  • Landfill grinding system

    A landfill needed a way to reduce their waste stream volume, increase the life of their landfill, and recover a recyclable, marketable product. Wood and yard waste material comprise up to 20% of their entire waste stream volume. Processing and recycling this material will extend the life of the landfill by 20 years. They chose WSM's Model 4864BH Horizontal Hogging System with a customized feed ...

  • Seropédica landfill

    The Seropédica landfill is located on the outskirts of Rio de Janeiro. Since the closure of the 130-hectare big Gramacho landfill, Seropédica now receives over 6,000 tons of waste per day. Seropédica is the most modern solid waste treatment center in Brazil and Hofstetter has been awarded the biogas treatment process, as well as the set up of a flaring system at the landfill. ...

  • Landfill Capping Systems: An Introduction to Options

    Geomembranes, predominately linear low-density polyethylene (LLDPE), have been used for landfill caps for decades. Waste Management World has noted how,” Generally they have performed extremely well but, not unexpectedly, there have been a few exceptions that have guided us in developing even better systems.” Currently, there are four commonly used options for landfill caps, each with ...

  • Combined Landfill Gas and Leachate Extraction Systems

    There is currently a shift of emphasis in the approach to treatment of landfill gas and leachate. Until recently, there have been two disparate schools of thought concerning the collection and disposal of these two by-products of organic waste degradation within the same bio-reactor. The tendency in the past has been to study gas and leachate as separate problems each of which requiring a ...

  • Oxidation System for Sanitary Landfills & Recycling Centers

    A major US waste handling company operates a large landfill in Florida, and in 1992, when Hurricane Andrew struck southern Florida, the landfill saw a huge increase in the amount of C&D waste. Shortly after this, the levels of H2S started dramatically rising. This company evaluated several technologies for the removal of H2S, which was estimated to be as high as 5000 ppmv, with up to 2-3 ...

  • Monitoring System for Hydrologic Evaluation of Landfill Covers

    Three test sections were constructed and instrumented to assess the hydrologic behavior of earthen final covers at two municipal solid waste landfills. A traditional design using a “resistive barrier” was used for two of the test sections, whereas an alternative design using a “capillary barrier” was used for the third test section. The test sections were built in two distinctly different ...

  • Dynatec Provides MBR System for Hazardous Landfill

    The Problem A hazardous waste landfill in Belleville, MI, owned by the Environmental Quality Company had a problem. They needed to develop a treatment process to remove COD, high TDS, heavy metals, phenol, PCB’s, Ammonia, and Molybdenum from the landfill leachate. Current treatment comprised of chlorination and activated carbon treatment was very costly. ...

  • Oxidation System for Sanitary Landfills & Recycling Centers

    The Broward County, Florida, Central Sanitary Landfill & Recycling Center operates the country’s largest landfill gas turbine-to-energy plant. Approximately 9 MMSCFD of landfill gas is collected from 300 wells and converted into electricity. During the cleanup after hurricane Andrew, large amounts of construction and demolition debris were brought into the landfill for disposal. Over a very short ...

  • An expert system on site selection of sanitary landfill

    It is desirable to encapsulate heuristic and empirical knowledge including hydrological and bio-geochemical considerations into the selection process of a potential landfill site. This paper delineates a prototype expert system, which has been developed using a commercially available microcomputer-based expert system shell VISUAL RULE STUDIO, for the selection of a landfill site. VISUAL RULE ...

  • 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 ...

  • 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 ...

  • Landfill slope stability

    Birdsall Engineering, Inc. has recently undertaken a landfill slope stability project using SVDynamic. This project dealt with a difficult and unconventional problem that SVDynamic was able to solve quickly and easily. The below quote further details this modeling project: "In order to optimize airvolume at an existing landfill we had to evaluate the slope stability of the piggy-backed waste body ...

  • Synthetic turf system solves landfill erosion challenge

    After four years as landfill district manager for IESI Corp., Delaney Lewis was discouraged. Although one of the Louisiana landfills for which he was responsible exhibited ideal geology, the soil characteristics were not conducive to side slope maintenance. The soil of the LaSalle/Grant landfill was highly erodible, exhibited a high plasticity index and had a natural pH of 4.0. ...

  • Wind-driven SVE system extracts VOCs from landfill

    An innovative soil vapor extraction (SVE) system has operated at the former Ferdula Landfill site in Frankfort, NY, for the past 10 years. The system relies on wind-driven vacuum processes rather than electrically powered air blowers to extract volatile organic compounds (VOCs) from the landfill. After a two-year trial beginning in 1998, the New York State Department of Environmental Conservation ...

  • Recycling Systems, Inc.: diverting waste material from landfills

    By recovering materials at its own facility and reducing waste travel to landfills, RSI is competitive in a marketplace of giants while providing a platform for sustainability and environmental stewardship. With the rollup of many independent waste haulers in the late 1990s, many construction companies found themselves with few service vendor choices. The family owners ...

  • Application of a Wireless Remote Monitoring System on a Landfill Flare Station

    ABSTRACT The Seminole Road Landfill flare station in DeKalb County, Georgia was previously equipped with an automatic telephone dialer system that contacted the operators of the flare via telephone when the flare station shut down and there were frequent flare station shut downs. During flare station shut downs all repairs required labor intensive response to physically visit the facility to ...

  • Membrane Bioreactor for Sanitary Landfill

    The Problem The county of Warren NJ owns and operates a sanitary landfill in Oxford Twp, NJ. The facility generates an average of 50,000 gallons per day of leachate, with peaks to 100,000 gallons per day. The facility was discharging to a local POTW from their lagoon, but they were facing requirements for nitrogen removal from the POTW and needed a new system to provide ...

  • 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 ...
