Disposal of municipal solid waste (MSW) is a huge problem because most developing and underdeveloped countries dispose of or dump the solid waste on open land without any protection or environmental control. To overcome this problem, conventional and engineered landfill systems are used to dump or dispose of solid waste to avoid an adverse environmental and health impacts. However, currently practiced landfill system needs to be upgraded to accommodate more advanced degradation of solid waste, leading to the establishment of a bioreactor landfill system. Bioreactor landfill involves the recirculation of leachate into the MSW to enhance the microbial process which overall increases the waste degradation and stabilization. As per the report by the Press Information Bureau in 2016, India produces 62 million tons of solid waste with an average annual growth rate of 4%. About 60% of the landmass of India is prone to earthquakes of moderate-to-high intensity. Hence, it is necessary to study the behavior of seismic design of bioreactor landfill so as to design the landfills located in the seismic impact zones to resist the earthquake. The present study is focused to analyze the slope stability of bioreactor landfill with the changes in the dynamic properties of bioreactor waste mass with time and decomposition by using PLAXIS2D a Finite Element (FE) software. The dynamic slope stability analysis of bioreactor landfill is also performed by considering several geometries (i.e., slope angles, introducing bench/step of different widths, and their combinations) with c-Phi reduction method. It is revealed that reduction in the slope angles increases the factor of safety (FoS). Further, introduction of bench/step along the slope of bioreactor landfill enhances the stability with gentle slopes. However, increase in width of bench/step does not influence in enhancing the stability of slope. Change in geotechnical properties of wastes in each layer at different decomposition ages controls the dynamic slope stability of bioreactor landfill.
