Former Landfill Site

I have this picture in front of a monument in commemorated with the visit of Japan Emperor to this site. This is a trees replanting site at the Kosaka Town. This is a brown field site, a former landfill. The landfill was used for depositing the ash from incinerator operated by the Dowa Waste Management Group of Companies, the largest waste company in Japan. After a year, the grass starts growing and trees are planted now. They have no plan for making this site for any purpose except as a green area although no methane gas was noticed to discharge. According to them, this is precautionary principle they applied. Perhaps, this is lesson learned for some of the former land fill sites in Malaysia. Instead of making the sites for human settlement and commercial use, the sites should be treated properly and with cautious or else the danger to people is unavoidable.
