    In the recently proposed integrated approach for designing the entire agro-industrial process, there has been a lack of consideration on interannual meteorological variability consequences on production for particular plant cultivars/varieties grown at a specific region. In this study, we discuss how this shortcoming influences the simulation of productivity and GHG emission using a case study on two sugarcane cultivars and their processing system producing raw sugar and bioethanol. We also explore if consideration of interannual weather variability is possible by widely available meteorological data. From the results, we confirmed that it was possible to construct a modified multiple linear regression model that reflect the interannual variability of meteorological conditions from commonly available data sets without any additional data collection requirement, and that the productivity and GHG emission results derived by the simulation with and without such enhancement may disagree in some cases.

  30. Identify energy consumption and CO2 emission benchmark for the assessment of chlorine recovery from PVC wastes

    In Japan, about 72% of chlorine contained in PVC wastes is discharged back to the environment. As a result, there is a large potential to recycle chorine from PVC wastes to reduce dependency in salt importation meanwhile it will avoid the formation of corrosive HCl and dioxin. Authors have developed a chlorine recovery (Cl-R) process for PVC wastes to suggest a sustainable chlorine cycle. High dechlorination yield and considerable chlorine recovery potential have been determined by previous works. In this study, the Energy consumption and CO2 emission balance of current PVC waste treatments were researched to shed light on the benchmark for the new process. Through modification based on the data of mixed plastic waste treatment, we conclude that the net energy balance is -14.5 MJ/ kg PVC waste and the net CO2 emission is -0.03 kg/ kg PVC waste. This result reveals that energy could be saved through PVC recycling but current PVC waste treatment doesn’t help too much in CO2 reduction. Therefore, the application of advanced PVC waste treatment may be more desirable. The energy consumption and corresponding CO2 emission of the potential cycle are excepted to lower than the current situation.

    前年度に引き続き、自動車スクラップリサイクル最適化モデルの開発に取り組んだ。前年度に得られた自動車スクラップ中の合金元素有効利用量最大化の目的関数に加え、鉄及び合金元素一次資源生産に伴う温室効果ガス排出量最小化、合金元素一次資源生産額及び輸入額最小化、の2種類の目的関数を適用し、自動車スクラップ最適リサイクルが温室効果ガス排出に与える影響、一次資源生産及び輸入に与える影響、及び目的関数の違いによるスクラップと二次鋼種の最適マッチングの変化について解析を行った。自動車リサイクル最適化により、国内における温室効果ガス発生量は銑鉄生産及び合金元素一次資源生産分野において約2％の削減が見込まれると共に、約100億円相当の合金元素輸入を控除することが可能であるという試算に至った。輸入減少によって得られた控除分の一部は自動車スクラップの価格に上乗せすることができると考えられ、スクラップ業者において自動車スクラップを積極的に解体選別するインセンティブを提示することが可能となった。 これまで培った金属フロー分析用産業連関表作成の経験を生かし、米国にて米国版金属フロー分析用産業連関表の作成を行い、鉄鋼関連部門1部門を19部門に、アルミ及び銅を除く非鉄金属部門1部門を9部門に、計28部門の部門細分化を行い、米国経済における金属フロー解析用産業連関表を作成した。結果として、鉄、アルミ、銅をはじめとする基盤金属及びマンガン、クロム、ニッケルといった合金金属8種、計11元素の同時フロー可視化に成功した。この結果は、日本米国両国の金属利用構造の比較や、これまでの日本を対象とした同モデルの応用を米国についても行うことに非常に有用であると考えられる。
