METHOD OF PROCESSING WASTE BY SEPARATING ALYuMINIZIROVANNYKh AND PLASTIC COMPONENTS CARDBOARD OR OTHER PACKING, AND NECESSARY EQUIPMENT

[01] There is in this type of process patented processing and utilization of waste, in particular plastic, aluminum, cardboard or other packing, by means of method and equipment for extraction and separation of main components, present in package, for utilization of waste and prevention of environment pollution, which allows reuse of composite components are waste:

plastic, aluminum and paper in its initial shape, as a result of polymer can be different quality, allows insulated aluminum by melting and cleaning a conventional way, T. E. collection of aluminum cans and other pieces of aluminum, or, alternatively, this scrap can be used as raw material for preparing derivatives of aluminum, such as salts, aluminum organic or even of aluminum pigment, can be bring on market easily available and cheaper solvent, at low power consumption from cellulose may be again to perform cardboard for manufacturing boxes, and its even can be Now on subsequent clarifying, - processing of waste of investment in the process small raw material, and also we obtained the best ratio of price/quality.

[02] For this purpose should be have idea about technical facilities, used in processing industry for utilization of waste of, in particular, packing. Technology, used in the present time, is reduced cellulose from cardboard boxes, plastic and aluminium packing, which is intended for manufacturing paper. That relates to the use of other parts of package, then aluminum/polymer simply - simply ground and by means of pressure die casting is part articles, such as extruded filaments in brushes for sweeping floor, hot pressing is used in production of corrugated sheets, and many other articles. So, non-insulated aluminum is not used as expensive raw material component. Are known also processes processing, which are used pyrolysis for further generation of electric power, and then at the outlet that the liquid and/or gaseous fuel. Nevertheless, for this process, which produces fuel, much energy, energy is provided due to burning of part waste themselves, as in pyrolysis process is quite strong heat-absorbing reaction.

[03] Speaking about package, is important note, itself on art this "sandwich" from paper/aluminum/polymer, in which polymer component has the softening temperature in 125 theoretically and temperature of yield point in 190 theoretically, and consists almost completely from polymer, which contains kompatibilizator, which facilitates better lime low-density polyethylene with aluminium. For this function usually are used functionalised polyolefins, such as copolymer of ethylene and acrylic or methacrylic acid. These compounds, in its turn, facilitate improved compatibility of material, extracted from other thermoplastic materials, such as polypropylene and polyethylene terephthalate (PET), as well as polyamides, such as nylon®, thus thereby rendering more flexible future repeated field reconstituted material.

[04] According to requests made national and international patent databases, have been detected the following opening:

[05] Spanish-type Ukrainian P1 2383208 "procedure for processing materials, containing aluminum compound", discloses a method for, which restores cellulose by mechanical separation of packages and waste, and, respectively, leads to restoration of aluminum.

[06] In this process is destroyed polyethylene, it turns into paraffin and gases. For this operation is used plasma, which, in addition, which leads to destruction of polymer, but more and requires for its functioning of large amount of energy, as for operation with plasma practiced high temperature order 15,000 theoretically, and also necessity of operate in inertizirovannoi atmosphere, that means high cost.

[07] Some patents is used solvents for restoration of plastic from cardboard boxes: Brazilian Ukrainian P1 0202303 - 2 "method of separating much layer films, intended for packaging" uses different solvents, among which tetrahydro furan, xylene, toluene, carbon tetrachloride, organic acids, water, acetone and chloroform; Chinese Ukrainian the CN 1554691 "method of separating sheet aluminium and plastic in film, remaining from plastic packaging, containing aluminum" uses solvents, such as tetrahydro furan, tetralin, apart from addition of glacial acetic acid - component, which converts aluminum in salt;

and Korean Ukrainian 200100163 krone 52 discloses a process, which promotes reaction in the presence of alcohols, such as methanol, ethanol, propanol or butanol, with salts in the form of chlorides, such as mercury chloride, calcium, aluminum, magnesium, potassium or even of hydrochloric acid.

[08] In these processes are used in mainly high toxic and carcinogenic solvents and reagents, in addition, that they are large potential in degradation of polymer, connected or not connected with it, they react with aluminum, it into salt, which leads not only to the greater consumption of reagents, but also this prevents complete reduction of aluminum in its initial form of metal.

[09] Other patents is opened other methods for separation, for example, Brazilian Ukrainian pi0006641-and-9 "surface - active solution, used in the process of processing plastics for cleaning and separation of aluminum", in which the surface - active substance and formic acid for removing polymer film, operating in the range from 85 theoretically to 198 theoretically. Nevertheless, presence of acid at conditions, described above, leads to partial consumption aluminum, present in waste.

