Outline of Final Research Achievements	In this study, we first conducted a Himalayan oyster mushroom cultivation test using palm biomass (PB), and clarified that PB can be used as a medium material from the yield and quality of fruiting bodies. Next, a fermented TMR feed containing 10% of the PB waste bed was prepared, and an in vivo digestion test using goats was conducted. There was no significant difference from the TDN content in the control group (0% waste bed), and it was found that livestock could be fed. Finally, after preparing compost from the feces of goats fed the PB waste bed, a komatsuna cultivation test was conducted, and it was confirmed that there was no significant difference in growth from the control group. From the above results, we were able to construct an Up Cycle type industrial symbiosis system in which the palm industry, mushroom industry, and agriculture & livestock industry collaborated.

Academic Significance and Societal Importance of the Research Achievements	本研究ではDown Cycleが主であったパームバイオマスの利用を見直し、食用きのこの生理的特性を活用して、きのこ（低カリウム廃菌床）→低カリウム家畜飼料（排泄物）→作物（堆肥）へとUp Cycleを実現し、異種産業のコラボによる持続可能な環境低負荷型食料循環産業共生システムを構築した。加えて、本システムの生産物はハラル社会に適合していることを確認しており、限りある資源の有効活用に必要な研究を行う環境学分野と社会科学分野の融合を図ることができた。さらにUp Cycle型食料供給システムを日本発の独自の技術として東南アジア（マレーシア、インドネシア）に、研究協力機関を通じて発信できた。
