1. i) sorting the waste to obtain a polyethylene fraction and/or a polypropylene fraction with a purity of at least 90%, preferably to obtain at least one LDPE fraction, a residual polyolefin fraction with a purity of at least 90%, a residual fraction and optionally a high-calorific fraction;

3. iii) feeding the residual polyolefin fraction to a pyrolysis unit in which the residual polyolefin fraction is converted into a pyrolysis oil or pyrolysis gas;
4. iv) optionally feeding the high-calorific fraction to a substitute fuel conditioning unit, in which the high-calorific fraction is conditioned to form a substitute fuel, preferably with a proportion of native carbon in the range of up to 20% by weight; and if necessary
5. v) forwarding the residual fractions to a suitable recycling,

residues separated from the polyethylene and/or polypropylene being fed to the pyrolysis unit in iii) and/or the refuse-derived fuel conditioning unit in iv) as part of the processing of the polyethylene fraction and/or polypropylene fraction in ii), and heavy oil occurring in the pyrolysis unit in iii) or Pyrolysis residues is optionally fed to the substitute fuel conditioning unit in iv).

In the context of the invention described here, an “integrated process” is a process in which all process steps are carried out at one location without intermediate products having to be transported over long distances (more than 2 km).

“Replacement fuel” means fuels used in place of primary fuels such as coal or petroleum.

"Polyethylene Fraction and/or Polypropylene Fraction" means separate fractions of polyethylene or polypropylene, each of which is formed to a major extent (e.g. at least 90% by weight) from the material referred to.

If a polyethylene fraction and a polypropylene fraction are processed in step ii), at least one of these fractions is subjected to further purification in this step and converted into granules. Both fractions can also be subjected to further purification and the respective granules can be converted. The same applies to the methods and devices or plant parts described below if it is specified there that "the fraction is subjected to further purification and converted into granules" or the device is designed accordingly.

As part of the sorting, the material flow from post-consumer plastic packaging waste introduced into the process is divided into at least three main parts, of which the first (the polyethylene fraction and/or polypropylene fraction) undergoes mechanical recycling, the second (the polyolefin fraction) chemical recycling and the third (the residual fraction) is sent to suitable recycling. A fourth material flow that may be generated (a high-calorific fraction) can be processed for energetic use.

If a polyethylene fraction is produced in step i), it is preferably a fraction that consists of at least 90% by weight of LDPE. Alternatively or additionally, a polypropylene fraction is produced as part of the process, preferably with a purity of at least 90%. Other fractions that can optionally be generated in this step are, for example, LLDPE fractions or HDPE fractions. If such fractions or a polyethylene or polypropylene fraction are not produced in the process according to the invention, constituents from these materials contained in the starting material are assigned to the residual polyolefin fraction.

If in the process according to the invention, in addition to a polyethylene fraction, a polypro generated pylene fraction, this is preferably fed to a subsequent compression. The pressed polypropylene can then be sent to a treatment that does not have to take place within the integrated process. Alternatively, if the polypropylene fraction is further processed as part of the integrated process, the polyethylene fraction can also be processed, which does not have to take place within the integrated process.

The polyethylene and/or polypropylene fraction generated in step i), which preferably comprises a fraction consisting of at least 90% by weight of LDPE, can be white, transparent, mixed residual colors (i.e. without transparent and white parts) or otherwise "pure in colour". be (e.g. yellow or blue, preferably with a proportion of at least 90% by weight and in particular at least 95% by weight of components of the respective color), in which context a material is also considered "white" if it is formed from a mixture of white and transparent components.

In addition, as part of the sorting in i), a white, transparent, mixed residual color or otherwise pure polyethylene fraction can also be produced in the method, which consists of at least 95% by weight and preferably at least 99% by weight of polyethylene, which clearly comes from food packaging .

