“…Heavy rainfall (Merry et al, 2005) is another cause. The accumulation of landfill gas (Lavigne et al, 2014) and landfill plastic both also cause an increase in leachate level (Blight, 2008). A high leachate level in the landfill will increase the pore water pressure and reduce the shear strength parameters of the MSW, affecting the stability of the landfill.…”

This study summarized global examples of landfill slope instability over the past 40 years, then selected 62 cases from 22 different counties to analyse the primary factors causing landfill instability. Three slope instability modes in landfill were categorized according to the position of the slip surface: (1) slip surfaces generated inside the waste pile; (2) slip surfaces that pass through the foundation soil; and (3) slip surfaces that occur along the interface between the bottom liner and the municipal solid waste (MSW) pile. These three types of slope instability modes account for 69.4%, 19.32% and 11.28% of all slope instability, respectively. Moreover, five primary causes of landfill instability were identified. A high landfill leachate level was the dominant cause, accounting for 40.32% of cases. This was followed by inadequate compaction of MSW, which accounted for 22.58% of cases, and insufficiently bearing capacity of the foundation, which accounted for 19.35% of cases. Moreover, low shear strength of the liner–MSW interface and rapid release or deflagration of landfill gas were critical factors affecting landfill stability. Factors of safety were calculated using GeoStudio software for selected landfills in China (Maoershan and Xiaping) and Sri Lanka (Meethotamulla). Results from this study are expected to contribute to the prevention and control of landfill failure.

“…On mass, piles of waste can also have catastrophic consequences if they become unstable (Lavigne et al, 2014). There have been multiple incidents over recent decades that have resulted in the deaths of many hundreds of people who work on dumpsites or live nearby (Blight, 2008;Lavigne et al, 2014;Yoshida, 2018). It is worth noting that many dumpsite workers also live in their place of work, along with their families, including children, and that those who live closest to dumpsites may also be the poorest and least able to recover or mitigate the negative impacts of their proximity to these facilities (Raviteja and Basha, 2017).…”

Disposal on land has persisted as the most predominant form of waste disposal for millennia and despite advances in modern engineered landfills, large quantities (405 Mt y-1) of collected municipal solid waste (MSW) are still deposited and concentrated in open, uncontrolled dumpsites throughout low- and middle-income countries (LIMICs) worldwide – a key form of waste mismanagement. These pose major threats to the health and safety of surrounding populations and mainly waste pickers who across the Global South target dumpsites to salvage and recycle under minimal protection measures. Here, we conducted an adapted PRISMA systematic review, distilling over 3,000 papers into 40 core sources from 22 countries, to critically assess the evidence on the associated risks. We identified prevalent hazard-pathway-receptor combinations and subsequently scored, compared and ranked the relative risk of exposure to harm experienced by various actors in land disposal sites. Our assessment indicates high risk levels experienced through interaction with medical waste, emissions from waste combustion, and critically through the fatal risk of waste slope failure, claiming the lives of at least (on average) of 34 people per year since 1992. Despite the strong anecdotal signals on the generic nature of the health and safety challenges at hand, many of the sources lack critical information with which to determine and link causality of health effects with the existence, or even exposure to emissions or other hazards. Yet, our critical analysis clearly demonstrates an unacceptable potential for damage to human health and safety; alerting us on the need to close, and immediately manage risks at dumpsites, preventing harm to some of the worlds’ poorest inhabitants. Our aspiration is that quantification and mitigation of risks from dumpsites attracts substantial and scientifically robust efforts.

“…Landfill slope failure at MSW dumpsites can be found in previous studies, wherein six reported cases between 1993 and 2005 resulted in approximately 500 deaths and significant economic loss (Blight, 2008;Blight and Fourie, 2005;Eid et al, 2000;Kjeldsen and Fischer, 1995;Kocasoy and Curi, 1995;Merry et al, 2005;Mitchell et al, 1990). The deadliest event in history killed 278 people in Manila, Philippines, in 2000, and the second deadliest event killed 143 people and buried 71 houses on 21 February 2005 at the Leuwigajah dumpsite near Bandung, Indonesia (Lavigne et al, 2014).…”

Abstract. A catastrophic flowslide occurred at the Hongao dumpsite on 20 December 2015 in the Guangming New District of Shenzhen, China. The flowslide caused 77 causalities and damaged 33 buildings. In the absence of extreme weather conditions and seismic activity, the causes of the failure were analyzed on the basis of multi-temporal remote-sensing images, site investigation, in situ tests, laboratory tests, and numerical analyses. Site investigations showed that the volume of the displaced material was 2.32 × 10 6 m 3 and the volume of the pre-failure waste filling was 6.27 × 10 6 m 3 . The flowslide was characterized by high travel velocity and long runout distance. The displaced material was primarily a mixture of silty soil and construction and demolition waste with water content of 17.3-42.4 %. The primary causes of the failure were concluded to be the following: (1) groundwater flow had stagnated in the dumpsite due to drainage system failure and the underlying impermeable granite stratum; (2) the accumulation rate and total volume of the waste filling was in exceedance of the design capacity. The flowslide may be ascribed to the development of excess pore-water pressure as evidence of liquefaction was observed at several locations, and it is postulated that such phenomena were related to the surcharge loads imposed by the unregulated disposal activities.
