  • How Tire Shredding Protects Wildlife

    One of the most revolutionary inventions in the history of mankind was the wheel, and the best upgrade to that invention was the rubber tire, which overcame the limitations of wooden or metal wheels and made it possible to have smooth rides at fast speeds. However, there is a significant drawback to using rubber tires: eventually, they get too worn out to be useful as tires anymore and have to ...

  • `Standards are desperately needed for plastic and pesticide contamination in soil´

    In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

  • 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. ...

  • Inox in a landfill

    For collection and transport of leachate, landfill sites are using various types of pumps. Grindex electrical corrosion resistant pumps provide the volume needed where pneumatic pumps and other submersibles pumps fall short. One of the landfills in Illinois has 18 Grindex corrosion resistant pumps in operation and they now have plans to replace all remaining submersibles with Grindex INOX pumps. ...

  • Landfill clearance

    Selling 8,000 pieces of furniture each day means the folks at Raymour & Flanigan Furniture have to contend with packaging for 8,000 pieces of furniture each day. And that's a whole lot of cardboard, plastic and polystyrene. But the Liverpool, N.Y.-based retailer has been aggressively tackling its waste streams in recent years and just added a new program to handle the large amount of ...

  • 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 ...

  • 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 ...

  • Solar energy landfill caps

    Things weren’t going well at the Erewhon Landfill. It was time to close the facility, and there was no soil left onsite for construction of the cap. Erewhon was a County facility, and the money available for 30 years of post-closure gas monitoring, groundwater sampling and reporting, erosion repairs and maintenance of a grass cover was sorely needed elsewhere. The landfill manager recalled ...

  • 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 ...

  • 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 ...

  • The Behaviour of PVC in Landfill

    This study carries out an analysis of the behaviour of PVC waste in landfills. An estimation of the quantities of PVC waste landfilled annually is presented. The study provides a survey of existing literature on the behaviour of PVC in landfills, in particular the behaviour of additives present in PVC waste (heavy metals, phthalates). In addition, practical experiments have been carried out in ...

  • Non-recyclable but not ready for a landfill

    They say recycling is dead. In the current model with the economy as it is, I’d be inclined to agree. But it doesn’t have to be that way. When we as companies start focusing on how we can collaboratively increase our efficiency, decrease our workloads and create smarter customers, we all win. That’s what an upcycling-focused products company does—choosing a different route ...

  • Landfill leachate treatment

    BOYDEL is pleased to confirm that we have produced great results running a heavily fuel and metals laced municipal landfill leachate through our LMR electrocoagulation reactor. The attached picture essentially speaks for itself except that the clear BOYDEL treated effluent is free of fuel smell and that the sludge depicted on the right side of the picture has not been further dewatered and is ...

  • Landfill Cap Enhancements

    Introduction: The precipitation to the landfill cover is balanced by the combination of following effects: run-off, cumulating in soil, evapotranspiration, and percolation. For a given amount of precipitation, in order to reduce or eliminate percolation, the effects of run-off and/or evapotranspiration need to be enhanced. Water Harvesting Water harvesting uses ...

  • 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 ...

  • Keeping APCr out of Landfill

    The CIWM have recently featured an article by our very own Dr David Deegan in the latest edition of their magazine. The article explains why Tetronics International were unhappy to be informed recently that Defra ministers had taken the decision not to remove the ...

  • 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 ...