• Höchste erzielbare Qualität des mechanischen Recyclings, die sich insbesondere durch eine Vorsortierung nach Kunststoffart und Farbe und/oder durch eine zwischenzeitliche Reinigung der Fraktion mittels Heißwäsche realisieren lässt.

Thanks to the integrated process, parts that cannot be processed into the desired product in the respective recycling step can be transferred to one of the parallel recycling steps in which they can be used. In addition, heat that occurs, for example, as waste heat in chemical recycling in iii) can be used for process and/or cleaning steps in mechanical recycling, or for process steps in the context of conditioning the residue fraction into a fuel. This significantly improves the efficiency of the process, since by-products from one of the recycling steps (e.g. mechanical recycling) do not have to be transported over long distances to a plant in which another recycling step (e.g. chemical recycling) is carried out. Accordingly, the following advantages are realized:

• The highest achievable quality of mechanical recycling, which can be achieved in particular by pre-sorting by type of plastic and color and/or by interim cleaning of the fraction using hot washing.

When sorting flexible packaging, PP plastics (= polypropylene) that are very easy to recycle are often included in these flows. Depending on the packaging, the sorting criterion for PP is often critical. For example, many bowls or flattened cups end up in the flexible material flows. The optional sorting out of PP plastics takes this point into account. These are sorted out and are therefore not lost in mechanical recycling.

Maximum exploitation of potential is achieved because only the plastics that can be mechanically recycled best are mechanically recycled. All polyolefins that do not meet this quality requirement, as well as by-products of mechanical recycling (e.g. filter residues from extrusion) are chemically recycled.

An optimal yield of industrial fuel is achieved since all remaining plastics, with the exception of halogenated plastics (eg PVC), are converted into an industrial fuel. Residual fractions from the pyrolysis (e.g. heavy oil) are also added to this fuel. Paper components contained (e.g. labels) as well as organic residues from the residual contents of the packaging are also fed into this fraction. As a result, a proportion of native carbon of up to 20% or more, which is CO ₂ -neutral, can be set in this fraction. “Native” as used herein means carbon derived from materials previously formed (or sequestered) by natural biological processes such that this carbon is not accounted for in the carbon _footprint of waste incineration for climate-relevant emissions. The proportion of native carbon is preferably at least 5% and in particular at least 10%.

In the context of the invention described here, “pyrolysis oil” designates thermal decomposition products of polyolefins, which are produced from these by heating to temperatures in the range from 300 to 700°C. The pyrolysis oils refer to that fraction of the process that can then be condensed, while on the one hand gaseous products that do not condense under the condensation conditions and residues that cannot be vaporized as part of the temperature treatment are separated. These residues form heavy oil that remains in the pyrolysis process. As a product of the depolymerization of polyolefins, pyrolysis oil contains unsaturated components, which in turn can be used for conversion to polymers.

In the context of the application described here, a “pyrolysis gas” is a gas that is formed when the residual polyolefin fraction is heated in the absence of oxygen or under controlled “low-oxygen” combustion conditions. at In the absence of oxygen, monomeric or oligomeric olefins can be formed from polyolefins by thermally induced bond cleavages, which can be converted back into polyolefins after processing. In this way, new polyolefins can be formed which have almost the same properties as the starting polyolefins. Alternatively, synthesis gas (a mixture of carbon monoxide and water) can be generated from the polyolefins by controlled combustion with oxygen deficiency, from which hydrogen can be generated under suitable conditions via the equilibrium reaction CO+H ₂ O → CO ₂ +H ₂ .

As mentioned above, in the integrated process, waste heat from pyrolysis can be used for other recycling or recovery conditioning steps. In a preferred embodiment, waste heat from the pyrolysis unit is therefore used to heat process streams in the purification or conversion of the polyethylene and/or polypropylene fraction into polyethylene and/or polypropylene granules in ii) and/or in the conditioning for the production of a substitute fuel in iv ) used. In the purification/reaction in ii), the waste heat can be used, for example, for heating the washing fluid in a hot wash or for drying before extrusion. As part of the conditioning to produce a substitute fuel, the waste heat can be used, for example, to dry the fuel, e.g. the sludge.

