Description

[Revision according to Rule 26.10.2014] Food waste bag waste food waste composition and food waste waste waste solid composition applied

The present invention is to prevent odors caused by spillage of food wastewater and corruption of food waste containing a large amount of water when processing food recyclable food waste. Food wastes that can easily separate food wastes by keeping solid waste water and food wastes as solid materials at the collection stage so as to physically absorb the waste waters of food wastes by using the composition to be beneficial to the recycling process of food wastes. The present invention relates to a waste paper waste composition and its food waste bag.

In general, food waste appears in various ways.

First sale of food. Food that is discarded in the distribution process, food that is trimmed and discarded in the cooking process, such as homes and restaurants,

Second, it refers to food wastes of agricultural, livestock and aquatic products that are left after eating and discarded after the distribution period.

Third, in the agricultural, livestock, and marine product wholesale markets, there is a part that cannot be eaten during the sale and transportation process.

Fourth, the damaged portion of the food purchased at home, restaurants, etc. occurs, and due to too much diet, leftover food waste is generated.

Fifth, food that has been purchased for longer than necessary, and food that has been stored for too long, and food that has been inadvertently altered, is disposed of as garbage.

The Ministry of Environment data (2000) shows the rate of food waste generation as follows.

Table 1

Food Waste Generation Rate by Source

Sum	home	restaurant	Large Distribution Business (Market, Others)	cafeteria
100%	53%	30%	12%	5%

TABLE 2

Food waste incidence by characteristics

Sum	Vegetables	Fish Meat	Cereals	Fruits
100%	53%	29%	13%	5%

In addition, the economic losses calculated by the Ministry of Environment in 2000 can be confirmed as follows. More than 10 years later, more food waste has occurred, but there is no explosive increase because the population growth rate is not high.

Converting discarded food waste into money amounts to trillions of dollars annually.

It costs more than 400 billion won to dispose of garbage. In particular, since food waste quickly decays, it is expensive to process. Easily recycling discarded food waste into livestock feed can significantly reduce feed grain imports. Korea's food self-sufficiency rate is only 30%, and the dependence on imports of grain for feed is 96%. In 1988, imports of scarce fodder grains cost USD 1.8 billion annually and over 2 trillion won in Korean currency. Needless to say, such food waste leads to higher prices for agricultural, livestock, and fisheries products. There is a need for an easy way to dispose of food waste.

Food waste contains more than 80% moisture and consists of easily charged organic matter. When food waste is disposed of in landfills, odors caused by nitrogen and sulfur compounds and flies. It causes pest breeding such as mosquitoes, and high concentration of leachate generates treatment costs, and it is not limited to waste problems if landfill is mismanaged. Water quality. soil. Groundwater pollution problems also occur. Even when incinerated, the incineration efficiency is lowered due to the low calorie content and high water content of the food waste itself, thereby increasing the possibility of release of various harmful substances due to incomplete combustion.

In general, the food waste treatment process is divided into food waste sources (households and restaurants), collection and transportation (administrative institutions), and final processors (landfill, ocean dumping, feed, fertilizer, fermentation methane, biosolid fuel). In all of these processes, the biggest problem is the odor, discomfort and leakage of wastewater caused by the decay of food waste.

In the case of family homes, the average collection is collected once a week from the administrative agency, so they should be collected at home for a week. In this process, they become corrupted and stink, which prevents them from maintaining a pleasant living environment. In the process, the odor and leakage of effluent are very painful.

In the case of administrative agencies, the pain caused by odors and effluents caused by corruption in the collection and transportation process is severe.

Most of the final processors are fermented to produce methane gas capture, fermented fertilizer, and fermented feed, but there are not many treatment facilities that are actually operated due to bad smell and discomfort. And due to the complaints around the plant is difficult to operate.

