Land Requirements
The area of land required for setting up any Waste Processing/Treatment facility generally depends upon the following factors:
· Total waste processing/treatment capacity, which will govern the overall plant design/size of various sub-systems.
· Waste quality/characteristics, which will determine the need for preprocessing, if required, to match with the plant design
· Waste treatment technology selected, which will determine the waste fraction destroyed/converted to energy.
· Quantity and quality of reject waste, liquid effluents and air emissions, which will determine the need for disposal/post treatment requirements to meet EPC norms.
As such, the actual land area requirement can be worked out only in the Detailed Project Report for each specific project. However, for initial planning, the following figures may be considered for 300 TPD (input capacity) Waste-to-Energy facilities:
Incineration/Gasification/Pyrolysis plants : 0.8 hectare*
Anaerobic Digestion Plants : 2 hectares*
Sanitary Landfills (including Gas-to-Energy recovery) : 36 hectares**
* Based upon typical installations
** For areas away from coast (can be more in coastal areas). This is estimated on the basis of a filling depth of 7m and Landfill life of 15 years.
