    　View Summary

     In this research, we estimated the potential of demand and supply in sewage sludge fuelization system utilizing a cement production infrastructure in Hyogo coastal region between 2010 and 2040. We also estimated GHG emissions through the introduction of this system. From the analysis, we reached the following conclusions; 1) In all scenarios for economic growth of cement industry (high, low and medium growth scenario) based on the prediction in the previous research, the cement production infrastructure could accept carbonized sewage sludge from 5 sewage sludge treatment facilities at a co-firing ratio of 10% (carbonized sewage sludge/coal). 2) In high economic growth scenario, the co-firing ratio of 10% could make cement production infrastructure accept carbonized sewage sludge produced at 6 sewage sludge treatment facilities. 3) The sewage sludge carbonization system in collaboration with the cement production infrastructure could reduce GHG emissions by up to 125.4% between 2015 and 2040.

    　View Summary

    This study aims to clarify the effects of GHG reduction by utilizing various sewage sludge fuels based on collaboration among sewage, industrial, and environmental infrastructures. As a result, the followings are observed: a) a low mixed combustion ratio causes limited GHG reduction in pulp industry, and it is important to take balances of regional sludge fuel and industrial fuel demand into account corresponding to industries; b) GHG inventory are compared for various sludge fuel utilization technologies based on reference materials, and adjacent of sewage and garbage incineration plants to reduce GHG caused by transportation of dewatered sludge; c) collaboration of sewage, industry and environmental infractructures can reduce 679 thousand tons of carbon dioxide per year, which is given by 85% of un-utilized sewage sludge; d)increase of mixed combustion ratio in pulp industry give great GHG reduction effects.

    　View Summary

    In this research, the energy and material flows in the glasshouse horticulture of flowers and ornamental plants were identified based on the field and interview survey at a specific site located in Arida district of Wakayama Prefecture, Japan. In addition, a quantitative analysis was conducted to estimate the GHG emissions derived from each energy and material consumed in cultivation process, applying Life Cycle Assessment (LCA). Furthermore, we developed seven alternative options of heating equipment used in glasshouse horticulture and then evaluated GHG emissions reduction potential through introducing low-carbon equipments in substitution for conventional oil boiler and utilizing woody and waste biomass for fuel based on the result of LCA. From the analysis, we reached the following conclusions: (i) The GHG emissions from glasshouse horticulture account for 98% of the entire emissions and almost all of them is induced by heavy oil combustion in conventional boilers for heat generation. (ii) The installation of wood chip boilers into glasshouse horticulture plant and promotion of woody biomass utilization can reduce GHG emissions by 64%, compared with conventional oil combustion. (iii) As an electric heat pump produces heat greater than the electricity consumed, 59% of GHG emissions can be reduced through replacing conventional oil boiler by it. (iv) The monetary value of carbon credits gained by installing wood chip boilers into glasshouse horticulture plant is estimated at about 36 thousand yen per year if the domestic market price of credits is 1.5 thousand yen per ton CO<sub>2</sub>.

  • Development of Co-benefit Model of Biomass Production and GHG Emissions in Greenhouse Horticulture Plant

    　View Summary

    Agricultural ecosystems can provide high quality biomass production as an ecosystem service. On the other hand, intrusive agriculture and searching for higher profitability, has induced enormous Green House Gas (GHG) emissions from agricultural ecosystems. In this way, trade-off between mitigating climate change and benefiting from biomass production ecosystem service has occurred. This trade-off is especially evident in greenhouse horticulture because of the requirement of high quality biomass production. Against this background the goal of this study is to develop a co-benefit approach between reducing GHG emissions and sustaining biomass production in greenhouse horticulture as a flagship model of solving this trade-off structure. Biomass production and GHGs emission from soil were analyzed using DNDC (DeNitrification DeComposition) model. Fuel consumption for heating was analyzed using a tool for estimating greenhouse heating fuel consumption. GHGs emission reduction by means of greenhouse temperature management and fertilizer use reduction was analyzed. As a result, the case study plant was found to be using excess fertilizer. Reducing fertilizer use by 45 % was found to have limited effect on the biomass production. Environmental efficiency defined as the ratio of biomass production and GHGs emission was found to be at its highest when fertilizer use was reduced by 47% and the greenhouse temperature was lowered by 3 at the case study production plant.

    　View Summary

    本研究では，人口減少社会における地方都市の汚泥処理で重要となる将来の施設整備計画として，施設の統廃合や燃料転換技術の導入，清掃工場でのごみ・汚泥混焼技術の導入に関するシナリオを構築した．和歌山市を対象とし，汚泥処理の集約化や現有焼却炉代替の高温焼却および燃料転換技術の導入に加え，清掃工場でのごみ・汚泥の混合処理による環境負荷量の削減効果をシナリオ別に評価した．その結果，GHG排出抑制を図るとき集約化に加え燃料転換技術の導入が有効であり，将来も下水道整備が進展する地方都市においては中長期の視点に立った整備計画の立案が重要であることが示された．将来の下水汚泥・ごみ発生量は，下水道整備計画の変更．社会情勢の変化，廃棄物処理政策の見直しなどにより変化するものの，清掃工場への汚泥焼却の移管シナリオは，燃料転換技術の導入が困難な状況の場合，検討する価値があることが確認された．