According to the 'London Convention', which Korea signed in 1993, all dumping of food waste wastewater has been banned since this year, but there is a shortage of food waste disposal facilities. According to the Seoul Metropolitan Government and various ward offices, private waste disposal companies are demanding an increase in disposal costs due to the ban on dumping of marine wastes. As a result, Seoul's economic burden is increasing by about 50,000 won per ton. Currently, 16 of the 25 wards in Seoul except for 9 wards with waste disposal facilities, including Songpa Dongdaemun Seodaemun Dobong Gangdong-gu, are privately treated. I have used the company.

The government has been able to dispose of trash in the sea since 1988 because of environmental problems such as landfill shortages and bad smells from food waste landfills and groundwater pollution. After joining the 1993 London Convention, dumping of waste at sea continued. Waste dumpers have favored dumping at sea since waste marine discharge costs are up to 90% cheaper than on land. Until last year, companies have dumped food waste wastewater into 125 waters east of Pohang, 63 waters southeast of Ulsan and 200 waters west of Gunsan. The London Convention is an international agreement created to prevent marine pollution from waste dumping. Currently, 87 countries have joined and Korea joined in 1993. Korea is banned from manure and sewage sludge from 2012, food wastewater from 2013, and industrial wastewater and wastewater sludge dumping from 2014. For example, in Seoul, the most populous city, as of 2013, 3347 tons of food waste was discharged each day and 1,800 tons of wastewater was generated. It has handled itself or dumped at sea.

Therefore, the problem of negative wastewater has a problem of developing treatment method.

Sodium polyacrylate derivatives may be used to solidify the wastewater, but the derivatives are used as emulsifiers and thickeners in water-soluble liquids, dispersants in natural or synthetic rubbers, softeners in synthetic fibers, and coagulants, plasticizers, ion exchange resins, It is used as a super absorbent polymer. In the agricultural field, it is used as a gradual release of moisture in the horticultural landscaping field for a long time. In particular, high hygroscopic resins are widely known as compounds that are essential for babies' diapers and women's sanitary napkins.

In 1974, the US Department of Agriculture's Northern Laboratories developed a resin that absorbed 1000 times its absorbency, drawing great attention to its manufacture and application. Contrary to early expectations, however, there was little industrialization other than those used in baby diapers and feminine sanitary napkins. In particular, it is expected to be used for agriculture, but it is not used as much as expected.

This problem has been proposed a waste bag to neutralize the patent registration No. 435130 and absorb the liquid.

The garbage bag contained an absorbent material in which the odor neutralizing composition was deposited, but there was an inconvenience of using a separate garbage bag, and there was a weak absorbency problem.

Therefore, the present invention has been devised in view of the above-mentioned problems of the prior art, and uses the superabsorbent properties of sodium polyacrylate derivatives for food waste decay and easy wastewater treatment. This super-absorbency absorbs all the moisture in the food, absorbs and gels the moisture necessary for the survival of the microorganisms, making the microorganisms unable to live in the food waste. In addition, the food waste negative wastewater solid composition and its foods, which create a condition that prevents the growth and sterilization of bacteria present in the negative wastewater absorbed by the hygroscopic resin using antibacterial agents. The purpose of the present invention is to provide a food waste bag to which the wastewater waste solids composition is applied.

Another purpose is to insert food into food waste bags and use them from home to food waste collection and food waste disposal companies and resource recycling so that the functions are maintained from home to final food waste handlers. Provided is a food waste negative waste solids composition and the food waste negative waste solids composition to which the anti-corruption and effluent leakage is prevented and the odor can be managed in the process of treatment.

As described above, the present invention has the effect of removing the corruption of food waste and leakage of drinking water through the use of the composition of the present invention containing a high hygroscopic resin at home. It eliminates the social problems caused by the economic loss and various complaints caused by the cost of disposing of food waste, thereby reducing the social cost and increasing the ratio of food waste resource recycling from the current 30-40% to more than 90%. have.

