Landfills for household waste are one of the most important means of treating household waste in China.Geomembranes(GMs)are widely used in the liners and covers of landfills.A new GM,ethylene-vinyl alcohol copolymer(EVOH)GM was introduced in the proposed study.According to the existing researches,the EVOH GMs show the greater diffusive resistance to BTEX,methane and hydrogen sulfide than the traditional PE GMs.Using EVOH GM in a composite liner of a landfill can reduce the concentration of pollu-tants at the bottom of the liner.Incorporating an EVOH GM in a cover of a landfill should reduce methane emissions and odor impact significantly relative to a cover with a conventional GM.EOVH GMs can play an optimal role on the liners and covers of landfills.
