Description

"CONTAMINATED PLASTIC PACKAGING RECYCLING SYSTEM" INTRODUCTION

[1] mankind's greatest problem in contemporary times is translated into the generation of waste in all sorts of nature (organic such as food, leaves, seeds; chemistry, physics such as polymers, metals, ceramics, glass; physicochemical throughout type of activity developed by society (domestic, urban solid, industrial, hospital, nuclear, construction and / or demolition waste), where the said waste is popularly titled "waste".

[2] Taking as reference only the universe of 'solid waste' type waste, currently, according to 2010 Census and CEMPRE data [1], around 200,000 tons of solid waste are generated per day in Brazil, with growth of 7-10% per year, which means a consumption of 30% more than the planet can naturally replenish. In addition, about 40% of waste ends up in landfills and dumps without proper treatment. With all this Brazil annually loses $ 8 billion by burying the garbage that could be recycled.

[3] Thus, the National Solid Waste Law 2010 (12.305 / 10) was instituted to drive recycling from the definition of clear rules within the principle of shared responsibility between government, companies and the population, building solid foundations for this market. , emerging and promising, and formalizing the whole chain.

[4] The PNRS (National Solid Waste Policy) provides for sectoral agreements and shared responsibility between companies and government, including society, to increase recycling rates through reverse logistics of their products. However, it is not enough just to collect, it is necessary new industrial technologies capable of decontaminating the materials in the recycling process, obtaining recycled raw material of higher quality and economic value, to be reused in the manufacture of the same product, closing the cycle in the reverse logistics chain. .

[5] Recycling will stimulate the economy of raw materials and contribute to income generation in the sector. The use of recycled input in the industry generates economic gains because the cost is lower compared to virgin raw material, not to mention 70% energy savings over virgin resin production, and natural resources such as oil and gas. Water.

[6] Given this scenario, the percentage of packaging of different types that is collected after the use of products and returning to industrial production is increasing. Despite the increased cost of collection, the environmental, social and economic gains are much greater. In this way, private companies are engaged in order to increasingly stimulate recycling.

APPLICATION FIELD

[7] The present title patent and object of description and claim in this application is an inventive solution which has outstanding benefit to various segments of Industry, namely, Industry and Distributors of Lubricating Oils, Greases, Fertilizers, Industry. Plastic Processing and Plastic Recycling Industry.

[8] Notably the present invention is intended for use in the process of recycling polymeric materials, which will be defined herein as a recycling equipment for plastic containers contaminated with lubricating oil, greases and fertilizers, with oil recovery, greases and fertilizers. and without wastewater generation.

[9] Specifically, the "equipment that permits the treatment and decontamination" of polymeric material in its recycling has as its paradigm the packaging of lubricating and related oils and is therefore an equipment with a stated objective to provide the removal and recovery of contaminants ( oils and greases) impregnated in the body of this type of packaging, delivering at the end of the process a volume of recycled thermoplastic polymer material with higher quality and economic value and no environmental impact on the process through the non-use of water and no generation of liquid effluents (value priceless).

DEMAND OF INVENTION

[10] a. Lubricating Oil, Grease and Fertilizer Industry and Distributors: The application of the invention meets the need and interest of environmental and economic gains, with the best economic and environmental solution for the disposal and treatment of its post-consumer products through decontamination. and recycling of post-consumer plastic packaging contaminated with lubricating oils, greases and fertilizers, as it will allow the separation and recovery of both plastic and residual oils, greases and other chemicals contained in these packages without the use of water and wastewater generation. . Thus, these industries and their distributors were able to best comply with the National Solid Waste Policy (National Law 12.305 / 10) and complete the reverse logistics cycle of their products placed on the market, obtaining a totally recycled plastic material. high quality decontaminated, enabling the production of new packaging, now recycled and sustainable. In addition to the reuse of lubricating oils, greases and fertilizers, removed and recovered from post-consumer packaging.

[11] b. Plastic Processing Industry: The application of the invention meets an emerging need for new sources of supply of plastic raw material for growing demand for thermoplastic products, notably for packaging and thermoplastic resins, which are asking for an environmental issue each time. increasingly the use of quality recycled material over virgin material; and [12] c. Plastic Recycling Industry: The application of the invention meets an environmental, technical and economic need in the difficult to process contaminated plastics recycling sector, where it is explicit that this activity must be provided with maximum efficiency as well as be a "clean" and "sustainable" activity that minimizes the use of water (non-renewable natural resource) and also without the generation of effluents. In addition to the relevant importance, the recycling industry demands a production scale that is adequate to local demands, since its installation and controls are easily accessible to the available manpower levels in the most diverse regions of the country.

