repo.nii.ac.jp/records/1043 eng open access
