Microbial Community Analyses Composition for Food-waste Vanishment and Application Thereof}

The present invention relates to a bactericidal bacterium composition for extinction of food waste and its application, and more particularly, to a composition for extinction of food waste, comprising: a microbial bacterium composition for extinction of food waste including microorganisms and subsidiary materials and the microorganism. And it relates to a decomposing bacterial composition and the application thereof for the extinction of food waste that can extinguish food waste by injecting and reacting food waste in the composition comprising the subsidiary material.

Looking at the trend of the generation of food waste of household waste from 1996 to 2007 is shown in Table 1. Since 1997, when the national economic crisis began, the amount of food waste generated has decreased considerably, and since then, it has maintained a constant level and has increased again since 2004. Occurred.

Meanwhile, looking at the status of food waste generated by local governments in 2007 are shown in Table 2 below. Seoul accounted for the largest share at 23.2%, followed by Gyeonggi-do at 22.0%. The generation of these two municipalities accounts for almost half of the total. In other municipalities, the share of total generation is significantly lower than these two municipalities. The third municipality that produces the most waste is Gyeongsangnam-do, which accounts for only 6.3% of the total.

Food Waste Generation and Ratio by Local Governments Per attempt Generation amount (ton / day) ratio(%) Per attempt Generation amount (ton / day) ratio(%) Nationwide 14,452 100.0 - - - Seoul 3,352 23.2 Gangwon 477 3.3 Busan 841 5.8 Chungbuk 374 2.6 Dae-gu 766 5.3 Chungnam 557 3.9 Incheon 738 5.1 Jeonbuk 595 4.1 Gwangju 484 3.3 Jeonnam 519 3.6 Daejeon 507 3.5 Gyeongbuk 622 4.3 Ulsan 345 2.4 Gyeongnam 912 6.3 game 3,175 22.0 Jeju 188 1.3

Table 3 shows the trend of food waste generation by year from 1996 to 2007 of major local governments. In the case of Seoul, the amount of waste generated was similar to that of the entire generation, and the amount of waste generated from 1996 to 1998 remained at a certain level but increased slightly in 2006. In addition, Gyeonggi-do showed a steady increase after a slight decrease from 1996 to 1998. On the other hand, Gyeonggi-do has been showing a small but steady decline in recent years.

Looking at the generation of food waste on the basis of the amount of daily waste generated per person as the discharge amount of food waste in 2006 as shown in Table 4 below. It was four times higher for non-homes (571.5g / day for 1 day) than for households (142.1g / day for 1 day). In particular, restaurants (1,835g / 1 person per day) and accommodation (1,100.5g / 1 person per day) were very high. This is 7 to 13 times higher than the average of households and 2-3 times higher than the average of non-family members.

Looking at the types of food waste, vegetables and fruits accounted for 55.5% (184.6 g / day, 1 day), and grains accounted for 19.5%. Even the restaurants that produce the most trash do not deviate significantly from this overall trend. Vegetables and fruits were the highest at 50.2%, followed by grain at 18.7%.

According to the Ministry of Environment's request for research services from the Korea Food Development Institute, the annual economic value of food waste is 15 trillion won. In other words, a single Korean citizen throws away 314,000 won worth a year. Considering Korea's food independence, which relies on imports for about 70% of its total grain consumption, it is a waste of valuable foreign currency.

Most food wastes generated in Korea are reported to be recycled. In 2007, the majority of recycled waste was 92.2%, while incineration and landfill were 4.7% and 3.1%. However, this phenomenon has occurred in the past few years due to the sharp decrease in the proportion of the treatment results other than recycling. In particular, the share of landfills, which accounted for 92.8% of the total in 1996, dropped sharply to 3.1% in 2007 [see Table 5].

It is reported that food waste is mainly recycled by means of feed or compost production. In 2006, 45.2% of the emissions were used as feed and 44.9% as compost. Compared to 2001, the share of feed decreased slightly, while the compost increased slightly (see Table 6).

It is hard to find such a case in the world that the installation and operation of a large number of resources facilities in such a short period greatly increased the food waste recycling rate. These remarkable results suggest that the primary challenge of refining food wastes has been resolved to some extent, but the problems that should not be overlooked coexist (see Table 7).

Until now, the disposal of food waste has been prohibited from landfilling in the administrative districts beyond the city, and incineration has been carried out in a very small amount because the cost is excessive and practically reduced. Nowadays, separate collection is well performed, and the solids are recycled as compost raw materials or dry feeds through sorting, crushing, and dehydration, mainly in intermediate treatment companies. Is being processed in a way.

