Outline of Research at the Start

地方の小規模施設を対象に生活排水および廃棄物(生ごみなど)の個別処理の仕組みを抜本的に見直し、「集約メタン発酵を核としたバイオガス回収・直接肥料利用などを組み合わせた地域内の資源・エネルギー循環システム」の実現を目指す。新たな微生物活用手法として、乳酸発酵による浄化槽汚泥と生ごみの回収一体化、および光合成微生物によるメタン発酵汚泥の肥料価値向上に取り組み、導入効果を評価する。

Outline of Final Research Achievements

Organic wastes such as septic sludge and kitchen garbage are biomass resources that can be utilized as energy and fertilizer sources. The combination of biogas recovery by co-digestion and direct utilization of methane fermentation sludge as fertilizer can promote the circulation of energy and nutrient resources within the region. As novel methods of utilizing microorganisms, simultaneous collection of septic sludge and kitchen garbage using lactic acid fermentation and the improvement of the fertilizer value of methane fermentation sludge using photosynthetic microorganisms are proposed. Field surveys and laboratory-scale experiments are conducted to clarify the basic characteristics of these microbial reactions.

Academic Significance and Societal Importance of the Research Achievements

生活排水汚泥からのエネルギー回収の促進に向けて、乳酸発酵条件を活用する浄化槽汚泥および模擬生ごみの貯蔵実験により、メタン発酵によるエネルギー回収効率が向上することが示された。メタン発酵汚泥の肥料利用の促進に向けて、光合成微生物をメタン発酵汚泥に含まれる栄養塩を用いて培養できることや有価物が生産されることが、微生物の増殖特性のモデル化や遺伝子解析を含めて示された。地域で発生する排水・廃棄物に含まれる資源・エネルギーの循環を促進する新たな技術が提示され、脱炭素社会の構築に向けた技術につながることが期待される。