[010] Other patents also is opened processes, recovered aluminum by means of chemical reaction, usually using base or strongly acting acid:

[011] Brazilian Ukrainian P1 0706115 - 3 "processing of much sloinoi packing" uses solution hydro ksida sodium the same way, and as American Ukrainian the US 5127958 "cleaning of metal surfaces polymeric substrates".

[012] Chinese Ukrainian the CN 102532592 "substance, separating aluminum from plastic, and corresponding method of preparing", in its turn, uses from 5 to 50% acid with unauthenticated organic solvent in an amount of from 25 to 50%. The same way, Japanese Ukrainian Jp of 20040327047 discloses a separation of polymers by difference densities in glycol solution, and also attack aluminum with solution of hydro ksida sodium.

[013] Should be noted, that in processes, in which are used acid or base, these reagents are spent in sufficient amount, which increases cost of process, but also in case of complete or partial consumption aluminum there is economic loss, which is created as a result of product more with low cost.

[014] American Ukrainian the US 7.598, 297, to cover the other possible processes, fully describes the whole possible range solvents, and also and strong base, such as hydro ksid sodium or lead. The same way and at wide range of temperatures. Nevertheless, it insists on using only only xylene, which operates at various temperatures so, which can be selectively remove different polymers, which run in specified type of packing, however, field of strong base leads, undoubtedly, consumption to aluminum.

[015] European Ukrainian EP 0568791 discloses a card with respect to any solvent, absolutely of different nature, for example, derivatives of oil (aliphatic, aromatic, naphthenic), halogenated compounds and their mixtures, and also uses wide interval of temperatures from 40 to 500 theoretically, trying to produce exclusive rights on any of processes. However during separation process components packing, using package in its composite form of - paper, aluminum and polymer, - end, apart from wide range it results in high consumption solvent in the process. At specified method is also used, apart from other forms of application, supply solution, containing different dissolved in solvents polymers, to the process thermal cracking, operating in the range of 650 - 1200 theoretically and pressure from 0.1 to 0, 3 MPa.

[016] Processes, of said, have the following technical problem, which were solved by means of method, of used in the present time:

[017] 1. Some present-day processes is not reduced all components are in their more expensive state. Method, used in the present time, extracts all components are with quality, suitable for repeated use;

[018] 2. Some processes consume much energy at melting mixture of aluminum and polymer, also making polymer biodegrade. Method, used in the present time, performs separation only with solvent;

[019] 3. Some processes require complex and expensive operation separation of aluminum from polymer. Method, used in the present time, performs separation only with solvent by operations, which imply low level of investment and low cost raw material; and

[020] 4. Some processes is used toxic solvents, which heavily used in separation and processing. Method, used in the present time, uses inexpensive solvents, which in excess run on market, nontoxic, with the possibility of complete processing and low energy consumption.

[021] Processes, discussed previously, have the following discomfort, disadvantages and limitation of:

[022] and) some present-day processes is not reduced all components are to high level of their cost;

[023] b) during some modern processes of restoring polymer, isolated from aluminum, is involvement in the process other substances, which, in addition, that released not help recovery, but is this product low commercial value;

[024] in) during some processes is not separation of aluminum from polymer, both component are mixed, the aluminum, as expensive component in isolated position, enters products, obtained from said mixture only as filler;

[025] d) certain methods is isolated aluminum, but so make its consumed large amount of energy when using very high temperaturuslovie, which results to crack formation in polymer, which is destroyed and is obtained mixture wax and volatile compounds is less than total cost polymer, and also is required of operation conducting in an inert atmosphere, that, certainly, promotes to increase the agreed to cost;

[026]E) field expensive and toxic solvents;

[027] solid) high cost investment and processing; and

[028] 3) high ratio of price/quality.

[029] "Processing waste by separation of alyuminizirovannykh and plastic components cardboard or other packing, and necessary equipment" was developed for, to liquidate all discomfort, disadvantages and limitation of today's processes by means of method, based on use of special solvent, to dilute the polymer at the moment of extraction and separation of main components, for repeated use waste, preventing pollution of environment, for processing of the components waste, and recovery of composite parts in their initial shape for repeated use as plastic, aluminum and paper.

[030] Method according to the present invention has the following advantages as compared with existing methods:

[031] and) using developed process obtained polymer with quality, suitable for repeated use, for manufacturing articles and films, which can be made by means of the reconstituted product and, consequently, it can be used in such, in which it is isolated, or be mixed with other pure or learned polymer, in composition of mixtures, in which may be fillers, dyes or other additives;

[032] b) insulated aluminum can be the howl;it is treated in the process of melting and cleaning, as in traditional methods of processing of aluminum cans and other Lome of this metal and, so, can be used as raw material for production of alloys, blades, inorganic compounds, such as salts of, aluminates, or even organic derivatives of, such as alkylaluminum;

[033] in) invention uses solvent, which easily find on the market behind small price, as it is not result of synthesis, and only distilled oil fraction;

[034] g) as solvent, which is oil fraction, is used in a small range of boiling point, and it can not become one integral with product at the end of process, reduction of product becomes full after, as it in full is returned to the beginning of process. For distillation can be used simple equipment, without the need to carry out the fractional distillation;

[035] d) characteristics of solvent: low temperature boiling, low specific heat capacity seem especially important in connection with energy consumption, so, as soon as a small its part is subjected to evaporation, and almost the whole solvent processed without passing through distillation, and it considerably reduces consumption of energy, so as it occurs by filtering;

[036]E) method, used according to the present invention, restores polymer, retains physical and chemical characteristics, including kompatibilizator, which facilitates future use of polymeric waste, reduced in mixture with other termoplastmassami;

[037] solid) cellulose can be recycled used in production of cardboard, for manufacturing boxes, may also be used in the process of clarification;

[038] h of) less expenses on investment and processing; and

[039] 1) low ratio of price/quality.

[040] The present method was is based on knowledge and experiment inventor in its technical scientific - research operation and previous-working about blocks, consisting of paraffin and polymer, used as barrier against radiation, and then the development of explosive compositions, in particular of the emulsion type.

[041] Began investigating, to meet demand for waste processing packing for reduction of polymer/aluminum, contained in waste and produced as a result of mechanical process, which uses hydrapulper for restoration of cellulose from aluminized packing.

[042] Was to initial removal of aluminum by dissolving, etching for production of aluminium salts, designed for use in purification of sewage water. Process was also adjusted, to produce aluminates, sulfates and aluminum chloride. Polymer obtained, after its the boiling out with acid or base, and then after washing went further processing. Nevertheless, cost evaluation of such salts, aluminum, and by comparing the flexibility in use of aluminum in its metal state (reduced), was classified to estimate possibility of its removal from metal without its oxidation.

[043] Based on knowledge properties of polymer, with respect to their structure and the convergence with solid paraffins began testing solubility of polymer in solid paraffin in the following sequence:

[044] In beaker, containing 100 g of solid paraffin, exposing its melting and increasing temperature to 100 theoretically, added 20 g film, containing aluminium/polymer. Temperature differenceto approximately up to 125 theoretically. Glass stirring bacillus for five minutes. Then perelili content beakers in other, paraffin by passing through metal sieve. After cooling content sieve washed cold by the tetrachloromethane. Knowing, that cold carbon tetrachloride dissolves paraffin, but polymer dissolved only at heating, can be see, that paraffin deleted polymer, cohered with aluminium. This can be verified, if of breaking the obtained film, which it was broken, not being extended, unlike plastic film, which it vomits podrugomu.

[045] Other lead consists in the fact, that mixture of paraffin/polymer hardened at lower temperature at heating, as compared with test only with with paraffin.

[046] Taking into account this, steel think above possible by paraffin separation from polymer. Faced with problem, which present difficult-to-solve, as is impossible was think about distillation or fractional solubilization, therefore that mixture occurred high molecular mass. The following pitch - direct field carbon tetrachloride. However due to high cost, and its high toxicity of, refused from its use.

[047] Then investigated other chlorides, however happen again the same construction of the problem.

[048] The following stage was - it possible to study aromatic solvents, chlorinated and not chlorinated, naphthenic, and also alcohol esters, amyl -, methyl -, butyl acetates and T. U.

[049] In parallel also was reconstructive removal of aluminum, cohered with the polypropylene, PET and PVC, present in various packages, such as blisters tablets, packing for powders - future beverages, packing for biscuits, sweets and chips. For all data products obtained positive results, connected with some germs solvents. Some solvents have been studied are more thoroughly, taking into account question health risk, availability and their cost.

[050] But main object has been cardboard alyuminizirovannaya package. In connection with this, tests with other wastes were suspended, leaving kind of package in priority and continuing testing.

[051] In connection with difficulties of isolating paraffin during use, decided above consider use of kerosene, as its structure similar on structure of solid paraffin. Obtained results are with the use of similar mass, have been positive. Dissolving happened less than 5 minutes. But appears one more problem - as removal of solvent from polymer. Solvent should, is possibly, have in its composition paraffin compounds high molecular mass in small amounts, and for this purpose it is necessary to brought polymer to more high temperature for effective removing residues of component. In addition, taking into account size chain of kerosene and paraffin, interaction would quite strong, and said factor prevents separation.

[052] The following pitch was then separation by precipitation. Polymer solution/kerosene after cooling was is presented in form of mass. This mass then in brought in equal volume in ethanol, mixing components. Then precipitated polymer is filtered, subjecting its successive washing with ethanol. Then it is subjected to drying and in result is obtained precipitated polymer.

[053] Mixture solvent is subjected to distillation, to separate kerosene from ethanol. Taking into account difficulties separation of residual kerosene from precipitated polymer by distillation, used solvent with identical characteristics kerosene, but with lesser boiling point.

[054] Has been used hexane from - behind the, that it is more volatile solvent, dissolving conducted in flask, which wore to return a refrigerator. Was used similar ratio of solvent/precipitate. Through five minutes dissolution has occurred.

[055] In another experiment has been used petroleum ether, distillation range from 60 theoretically. The postoperative period difficulties dissolving, as unlike hexane, used in given above testing, in this experiment temperature reaches the insufficient for dissolving level.

[056] In the subsequent experiment, if its compare with previous one experiences, reburied equal number of solvent/waste in the steel reservoir, which is then closed and placed in the hot water for heating. When water bath reaches the boiling point, reservoir, which subjected heating, withdrawn and left cooled. At opening of tank, as its content more left slightly hot, most of the solvent evaporates from reservoir, and as a result polymer sponge. Then for experiment conducted under pressure, to take softening temperature polymer. Dissolution has occurred, solvent is removed gradually, preserving the dissolving tank heated, at the same pressure and temperature, and to produce, at the end of ends, after cooling, solid polymer.

[057] So, after carrying out various experiments was is made conclusion, that the most suitable solvent for separation and isolation of polymer from alyuminizirovannykh plastic and cardboard boxes, is alkane with low and middle boiling temperature, and consequently, with more low molecular weight, therefore that it flying interacts with large polymer chain, and due to reduced length circuit provides rapid interaction and subsequent dissolution of polymer, and from - due to the short chain length solvent easily penetrates between links polymer. Also linear structure similar solvent with structure of polymer, and therefore does not effect on it, so, takes place only rupture forces van - der - Waals.

[058] Reason, which was classified to use normal paraffin hydrocarbons (alkanes with straight chains) - therefore that they are less than toxic compounds, aromatic than or even naphthenic, minimizing also marks decay polymer (from - the structural similarity), and also from - by their lung elimination of by evaporation and/or distillation).

[059] Experiments show possibility to use solvent paraffin hydrocarbons at boiling temperature below 120 theoretically, preferably from 60 to 100 theoretically, process passes considerably lower than the melting temperature of polymer, which is about 190 theoretically, and so, it should be mentioned, process is at temperature below softening temperature, about 105 theoretically, but operation of such high pressure is optional. Easily st dissolution and subsequent flexibility in its extraction, when returning to atmospheric pressure leads to better quality reconstituted polymer. To circumvent the problem the temperature of dissolution, if it will be below temperature of polymer softening, can be increased pressure, and then will be ideal softening temperature is for the process of.

[060] That make separation of solvent, as boiling temperature lower than temperature of polymer softening, solution when the desertion the dissolving tank, part is solvent it evaporated, at least before removing aluminum is added one more new solvent (distilled), which otmyval aluminum. All this prodelyvalos, end same, after removal of solution, containing major part of polymer. This solvent, more in heated state, used as the first solvent for the next portion of, it also optimized process reducing solvent.

[061] Solution, containing polymer, after partial concentration from - the partial solvent evaporation, whose pair have been conducted through capacitor, gets the next stage.

[062] Finally, as the latter experiment evaluated method of filtration. Known, during ultrafiltration (emulsions, bacteria, fats and macromolecules), range of working pressure is from 1 to 10 bar, the membrane has pores from 0.001 to 0.1/"". So as average molecular mass of polymer~, 200000 Da of, this equipment could become much promising, for example, together with the possibility of! rational use of energy. Field boiler gases from chimney at temperature of about 250 theoretically, such gases, that should be their carried out in concentration tower or tape and to perform drying polymer. Nevertheless, if was is made fusion of aluminum, at cooling ingots air from heat exchanger jut beyond would with initial temperature of 650 theoretically and final temperature could would be approximately 125 theoretically, so, using energy appropriately.

