Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a food waste garbage bag and a garbage bag,

The present invention relates to a method for preventing malodor caused by spillage of food wastewater and contamination of food waste containing a large amount of water when treating food wastes capable of recyclable resources, and is characterized by comprising a harmless polymer and a natural antimicrobial agent extracted from plants Which can physically separate wastewater from food wastes by using the composition, and thus is advantageous for the resource recycling process of food wastes. In the collection step, the waste wastes and food wastes are maintained in a solid state, The present invention relates to a waste garbage bag to which a waste garbage solid waste composition is applied.

Generally, the process of food waste appears in a variety of ways.

First sales of food. Foods that are discarded during the distribution process, foods that trim and discard food during cooking, such as homes and restaurants,

 Second, it refers to the food wastes of agriculture, fishery, aquatic products that have been left for food and food left over after the distribution period.

Third, in the agriculture, fishery, wholesale market, etc., there is a part that can not be eaten during sales and transportation.

Fourth, the damaged parts of the food purchased at the home, restaurant, etc. are generated, and the food waste left over due to too much diet is generated.

Fifth, food that has been stored for too long by purchasing more than necessary food, and food that has been deteriorated by carelessness are disposed of as garbage.

According to the Ministry of Environment data (2000), the ratio of food waste generation is as follows.

Food waste generation rate by source Sum
home food  point Large retailer (market, others) cafeteria 100%
53% 30% 12% 5%

Percentage of garbage incineration Sum
Small The Grocery fruit   Flow 100%
53% 29% 13% 5%

In addition, we can confirm the economic loss calculated by the Ministry of Environment in 2000 as follows. Since then, more than a decade later, we believe there will be more food waste, but we do not think there will be any explosive growth because the population growth rate is not so high.

The amount of food waste that is discarded is converted into money, reaching the annual trillion won.

It costs more than 400 billion won to dispose of garbage. Especially, garbage is quickly corroded, so it is costly to process. The easy recycling of abandoned food waste into livestock feed can significantly reduce the import of grain for feed. Korea's food self-sufficiency rate is only 30%, and dependence on imported grain is 96%. In 1988, it consumed a small amount of foreign currency for importing scarce feed grain for USD 1.8 billion and USD 2 trillion per year. This waste of food will lead to price hikes of agriculture, fishery and aquatic products, and it will surely return to consumers. It is required to easily treat food waste

Food waste contains more than 80% water and is composed of easy-to-apply organic materials. When food waste is landfilled, odor caused by nitrogen and sulfur compounds, and flies. Mosquitoes and other pest breeding, high concentration leachate is generated, and it takes a lot of processing cost, and when the landfill is mismanaged, it is not limited to the waste problem, Water quality. soil. The problem of groundwater contamination also occurs. In case of incineration, the incineration efficiency is lowered due to the low calorific value and the high water content of the food waste, and incomplete combustion increases the possibility of releasing various harmful substances.

The general food waste disposal process can be broadly divided into food waste generators (households and restaurants), collection and transportation (administrative agencies), and final disposers (landfill, marine dumping, feed, fertilizer, fermentation methane gas and biofuel) . In the whole process, the odor and discomfort caused by the decay of food waste and the leakage of negative waste water are the biggest problems.

 In the case of a home, it is collected from the administrative institution once a week on average, so it must be collected from the house for a week. In this process, it is corrupted and stinks and it interferes with maintaining a comfortable living environment. Moreover, In the process, the leakage of odor and waste water is very painful.

 In the case of administrative agencies, the suffering caused by the smell and waste water caused by corruption during the collection and transportation is serious.

 Most of the final processors are fermented to produce methane gas collection, fermented fertilizer, and fermented feed, but there are not many factories that are operating due to odor and unpleasantness. And it is difficult to start the factory due to the complaints around.

According to the London Convention, which was signed in 1993, Korea has been banned from dumping water from food wastes this year. However, there is a concern about the realization of 'waste disaster' due to lack of food waste disposal facilities. According to the Seoul Metropolitan Government and the ward office, food processing companies are asking for an increase in the cost of processing waste as food waste wastewater is completely banned. As of the Seoul metropolitan standard, it is estimated that the economic burden of about 50,000 won per ton increases. Currently, the remaining 16 districts of the 25 districts of Seoul excluding Songpa-Dongdaemun Seodaemun Dobong Gangdong-gu, I have used the company.

