  • Formulation of a landfill pollution potential index to compare pollution potential of uncontrolled landfills

    Generally speaking, landfilling is one of the prominent methods of waste disposal around the globe, but some under-developed and developing countries still continue to practice uncontrolled open dumping of waste. These uncontrolled landfills pose a relatively high threat to the various elements of the environment in comparison with the conventional engineered landfills that are used in many ...

  • What is a wastewater treatment system and how does it work?

    For industrial companies producing wastewater as part of it’s process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate wastewater treatment system will help the facility avoid harming the environment, human health, and a facility’s process or products (especially if the wastewater ...

  • Comparing nonreinforced and internally reinforced GCL

    Water is one of the most destructive forces on the planet, eroding everything from continents to human-made wonders. Water is also a vector by which contaminants spread from landfills and other waste reservoirs. Therefore, creating effective water seals has been a top concern in construction. For many years, factory-fabricated clay products have been the barrier of choice against water and other ...

  • Biosolids ban struck down

    In 1994, Los Angeles County Sanitation Districts (LACSD) bought a 4,700-acre farm (called Green Acres Farm) in southwest Kern County for the purpose of land applying biosolids from its 11 wastewater treatment plants. LACSD land applied 800 wet tons/day at this site for several years. In 2006, Kern County voters passed Measure E on the ballot with 83 percent approval. This measure banned ...

  • Zero Waste Co., Ltd, Bangkok, Thailand - Case Study

    Thailand has a very comprehensive waste management system. Their national disposal plan is organized by the Royal Thai Government, and then distributed among the central government, regional governments, and local governments. Each agency oversees different part of the system. The central government and its ministries set standards and policies and define regulatory regimes. Provincial and ...

  • Advanced Oxidation Processes (AOPs) for reduction of organic pollutants in landfill leachate: a review

    Uncontrolled municipal landfill leachate during landfilling can seriously pollute groundwater, surface water and soil. Over the past decades, a variety of Advanced Oxidation Processes (AOPs), primarily utilising hydroxyl radicals to effect water purification, have been frequently investigated for treatment of landfill leachate. This paper first summarises the typical characteristics of organic ...

  • Persistent Organic Pollutants (POPs) in leachates from municipal landfills

    The leachates from six municipal waste landfills, located in South-eastern Poland, were studied for the presence of major, Persistent Organic Pollutants (POPs) – PAHs, Polychlorinated Dibenzo-p-dioxins (PCDDs)/Polychlorinated Dibenzofurans (PCDFs), Polychlorinated Dibenzothiophenes (PCDTs) and Polybrominated diphenyl ethers (PBDEs). The measured concentrations varied with respect to the ...

  • Application of leachate pollution indices for assessment of leachate pollution potential of landfills (a case study of an unlined landfill with lime sludge and fly ash)

    Leachates from unlined landfills cause environmental degradation and health hazards due to resultant ground water pollution. Their pollution potential can be measured on a comparative scale using leachate pollution index (LPI). The selection of index involves 18 pollution parameters, their weightages and the sub–index values. The concentrations of pollutants are obtained from toxicity ...

  • Electrochemical treatment of landfill leachate

    Electrochemical methods can offer an elegant contribution towards environmental control as electrons provide a means of removing pollutants by redox reactions. In the process of electrochemical oxidation the main aim has been to convert oxidisable species into carbon dioxide. Leachate originating in landfills is complex wastewater that could exert high environmental impact. This study aims to ...

  • Risk analysis of landfills

    A landfill has its own risks, like many other technologies. In the framework of the Polyproject 'Risk and Safety of Technical Systems' (Swiss Federal Institute of Technology, Zurich) a special methodology has been developed for analysing and assessing the different risks of a landfill. In the first main task of this task-oriented methodology, the whole procedure and the goals of the risk analysis ...

  • EU Directive on the Landfill of Waste

    The Commission has adopted a new Proposal on the Landfill of Waste. The objective of this Proposal is to reduce the impact of waste disposal on the environment. Disposal of waste is the option of last resort in the hierarchy of waste management principles as stated by the Commission in its Waste Strategy Review of July 1996. In the Review the Commission gives clear preference to minimization and ...


  • Monitoring And Analysis of Landfill Gases

    CoGDEM is the trade association representing manufacturers and service providers who are active in the field of gas detection instrumentation and environmental monitoring apparatus. Crowcon Detection Instruments Ltd was one of the founding members of CoGDEM, and in this article their Product Manager of Fixed Systems, Andy Avenell, gives an update on Landfill Gas. Landfill is by far the most ...

  • Landfill leachate treatment

    Landfills are categorized by regulations in three types: industrial, municipal, and hazardous. Individual landfills may be further differentiated by the types of waste which they accept. All landfills are required to be capped, usually occurring at the end of each day. The cap is typically 6-8” of soil. The cap reduces odor and loss due to wind. At the closing of the landfill, a permanent ...

  • Major Considerations in Landfill Closure

    Preparing for the closure and long-term care of a municipal solid waste landfill (MSWLF) can be an inordinate undertaking. Whether public or private, all landfills eventually reach the end of their active lifecycle. Before closure, a landfill must meet a series of criteria as determined by Subtitle D of the Resource Conservation and Recovery Act (RCRA). Following closure, those same regulations ...

  • Zero landfill is not zero waste

    THE Zero Waste movement is more than just a vision. It is a movement that is actually changing the world. To prove it, I recommend visiting GreenBiz.com and in the search box type “zero waste.” You will be amazed, as I was, at the tsunami of business activities over the last couple of years related to the idea of totally eliminating waste from our manufacturing, distribution and ...

  • Landfills Expand Energy Output

    HIGH fossil fuel prices and growing concern about global climate change are creating favorable conditions for landfill gas energy (LFGE) projects. Notably, endorsement of LFGE by Federal agencies and many states as a form of “green” power has enabled LFGE developers to earn premiums for electricity marketed through green power programs, and to benefit from expanded federal tax credits for ...

  • Treatment of landfill leachate by effective microorganisms

    Five dominant strains, capable of treating leachate effectively, were isolated. The results showed that the removal efficiency of COD by using the mixed strains was higher than the pure strain, reaching 46.8%. The optimal inoculum concentration and the treatment time were 10.0% and 120 h respectively. The removal rate of COD reached the maximum at the temperature of 35°C and pH of 7.0. The ...

  • Assessment of landfill gas and methane emission at Keru landfill site, Jodhpur (India)

    Jodhpur is densely populated and urbanised city of Rajasthan state. The population of the city is considerably increased in past few decades due to rapid urbanisation and industrialisation within the city. Presently inhabitants of Jodhpur generate about 392 t/d of MSW. MSW management has remained one of the most neglected areas of the municipal systems. About 70–80% of generated MSW is collected ...
