landfill technology Applications

  • Landfill Leachate Treatment

    Effluents from waste (leachate) are highly polluted and must be treated efficiently before they can be discharged into a municipal sewage plant or a local watercourse. Conventional treatment technologies do not suffice. Chemical processes are not economic due to the high pH buffer capacity of the leachate. Hardness and chlorides in the leachate are a problem for many plant components. Besides, process knowhow and operating experience are indispensable for an effective elimination of the harmful ammonia nitrogen. Certain processes also produce residues such as concentrates, which must be removed from the landfill body. This disposal is very expensive. WEHRLE is a reliable and experienced plant constructor for those applications. The first leachate treatment plants were built in 1991 and have been in constant operation ever since. This is not only proof of excellent technology but also for sustainable efficiency with stable, predictable, low operation costs.

    Reliable Shredding Technology for Pulper Ropes

    In addition to a homogenised granulate of your residual products, our customized shredding systems guarantee an optimal pre-product for further recycling or thermal utilisation in your plants. Pulper ropes or the reject are secondary raw materials that are created when waste paper is recycled. The pulper ropes must not be landfilled due to their material composition and must therefore be recycled accordingly – in most cases through shredding and subsequent separation of metals, glass and stones, etc. Our rotary shears or 2-shaft shredders together with our 4-shaft technology are very well suited for this application case. The advantage of the 4-shaft machines lies in the fact that the pre- and re-shredding occurs in one process step.

    Evaporation technology for waste industry

    The leachate produced by the waste in the landfill is an extremely pollutant effluent that requires high effective treatment processes to comply with the very strict limits for discharging operations. EVALED evaporators are a technological solution which allow to exploit the biogas cogeneration for the full or partial power supply of the plant within the limits of the environmental regulations and to reduce the relevant costs for thermal energy and leachate disposal.

    Waste recovery for petrochemical wastes

    Traditionally, the Petrochemical Sector has operated with basic technological solutions, with ultimate reliance on High Temperature Incineration (HTI) and landfill in order to deal with their hazardous wastes. However, tightening regulation, increasing landfill costs and social responsibilities are driving companies to look at alternative methods of treatment of very challenging wastes, including the treatment of:

    Air pollution control for ventilation air methane industry

    Ventilation Air Methane (VAM) is a Greenhouse Gas (GHG) released by coal or mineral mining operations, it is also commonly known as Coal Mine Methane (CMM).  The air pollutants from this process have a global warming potential 21 times greater than carbon dioxide, which is another well known GHG.  As alternative energy technologies have developed, methane is increasingly used to generate electricity and heat.  Landfills and mines represent two of the most abundant sources, however reports indicate that more than 50% of all VAM is exhausted from mine ventilation systems and remains unutilized.

  • Shredders for Electric and Electronic Equipment (WEEE) and Refrigerators

    Electric and electronic waste (WEEE), are coming from technology products such as home appliances (washing machines, vacuum cleaners), computers and tools. An economy based on the consumption such as today, provides a continuous increase of WEEE, and determines an increasing risk of dropping out in the environment or in landfills, with the consequences of pollution of soil, air, water and health human repercussions. These products should be handled properly and used for the differential recovery of the materials they are made of, such as copper, iron, steel, aluminum, glass, silver, thus avoiding a waste of resources that can be reused to build new equipment in addition to the environmental sustainability.

  • Automotive Shredder Residue Drying

    Getting economic value from landfill waste like automotive shredder residue (ASR) is a big challenge that can have a big payoff. Vulcan® Systems Drying Technology is the key component of material preparation when separating ASR waste to reclaim energy and metals. Vulcan® ASR Dryer Systems are manufactured to suit each client’s individual project needs and custom-designed specifically to dry ASR, making the material easy to transport, separate, and handle. This drying system consists of a drum with a burner that is mounted to a combustion chamber. Shredder residue is fed into the rotary dryer. After passing through the system, the dried material is discharged to a transfer conveyor for further sorting and separation. The vapor from the process is pulled through a cyclone that is specifically designed to deal with the fine ASR dust, as well as a high-temperature baghouse that removes additional fine particulates from the vapor stream.
