| Research Abstract |
An implementation of low-cost system toremove Dioxins in soil, which is a consequence of Vietnam war in 1960s-1970s is highly desired in Danang for its safe urban development. In this regard, a development of improved methane fermentation process receiving organic wastes was highlighted toprovide heat energy for the thermal decomposition of dioxin-polluted soil. While developing the new process in lab-scale, the material flow of municipal solid wastes in Danang including food waste was clarified through field survey. It appeared that a large amount of the food waste was currently being beneficially transferred to piggery farms outside Danang, and accordingly non-feedable fraction (e.g. septic tank sludge) wasthought to be the essential organic source for the methane fermentation process, unlikeother developed countries. The field research also reveled apart from the hot-spots of Dioxins, the presence of the compounds in Danang river was limited and most of micropollutants were mainly attributed to insecticides from farms in the area.
