Geosynthetics are nowadays of common use in landfills. Two European organisations are now working on this topic : the CEN Technical Committee TC 189 for the standardization level, and the ESSMFE Technical Committee 8 for the Technical Recommendations about Geotechnics of Landfill Design and Remedial Work. The ETC 8 is working on a broader geotechnical approach of landfill geotechnics, but, to cope with geosynthetics it has agreed to take into account the general approach of the EN TC 189.