Furthermore, in the integrated process according to the invention, exhaust air from the mechanical treatment can be used as supply air for gas burners for heating the pyrolysis, or residues from the mechanical recycling and the pyrolysis can be used for the production of high-quality substitute fuels.

Different pre-sorted fractions of flexible post-consumer plastic packaging waste can be used as the starting material for the process according to the invention, e.g. foils (DSD 310 or similar), PO-Flex (DSD 323-2, or similar), or mixed plastics (DSD 350/352, or similar). The process is aimed in particular at fractions with a polyolefin content of at least 50% and at fractions in which the proportion of flexible packaging (2D) is at least 50%.

In the context of the invention described here, the term "flexible" is to be understood as meaning that the materials can be easily bent by a user and have a thickness at which this is possible. Foils are an example of flexible packaging.

The sorting in step i) is expediently carried out by opening bales of post-consumer plastic packaging waste by means of a pre-shredder and feeding them to further pre-sorting. The material is classified and optionally separated by density, freed from ferrous and non-ferrous metals (which are assigned to the residual fraction and recycled separately) and fed to a multi-stage near-infrared and color sorter. The pre-sorting sorts the material into different fractions as required. For example, transparent LDPE films and/or polypropylene or other polyolefin polymers are sorted out for mechanical recycling in ii). The remaining polyolefins are assigned to a fraction for chemical recycling in iii) and the remaining plastic packaging, which remains as a residue from pre-sorting for mechanical and chemical recycling, is optionally sent to a production of high-quality refuse-derived fuels in iv). The material is then re-shredded to 20-30 mm.

The mechanical processing of the polyethylene and/or polypropylene fraction in ii) is expediently carried out by subjecting the respective fraction or fractions to a cold wash (=washing without temperature input, usually at ambient temperature), optionally additionally to a hot wash (=washing at a temperature of at least 60°C, preferably with an alkaline washing medium), an extrusion and optionally a subsequent decontamination (= temperature treatment at 50 to 155°C in a vacuum or gas stream). For details on such processing, reference is made here to the WO 2018/046578 referenced, which describes the relevant steps in detail.

In a preferred embodiment, the polyethylene fraction obtained in the sorting step and used as starting material for processing in ii) consists of at least 92% by weight, in particular at least 95% by weight and more preferably at least 98% by weight made of LDPE, preferably white, transparent, mixed residual color or otherwise color-pure LDPE. It is also preferred if the polypropylene fraction generated in the sorting step i), which is used as the starting material for processing in ii), contains at least 92% by weight, in particular at least 95% by weight and more preferably at least 98% by weight. -% Polypropylene, preferably white, transparent, mixed residual color or otherwise color-pure polypropylene. Alternatively or additionally, it is preferred if the residual polyolefin fraction for processing in iii) consists of at least 92% by weight, in particular at least 95% by weight and more preferably at least 98% by weight of polyolefin.

It is generally preferred if the polymer fraction obtained in the sorting step and used as starting material for processing in ii) is at least 92% by weight, in particular at least 95% by weight and more preferably at least 98% by weight. % consists of this polymer, preferably white, transparent, mixed residual color or otherwise color-pure polymer.

In a preferred embodiment, a waste stream generated as part of a cold and/or hot wash is fed to the refuse-derived fuel conditioning unit. Such a waste stream mainly contains material different from the main fraction of the process step, e.g. paper from labels.

As an alternative or in addition to this, filter residues occurring during the extrusion and/or the decontamination of the mechanical recycling are fed to the pyrolysis unit.

As an alternative or in addition to this, halogenated plastics are separated from the residue fraction during sorting before it is fed to the RDF conditioning unit. For example, near-infrared devices can be used to carry out automatic picking, in which PVC is separated from the material flow to reduce the chlorine content.