The present invention has been shown and described with reference to certain preferred embodiments, but the present invention is not limited to the above-described embodiments and has ordinary skill in the art to which the present invention pertains without departing from the spirit of the present invention. Various changes and modifications may be made by the user.

1 is an explanatory view showing a food waste negative waste solid composition composition envelope according to the present invention,

2 is an explanatory view showing a food waste bag to which food waste negative waste solid composition composition bag according to the present invention is applied;

The present invention is a composition that absorbs all the moisture of food waste with a super absorbent resin to create an environment in which microorganisms cannot grow, thereby solidifying the negative wastewater in the food waste bags to delay corruption.

The present invention is to insert the composition of the present invention into a food waste bag from the home house to pass the food waste to the collection agency in a state that does not rot the waste food waste.

At this time, the composition to be used is a composition mixed with a high hygroscopic resin and wheezing antibacterial agent. As a super hygroscopic resin, it forms a hydrogel using SAP (SuperAbsorbing Polymer), which is widely used in diapers and sanitary napkins, and absorbs moisture from food waste to create an environment where microorganisms cannot live, and is used for cosmetics and containers for food. It contains a composition that prevents the growth of microorganisms and removes more than 99.99% of the microorganisms in the absorbed water using a natural antibacterial agent. Highly hygroscopic resin is a ionic component of sodium substituted with polyacrylate of sodium polyacrylate (cross linked) having a three-dimensional network structure by contact with water attracts water molecules It refers to a polymer structure capable of swelling by retaining moisture in the dimensional network to retain a significant amount of water in the three-dimensional network structure.

The super absorbent polymer (SAP) is sodium polyacrylate, which absorbs 1000 times more distilled water in its own weight, 300 times more water for general tap water, and more urine containing 0.9% NaCl, urea and human waste. Absorb 60 times.

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

The absorption rate of commercially available sodium polyacrylate is different depending on the properties of the product regardless of the average molecular weight of the polymer. That is, depending on the size of the particles, the difference in the amount of moisture and contact area increases. In addition, when the crosslinking density is maintained at an appropriate level, the absorption rate is maximized, and the crosslinking density of the superhygroscopic resin is unconditionally high and the absorption rate is not increased. The strength of the hydrogel depends on how much water is absorbed in the three-dimensional network structure of the hygroscopic resin. The strength of the hydrogel after water absorption of the superhygroscopic resin is not significantly related to the rate of absorption but has a series of relationships with the particle size and shape.

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

The high hygroscopic resin is not particularly limited in its kind in the present invention, and can be used almost all of the sanitary material relations, such as paper diapers, sanitary products, agricultural and horticultural material relations. As a specific example, a polyacrylate crosslinked product, a crosslinked product of a vinyl alcohol-acrylate copolymer, a maleic anhydride polyvinyl alcohol crosslinked product, a crosslinked product of an acrylate-methacrylate copolymer, a methyl acrylate-vinyl acetate copolymer Cross-linked product of a saponified product, cross-linked product of a starch-acrylate graft copolymer, cross-linked product of a saponified product of a starch-acrylonitrile graft copolymer, carboxymethyl cellulose crosslinked product, isobutylene-maleic anhydride copolymer Crosslinked product, isobutylene maleic acid copolymer, polyacrylonitrile polymer, polyethylene oxide crosslinking agent, copolyacrylate salt, polyamide and vinylpyrrolidone copolymer.

In this invention, the said superhygroscopic resin can be used individually or in combination of 2 or more types. In addition, the high hygroscopic resin used in the present invention should have a suitable particle diameter in order to maximize the antibacterial, deodorizing function by contact with air. Specifically, the average particle diameter is usually 5 to 1,000 µm, preferably 20 to 800 µm. If it is less than 5 µm, handling is difficult. If it exceeds 1,000 µm, uniform adsorption of other composition components is difficult and the surface area is reduced, so that more effective absorption, antibacterial and deodorization functions cannot be obtained.

