Outline of Final Research Achievements

This work investigated pyrolytic interactions between plastic and biomass pyrolyzates during co-pyrolysis of plastic/biomass mixtures to achieve effective recovery of chemical feedstock and fuels. We have revealed several pyrolytic interactions such as enhanced production of levoglucosan from cellulose and methoxyphenols from lignin at slow pyrolysis conditions and enhanced gasification of plastics at fast pyrolysis conditions. These findings will be beneficial to control or maximize product yield and quality from plastic and biomass mixed wastes in the future.

Academic Significance and Societal Importance of the Research Achievements

将来的な世界人口増加や発展途上国の経済発展に伴う資源供給不足に備え、天然資源への極度の依存を脱却し、自国資源を創出する技術開発が喫緊の課題となっている。大部分が単純焼却または埋立処分に留まっているプラスチック/木質バイオマス混合廃棄物を化石資源代替に転換する本研究の社会的意義は大きい。また、プラスチック－木質バイオマスの共熱分解において生じる相互作用を明確にすること、また、共熱分解におけるプラスチックや木質バイオマス間の相互作用を活用した熱分解反応の制御は未だ実現しておらず、本研究の独創的な点である。
