Abstract
Due to the increase of wastes in recent years, problems associated with treatment of wastes are happening in Japan. This paper aims to clarify the procedures by undertaking case study of former landfill sites to treat land contamination and redevelopment in the U. K. It investigated eight cases by interviews to local governments and government organizations and site visits. It is found that landfill sites are generally treated by encapsulation to cover the whole site of filled with wastes, thus, public open space is frequently used as the land use after the treatment. And in some cases where need to be developed into other uses in relation to land use plan, it then requires to treat in the different methods.
