A) Major Application of LDPE / HDPE Geomembrane. LDPE/HDPE film and sheet are U.V stabilized, black in colour. Impermeable flexible liner and are resistant to ground water source from being contaminated by the toxic leachate produced by water percolation through solid waste. Liquid waste, impoundment cut off walls, Gypsum stack, fly ash, and Municipal waste and spill containment system etc. The other Environment engineering applications are as under: 1) Effluent Treatment Plant, Land fill site & Solid Waste containment. 2) Reservoir, Canal and Pond Lining. 3) Sludge storage pit & Leaching Pads. 4) U.V Stabilized Films for green houses, Mulching and Mushroom Cultivation 5) Dungarees for Fertilizers, Sugar, Tea / Coffee and other food grains.,
