Furthermore, the invention relates to products produced by the method, in particular landfill-compatible landfill cover stones, cable cover plates, drainage pipes, shaped stones and the like.

  • the resources are collected and certain materials are sorted and / or cleaned for further use.
  • the waste materials are roughly sorted according to materials, certain of the pre-sorted parts are shredded, the shredded parts are separated according to materials, parts of the same are washed and the washed parts are separated according to different materials. A portion of this is reused, while another portion is disposed of, incinerated, or landfilled depending on the type and degree of pollution, as well as on materials.
  • DE-PS 3248 493 C2 discloses a process for recovering valuable materials from mixed waste from the construction industry and a plant for carrying out the process. This process is also complex and requires high investment costs for a corresponding system.
  • the delivered mixed waste is sieved in front of an intermediate bunker and the sieving process is then continued, then the wood that is suitable for further processing is separated from the intermediately bunkered Sfebüberi before it is shredded, the shredded material is separated into a fine and coarse fraction after an iron separation, the sieving operation of this sieving together which also has an iron separation in a two - stage sieving into a fine -.

  • the hollow plastic body should advantageously be marked by an optically detectable code (DE - PS 35 20486).
  • the object of the invention is to provide a recycling method and a recycling system for plastic waste contained in household waste and / or special hospital waste, with which it is economically justifiable to produce products from the plastic waste obtained, which are particularly suitable for problem-free landfilling and can also be used in practice when building landfills.
  • the problem is solved with a recycling process for plastic waste contained in household waste and / or in special hospital waste with the invention in that in a delivery station from the household waste and / or from the special hospital waste an artificial fraction contained therein is sorted out, and a composite of different types of plastic is used as well Proportions of plastic mixed raw material containing adhering impurities are obtained and this is further processed in an unsorted manner for the production of products.
  • the measure proposed by the invention to mix portions of the most diverse plastics with adhering impurities to form a plastic mixed raw material and to process this batch unsorted to produce products obviously contradicts the previously established opinion of the professional world that only type-sorted sorted plastic parts are recyclable. It is all the more surprising that the invention proposes a recycling process and a recycling system, with the aid of which the further processing of an unsorted plastic raw material is made possible. But it is precisely through this proposal, which contradicts a widespread experience of experts in the art, that the previously existing economic inhibition threshold for recycling plastic parts is surprisingly reduced and a particularly economically advantageous method is shown for processing such mixed raw material into usable end products.
  • the process is designed in this way. that a plastic fraction sorted out of special hospital waste is first pre-comminuted and disinfected in a comminution disinfection station and thereby processed into a household-like waste, but in a sterile form, and then added to the plastic raw material obtained from household waste.
  • the plastics fraction from the special hospital waste can be sorted out using mechanical means according to another proposal. This has the advantage that human workers do not come into contact with the special hospital waste.
  • a further embodiment provides that the plastic fraction from the household waste is read out by hand in a reading station.
  • One embodiment further provides that pre-comminuted plastic raw material obtained from domestic waste and / or special hospital waste is temporarily stored and delivered by one or more intermediate stores to a central thrower processing station and first comminuted therein in a fine comminution stage, batches of comminuted material being added to a silo and mixed therein and stored and then an extruder is used to produce a preferably strand-like intermediate extrusion product and this is cooled in one pass through a cooling calender, in the further pass through a diathermy station which preferably generates a high-frequency field, and then the extrusion strand is chopped into pellets, the pellets obtained are temporarily stored and removed the pellets are made into usable products in a final processing process.
  • the pre-comminuted plastic chips are comminuted in the fine comminution stage to an average particle size of less than 10 mm, preferably 4 to 6 mm.
  • the final processing method is an injection molding process. Such is particularly advantageous because the intended end products can be molded on in a named and economical manner.
  • the final processing method is an agglomeration and shaping method using a preferably hydraulic binder such as a cement / water mixture with or without blast furnace slag or a mortar which is water-insoluble after hardening.
  • a preferably hydraulic binder such as a cement / water mixture with or without blast furnace slag or a mortar which is water-insoluble after hardening.
  • shaped blocks can be produced from the pellets using economical economic means and using plant elements known per se.
  • a process step that can be integrated into the process sequence can be carried out according to a further proposal in such a way that after the first and / or after the second comminution stage, an intermediate screening is carried out, during which parts of fine substances, in particular adhering impurities or during the comminution, are released ⁇ set liquid and / or foreign substances are sieved from the plastic mixed raw material.
  • a recycling system for the production of products from plastic waste in particular for carrying out the method according to claims 1 to 10, provides system parts according to features a) to c) in claim 11. Further advantageous configurations are provided according to the features of claims 12 and 13.

  • the screw extruder 7 which is known per se, is equipped with special, highly wear-resistant and particularly strong internal parts and tools. Due to the fact that within the extruder the plastic is converted into a partly viscous state under heat and pressure and thus results in a kind of lubricating film, an extruder equipped with highly wear-resistant and particularly strong interior parts is able to work trouble-free with a long service life and corresponding availability . This is also a surprising, advantageous result of the invention for experts.
