Abstract

Anthropogenic waste products utilization for old landfi lls rehabilitation. The paper presents remedial problems of old large sanitary landfi lls, particularly of embankments type. One of the main problems on a such kind landfi lls is to secure slope stability. The stability reinforcement methods consist of retaining walls, berms (constructed with selected waste materials), geogrids and mattress constructed of scraped tires. Metallurgical slag backfi ll material can be used for fi lters protection of leachate drainage and for technological roads construction on the landfi ll. The applied slope reinforcements and assurance of the proper performance of the leachate drainage in the landfi ll are of the greatest importance for the landfi ll slope stability and further use of landfi ll areas. Above mentioned aspects are described on the example of large landfi ll, localized nearby Warsaw. Radiowo landfi ll was founded in 1962, and now is at the end of the period of its operating and therefore remedial works have been undertaken there. In the future Radiowo landfi ll area will be adopted for recreation and sports purposes (view points, skiing, cycle roads etc.).
