“…7 This leads to an increased effect on the environment when compared to other waste management strategies such as recycling or anaerobic digestion (where appropriate). For example, contaminated water from landfill finds its way to wells used for drinking water and agriculture, 8,9 air pollution from landfill affects surrounding wildlife [10][11][12] and landfills increase the risk of wildfires, which in turn create more harmful emissions. 13 There is no contribution by households to the costs of refuse collection and management in Saudi Arabia.…”

The systems-engineering context of the solid waste disposal problem is discussed with a focus on the issues in Saudi Arabia. A methodology was developed for dividing the system of interest into a set of weakly-coupled sub-systems that interact with the narrow system of interest. A model of the narrow system of interest, in this case the municipal solid waste (MSW) system of Saudi Arabia, was then created and validated.The development of this mathematical model is described and is used to investigate a range of scenarios for the future of Saudi Arabia's MSW system with a time horizon of 30 years. The most effective method uses anaerobic digestion, incineration and recycling to reduce the total mass to landfill over the 30 years by 73% when compared to the default scenario (no action taken). In the final year of the simulation, this method reduces the total annual mass to landfill by 69% when compared to a reasonable source reduction strategy. The energy generated by incineration, is shown to contribute a maximum of 2.3% to the Kingdom's annual energy production. Lifecycle analysis shows that the best waste management method produces a DALY (disability life year) score which is 2% of the current strategy, even if moderate source reduction is employed. The two newly suggested scenarios are shown to have a net positive impact on the environment due to the recycling of a large part of the waste stream, preventing acidification/eutrophication due to the manufacture of virgin goods.

“…Compacted clay liners (CCLs) and geosynthetic clay liners (GCL) are barrier systems in landfill design as their hydraulic conductivity is very low. Laboratory and field investigations have shown that the application of either the CCL or GCL while underlain by a geomembrane could effectively prevent the advection and diffusion of the contaminants into the surrounding environment [5,6]. CCL is composed of thick compacted layers of soil having thickness of 0.80 to 1.0 m. The efficiency of landfills largely depends on the hydraulic performance of clay liners.…”

Evaluation of Bentonite Mixed Indigenous Clays for Development of Clay Liners

et al. 2020

This study presents experimental investigation of indigenous clays mixed with Bentonite to assess their suitability in potential use as clay liners. Soil samples with 0, 4, 8, and 12% Bentonite content from three different sites in Peshawar region were tested for various geotechnical properties. Grain size distribution, specific gravity, Atterberg limits and free swell were found through laboratory tests using appropriate ASTM procedures. Maximum dry density and optimum moisture content were calculated using Atterberg limits in available relationships. Finally, one dimensional consolidation tests were conducted to find relevant parameters for calculating hydraulic conductivity. A decrease in specific gravity, increase in free swell, and in optimum moisture content, decline in maximum dry density and hydraulic conductivity was observed with increase in Bentonite content across all three soil samples. During free swell, the soil clusters become larger leading to formation of floccules resulting in the narrowing of inter-particle space and thus blocking of permeable paths. It is concluded that 8% Bentonite content by weight yields a suitable mixture for a clay liner that has hydraulic conductivity in the range of recommended limits.
