The key aspects of landfill operation that remain unresolved are the extended timescale and uncertain funding of the post-closure period. This paper reviews the topic and proposes an economic instrument to resolve the unsustainable nature of the current situation. Unsustainability arises from the sluggish degradation of organic material and also the slow flushing of potential pollutants that is...

Vast quantities of H2S emitted from landfill sites require urgent disposal. The current study focuses on source control and examines the migration and conversion behaviour of sulfur compounds in two lab-scale simulated landfills with different operation modes. It aims to explore the possible strategies and mechanisms for H2S endogenous mitigation inside of landfills during decomposition. It is ...

Uncontrolled growth of the urban population in developing countries in recent years has made solid waste management an important issue. Today municipal solid waste management (MSWM) is one of the most challenging issues in urban cities, which are facing a serious pollution problem due to the generation of huge quantities of solid waste. This results in development of environmentally sustainable...

Waste management practices can impact greenhouse gas (GHG) emissions by affecting energy consumption, methane generation, carbon sequestration, and non-energy-related manufacturing emissions. This paper examines GHG emissions and sinks, from a life-cycle perspective, for selected paper, glass, metal, and plastic materials comprising about one-third of municipal solid waste (MSW) generated in th...

In recent history the volume of electronic products purchased by consumers has dramatically escalated. As a result this has produced an ever-increasing electronic waste (E-waste) stream, which has generated concerns regarding the E-waste's potential for adversely impacting the environment. The leaching of toxic substances from obsolete personal computers (PCs) and cathode ray tubes (CRTs) of te...

SUMMARY: Landfill aftercare lasts until the authorities consider a landfill not to pose a threat to human health and the environment. To evaluate aftercare, it is necessary to gain an understanding of the waste emission behaviour, the long-term barrier performance, and the impact of substances released to the environment. Because appropriate models for emissions from waste are highly dependent ...

Abstract Increase in population and technology advancement leads to higher generation Municipal Solid Waste (MSW). The current method of disposing solid waste by incineration process, which operates at high capital, Operation maintenance cost emission toxic gases. This paper discusses the process design model MSW gasifier minimize heating requirement when compare with conventional for a disposa...

Leachate generation is among the main challenging issues that landfill operators must handle. created when decomposed materials and rainwater pass through waste. carries many harmful pollutants, with high concentrations of BOD, COD, colour, heavy metals, ammoniacal nitrogen (NH3-N), other organic inorganic pollutants. Among them, NH3-N are difficult to be completely eliminated, especially a sin...