[13] In brief synthesis the demand of the invention can be summed up by the increasingly pressing need to obtain the maximum possible volume of materials of economic interest with environmental gains, either in the form of recycled plastic or in the volume form of lubricating oils. , greases and fertilizers recovered through ecologically sound industrial activity.

PARADIGM OF THE INVENTION

[14] According to what is revealed in the demand topic of the invention, "contaminated plastic packaging recycling equipment" meets the rigorous guidelines of the national solid waste policy (national law 12.305 / 10), fully realizing the "reverse logistics" cycle of its products placed on the market, obtaining a recycled and totally decontaminated plastic material of high quality and sustainable.

[15] In addition, the use of recycled input by industry in addition to generating economic gains contributes to solving the problem of waste generation in the urban environment. By way of example, for every 01 (one) ton of recycled plastic, 5.7 m3 of landfill is no longer used, saving 70% of energy compared to the production of virgin resin, in addition to saving natural resources such as Petroleum. and water [1].

[16] Lastly, and as important as the economical and sustainable disposal of discarded plastic material, notably in the form of packaging, the use of large amounts of water in recycling processes must be taken into account. its use in industrial activities, as it is an exhaustible natural resource, the generation of liquid effluents and inefficient decontamination in the recycling process of some products.

[17] According to how much argument can be said that the paradigm of the invention is to create a new model and standard for recycling polymeric material, notably from contaminated packaging, and is therefore a sustainable solution for recycling solid waste, especially those difficult to solve, providing greater environmental, economic and social gains for the entire industrial chain of the country, society and government.

INVENTION REQUIREMENTS

[18] In line with the demand and paradigm of the invention the applicant has devised an unprecedented "contaminated plastic packaging recycling equipment" provided with novelty associated with inventive activity, as it is not obvious or evident from other solutions known in the state of the art. for packaging decontamination in the recycling process.

[19] In addition, the "invention" is provided with industrial applicability, is economically viable and therefore meets the stringent patentability requirements, notably as a patent for invention, as set out in Articles 8 and 13 of Law 9.279.

TECHNICAL BACKGROUNDS

[20] In order to provide truthfulness and to consolidate the context set out in the introductory table topics, an explanation of the state of the art will be provided by state-of-the-art solutions developed for the decontamination of plastic containers contaminated with lubricating oils, greases, fertilizers, chemicals in general, which have undergone critical analysis, where the problems and causes of these problems will be well defined, which in turn justify the needs of previously listed technical, economic and environmental orders.

[21] a. Recycling concept: It is the reuse of processed materials as raw material for a new product. Many materials can be recycled and the most common examples are paper, glass, metal and plastic. The biggest advantages of recycling are minimizing the use of natural, often non-renewable sources; and minimizing the amount of waste that needs final treatment, such as grounding or incineration.

[22] b. Recycling plastics: consists of the process of recycling artifacts made from resins (polymers), usually synthetic and derived from petroleum. For purposes of the present invention, only the universe of materials recycled from packages of a polymeric nature, such as polypropylene packages will be considered; Low Density Polyethylene; High density polyethylene; Acrylic nylon; Polyvinyl chloride); and Poly (ethylene tereflalate) among others.

[23] c. From the conventional recycling process: it is recognized by the following macro steps: - Receipt, Selection and Classification: receipt of post-consumer plastic waste, still as a final product for manual separation according to type of plastic and color. - Grinding: With the material already classified by color and type, the grinding is done through a equipment called mill. In the mill the material is crushed and reduced to small pieces whose size (grain size) is determined as a function of the size of the holes in its sieve. In this process, water can also be injected into the mill so that internally generated friction will facilitate the separation of contaminants present in the material, such as soil, sand, paper labels and others. - Washing: The milled material in the mill undergoes a water injection centrifugation process in a washer to remove impurities impregnated in the material. The washer consists of a shaft that rotates at high speed inside a perforated sieve tube. The spindle speed conveys the material and centrifuges part of the contaminants through the tube holes, washing and rinsing the ground material;

Decontamination: After the washing process the decontamination is done in a settling tank. The settling tank consists of a tank with a liquid, usually water, where the decontamination of impurities is made using the principle of density of materials with respect to water. The more or less dense plastic material with respect to water is separated from its contaminants by flotation or decantation; -Drying: The decontaminated material goes through a centrifugation process in the dryer. The dryer consists of a shaft that rotates at high speed inside a perforated sieve tube. The spindle speed conveys the material and centrifuges water through the holes in the tube; - Extrusion / Granulation: The extrusion process takes place in an extruder consisting of a steel cylinder with an endless thread inside. This cylinder is covered by electrical resistors that heat the cylinder and transfer heat to the plastic as it is transported by the thread, it melts and mixes, generating a molten mass that goes through a filtering process, where they are impurities removed that may interfere with the quality of the final product. This molten mass of the already filtered polymer exits through a matrix that will give it the shape of noodles and is later cut into granules through a shredder. The granulated material has a large advantage over the ground because it is free of contaminants, has better homogenization and generates increased productivity in the manufacturing processes of plastic artifacts. - Packaging (Packing / Palletizing) / Shipping: Processed materials are packaged in 25Kg clear valve bags or 100Kgg Big-bags, depending on customer requirements. The bagged materials in 25 kg valve bags are placed on pallets and tightened for better packaging and transportation. Each pallet is made up of 40 bags (100,000 kg). They are then shipped for destination with transformers of polymeric material, ie, to be used in the conformation of all kinds of products, such as packaging.

