Final Capping System
In general, the landfills are capped with geotextile polyethylene liner, overlaid by synthetic geo-composite drainage layer and the soil to promote vegetation growth.
Leachate Management
A leachate management system including pumping wells is in place for a restored landfill. Collected leachate is being treated on site leachate treatment plant prior to disposal at adjacent public sewers.
Landfill Gas Management
For safety and health reasons, a landfill gas management system is in place for a restored landfill. Landfill gas is collected and treated on site. Some of the collected gas is utilized for electricity generation for onsite use or thermal energy for leachate treatment. Excess gas is flared as far as practicable for complete destruction.
Monitoring
Regular monitoring of landfill gas, leachate, organic emission, noise, surface water, marine water, dust and odour etc are carried out.
Landscaping
The surface of the landfills is landscaped with selected species of plant.
