　View Summary

本研究では，福岡県北九州市をケーススタディの対象として，下水汚泥の燃料利用における乾燥熱源の違いを考慮した，静脈系インフラが連携したエネルギー回収システムのGHG削減効果を評価した．脱水汚泥を高温焼却・ごみと混焼・造粒乾燥，消化ガスをガス発電・造粒乾燥の乾燥熱源・都市ガス代替，ごみ焼却排熱を蒸気タービン発電・汚泥の乾燥熱源に分けた比較ケースを5つ設定した．分析の結果，現在の北九州市における処理を想定したcase2（脱水汚泥：造粒乾燥，消化ガス：造粒乾燥の乾燥熱源，ごみ焼却排熱：蒸気タービン発電）が最もGHG削減効果が高なった．基準のcase0（脱水汚泥：高温焼却，消化ガス：ガス発電，ごみ焼却排熱：蒸気タービン発電）と比較するとGHG排出量の39%が削減可能であり，近接する静脈系インフラや産業工場の連携を活かしたエネルギー回収の有効性が明らかとなった．

Effect of environmental infrastructure collaboration on GHG reduction by sludge fuel utilization corresponding to industrial society change in future

　View Summary

本研究では，将来社会変化を見据え，全国での下水処理施設と産業工場，ごみ焼却場との連携によるGHG削減効果およびその要因について分析した．まず，下水処理施設における未利用汚泥量や，産業工場・ガス化溶融炉を有するごみ焼却場での下水汚泥燃料の受入可能量，発電設備を有するごみ焼却場でのごみ混焼可能量を把握する．次に下水汚泥燃料化技術のGHG収支を把握し導入事例を参考に連携システムとして，1)下水処理場で固形燃料化し石炭代替として混焼，2)下水処理場からごみ焼却場に輸送し汚泥を排熱乾燥した後にごみと混焼（ごみ混焼発電）の2種類を大枠として設定しGHG削減効果を分析した．その結果，2020～2030年において未利用汚泥の70.5%がエネルギー活用可能であり，そのGHG削減効果は最大で937 [千t-CO2]と推計された．また，産業工場の将来動向の変化に伴う各業種のGHG削減効果への影響を明らかにした．
