Oekotech or Ecotech segment refers to use of technical textiles in Environmental Engineering. The primary segment in this is Landfill waste management which refers to the use of Geosynthetic products to secure landfills against leakage of municipal or hazardous waste. Other areas include secondary protection in Chemical/Oil Industries (ground covers and the like around process tanks for secondary containment should the tanks leak). A modern engineering landfill has the following components - a basal lining system to prevent the contamination of soil, and ground water by pollutants, a capping system to seal the waste when the capacity of the landfill is exhausted, an impervious sealing layer which prevents the entry of pollutants in the ground, a leachate collection system for the collection and transmission of leachates to a collection pit, a secondary leachate collection/leak detection system.