[24] By way of example, this conventional process of recycling polymeric material is shown in Fig. 1.

[25] d. Critical analysis: as evidenced by the paradigm topic of the invention and according to the conventional thermoplastic material recycling process, and in particular for the recycling of contaminated packaging the packaging contaminated with lubricating oils, greases and fertilizers for This critical analysis the inventor chose the washing and decontamination steps.

[26] As it turns out, the above steps of washing and decontamination require a large volume of water and detergent or surfactant, which from an environmental point of view is extremely negative given that, as already argued in the introductory framework, water is a non-renewable natural resource. , therefore being critical its use.

[27] Another negative aspect resulting from the use of large volumes of water is the fact that a contaminated effluent, which, even treated, is generated as a residual waste from the washing process, which generates a solid "water + oil" residue which in turn should instead be destined for incineration in order to avoid environmental contamination. However, incineration is an expensive and unsustainable process due to the high energy demand, and consequently little applicable by the polymeric material recycling industry.

[28] In turn, the lubricating oils, greases and fertilizers present in this effluent are considered hazardous waste due to the high power of contamination of the environment, soil and water.

[29] By way of example only 01 (one) liter of lubricating oil is capable of contaminating 01 (one) million liters of water [2]. Considering that the consumption of lubricating oil has increased significantly in the last 10 years, data from Sindiplast and Sindicomt2] '[3] pointed out that in 2004, being only lubricating oils in general, among these automotive and industrial, 305 million packages were produced. plastic bottles, including bottles, jugs, buckets, gallons and one (1) liter bottles, corresponding to 25,100 tons this year. In São Paulo alone, the one (1) liter bottles corresponded to a volume of 150 million units (7,500 tons). In 2013, approximately 800 million liters of automotive lubricating oil were produced and one (1) billion liters in total, including automotive, industrial lubricating oils and greases, doubling the volume of packaging produced in the last 10 years.

[30] In a nutshell, according to the scenario of exponential increase in demand for lubricant oil packaging, which must be associated with demand for other types of products (greases and fertilizers) that also make use of the same type of plastic packaging. It is evident that the current model of recycling system of polymeric packaging contaminated by this type of product is exhausted, since the water consumption in the recycling process is directly proportional to the increase of its demand.

PROPOSAL OF THE INVENTION

[31] a. Objective: To make the reuse of polymeric material from contaminated packaging of lubricating oils, greases and fertilizers feasible, in a recycling process that does not make use of water and no generation of contaminated effluents, thus closing the reverse logistics chain, giving this material discarded economic interest with environmental gains, as well as helping to reduce the ecological liability of companies that industrialize and market products of this nature, thus meeting the already evidenced demands of environmental, economic and social order.

[32] New recycling equipment should also afford high-quality industrial scale production with higher added value and better reuse in the production process (greater applicability) from an economical point of view rather than an obsolete recycling process from the point of view. economic and environmental view.

[33] Ultimately, from the ecological point of view, the new inventive recycling equipment contributes to the preservation of the environment in view of the impacts of these previously discarded materials (packaging and contaminated waste material in the form of lubricating oils, greases and fertilizers). ), and this benefit is even more relevant when taking into account the exponential growth in consumption of this type of input [34] b. Expected technical effect: In a brief synthesis it is possible to list the following design requirements for the unpublished "Contaminated Plastic Packaging Recycling Equipment", namely: - to guarantee an effective and total decontamination of the discarded polymeric material; - ensure ecologically sustainable decontamination; - Ensure the reuse of the solvent used in the decontamination process; ensure the recovery of oil lubricants, greases, fluids, fertilizers, chemicals generally present in packaging; ensure no generation of contaminated liquid effluents through closed and renewable circuit; - guarantee industrial scale of production - guarantee its economic and financial viability; and - Ensure at the end of the recycling process that both polymeric material from the packaging and a certain volume of lubricating oils, greases, pesticides and chemicals are obtained, all of which are of economic interest.