The government has been able to discard the waste in the sea since 1988 due to environmental problems such as odor and groundwater pollution due to lack of landfill and food waste. After joining the London Convention in 1993, the marine dumping of wastes continued. Waste exporters have preferred marine dumping because the cost of off-shore wastes is as much as 90% lower than on land. Until last year, the companies have abandoned food waste wastewater in the 125 waters east of Pohang, the 63 western part of Ulsan, and the 200 western part of Gunsan. The London Convention is an international treaty designed to prevent marine pollution from waste dumping, and currently 87 countries have joined and South Korea joined in 1993. Korea will ban livestock manure and sewage sludge from 2012, food wastewater from 2013, and industrial wastewater and wastewater sludge from 2014. For example, in Seoul, which has the most populous population, the daily amount of food waste is 3347 tons and the amount of waste water generated is 1800 tons per day. Of these, 54% (996 tons) are processed in public facilities, It has done its own processing or marine dumping.

Therefore, the problem of waste water has a problem of developing a treatment method.

Sodium polyacrylate derivatives can be used to solidify such waste water. However, the derivatives are used as emulsifiers and thickeners in a water-soluble liquid state, dispersants in natural or synthetic rubber, softeners in synthetic fibers, flocculants, plasticizers, Absorbent resin and the like. In the field of agriculture, horticultural landscaping has been used to slowly releasing moisture while keeping moisture for a long time. In particular, highly hygroscopic resins are widely known as compounds which are essential for baby diapers and feminine sanitary napkins.

  In 1974, the US Department of Agriculture's Northern Research Institute developed a resin with an absorption capacity of about 1000 times, and became interested in its manufacture and application. However, unlike earlier expectations, nothing was industrialized except for baby diapers and women's sanitary napkins. Especially, it was expected to be widely used for agriculture but it is not used as much as expected.

As a result of these problems, Patent No. 435130 has proposed a garbage bag which neutralizes the smell and absorbs liquid.

The garbage bag has disadvantages in that it is inconvenient to use an absorbent material in which the odor neutralizing composition is immersed or a separate garbage bag.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and the object of the present invention is to use sodium polyacrylate derivatives as a high absorptive property for food waste decay prevention and easy waste water treatment. This superabsorbent absorbs all of the moisture in the food to absorb the moisture necessary for the survival of the microorganism and gels it, thereby making the microorganism in the food garbage non-viable. The present invention also relates to a food garbage disposal wastewater solidifying agent composition for preventing the generation of odors due to corruption and corruption by inhibiting the propagation and sterilization of germs present in the wastewater absorbed in the highly hygroscopic resin by using an antibacterial agent, It is an object of the present invention to provide a food garbage bag to which a garbage disposal wastewater solid agent composition is applied.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Various changes and modifications may be made by those skilled in the art.

Brief Description of the Drawings Fig. 1 is an explanatory view showing an envelope of a food waste negative wastewater solid agent composition according to the present invention,
FIG. 2 is an explanatory view showing a food garbage bag to which the food waste negative wastewater solid agent composition bag according to the present invention is applied;

The present invention relates to a composition for absorbing all the moisture of food waste with a superabsorbent resin to make an environment in which microorganisms can not grow, thereby solidifying the waste water in the food garbage bag and delaying the decay.

In the present invention, the composition of the present invention is inserted into a food garbage bag from a household, so that the food garbage is passed to the collection agency in a state in which the waste water does not leak out without being decayed.

The composition used herein is a composition comprising a highly hygroscopic resin and an antimicrobial agent. As a highly hygroscopic resin, SAP (Super Absorbing Polymer) widely used in diapers and sanitary napkins is used to form a hydrogel to absorb the moisture of food waste and to create an environment in which microorganisms can not be absorbed, And a composition for preventing the propagation of microorganisms and removing more than 99.99% of the microorganisms in the absorbed water by using natural antimicrobial agents. The highly hygroscopic resin is a poly (acrylate) -sodium polyacrylate (sodium polyacrylate) having a three-dimensional network structure due to contact with moisture. The ion component of sodium (Socium) Refers to a polymer structure capable of swelling a large amount of water in a three-dimensional network structure by holding water in a three-dimensional network.

As a highly hygroscopic resin (SAP), sodium polyacrylate absorbs more than 1000 times of distilled water in its own weight, absorbs 300 times in ordinary tap water, and absorbs 0.9% NaCl, urea, and human waste Absorbs 60 times.

The difference in the amount absorbed by these three kinds of aqueous solutions is due to the electrolyte concentration. Since food wastes also contain salt and various other liquids, the amount of water absorption can be expected to be about 30 to 60 times. That is, 0.5 to 3.2 wt% or more of sodium polyacrylate of food waste is required.

