The leachate pollution index (LPI), a technique to quantify the contamination potential of landfill leachate, was developed in 2003. Since then, numerous factors have challenged the relevance of the LPI, including advancements in technology, the long-term reliability of these indicators, the incidence of emerging contaminants, and the

Landfill techniques are dependent upon both the type of waste and the landfill management strategy. A commonly used classification of landfills, according to waste type only, is described below, together with a classification according to landfill strategy.

In this article, we take a look at an Ordinary Differential Equation model that describes the bacteria''s role in anaerobic biodegradation dynamics of domestic garbage in a landfill. A nonlinear Ordinary Differential Equation system is used to describe biological activities. In the current study, the Levenberg–Marquardt Backpropagation Neural

Managing leachates from landfills in India is an important economic and environmental concern. Due to the exponential growth of population, industrialization and urbanization, several types of byproducts have been generated from day-to-day life. These byproducts are dumped in a haphazard or unempirical manner into the open space,

The application of GIS, MCDM techniques, and landfill site suitability map is not new, and several studies Fig. 6 a GPS location defining suitable and unsuitable landfill sites, b accuracy

Specific tools and techniques that can be used for landfill monitoring, with particular focus on methods that enhance monitoring and maintenance procedures at landfills practicing sustainable technologies. Key monitoring parameters and methodologies covered include liquids (e.g., volume, depth, pressure, chemical composition), landfill gas (e.g

Finally, this article emphasizes the future opportunities for integrating advanced techniques to explain landfill chemistry explicitly. In conclusion, this paper will provide a comprehensive vision of the diverse dimensions of landfill biological and biogeochemical reactions and dynamics to the scientific world and policymakers.

Landfilling is widely used for solid waste disposal worldwide. •. Waste decomposition during landfilling generates landfill leachate and landfill gas. •.

Designs may vary, but there are three basic methods of building a sanitary landfill: area method, trench method, and ramp method. AREA METHOD. The area method is best-suited for sites where no natural slopes exist. This method can be adapt-ed, however, to ravines, valleys, quarries, or old surface mines.

Sanitary landfill is the most popular way to dispose solid wastes with one major drawback: the generation of landfill leachate resulting from percolation of

The DiAL technique also provides spatial measurements of emission gases in landfill sites, which may be used in combination with mass balance box modelling for precise flux estimates. To obtain entire emissions for a large landfill, micrometeorological measurements, the tracer gas dispersion method, inverse dispersion modeling, and radial

Abstract. The solid waste disposal problem is a well-known global environmental issue, wherein landfilling and open dumping are the most widely followed practices. The production of toxic liquid, leachate, is a significant issue with landfilling practices. This leachate needs to be treated carefully before its disposal in the environment.

This paper systematically reviews LL as a source of MPs to the environment, the formation of MPs from PW in landfills, associated environmental risks, and detection techniques of MPs in LL. The manuscript also addresses possible solutions, emphasising recent technical advances in removing MPs from landfills and the

Landfill siting is a hard and complex process. For this reason, it is considered as one of the major problems in waste management. This is due to the fact that a number of factors are involved within the process such as such as inhabitants'' growth, rapid economic growth, living standards improvements, etc. In Iraq, landfill siting does not

Gu et al. (2019) compared these techniques, concluding that the AD is the preferred technology for energy recovery from landfill wastewater. In anaerobic digestion, biodegradable organic matter, through a multistage and complex process, is biochemically converted into biogas, which is primarily composed of methane and carbon dioxide and

D. Reinhart, T. Townsend. Published 23 September 1997. Environmental Science, Engineering. TLDR. This book discusses the evolution of landfills for Waste Management Landfills as Bioreactors as well as the design of Landfill Treatment and Reclamation Strategies, and some of the strategies used to achieve this goal. Expand.

As a result, vegetation stress proved to be a good indicator for illegal landfill detection, and RS proved to be a successful technique for landfill identification. Vegetation stress induced by the presence of dump sites is also an element of study in [ 21 ], in which several multispectral vegetation indexes were compared to identify the most

ML technique was also utilized for dosing biopolymers and coagulants used for the treatment of landfill leachate (Matovelle et al., 2023). Suspended solids in leachate were effectively removed using both organic and inorganic coagulants, achieving impressive removal rates of 98% for suspended solids and 70% for organic matter.

Here, we review the impact of landfill conditions such as construction, geometry, weather, temperature, moisture, pH, biodegradable matter and hydrogeological

The major design components of a landfill are sub-base, liner, leachate management system, gas management system, final cap, and stormwater management. Monitoring is an important task

Landfill leachate is commonly heavily contaminated and consists of high amount of organic compounds, inorganic salts, toxic gases, halogenated hydrocarbons, and heavy metals that exerts a serious threat to public health and the environment. Thus, it requires treatments before direct release into receiving waters. Selecting the efficient

Landfill leachate has a wide range of negative environmental effects and contaminates groundwater on a massive scale. This leachate contains highly toxic pollutants such as heavy metals, solids, BOD, COD, ammonia and TOC. This versatile nature of pollutants cannot be treated with a single treatment technique.

A landfill site, also known as a tip, dump, rubbish dump, garbage dump, trash dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and

A landfill is defined as a well-engineered depression in the ground used for the disposal of solid waste. Landfills contain a variety of wastes, mainly consisting of

Nevertheless, the sanitary landfill technique remains a cost-effective option for treating and disposing of solid waste, responsible for the majority of municipal solid waste disposal globally. Planning and design of landfills need to consider previous factors, a crucial consideration to avoid environmental risks.

1. Introduction Engineered landfill (EL) techniques are widely used for the scientific dumping of industrial waste, municipal solid waste, and hazardous waste securely (Osra et al., 2021) contrast, non-engineered landfill (NEL)

Furthermore, combined treatment techniques for treating landfill leachate, owing to its high chemical oxygen demand and concentrations of ammonia and low biodegradability, have been reported

During the operation of landfills, leachate recirculation and aeration are widely applied to accelerate the waste stabilization process. However, these strategies may induce high pore pressures in waste, thereby affecting the stability of the landfill slope. Therefore, a three-dimensional numerical analysis for landfill slope stability during
