Outline of Research at the Start

ベトナムでは家畜ふんの堆肥化に嫌気発酵が用いられており,日本の好気性堆肥と性質が全く異なる.これには窒素成分の確保等の在来知が働いたと思われるが,残留病原菌,作物生育,環境負荷等に関する研究はみあたらない.現地では家畜飼養頭数が増大するとともに,廃棄物系バイオマスが多量に発生しており,堆肥化方式を現在の視点で見直す必要がある.本研究の目的は,嫌気性堆肥と好気性堆肥の機能性および環境負荷を比較することで,嫌気性堆肥の利点と欠点を明らかにし,両堆肥の特性を活かしたバイオマス活用堆肥を提案することである.日越研究者が,在来知を最新技術で多面的に評価し,堆肥の高付加価値化を目指す.

Outline of Final Research Achievements

In Vietnam, anaerobic fermentation is used to compost livestock waste, and its properties are entirely different from those of aerobic compost in Japan. Because livestock waste is locally increasing yearly, we need to rethink composting methods from a modern perspective. This study aimed to compare the functionality and environmental loadings between anaerobic and aerobic compost, clarify the advantages and disadvantages of local anaerobic compost, and propose the best composting way to increase soil ecosystem services in Vietnam. Through field surveys and on-site composting experiments, we found that Vietnamese compost is not produced under completely anaerobic conditions. Anaerobic compost showed high CH4 emissions during the composting processes. In the final anaerobic compost products, E. coli and salmonella were not detected, and their chemical properties were not essentially different from aerobic one.

Academic Significance and Societal Importance of the Research Achievements

我が国では家畜ふんを好気条件で堆肥化することに疑念を持たず,肥効評価法とともにその技術体系が作られてきた.一方,嫌気性堆肥は今もベトナムで一般的である.現地特有の慣習や気象条件のもとで作成されており,その作成方法や経緯は現地農家しか知り得ない.嫌気性堆肥の成立条件や機能性,さらには環境負荷に関する多面的な知見が得られれば,堆肥化および炭素・窒素循環に関する研究に新展開が期待できる.日本およびベトナムの若手・中堅研究者が直接顔を合わせた議論を重ねることによって,未来に繋がる信頼関係を築くことができる.
