Secured landfills:
Secured landfill at KEIL is constructed in phases as per requirement. Each cell of the landfill on filling up with waste is capped as per guidelines issued by Central Pollution Control Board.

Engineered landfills are built as per drawings approved by IIT, Delhi and Kerala State Pollution Control Board. Each cell is inspected by Independent Consultant before disposal of waste. Currently KEIL has constructed seven cells for waste disposal out of which four cells are capped and presently waste is disposed in 5th, 6th & 7th Cells. As of January 2023, KEIL has received and disposed a total quantity of 6.18 Lakhs MT waste in the secured landfill.

In view of the climatic and soil conditions at the site, a double composition liner system is adopted for construction of landfill in KEIL.
KEIL is required to maintain the landfill and monitor for its satisfactory performance for a period of 30 years after closure.

Leachate collection system
Leachate is collected by a slope in the landfill bottom liner, which eventually flows into a collection sump. The collected leachate is pumped out and is transferred to a leachate treatment system.

The Leachate treatment system includes a Multiple effect evaporation plant and a Reverse Osmosis (RO) Plant.

Transportation:
The transportation of the hazardous and other waste is undertaken in accordance with the provisions of rules made by the Central Government under the Motor Vehicles Act, 1988 and the guidelines issued by the Central Pollution Control Board.

KEIL uses own as well as hired dedicated vehicles for transportation of hazardous waste from waste generators. All these vehicles are fitted with GPS.

Manifest system (Form 10) is used for transportation of hazardous waste in accordance with provisions of Hazardous and Other Wastes (Management and Transboundary Movement) Rules.

Godown and Stabilisation:

  • 900 sq.m Godown and 900 sq.m physical treatment area are built in KEIL for catering to the waste storage and treatment so as to make it harmless or less hazardous. The waste stabilization is undertaken in specially designed pit equipped with suction hood and scrubbing system to ensure clean environment in the stabilization area.
  • 4800 sq.m Monsoon Shed is built to store waste received during the monsoon season in Kerala. The bottom of the Shed is a landfill pit constructed as per Central Pollution Control Board guidelines for land fill construction. Submerged pumps are installed to extract leachate collected at the collection sump for further treatment.
