Definitions
- the invention relates to a method for depositing shredder waste on a landfill and a landfill created by the method.
- Shredder waste in the Waste Catalog ⁇ -Norm S2100 is understood to mean a precisely defined type of shredded waste, consisting among other things of the processing of end-of-life vehicles, scrap and bulky waste. This type of waste is also known as shredder light fraction and fluff, in Switzerland also known as resh. The crushing is usually done in hammer mills.
- the shredder waste Due to the raw material, the shredder waste has a high specific calorific value, on the order of lignite. Disposing of such waste is therefore not without problems because of the risk of spontaneous combustion.
- shredder waste is difficult to incinerate in waste incineration plants in an economical manner, since on the one hand the high proportion of metals and plastics has a disruptive effect and on the other hand in the course of the necessary, elaborate, multi-stage flue gas cleaning residues (water-soluble halides, mercury and cadmium compounds) arise which are more difficult to deposit than the original shredder waste.
- shredder waste When recovering metals, for example in a blast furnace or by means of blast furnace-like processes, shredder waste cannot be used favorably because of the substances it contains, in particular tin and copper, since these significantly reduce the quality of the iron produced, while at the same time reducing the quality of the shredder waste contained non-metallic components high emissions of air pollutants, as stated above, cause what is unsustainable for ecological reasons.
- the invention now proposes a method for landfilling, in which the disadvantages mentioned do not occur and in which, surprisingly, substantial advantages are achieved in the operation of the landfill in the areas of odor control and seepage water.
- the shredder waste in layers to the other waste stored in the landfill, to the shredder waste layer again a layer of the other waste to be disposed of, again to a layer of shredder waste and so on.
- the invention also relates to a landfill for shredder waste and other waste, in particular residual waste, and is characterized in that the shredder waste is present in layers in the landfill and that the individual layers of shredder waste are separated from one another by layers of other waste, preferably the Layers of shredder waste have a thickness of 10 to 120 cm, preferably 20 to 40 cm.
- the shredder waste is preferably applied at the end of a working day, because of its composition it brings about a noticeable reduction in the odor-laden gaseous emissions of the other waste and, moreover, because of its consistency, it is able to remove large amounts of moisture from rain or snow and of course also to take up the dew falling at night, to store it in the layer, thus close to the surface of the landfill, and to evaporate the moisture again the next day or after the end of the precipitation, as a result of which a significant reduction in the amount of leachate from the landfill can be achieved.
- the layers of residual waste and shredder waste lying one above the other in the manner of a dobo cake bring about a substantial homogenization of the seepage water accumulation in the drainage system of the landfill, which is favorable for the operation of the landfill and enables the high storage capacity of the shredder waste in combination with its layered application, which prevents the liquid resulting from precipitation from rapidly breaking through, so that seepage water can be sprayed onto the topmost layer of shredder waste, from where it is due to the heat of the landfill (in principle, these are reactor landfills) ) evaporates to a large extent and only seeps through the landfill to a small extent and accumulates again as leachate.
- the bottom waste layer of the landfill consists of shredder waste, since this pre-cleans the accumulated leachate and promotes a reduction in the leachate to be disposed of.
- the intermediate layer of shredder waste applied according to the invention has a thickness of 10 to 120 cm, preferably 20 to 40 cm, measured after the application and compression, but is applied before the application of further layers, the lower limit being determined by the ability of Layer for binding odors and absorbing moisture, the upper limit is determined by the risk of spontaneous combustion.
- the optimum layer thickness to be aimed at therefore also depends on nature of the underlying landfill material (odor development), of course also depending on whether the shredder waste to be applied has a rather high or low proportion of foams and the like. Fractions with a large specific surface has or not, and finally even from the expected moisture input.
- the odor-binding effect of the layer of shredder waste according to the invention is based, as mentioned, on its adsorptive properties and on the fact that at least about 40%, but in most cases 50% and more, of the resulting gases due to the instantaneous (loading area " which has not yet had a final top landfill cover (with a gas vent, etc.) in place.
- This area of the landfill also contains the fresh, most reactive garbage.
- shredder waste layer can be removed in the morning. If there is enough shredder waste, it is simply tipped over at the appropriate place in the landfill during the delivery and, after the end of the daily delivery and landfilling, the other waste is pulled over it and compacted and smoothed using the usual methods.
- the effects which can be achieved according to the invention are essentially based on the proportion of Shredder waste, which has a large relative surface, for example foam rubber and the like. Material from car seats and bulky waste, but due to its production, mostly in chamber mills, the shredder waste also has an additional high proportion of fine material, which has a large specific surface.
- the landfill according to the invention makes it possible to add or add additives, such as coke powder, lime or the like, to the layer of shredder waste at precisely definable locations and thus in precisely definable areas of the landfill. added since such additives can be kept in the shredder waste layer and can thus be fixed in the landfill.
- additives such as coke powder, lime or the like
