Outline of Final Research Achievements

Observations at several landfill insides were conducted in order to evaluate of waste stabilization looking forward future waste quality change. Our results revealed that the mixing ratio of incineration ash and incombustible residue affected the concentration of methane and hydrogen gaseous generated from waste. And we concluded that these landfill sites were in the phase of steady-state methane formation one to two years after lanfilling operation by the temporal change data of inner temperature and methane concentration. In addition, we evaluated not only the influence on waste stabilization of overhead flooding at landfill, but also the delay of waste stabilization by landfilling chemical treated incineration fly ash.
