This project presents the analysis of the volcanic clay soil from Grik, Perak, the study of
its characteristics and its suitability to be used as a landfill liner.
A landfill is an engineered method for land disposal of solid or hazardous wastes in a
manner that protects the environment. Within the landfill biological, chemical, and
physical processes occur that promote the degradation of wastes and result in the
production of leachate and gases. And thus, a landfill design and construction must
include elements that permit control of this leachate/pollutant and gas. The major design
amongst other parameters will include the design of a liner.
This liner should be strong and be able to prevent any penetration to the ground water so
not to contaminate the ground, thus, it should also be a good pollutant absorber. Should
it be a particular clay liner, then such characteristics should be possessedb y it.
The problem with the ordinary liners such as the geosynthetic liners is that it may
permeable and it doesn't last for a long period before it deteriorates. This is the problem
that this study / research is trying to solve in coming up with a better landfill liner.
The methodology of this project involves testing on the hydraulic conductivity of the
clay, analysis of the XRF and AXRD and also a test on the adsorption of pollutants by the
clay. All these where carefully analyzed so as to see if the clay is suitable to be used as a
landfill liner. The hydraulic conductivity of the clay is the most crucial / primary
requirement for a clay liner, and in this case it proved to be so small, and thus meeting
the requirement of a liner according to the European Union standards on land filling of
waste products.