The present invention used a polyacrylate-based superhygroscopic resin using sodium acrylate and tetravalent ammonium salts, which are known as edible, in consideration of recycling of food waste. And its physical properties.

In the present invention, when the food waste is processed, the entire process for the generation, collection and transportation of food waste, and final treatment is all important, and the present invention is not a technology focused on any part but a technology considering the whole process.

In the process of generating food waste, only mechanical methods such as grinding, drying or dehydration were performed. This technique is seen as a technology that is completely independent of the collection and transportation stage as the next process. This is because drying does not decay, but in the actual collection process, the food wastes of various states are mixed and decayed.

In the present invention, because the corruption of food waste is absorbed by the physical method of absorbing moisture and antibacterial, not only in the home but also in the collection and transportation process and the final treatment plant, so that the work can be performed in a state without leakage of negative wastewater. will be.

In order to be used as fertilizer and feed in the final process, it is not affected even if it is used in fertilizer and feed by using small amount of antibacterial agent extracted from natural harmless to human body. And because it uses high hygroscopic resin, it has excellent water-containing properties, and when it is recycled as fertilizer, it has an excellent moisturizing effect on the ground, which can extend the time the fertilizer is absorbed and maintained in the soil and decomposes into monomers that are used for food and have biodegradable performance. It has no effect on soil traits.

When used as a feed, the super absorbent polymers absorb moisture and easily absorb negative waste water by using a composition of super absorbent polymers that maximizes entanglement like gels. It is easy to separate, so there is no problem collecting only food waste and recycling it as feed.

In another final process of manufacturing biosolid fuel, the hygroscopic resin contains an organic compound (sodium polyacrylate and its derivatives) having a high calorific value, thereby increasing the calorific value of the solid fuel.

In the present invention is a diagram for a method for packaging a super-hygroscopic resin for preventing corruption and drinking water leakage used in the food waste bag of Figure 1 in.

The composition used to prevent leakage of effluent and anticorrosion is firstly a metal salt polyacrylate derivative, which is a super absorbent resin that forms a hydrogel to absorb moisture, which absorbs all the moisture of food waste to create an environment in which microorganisms cannot grow. Compound. It is a polymer that has the function of preventing leakage and corruption of drinking water, and the second is the use of natural antibacterial agents used in cosmetics, food containers and household detergents.

Since the antimicrobial agent is permanently adhered to the hygroscopic resin, it can be said to be a component that prevents the growth of microorganisms in drinking water and prevents bacteria from inherent. Depending on the nature of the food waste final treatment process, it may be desirable to treat it selectively. In other words, if the final treatment is incineration, landfill, fertilizer, bio-solid fuel, even if the components of the present invention can be recycled without problems. When used in feed, the composition of the present invention, including negative wastewater, already in the form of solid gel, is easily separated and recycled into feed. In this way, the problem can be solved by selectively performing the final processing.

Therefore, in the present invention, the natural antibacterial agent to be used is a composition composed of extract compounds obtained from nature. Its features are organic and inorganic binding compounds that solve the problem of surface separation, maintain strong binding power with Polymer, a high-hygroscopic resin, and maintain the antimicrobial power until the end of polymer life. It generates negative ions, and binds strongly to the cell membranes of bacteria itself. It destroys the cell membrane itself and converts it into free radicals to act as a bactericidal and bacteriostatic.

In addition, the super absorbent polymer used in the present invention is a super absorbent polymer which has a function of delaying and suppressing the decay of food waste by absorbing a large amount of water, and is a sodium polyacrylate and its derivatives. It absorbs water to make hydrogels or inflate up to 1000 times in the shape of a snowflake to remove the negative wastewater present in food wastes, creating conditions that microorganisms can't live natively. And it is a compound that maximizes the anti-corruption effect by mixing the high hygroscopic resin and natural antibacterial agent.