The adsorption rate of sodium polyacrylate on the market differs depending on the properties of the product irrespective of the average molecular weight of the polymer. In other words, depending on the size of the particles, there is a difference depending on how much moisture and contact area are increased. In addition, the crosslinking density of the highly hygroscopic resin is high and the absorption rate is not increased. The strength of the hydrogel depends on how much absorbed water is stored in the three-dimensional network structure of the hygroscopic resin. The strength of the hydrogel after moisture absorption of the highly hygroscopic resin is not closely related to the absorption rate, but has a series of relationships with particle size and shape.

A super absorbing polymer is a functional resin having an ability to absorb and retain moisture such as water several tens to 1,000 times its own weight, and is used for moisture absorption in the present invention.

The kind of the highly hygroscopic resin is not particularly limited in the present invention, and almost all of the materials used for hygienic materials such as paper diapers, sanitary articles, and the like can be used. Specific examples thereof include polyacrylate-based crosslinked products, crosslinked products of vinyl alcohol-acrylate copolymers, crosslinked products of maleic anhydride-grafted polyvinyl alcohol, crosslinked products of acrylate-methacrylate copolymers, methyl acrylate- A cross-linked product of a starch-acrylonitrile graft copolymer, a cross-linked product of a starch-acrylonitrile graft copolymer, a carboxymethylcellulose cross-linked product, an isobutylene-maleic anhydride copolymer A cross-linked polymer, an isobutylene maleic acid copolymer, a polyacrylonitrile polymer, a polyethylene oxide crosslinking agent, a copolyacrylate salt, a polyamide and a vinyl pyrrolidone copolymer.

In the present invention, the highly hygroscopic resin may be used alone or in combination of two or more. In addition, the highly hygroscopic resin used in the present invention should have a proper particle size in order to maximize antibacterial and deodorizing functions by contact with air. Specifically, the average particle diameter is usually 5 to 1,000 占 퐉, preferably 20 to 800 占 퐉. If it is less than 5 mu m, it is difficult to handle. If it exceeds 1,000 mu m, it is difficult to uniformly adsorb other composition components and the surface area is reduced, so that more effective absorption, antibacterial and deodorizing functions can not be obtained.

The present invention uses sodium acrylate and polyacrylate type highly hygroscopic resin, which are known as edible materials, as monomers for quaternary ammonium salts in consideration of recycling of food wastes.

The high hygroscopic resins usable in the following Table 5 and their physical properties are shown.

The chemical structure of the polyacrylate salt is shown in Chemical Formula (1). Here, M is an alkali metal such as sodium or potassium, and R is hydrogen or a variety of organic compounds or polymers having a double bond in a molecule as a crosslinking agent.

The antimicrobial agent used can be selected from the products used in food packaging and food container cosmetics. These antimicrobial agents are excellent in lactic acid, sorbic acid, citric acid anhydrous, cupric sulfate, copper (metal: red luster) and ductility (elongation property) ), It does not dissolve and extinguish harmful bacteria such as O-157 bacteria and Legionella bacteria with the characteristic of ion, Glycerin Esters of Fatty Acid, Propylene glycol, 1,3-butyleneglycol, 1,2-hexanediol, Inorganic compound in the form of alkali silicate aluminum hydrate of alkali and alkaline earth metal, inorganic compound composed mainly of silicic anhydride and aluminum oxide, and tourmaline, and using a natural antibacterial agent harmless to the human body made of a complex compound using one or more of the above- .

In the present invention, it is preferable to use 0.001 to 10 wt% of the weight of the high hygroscopic resin composition used for prevention of corruption and prevention of waste water leakage. The antimicrobial agent is added in a small amount in an amount of 0.001 to 4% of the highly hygroscopic resin, thereby completing a composition capable of generating an antibacterial activity.

In using a packaging material for inserting the above-described composition into a food garbage bag, a packaging material is used which is easily absorbed in water (liquid water) and easily decomposed or separated when moisture is applied. Most paper or film-type products made of biodegradable water-soluble polymers are used.

In the present invention, a highly hygroscopic resin and a product containing the composition are manufactured by using a packaging material using paper as a main substrate, and inserted into a food garbage bag using a stick-type packaging material. The amount of highly hygroscopic resin added to the packaging material is 5 g or more and 100 g or more, and the most preferable method is to manufacture a product having 8 g to 20 g, considering the swelling volume of the food garbage bag after moisture absorption It is preferable to adjust the moisture absorption amount by adding or subtracting the number of stick sticks.

The composition envelope (2) of the stick rod can be either circular or square. As shown in FIG. 1, it is preferable that the stick rod having a circular motion shape is set to a length of 1 cm to 30 cm and preferably 10 to 20 cm Considering the food garbage bag, it is preferable to have the joining portion 1 at the upper and lower ends and have a thickness (or diameter) of 0.5 cm to 5 cm and a proper thickness of 1 cm to 2 cm.

The form of the garbage bag 3 in the form of a package of the composition product is shown in Fig.

In the present invention, it is an object of the present invention to provide a more pleasant surrounding environment in which food is decomposed and odor is not generated during the entire treatment of food waste, thereby realizing a working environment.

(1) The amount of water absorption was measured by putting food waste in a state of moisture content of about 50 to 60% in a 1 L bag

In the present invention, it is important that the entire process for the generation, collection, transportation, and final treatment of food waste is important in the treatment of food waste, and the present invention is not a technique focused on any one part but is a technique considering the entire process.

In the process of food waste generation, only the mechanical method of crushing, drying or dehydrating was performed, and this technique is shown as a next step, which is completely independent of the collection and transportation stages. This is because drying does not decay, but in actual collection, food waste in various states is mixed and left to decay.

In the present invention, the food waste is decontaminated by a physical method of absorbing moisture and antibacterial, so that it can be operated not only in a home but also in a collection and transportation process, .

In order to be used as fertilizer and feed in the final treatment process, it does not affect even if it is used in fertilizer and feed by using trace amount of natural antimicrobial agent which is harmless to human body. And because it uses highly hygroscopic resin, it is excellent in water-containing characteristics. When it is recycled as fertilizer, it has excellent moisturizing effect on the ground. It can prolong the time that fertilizer is absorbed in soil and can be decomposed into monomers having biodegradability So it has no effect on the quality of the soil.

When it is used as a feed, it easily separates from food garbage. Because it absorbs moisture among hygroscopic resins and absorbs only waste water using a composition of highly hygroscopic resin that maximizes the entanglement phenomenon like gel, it absorbs only food waste and solid food garbage Since separation is easy, there is no problem collecting only food waste and recycling it as feed.

  In the final stage of the bio-solid fuel manufacturing process, the highly hygroscopic resin contains an organic compound (sodium polyacrylate and its derivative) having a high heating amount, thereby increasing the amount of heat generated by the solid fuel.

1 is a view illustrating a method of packing a highly hygroscopic resin for preventing the decay and leakage of waste water used in the food garbage bag of FIG. 1 according to the present invention.

First, the composition used to prevent waste water leakage and to inhibit decay is as a metal salt polyacrylate derivative, a superabsorbent resin that forms water-absorbing hydrogel, absorbs all the moisture of food waste, and creates an environment in which microorganisms can not grow / RTI > (Polymer), which has the function of preventing waste water leakage and decaying. Secondly, it is characterized by using natural antibacterial agent used in cosmetics, food containers and household detergents.

These antimicrobial agents are permanently bonded to the highly hygroscopic resin, and thus can be said to block the microbial propagation in the negative wastewater and to block the bacteria from living. Depending on the characteristics of the food waste final treatment process, it is possible to treat it selectively. That is, if the final treatment is incineration, landfill, fertilizer, bio-solid fuel, it can be recycled without problems even if it contains the components of the present invention. When used in feed, the composition of the present invention, which already contains solid wastewater already in the form of a solid gel, is easily separated and then recycled as feed. Thus, the problem can be solved by selectively performing final processing.

Thus, the natural antimicrobial agent used in the present invention is a composition composed of a naturally extracted compound. It has the function of solving the problem of surface separation by oil and inorganic binding compound, maintaining the strong bonding force with the existing highly hygroscopic resin, and continuing its antibacterial activity until the life of the polymer is over. By generating far infrared rays and negative ions by itself, it binds strongly with the cell membrane possessed by the bacteria itself, destroys the cell membrane itself, and performs sterilization and bacteriolysis while converting it into active oxygen.

The highly hygroscopic resin used in the present invention is a highly hygroscopic resin which acts to delay and suppress the decay of food waste through absorption of a large amount of moisture, and sodium polyacrylate and its derivatives, It absorbs moisture to form a hydrogel, or it is blown up to 1000 times in a snowy solid state to remove the negative wastewater that is present in the food waste, thereby creating a condition in which the microorganism can not live as a source. And this highly hygroscopic resin and natural antibacterial agent are mixed to maximize the anti-decay effect.
