Geosynthetic Lining System for Modern Waste Facilities – Experiences in Developing Asia

Abstract

he applications of geosynthetic liner systems are being used with increasing frequency, particularly for the environmental engineering applications in developing countries at recent years. Polyethylene geomembrane sheets have been widely accepted as a standard component of geosynthetic lining system in the waste containments for decades, which includes solid waste sanitary landfill and wastewater treatment lagoons. The paper presents the application of impervious Polyethylene geomembrane used as bottom liners and final capping systems in waste containment facilities in developing Asia. This paper discusses the characteristics and durability of polyethylene geomembrane as a lining solution to the waste containments. Successful case histories on the application of polyethylene geomembranes in bottom liner and final capping systems of modern solid waste facilities are illustrated.
