CELL BOTTOM LINING
The landfill engineering barrier will comply with USEPA design and technical requirements and will
consist of the following lining system from bottom moving upward ad as shown in the below
detail.

LEACHATE TREATMENT SYSTEM
A reliable, flexible and very robust system for the treatment of the effluent
which guarantees to meet the outlet requirements.

LEACHATE TREATMENT SYSTEM
We propose to treat the leachate using the following steps:
• A Lagoon
• An anaerobic pond
• A Membrane BioReactor (MBR)
• 2 successive aeration basins for maximal COD/BOD5 and
NH4-N reduction
• Ultrafiltration for retention of biomass
• A Reverse Osmosis (RO) plant for removal of nonbiodegradable COD-fraction,

ٍ BIOGAS COLLETION & TRAITMENT SYSTEM
Efficient and effective landfill gas management system to provide full environmental
control by coordinating and integrating gas monitoring, collection, extraction and the
gas supply to flare or utilization projects

Waste Characterization
The waste characterisation exercise has 
been completed for all three dump sites.
Inerts, soil, concrete, rocks and stones 
comprise from 63% to 91% of the wastes.
Waste Composition at Al Seeb
Other residues, 1.46%
Paper and cardboard,
1.75%
Plastics, 3.79%
Concrete, rocks and
stones, 13.07%
Wood, trees and
branches, 2.11%
Textiles, 2.90%
Inerts and soil, 74.28%
Landfill gas flow rate obtained through extrapolation
of pump test over entire site is as follows:
