Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates generally to a system and a process for recycling scrap, and more particularly to a system and a process for recycling post-consumer scrap linear low density polyethylene film and post-consumer low density polyethylene film.

Recycling of post-consumer plastic waste has received considerable publicity as being environmentally correct and “green.” It is known that the majority of municipal, mixed post-consumer plastic waste includes polyethylene perephthalathe (“PET”) materials, such as used in soda bottles and unpigmented high density polyethylene (“HDPE”) materials, such as milk bottles. In a typical recycling procedure, the containers composed of PET and HDPE are separated from other waste and are then shredded into smaller pieces, cleaned, heated, and extruded or granulized for reuse as other products.

One type of post-consumer (“PC”) scrap that has been difficult to recycle is polyethylene film. Typically, PC film material is a “stretch wrap” linear low density polyethylene (“LLDPE”). Because of the strength characteristics and the stretch characteristic of the LLDPE, such film is used as a baling material and as a wrap material for palletized loads or baling processes. Another type of PC film is low density polyethylene (“LDPE”), which is used as a wrap and for bags.

LLDPE film is used in wrapping and securing boxes, containers, or similar items on a pallet during shipping. Upon arrival at a given destination, such PC film is removed from the palletized materials and scrapped. Such PC film typically has labels that are glued onto the outside of the film as well as various markings that are placed on the film during the shipping process. The PC film typically is wrapped around the materials on the pallets several times so that there are layers upon layers of the PC film.

PC film is also used to bale other scrap material. When PC film is removed from the pallets or other bales, because of the high level of contamination such as dirt, oil, biological material, layering, label adhesives, etc. the PC film is either tossed in a landfill or processed as a filler for other plastic products. Reuse of the PC film as a viable blown film product for use as industrial film or a bag product has generally not been instituted. Typically, such used film has limited use due to high levels of contamination present which, in turn, causes severe processing issues as well as unpleasant properties in the finished product, for example, odor, discolorations and a “pitted” appearance.

The apparatus implementing the present disclosure must also be of construction which is both durable and long lasting, and it should also require little or no maintenance to be provided by the user throughout its operating lifetime. In order to enhance the market appeal of the apparatus of the present disclosure, it should also be of inexpensive construction to thereby afford it the broadest possible market. Finally, it is preferable that some or all of the aforesaid advantages and objectives be achieved without incurring any substantial relative disadvantage.

The subject matter discussed in this background of the invention section should not be assumed to be prior art merely as a result of its mention in the background of the invention section. Similarly, a problem mentioned in the background of the invention section or associated with the subject matter of the background of the invention section should not be assumed to have been previously recognized in the prior art. The subject matter in the background of the invention section merely represents different approaches, which in and of themselves may also be inventions.

SUMMARY OF THE INVENTION

The disadvantages and limitations of the background art discussed above are addressed by the process of the present disclosure.

There is provided a process which may be implemented in an associated system for processing a supply of post-consumer scrap linear low density polyethylene film or low density polyethylene film into near-virgin quality blown film product. The system includes a shredder configured to tear the supply of multilayered film in the shredder. The shredder exposes the surface area of the film and delaminates the film. The torn film then goes into a water bath apparatus configured to wash the torn film in the water bath, which includes a surfactant and which agitates the film in the bath. Contaminates are removed from the delaminated film in the water bath.

From the water bath, the film is moved into a grinder which is configured to grind the film. The ground film is then moved to a plurality of rotating friction washers configured to wash the ground film, wherein additional contaminants are removed from the film. A dryer is configured to dry the ground film, resulting in the ground film containing not more than 10% by weight, water content. The dried film is compacted in a compactor configured to compact the dry, ground film, without additional water, into granulated objects of near virgin quality blown film product. A conveyor network interconnects the various system equipment, with the conveyor network including one of a storage conveyor, an inclined conveyer, a discharge belt, a transport screw, and a pneumatic transport tube.

In another embodiment, the water bath may include a plurality of washers with at least one washer containing hot water. In a washer that contains hot water, the hot water is at least 140 degrees Fahrenheit and not more than 190 degrees Fahrenheit.

In another embodiment, the system includes a detector configured to detect metal in the supply of film, and includes subjecting the supply of film to a magnetic field to identify ferrous metal. Any ferrous metal detected is removed from the supply of film by a machine or by manual removal. The system may also include a detector configured as an X-ray machine to detect a non-film object.

The system may also include a granulator that is configured to form the granulated objects into pellets after they are compacted by the compactor.

There is further provided a system for processing post-consumer scrap film into a near virgin quality blown film product, with the film including one of a supply of multi-layer recyclable linear low density polyethylene plastic film and a supply of multi-layer recyclable low density polyethylene plastic film.

The system includes a detector configured to detect a non-film object in the supply of film.

The system includes a shredder configured to shred the supply of multi-layer plastic film after removal of the non-film object and to tear the shredded film exposing delaminated surface areas of the film. A filter screen is configured to receive and filter the shredded plastic film.

A water bath apparatus is configured to receive the filtered film from the filter screen. An agitator is coupled to the water bath apparatus and configured to agitate the water in the water bath apparatus to further delaminate and wet all surfaces of the shredded plastic film.

A wet grinder apparatus is configured to receive the shredded plastic film from the water bath, with the wet grinder configured to grind the plastic film. A rotating friction washer is configured to receive the wet ground plastic film, with the rotating friction washer configured to wash the ground plastic film wherein contaminants are removed. A cyclone apparatus is configured to receive the ground plastic film from the rotating friction washer, with the cyclone configured to separate a light, by weight, plastic film from a heavy, by weight, plastic film.

A pair of dryer apparatuses may be used, with one dryer apparatus configured to receive the light plastic film and one dryer apparatus configured to receive the heavy plastic film, with both dryer apparatuses configured to dry the plastic film so that the film contains not more than 10%, by weight, water content.

A compactor apparatus is configured to compact the dried plastic film received from the dryer apparatus, without the addition of water, into granulated objects of near virgin quality plastic, and the granulated objects may then be stored in a storage apparatus configured to receive the granulated objects of near virgin quality plastic film.

The method of processing the supply of film may include at least one of the washing processes using hot water having a temperature of at least 140° F., but not more than 190° F. During the process, metal may be detected in the supply of film and removed from the supply prior to the grinding process.

There is also provided a method for processing post-consumer scrap film into a near-virgin quality material suitable for a blown film product. The method includes providing one of a supply of recyclable linear low density polyethylene plastic film and a supply of low density polyethylene plastic film and removing the metal from the supply of plastic film. The plastic film is shredded after metal removal with the shredding process tearing the plastic film and exposing the surface area of the film. The shredded plastic film is discharged through a filter screen to a water bath, wherein the shredded plastic film is agitated to wet all the surfaces of the shredded plastic film. The plastic film is then removed from the water bath and a wet grinding of the plastic film occurs.

The ground plastic film is washed again in a rotating friction washer, wherein contaminants are removed from the plastic film. At least two different types of the washed ground plastic film is separated in a hydrocyclone, wherein lighter plastic film is separated from heavier plastic film. The ground plastic film is dried and compacted, without the addition of water, into granulated objects of near-virgin quality linear low density polyethylene plastic and near-virgin quality low density polyethylene plastic.

DESCRIPTION OF THE DRAWINGS

These and other advantages of the present invention are best understood with reference to the drawings, in which:

FIG. 1 is a flow chart of an exemplary embodiment of a process that may be used to recycle post-consumer (“PC”) scrap film; and

FIG. 2 is a schematic top view of an apparatus configured to process PC film in accord with some, but not all, of the process steps shown in the flow chart illustrated in FIG. 1.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

There is provided a method and apparatus for recycling post-consumer (“PC”) scrap such as PC film which is difficult to recycle because of labels that are glued on the outside of the film as well as various markings that are placed on the film during the shipping process and other contaminates. In order to provide a viable blown film product that can be reused, the labeling, adhesives, other applied markings, and contaminates have to be removed from the PC film. It is the objective of the present disclosure to process the PC film (LLDPE and LDPE) into a near-virgin quality blown film product that can be used by itself or combined with virgin material.

For purposes of this application the term “near-virgin” shall mean a quality of the PC film compared to virgin material of blown film product. A test for such quality is a visual gel detection test. For purposes of this Application a “gel” is an unmelted portion of PC film or unmelted contaminate. In the test, the numbers of gels, independent of their size, are determined on a 12 inch by 12 inch square sample. Virgin material has a gel count of between 0 gels and 10 gels. Near-virgin material has a gel count of between 11 gels and 1,000 gels. Conventional PC product has a gel count that is much, much higher than the gel count of such near-virgin material. The Applicants have compared a conventional PC product to a PC product produced with the process and the system of the present disclosure, as summarized in the following table:

Film Type	Gel Count (Range)	Gel Count (Typical)
Conventional PC	Very, Very High	52,740
Present Disclosure PC	11-1000	720
Virgin Material	0-10	9

Referring to the drawings, FIG. 1 is a flow chart of an exemplary embodiment of a preferred process for recycling post-consumer scrap film into a near-virgin quality blown film product. FIG. 2 is a schematic top view of exemplary embodiment of a system that may be configured to process PC film (through the addition of additional elements corresponding to the process steps shown in the flow chart illustrated in FIG. 1). It should be understood that the physical layout of the equipment, as illustrated in FIG. 2, is general in nature and exemplary of systems useful to process plastic scrap, and that other configurations requiring additional equipment as well as alternate equipment layouts are contemplated that require additions of equipment to or different arrangements of equipment within the boundaries of the general system layout shown in FIG. 2 to perform the processes described herein.

A supply of post-consumer scrap linear low density polyethylene (“LLDPE”) film or low density polyethylene (“LDPE”) film or a combination of LLDPE and LDPE film (hereinafter “PC film 12”) is placed onto a storage conveyor 14. Placement of the supply of PC film 12 on the storage conveyor 14 can be by any convenient and conventional method such as a forklift, crane, hoist, and in some instances manual disposition. The storage conveyor 14 moves the supply of PC film 12 to an inclined conveyor 15.

The supply of PC film 12 typically is presented in bales held together by retainer bands. In a typical operation, the retainer bands are cut and the bale is pulled apart for initial visual inspection. Such process can be done manually, or by a machine, as determined by the operator. If any non-film objects are initially seen in the supply of PC film 12, such objects may be removed either manually or by machine.

The unbaled supply of PC film 12 is then moved by the storage conveyor 14 to an inclined conveyor 15 through or near a metal detector 16 (referred to in FIG. 1 as a metal detector conveyor since the metal detector is used in conjunction with the inclined conveyor 15) to facilitate removal of certain forms of metal. The metal detector 16 typically is an induction metal detector which has several forms of magnets, for example electromagnets, to detect and assist in removal of ferrous materials automatically. It is also contemplated that a series of permanent magnets within appropriate distances to the supply of PC film 12 can be used to detect and/or remove ferrous metal objects. Other types of detectors, for example an X-ray machine, can also be used to detect non-film objects.

The inclined conveyor 15 moves the supply of PC film 12 to a shredder 18, for example a Vecoplan or Wiema shredder, that is configured to tear-shred the PC film into chunks and pieces and discharge the shredded film through a screen. The screen size and the resultant film surface area may vary depending upon operational requirements. One example of a screen is one that has a plurality of 3-inch openings.

The shredder 18 is configured to tear the supply of PC film 12 wherein a surface area of the PC film 12 is exposed. The shredder 18 also delaminates the film. Because of typical shipping wrap process, the PC film 12 is layered one layer on top of another layer and the shredder 18 is configured to delaminate such layers, i.e. separate the film layers from one another. A shredder configured to cut the film typically fuses the film layers, making cleaning the film difficult, if not impossible.

The shredded supply of PC film 12 is moved by a discharge conveyor to a first washing (and transport) screw 22. The first washing screw 22 wets the shredded PC film 12 during resonance time of the PC film 12 in the first washing screw 22, and then conveys the wetted, shredded PC film 12 to a prewash/sink/float tank apparatus 24. While in the prewash/sink/float tank apparatus 24, further separation of high density materials not recognized by the metal detector 16, for example stone, glass, or sand, occurs, since they sink to the bottom of the prewash/sink/float tank apparatus 24 for later removal. While in the prewash/sink/float tank apparatus 24, the shredded PC film 12 is further wetted by agitation, performed, for example, by a series of rotating paddles.

Additional cleaning of the shredded PC film is accomplished while in the prewash/sink/float tank apparatus 24 or subsequently by surfactants such as, for example, detergents and other compounds mixed into the prewash/sink/float tank apparatus 24 to further clean the film of contaminants such as inks, adhesives, etc.

Surfactants are substances that are added to liquids to reduce the surface tension of the liquid, thereby increasing the liquid's spreading and wetting properties. Surfactants are used, for example, to disperse aqueous suspensions of insoluble dyes. Such additives may also soften adhesives used to attach labels to the PC film 12. A preferred surfactant will include a detergent, an oxidizer, and a bleaching agent. It should be understood that the surfactant may include other chemicals or additives, including ionic and non-ionic agents. In addition to the cleaning of the shredded PC film 12 while in the prewash/sink/float tank apparatus 24, the agitation also promotes delamination of the shredded PC film 12, which has a tendency to stick to itself.

After a period of time as determined by the operator, the PC film 12 fragments are conveyed to a wet grinder 26 (also known as a first granulator). The wet grinder 26 grinds the PC film 12 and further reduces in size the PC film 12 area received from the shredder 18 and the prewash/sink/float tank apparatus 24. A typical particle size after the grinding or granulation process in the wet grinder 26 is approximately three-quarters of an inch. The grinding or granulation process in the wet grinder 26 also promotes further separation of wet labels from the PC film 12 substrate. From the wet grinder 26, the ground or granulated particles of PC film 12 are conveyed to a first friction washer 28.

The granulated particles of PC film 12 are washed in the first friction washer 28, which is configured with an inclined cylindrical trough and an inclined fast-running paddle screw to dewater and clean the granulated particles of PC film 12 discharged from the wet grinder 26. The inclined paddle screw is fixed in the housing of the friction washer 28 by means of bearings, and is enclosed in a stainless steel screen. The shredded and granulated particles of PC film 12 and water are fed at the lower end of the trough, with the inclined paddle screw transporting the material upward, and spinning at a high speed, for example 1,000 rpm.

The granulated particles of PC film 12 are washed in the first friction washer 28 while they are being transported to an outlet at the top of the trough of the first friction washer 28. The contaminates and the water are passed through the fine stainless steel screen to the trough wall, while the friction of the high speed screw further cleans the granulated particles of PC film 12. Following the first friction washer 28 is a second washing screw 22 which provides additional resonance time for the granulated particles of PC film 12 therein. Following the second washing screw 22 is a turbo washer 30 to provide additional cleansing of the granulated particles of PC film 12 and separation of contaminants from the PC film 12. Following the turbo washer 30 is a second friction washer 28 that washes the granulated particles of PC film 12 therein.

Operation of the first turbo washer 30 (as well as the second washing screw 22 and the second friction washer 28) can be either with cold water or hot water. In the case of a hot water bath, the temperature can be in the range of 120° F. to 190° F., with the preferred temperature being a water temperature of at least about 140° F. but not more than about 190° F. The hot water is used to affect additional cleaning of the granulated particles of PC film 12 in the washer in addition to the rotary motion imparted to the granulated particles of PC film 12. Temperatures over 190° F. tend to distort and/or melt the granulated particles of PC film 12.

It should be understood that friction washers 28 can be positioned in multiple different locations, such as in front of or after washing tanks (or in both such locations). As illustrated in the preferred embodiment of FIG. 1, friction washers 28 are positioned both before and after the turbo washer 30. A third friction washer 28 is also positioned after the even later in the process illustrated in FIG. 1.

Following the second friction washer 28, the granulated particles of PC film 12 are deposited in a first turbo dryer 40. The first turbo dryer 40 removes moisture from the granulated particles of PC film 12. The granulated particles of PC film 12 next move to a second turbo washer 30 wherein they are in effect rinsed with water. The rinsed granulated particles of PC film 12 are then moved (e.g., by a pump 32 as shown in FIG. 2) to a water cyclone, which is generally referred to as a hydrocyclone 34, such as for example a hydrocyclone 34 of the type produced by Herbold Meckesheim. The hydrocyclone 34 operates under water pressure from the pump 32 which moves water in a spiral to further separate contaminates from the granulated particles of PC film 12 and further separate layers of the granulated particles of PC film 12 by rotational forces of the moving water within the hydrocyclone 34.

The granulated particles of PC film 12 leave the hydrocyclone 34 at its upper end with the main stream of water, with any sinking material (higher density material) at the lower end. The hydrocyclone 34 operates in conjunction with the pump 32 and the turbo washer 30 to provide additional cleansing of the granulated particles of PC film 12 and separation of contaminants from the granulated particles of PC film 12. The water from the hydrocyclone 34 continues to transport the granulated particles of PC film 12 to (a vibrating screening apparatus 38 shown in FIG. 2 and then to) a third friction washer 36.

Upon exiting the third friction washer 36, the granulated particles of PC film 12 are deposited into second and third turbo dryers 40. The second and third turbo dryers 40 removes moisture from the granulated particles of PC film 12. (Referring to FIG. 2, a pneumatic transport system 42 may be used to move the granulated particles of PC film 12 between components.) The third turbo dryer 40 removes additional moisture from the granulated particles of PC film 12. The granulated particles of PC film 12 now are typically in the form of flakes which are then deposited into a film flake buffer silo 48.

Additional drying could optionally be performed in a thermal drying apparatus 46 (shown in FIG. 2) which uses heat to remove additional moisture from the flakes of PC film 12. In FIG. 2, a series of pneumatic transport systems 42 interconnect the various dryers and the film flake buffer silo 48. It should be understood that additional turbo dryers and/or thermal drying apparatuses could be installed in the system and coupled with the pneumatic transport systems.

From the film flake buffer silo 48, the flakes of PC film are moved (e.g., via a pneumatic transport system 42) to additional processing apparatus including a plastcompactor 50, which may be any commercially available such device. In one such plastcompactor 50, a rotating disk and a fixed compaction disk are used with both disks configured with screw-fitted and replaceable kneading rails. The flakes of PC film 12 are conveyed continuously from the film flake buffer silo 48 through the center of the fixed disk into the processing area of the plastcompactor 50 by means of a feed screw. The material is rapidly heated up by the friction against and between the compactor disks. During the operation in the plastcompactor apparatus, the flakes of PC film are warmed up because of friction and start to soften. The surfaces of the flakes of PC film 12 start to fuse, resulting in worm-shaped formations. The additional heating in the plastcompactor 50 further reduces moisture in the worm-shaped formations of PC film 12. In a typical operation of the methods described herein, the PC film 12 has a moisture content of not more than 10% by weight.

From the plastcompactor apparatus 50, the worm-shaped formations of PC film 12 are moved to a second granulator 52 which reduces the worm-shaped formations of PC film 12 to the required agglomerated granulated object size. The specific size of the agglomerated granules of PC film 12 is selected by changing a screen inside the second granulator 52. The second granulator 52 further removes any additional moisture from the granules of PC film 12 and compacts the dry ground granules of PC film 12, without addition of water, into granulated objects of near-virgin quality blown film product.

In one embodiment of the method, a controller 54 is used to control the various functions of the apparatus including water temperatures, air pressures, time periods, the specific machine granular size, and the speed of operation.

The controller 54 may be a microprocessor coupled to the various apparatus of the system. The controller 54 may also be a server coupled to an array of peripherals, or a desktop computer, or a laptop computer, or a smart-phone. It is also contemplated that the controller may be configured to control each individual machine, and may be remote from any of the apparatus. Communication between the controller 54 and the various apparatuses may be either by hardwired or wireless devices. A memory/database coupled to the controller 54 may be remote from the controller 54. The controller 54 typically includes one or more input devices, for example a mouse and/or a keyboard, and a display device, for example a monitor screen or a smartphone. Such devices can be hardwired to the controller or connected wirelessly with appropriate software, firmware, and hardware. The display device may also include a printer coupled to the controller 54. The display device may be configured to mail or fax reports as determined by a user. The controller 54 may be coupled to a network, for example, a local area network or a wide area network, which can be one of a hardwired network and a wireless network, for example a Bluetooth network or an Internet network, for example, by a WI-FI connection or a “cloud” connection.

In another embodiment a water treatment apparatus 60 is coupled to the various wash apparatus to recycle and filter the water used within the system for continued use. The quality of the water will vary at various stages of the process, with the recycling and filtering of the water controlled by the operator and/or in conjunction with the controller 54.

In a further embodiment, one or more testing stations may be installed to test the quality of the PC film 12 being processed. One such test is the “gel count” test described above. However, other appropriate tests can be implemented as determined by the operator. The test stations can be coupled to the controller 54 to automatically monitor, test, and report results by configuring the controller 54. Testing is typically performed at various stages of the process as determined by the operator.

For purposes of this disclosure, the term “coupled” means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or moveable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or the two components and any additional member being attached to one another. Such adjoining may be permanent in nature or alternatively be removable or releasable in nature.
