Management strategy of landfill leachate and landfill gas condensate
Studies were conducted to evaluate the impact of landfill leachate discharge on the operation of waste water treatment plants (WWTPs). Two aspects of interferences were found: one is UV quenching substances, which are bio-refractory and able to penetrate the biological treatment processes, …

Conversion of landfill composite to activated carbon as an approach to sustainable landfill management
Landfilling of municipal solid waste is a major waste disposal method, especially in developing countries despite its pressing environmental challenges. Reuse of the landfill composite has been suggested as a sustainable management option that could limit its negative effect. This research …

Groundwater contamination at a landfill: a case study of coastal park landfill, Cape Town
The extent of groundwater pollution from landfills varies throughout the year. Studies have shown that rainfall is the greatest contributor to nutrient pollution in groundwater. Therefore, groundwater monitoring that is based on predetermined schedules and fails to consider the effects of rainfall, …

Mechanics of biocell landfill settlements
Prediction of landfill gas generation and settlements are of concerns in design and maintenance of biocell landfills. Accurate settlement prediction is essential for design of piping systems used for the delivery of re-circulated leachate and recovery of landfill gas. Landfill settlement is the …

Analytical Methods of Testing Solid Waste and Leachate to Determine Landfill Stability and Landfill Biodegradation Enhancement
… to investigate municipal solid waste (MSW) landfill stability parameters and landfill leachate properties to determine how solid waste and leachate characteristics can be used to describe stability. The primary objective was to determine if leachate properties could be used to determine …

Managing landfill leachate using biological approach
Poor management of landfill would accompany with the production of leachate wastewater that would lead to environmental and public hazards. Hence, a study related to the use of biological treatment for leachate management was carried out.The research objectives of this research study were …

Landfill containment and waste management systems
This thesis report addresses the role of landfill disposal within the framework of the modem Integrated Solid Waste Management (ISWM) hierarchy.<br/><br/>The aims of the research are presented in the context of a literature search and postal questionnaire survey to identify trends in United Kingdom …

Modern landfill leachates – quality and treatment
… stricter regulations, most notably the European Landfill Directive 1999/31/EC. In Sweden, landfill tax and a ban on the landfilling of waste with total organic carbon content over 10 % have diverted large amounts of waste from landfills. The biogeochemistry of landfills has changed due to their …

Performance Enhancement of Aerobic Landfill Bioreactors
… cells has several advantages over traditional landfills such as, increased rate of waste stabilization and reduced greenhouse gas emissions. However, the operation of aerated waste cells is fraught with uncertainties because it has not been thoroughly studied to overcome all the technical …

Performance Reliability of Landfill Lining Systems
… is a critical component in the infrastructure. Landfill facilities are one of the most commonly used means of managing waste. Landfills are equipped with lining systems to minimize the rate of leakage from the facility to the surrounding soils and groundwater. The objectives of this thesis are …

Llefa Lame: [Re]imaging Soshanguve Landfill
… north townships gather daily at municipal landfills to collect, sort valuable and recyclable waste in exchange for cash. This study focuses on informal waste re-claimers working conditions at Soshanguve landfill and Soshanguve township communities residing in the vicinity of an active …

Uncertainty in incinerator and landfill risk assessments
… communication of uncertainty in incinerator and landfill human health risk assessments. This aspiration has been in response to finding a limited and ambiguous use of the term 'uncertainty', a lack of consensus in its definition and nomenclature, and its perfunctory review in risk assessmentsI.n …

A Hazard Assessment of a Landfill Site
Trecastell landfill site is an open-cast site to which filter cake containing calcium sulfate was deposited as the only known industrial waste. Geological mapping of the site was carried out followed by search bar surveys to determine the area where passive venting of methane, carbon dioxide and …

Evaluation of Contaminant Containment at Regina Landfill
Landfill and waste containment facilities are routinely constructed on natural or engineered low permeability barriers placed above or within the vadose zone to prevent contaminant migration into the groundwater system. Numerical estimates of design lives for assessment of barrier system …

Landfill design, construction and non-invasive monitoring
… order to assess their applicability for use in landfill design, construction and monitoring. Firstly, an assessment is made of QA procedures during liner construction through the detailed evaluation of two case studies. Construction QA procedures on-site are compared to available guidelines. The …

Nitrification of Landfill Leachate by Biofilm Columns
Landfill leachate characteristics vary depending on the operation type of the landfill and the age of the landfill. At landfills operated as bioreactors, where leachate recirculation is practiced, leachate ammonia nitrogen concentrations may accumulate to extremely higher levels than during single …

Evolution and degradation pathways of landfill leachate DOC and detection of groundwater landfill-leachate contamination using compound-specific isotope analysis
… compounds of DOC in leachate from the Trail Road Landfill (TRL) site, Ottawa, Ontario, in order to better characterize its biogeochemical and isotopic evolution during degradation; to determine methanogenesis pathways; and to identify characteristic tracers for recognizing potential of the …

Facultative Bioreactor Landfill: An Environmental and Geotechnical Study
… Solid Waste treatment is known as bioreactor landfill technology. Bioreactor landfills are sanitary landfills that use microbiological processes purposefully to transform and stabilize the biodegradable organic waste constituents in a shorter period of time. One of the most popular types of …