[063] First tested filtration under pressure solution with the content of 11% polymer, dissolved by means of filtering paper and porous ceramic plate. Observed, solution migrated through pores, and more concentrated polymer simplified on paper.

[064] In other experimental medium is subjected to cooling at room temperature solution and subsequent its filtration through paper, of a light pressure hand on the equipment in the form of syringe, and observed, that solvent easily it was separated. Then wet scone, covered in paper, they pressed by means of press, and cake is became contain very small amount of solvent. So, to become obvious, that process of separation can be effectively improved, thereby saving energy, by filtration hot solution, and then subjecting scone compression on filtering surface. As is used filtering paper, then cake is from it is separated very easily, then it can be raskroshit and subjected final drying with full elimination of residual solvent, with or without preliminary washing.

[065] Also checked minimal time, required for dissolving polymer, film, cohered with the aluminum film in containers Tetra Packs®, for which wastes such packages with already removed cellulose have been subjected to dissolving in kerosene and seasoned at 100 theoretically. Using forceps, pieces of film size approximately 30 [mm30 X 30 [mm30 have been are immersed into solvent, podogrety and light motion had been removed through different time intervals: 2, 4, 6, 8, 10, and up to 20 seconds. Each separate a piece of, immediately after the, as its out of the from heated kerosene, plunged into the other bulb, containing cold petroleum ether. This washing procedure, that is, removal of a residual solvent, in which have been film, and also facilitating subsequent removal at low temperature. For checking effectiveness of the process of dissolving, each piece was subjected rupture. It should be mentioned, that film of aluminum/polymer, which should be subjected to this procedure, stretches, introducing a aluminum film with cracks, and all more glued to stretched polymer film. As a result drawn testing can be see, that even those pieces, which withstood in solvent only for two seconds, have shown, that removal of polymer it is possible, and this fact is confirmed its brittleness at rupture. Taking this fact into account, can be say, that time, required for solubilization of polymer, extremely reduced. It is connected with the big area of film, and with its reduced thickness. However, in order to ensure removal of the whole polymer, preferably equally material immersed in liquid st during more than long time, in particular, to provide more dissolving present thick layers, for example, in case of connecting seams boxes, where application of film. Is important also, to removed cover at the stage of dismantling boxes, as if they will be participate in stage dissolving, required is much more time for heating. Therefore, if not remove, if they will be together with aluminium, then they should be removed by the mechanical method from mixture of aluminum foil/polymer and covers, by means of sieve or grid. Shaking also has important value at diffusion solvent, and also facilitating non-waste, which, as a result of the above described process already they are rumpled and are assembled together.

[066] If briefly, then in new process are the following new function:

[067] 1. Dissolving polymer with use of solvent from family alkanes with middle and low boiling temperature, and so, more low molecular weight, preferably paraffin hydrocarbons with boiling temperature lower 100 theoretically, preferably from 60 to 120 theoretically. Illustrate this new the process can kerosene, but operates only at 105 theoretically, T. E. at temperature considerably below its boiling point, and considerably below its combustion temperature, T. E. low propensity at given temperature is the advantage. Further - in cold removal of residual kerosene by washing hydrocarbon with low boiling point, and it easily is eliminated finally. These hydrocarbons easily interact with large polymer chain, helping, from - the small size circuit, fast rate interaction and to the subsequent dissolving polymer, as from - behind its short chain length hydrocarbons easily penetrate inside and spread between polymer chain, and as they have similar structure, they almost do not have with respect to to rupture circuit, and takes place only rupture force van - der - Waals;

[068] 2. Process at temperatures considerably lower than the temperature of the polymer melt, which is approximately 190 theoretically, so shows, that it passes at temperature below softening temperature, which is about 125 theoretically, and operation under pressure is not necessity. This news also carries as advantage, speaking about the following operation, easy removal and further recovery of used solvent, during action on atmospheric pressure;

[069] 3. Separation of aluminum and polymer from waste, rich in polymer/aluminum by dissolving polymer in circulating solvent with polymer concentration in the solution in during the whole time of staying in it;

[070] 4. Separation of polymer and solvent from the solution, concentrated-rich polymer, to obtain at the outlet polymer for repeated use and reprocessed in the same process of solvent;

[071] 5. For elimination of solvent residue in solution aluminum is used solvent for washing, selected from hydrocarbons with low boiling point in preferable form hydrocarbon fraction in the range of distillation or hexane or petroleum ether, or, alternatively, ethanol 96 specific Gl.