[35] c. Distinctive feature: To make the benefits and technical effect of the introduction of the unpublished "Contaminated plastic packaging recycling equipment" feasible, it was conceived from an inventive concept based on a closed and continuous system, where it is used. natural solvent, where the contaminant material (lubricating oils, greases and pesticides) is removed and separated from the plastic packaging, allowing its recovery and polymeric material on an industrial scale without loss.

The milling size (grain size) can be selected by the size of the holes of a sieve (PE) which is finally communicating the conveyor thread (RT) that will feed the separator device I [Di2];

[45] Separator device I [Di2]: As shown in Figure .4, where in a preferred embodiment it has a constructivity composed of a horizontal tank [bl] of circular or even polygonal section, the interior of which, when operational, contains a fixed volume of clean solvent (Sol), where this tank has at its top an access duet [b2] through which it is fed a volume of ground contaminated polymeric material [Mpl], and at its opposite bottom an opening is defined [b3], communicating with the inclined tank [cl] of the drying module [m3]. Still within the horizontal tank [bl] is defined an endless thread (b4) and a fluid stirring device [b5], either mechanical or ultrasound, which improves the fluidic conditions for the removal of contaminants (oil, grease, fluids, etc.). The endless thread (b4) is intended to ensure decontamination and transport of the volume of decontaminated polymeric material [Mp2] to the drying device [Di3];

[48] c.Recycling process: is carried out according to sequential steps, as shown in figure .6, which will be detailed in the following paragraphs.

[49] System set-up step [El]: where the horizontal tank [bl] and the inclined tank [cl] have their bottoms and communicators through the transition opening [b3], filled with a certain volume of solvent. natural organic [Sun];

[50] Grinding step [E2]: Contaminated plastic packaging [Mp] is fed into the feed belt (EA), which will transport these packaging to the mill (MO), where the volume of contaminated plastic packaging [Mp] is ground. through the system of rotary and fixed knives, notably by the encounter of the fixed knives (FF) with the rotary knives (FR), making the cutting of the material, where after this cutting the volume of cut material passes through a sieve (PE) filtering the size of the ground material and only allowing the particle to exit at the previously specified granulation, thereby generating a volume of ground contaminated polymeric material [Mpl] which in turn follows to a carrier thread (RT) which will feed the separation module I [m2] ;

[51) First Separation Step I [E2]: The volume of ground contaminated polymeric material [Mpl] is poured into the horizontal tank [bl] already loaded with a fixed volume of natural organic solvent [Sol]. This time the volume of ground contaminated polymeric material [Mpl] is immersed in this fixed volume natural organic solvent [Sol]. The action of the endless thread [b4] and the fluid stirring device [b5] converge on the dissolution of the contaminated material (Mc) from the surface of the ground contaminated polymeric material [Mpl], thus generating a volume of wet decontaminated polymeric material [ Mp2] and a volume of contaminated solvent [So2] inside the horizontal tank [bl] This volume of wet decontaminated polymeric material [Mp2] is continuously conveyed by the endless thread [b4] over the entire length of the horizontal tank [ bl] until poured into the inclined tank [cl] of the drying module [m3];

At this point the water vapor injection device (c6) is actuated, thus generating the water vapor injection next to the volume of wet decontaminated polymeric material [Mp2], determining the runoff of the contaminated solvent [So2] that precipitates by gravity. at the bottom of the inclined tank [cl]. Water and solvent vapors generated in the drying process are collected through the opening [c 7] from which condensed water is recovered to feed the water vapor injection device itself (c6).

[53] Alternatively, the drying device (c5), generated by radiant heating (infrared light) or hot air flow, among others, may also be activated, evaporating any excess contaminated solvent (So2) loaded with wet decontaminated polymer material [ Mp2], where in this case the generated vapors are sent to the distillation equipment (D) of the separation device II (Di4), [54] At the end of the step a volume volume of dry decontaminated polymeric material [Mp3] is obtained. transported by the endless thread [c4] to the outlet nozzle (c2) being poured into a silo from where it will proceed for the extrusion and granulation process itself, and later for packaging and shipping.

[55] Separation step II [E5]: The contaminated solvent [So2] present inside the horizontal tank [bl] and inclined tank [cl] is gravity flowed through the drain [d5] into the heating vessel (d2) which communicates with the evaporation vessel (d3), where it generates a vapor volume of the decontaminated solvent [So3] that goes to the condenser (d4), and by exchange heat with the cooling water returns to liquid state and by gravity is again fed into the separator device I [Dil] of the separation module I [m2]. In turn, a volume of recovered material (MR) is generated, notably lubricating oils, greases, fertilizers, chemicals of general economic interest, which is drained through the outlet nozzle [d6], leaving the separator device II (Di4). ready for a new operation.

[56] In addition, when the volume of recovered material (Mr) is sufficient to fill the heating vessel (d2), the spare heating vessel (d2 ') will automatically be used and consequently the spare evaporation vessel (d3). ').
