Abstract:

Within the UK implementation of the European Union Landfill Directive (1999) has led to the diversion of biodegradable waste (BW) from municipal solid wastes away from landfills. It has been widely anticipated, but thus far not verified, that the diversion of BW and consequent reduction in BW reaching landfill would lead to a change in the degradation processes occurring within landfills and that this would be reflected in an altered evolution in leachate chemistry compared to pre-Directive landfills. This paper provides evidence based on leachate chemistry from two operational landfills toget

Landfills are the most broadly used methods for the disposal of municipal solid waste (MSW). Leachate can be contaminated with pollutants that may pose a threat to the landfill surrounding namely soil, groundwater and surface waters.. Examination of leachate composition is determinative in long-term impact of landfills on the environment and human health. Moreover, it is essential to assess such prior knowledge for prevention of negative outcomes. The evaluation of the seasonal changes of landfill leachate and rainwater composition is presented in this paper. Research samples of leachate and r

Abstract:

The characteristics of leachate from landfills vary according to site-specific conditions. Leachates from old landfills are often rich in ammonia nitrogen, posing potential adverse environmental impacts in the case of uncontrolled discharge. At landfills where leachate recirculation is practiced, leachate ammonia concentrations may accumulate to higher levels than during the single pass leaching. Using leachate recirculation with system modifications, separate aerobic and anoxic zones for nitrification and both autotrophic and heterotrophic denitrification can be provided.

Abstract:

Under the newly implemented waste management policy in European Union countries, sanitary landfilling constitutes the fourth and the least preferred of the alternative management options for the disposal of solid urban wastes. Landfills generate emissions over long periods, often longer than a lifetime. The longest lasting emission is leachate: leachate production and management is now recognized as one of the greatest problems associated with the environmentally sound operation of sanitary landfills.

Background In certain countries, including Poland, polyvinyl chloride (PVC) waste, together with di-2-ethylhexyl phthalate (DEHP) contained within (up to 60%), is mostly directed to municipal solid waste (MSW) landfills. From there, over time, it is released from the polymer matrix and can migrate with landfill leachate into the environment. The amount of DEHP placed on the Polish market since the start of industrial production and the prevalent landfilling disposal of PVC waste in Poland, indicate that DEHP pollution can increase risk factors in the future.

According to estimates, around 40 % of the world's plastic waste production is buried in landfills, which are still a widely used approach for waste disposal. Waste undergoes a number of physical, chemical, and biological changes after being landfilled, producing landfill leachate, a highly contaminated effluent. These complex physical, chemical, and biological processes that occur in landfills also cause plastics to break into smaller fragments called microplastics (MPs) which are accumulated in landfill leachate due to their small size.

Most municipal landfills are constructed and operated with exposure to intermittent rainfall. Infiltration of rainfall, together with the inherent moisture content of landfilled wastes, promotes leachate production and accelerates rates of conversion of waste constituents. As these conversion processes proceed, waste stabilization occurs, leachate quality changes, and biogas is released in correspondence with the prevailing phase of stabilization. The intensities and temporal and spatial dimensions of these phases are waste-specific, a function of landfill design and operational strategy emplo

Abstract:

Despite initiatives for enhanced recycling and waste utilization, landfill still represents the dominant disposal path for municipal solid waste (MSW). The environmental impacts of landfills depend on several factors, including waste composition, technical barriers, landfill operation and climatic conditions. A profound evaluation of all factors and their impact is necessary in order to evaluate the environmental hazards emanating from landfills. The present paper investigates a sanitary landfill located in a semi-arid climate (Tunisia) and highlights major differences in quantitative and qual

Abstract:

Accelerating the waste mineralization is of great significance to control the settlement of transportation facilities nearby landfills. Mineralized waste can also be used as road construction materials to recycle waste resources and reduce the construction cost of transportation facilities. A biochem-hydro-mechanical-solute migration-coupled model for describing complex interactions in landfills with high kitchen waste content has been developed. The proposed model can consider large leachate production and landfill gas entrapment due to the fast degradation of kitchen waste. The quantitative

Abstract:

Leachate and landfill gas are the main contaminants produced by modern sanitary landfills. The leachate easily leads to clogging in the leachate transportation pipe, and the landfill gas can be used as renewable energy after the removal of CO2. The study aims to investigate the removal of the major scale forming ion of Ca2+ in leachate using raw landfill gas before pipe transportation. The research demonstrated that, under the given experimental conditions, the removal rate of Ca2+ in the leachate was positively correlated with the pH value of the leachate, and negatively correlated with the i

Abstract:

Rapid population growth has contributed to increased solid waste generated in Malaysia. Most landfills that have reached the design capacity are now facing closure. Taman Beringin Landfill was officially closed, so the Taman Beringin Solid Waste Transfer Station was built to manage the relocation, consolidation, and transportation of solid waste to Bukit Tagar Sanitary Landfill. Leachates are generated as a consequence of rainwater percolation through waste and biochemical processes in waste cells. Leachate treatment is needed, as leachates cause environmental pollution and harm human health.

Abstract:

Leachates from landfills constitute a very complex environmental matrix with potentially toxic properties for both the environment and humans. Due to this fact, toxicological tests were carried out on landfill leachate (LL) obtained from the local landfill in Hryniewicze (Poland). The analyses included physicochemical studies of leachates and their impact on soil and plants, and studies conducted in bacterial models and human cell models. The results obtained indicate high contents of metals and organic matter, especially dangerous PAHs, in the tested leachate. This results in the influence of

Abstract:

A landfill is the most common waste disposal in Indonesia, yet the implementation and operation of landfills are still far from optimal due to lack of funding and management failure. Moreover, landfill was operated as unmanaged open dumps. This situation could enhance the likelihood of plastics pollution through various transport of plastic waste from landfill sites, including microplastics release from leachate. This study was focused on the evidence of microplastic pollution originating from the landfill. Leachate sampling was conducted at two landfills, an inactive landfill called Leuwigaja

Abstract:

Landfill leachates were found to exhibit reducing properties whereby chromium(vi) was converted into chromium(iii). The reduction is attributed to a microbial process in the presence of high concentrations of organic materials in the leachates. Nonputrescible landfill leachate (NPLL) was found to reduce CrVI to a lesser extent than the municipal landfill leachate (MLL). Microbial reduction of CrVI was also found to occur under alkaline conditions in extracts from a cementitious waste. A 55% reduction of CrVI was achieved by enriching the extract with bacteria and organic material.