[072] 6. Process requires reduced time dissolving and, consequently, can be operation continuously, which leads to reduction of dimensions of dissolverov and can be made either by means of screw conveyor or belt conveyor with by immersion into solvent, swinging pump, connected with filtration, with cooling or not, in case such ultrafiltration equipment, as extruder, in which wall is filtering element, or any structural arrangement in assembly, which is capable of perform single operation in continuous mode or even lengthy operation combination by parties;

[073] 7. Optimization of process relative to energy, if consider the whole chain of restoring, becomes separation of paper cellulose, aluminum and polymer, thus restoring heat between phases of process, use of gases, for example, boiler or smoke flue at temperature of about 250° with for drying tower or tape, for drying polymer after evaporation of solution for washing. In case of carrying out of aluminum melting, ingot cooling can be made in the chamber, where hot gases, engendered from - the cooling, returned would heat aluminum and could be used or for heating part of solvents or even for as a whole drying films, remaining after removal from cellulose, to beginning of process solubilization, drying of sprayed polymer after its removal from solvent, in which its washed. This actually feasible, since we would have of by hot gases with initial temperature of 650 theoretically, at the end of temperature can be approximately 105 theoretically;

[074] 8. Optionally separation of polymer solvent to by distillation, lots, addition of fresh solvent (distilled) before removing aluminum from the dissolving tank, washing aluminum, thus removing polymer residue aluminum, which prikrepilsya to it. Its subsequent field as the first solvent for the next portion of, not only provides effective field of solvent, and also leads to larger and more effective extraction of polymer;

[075] 9. Production of isolated polymer, without remelting, to avoid waste of time on melting process;

[076] 10. Alternative formation of polymer film, with parallel to regeneration of the solvent by means of process, performed in tower with shaft, heated steam, this film may be reduced immediately or not immediately after process its formation;

[077] 11. Alternative separation polymer, contained in solution for spraying preliminarily concentrated solution on rotary disk and chamber type spray-drying; and

[078] 12. Production of precipitated polymer by introduction of the second solvent.

[0291]E. SG with. Solvent is removed by means of direct heating water steam, engendered solvent vapors is directed to capacitor, and then in settler, that to carry out separation of supernatant phase and immiscible solvent;

[0292] E.C.l.d aqueous phase - this distillation for reconditioning in it of ethanol, dissolved in distiller, and organic phase, which contains more solvent for dissolving process, and all this passes to following distillation in the distiller, vosstanavlivayas from this mixture, solvent for dissolving, and also a small amount of ethanol, and distributes in balance with solvent for dissolving in phase equilibrium; and

[0293]E. SG E. Polymer obtained is filtered in the filter and dried in usual drier, and is obtained dried precipitated polymer.

[0294] In case of containers, containing only alyuminizirovannye polymer films, without paper and not containing polypropylene and polyethylene, should be the same procedures stage and with (after extraction cellulose), that is recovery of residual polymer/aluminum, similar to previous case, only difference in working temperature. If it developed till 100° with, then dissolved only polyethylene, and polypropylene remains not dissolved. In this condition hot solution is filtered and results with other solid substances of undissolved components, polypropylene and aluminum, after washing with petroleum ether, and then with ethanol, they re-dispersed in liquid STI by grinding on small pieces, in its genus blind a blender. Liquid st can be, for example, ethanol. In this condition, aluminum ground, leaving CS of larger size, so, allowing it easily separate by filtration through sieve.

[0295] The process can be additionally optimized with respect to energy, consider if the whole chain reduction, whether this separation of paper pulp, polymer and aluminum, reduction of heat on all stages of the process, for example, field boiler gases (in flue), output of~, 250 theoretically for drying tower or tape for polymer drying, after evaporation of the solvent for washing polymer. In case of the process of melting aluminum, ingot cooling can be made in the chamber, in which hot gases, resulting from cooling, reconstructed would heat aluminum, then it can be to transmit to or for heating part of solvents, or used for drying as a whole, for example, for films, resulting after removal of cellulose, before starting process of solubilization, drying polymer with sprayed on it composition, after removal of cleaning solvent. It is possible therefore, that in our disposal will be hot gases with initial temperature of 650 theoretically, at the end of temperature may reach 105 theoretically.
