8 Waste Management
8.6.1.4 Dumps and Landfills
A landfill is a site for disposing of waste materials by burying them. It is the most
common and oldest form of waste treatment. Some landfills are also utilized for
waste management as temporary storage. Unless there is stabilization, these areas
could experience severe shaking. High winds could lift some part of the landfill, and
cause a wave or tremor that shakes the ground as wind mixes with the area below the
cap. Wind could carry the odor from the landfill into other areas, thus making people
who may be living nearby to be uncomfortable because of the smell. However,
well-managed landfills meet certain predefined conditions: confining waste to the
smallest area possible, compacting waste to minimize volume, and covering waste
with soil layers or other material types, including fine particles and woodchips
(Orlova et al. 2017). The first advantage of landfills is that they are the most costeffective means for waste disposal, particularly in nations that have large open
spaces. Whereas incineration and resource recovery need extensive infrastructural
investments, landfills require fewer costs, thus enabling them to compete favorably.
Additionally, landfill gas can be upgraded to natural gas through landfill gas
utilization to generate revenue. Furthermore, landfills make use of specific locations
that can be monitored. However, landfills are also sources of various environmental
problems. They disrupt the infrastructure, such as damaging access roads. They are
also a source of environmental pollution, including the contamination of aquifers,
soil, or groundwater.
How can wheel washing systems be used in mitigating the pollution of local
roads and infrastructure?
Sanitary landfills are the most common solution for waste disposal. They are
designed to minimize or eliminate the risk of public health hazards brought about
by waste disposal. Sanitary landfills are located in places where land features act
as natural buffers between the landfill and the environment (Orlova et al. 2017).
For example, a landfill area could consist of clay soil that is resistant to hazardous
wastes, thereby preventing susceptibility to water pollution. Using sanitary landfills
poses the least environmental and health risk. However, the costs associated with the
establishment of such landfills are relatively higher compared to other methods of
waste disposal. Notably, various precautions have to be considered prior to operating
a sanitary landfill. First, appropriate site selection is crucial. Second, they should
be situated far from rivers, flood plains as well as groundwater recharge zones.
The third consideration is the topographic relief and depth of the groundwater
table. In addition, the landfill’s base needs to have impermeable clay or plastic
material lining. Appropriate drainage systems also need to be installed around
landfills to check water accumulation (Orlova et al. 2017). Finally, monitoring wells
for potential groundwater pollution need to be installed. The main advantages of
