Parametric study of stability in landfills due to changes in waste composition
Parametric study of stability in landfills due to changes in waste composition
The modern trend in waste management in most developed countries in Europe and the world is based on waste reduction, reuse and recycling, while landfilling is considered the least desirable method in the waste management process. Despite this trend, landfilling is still the leading method of waste disposal in most countries. Considering the increasing amount of waste, even if all methods to reduce the amount of waste are used, there will still be a need to build a landfill. Waste is a heterogeneous material whose physical, mechanical and chemical properties are highly dependent on the composition of the waste, so even minor changes in composition can affect the change in these properties. In Croatia, in the process of approaching European Union standards, the composition of disposed waste has changed significantly, primarily due to the fact that biowaste, plastic waste and paper are increasingly separated from total municipal waste. The separation of these constituents significantly affects the density, moisture and granulometric composition of the deposited waste, which in turn affects the stability and deformations of the landfill body itself, as well as the stability of the protective layer system. In this work, the effects of changes in the physical and mechanical parameters of the landfilled municipal waste on the stability of the landfill body were analyzed.