However, dumping at sea has become a major culprit of environmental pollution in the sea, and its severity is on the rise. So now, we are devising treatment methods to obtain methane gas by using liquid desorbent to obtain renewable energy.However, the initial investment cost is enormous and requires a lot of operational technical factors. Other than the facility, the situation is not good enough. In addition, the operation is unstable due to operational difficulties, and it is possible to obtain methane gas, but Korea is a country with four seasons, and seasonal gas generation is also large. There is not enough gas. In addition, the effectiveness of the digestive fluid after anaerobic digestion is greatly reduced due to the cost involved in the second subsequent treatment. In summary, the energyification technology after anaerobic digestion of methanol desorption of food waste degreasing solution is insufficient in the absence of technical know-how.

The problem of feed is unstable, coupled with the livestock wave problem. In today's large-scale livestock farms, such as cow mad cow disease, swine cholera and wasting disease syndrome, and bird flu in chickens, the continued use of liquid foods that have dried or sterilized food waste, although its stability has been proven, is a psychological barrier to its use. High. Currently, farmers collect them immediately from relatively safe places, such as school meal centers, military units, and workplace meal centers, or intermediate processors supply them to farmers free of charge. However, they are used only by very few hog farmers. In the simple drying method, research on the development of food feed technology remaining in food waste was intensively conducted in the mid to late 1990s, representing the 1997 to early 2000. Created. The report concluded that even simple dried food wastes would be equivalent and excellent when used as additives. However, due to the shrinking demand for recycled products, such as foot-and-mouth disease and mad cow disease, food leftovers failed to spread and farmers' perceptions changed very negatively. Since then, nearly 10 years have passed without the production of such research or products. In most cases, the dried and fed feed has not been found and is sent back to compost. In Korea, there are many uses in small-scale farms through wet fermentation of food waste. However, wet fermentation is difficult to store for a long time, the smell of the user is only a very small situation.

Although composting is easy for the technical factor, the odor is most severely generated next to the compost because it does not mix enough excipients and does not meet the period of stay. The composting process is also a serious problem because it is properly mixed with quicklime and taken out. Only 38.6% of the total production of feed and compost was paid at food waste recycling facilities. In particular, about 45.5% of the food leftovers are self-used, and free food is the most common at 61.4%.

If so, we face the urgent need to find ways to fundamentally block the environmental pollution caused by this food waste and find ways to avoid secondary problems caused by subsequent resourceization (compost, feed, etc.).

Accordingly, the present invention intends to treat organic wastes including food waste using an extinction method.

The basic concept of the extinction method used in the present invention is to use a large amount of aerobic high-temperature Bacillus microorganisms that have previously activated organic materials such as food waste and organic waste (sludge, food waste, animal and plant by-products) It is a method of extinguishing the remaining amount of the input at all. The complete aerobic decomposition results in no accumulation of by-products and the reduction of odors, making it the most environmentally friendly way to treat organic wastes, including food waste.

Bacterial 4 had no additional food waste, so the fungus itself was digested and the temperature decreased.

Bacterial 1 had less food waste input than the digestive power (dissipation capacity) of the food waste, so it was observed that even the fungus itself was digested and reduced little by little, and it was observed that the degree of exotherm decreases with time as heat is taken out. Could.

Bacterial 3 seemed to decompose all doses at the beginning, but after 20 days, food waste gradually accumulated and accumulated. In addition, incomplete digestion caused odors, flies swelled and maggots occurred.

Bacterial 2 was a food waste dose and the amount of digestion of food waste by the decomposed bacteria composition was balanced in the course of a month of experiments was observed that the food waste administered to the decomposed bacteria composition consistently without significant change.

The observed characteristics according to the mixing ratio of the decomposition bacteria composition and food waste input amount for Table 11 are summarized in Table 12 below.

Observed Characteristics According to the Mixing Ratio of Degraded Bacteria Composition and Food Waste Input Experimental Section Normal: Food waste input (V / W) Characteristic Fungus 1 100: 1 As the energy source is less than the decomposition ability of the fungus, the fungus self-extinguishment occurs. Homogenous drying occurs easily. Normal 2 50: 1 The bactericidal decomposition ability and the amount of food waste input coincide. Stable system. Fungus 3 25: 1 Decay occurs due to exceeding the degrading capacity of the bacterium. Odor Occurred. Maggots occur.

As shown in the results of Table 11 and Table 12, the decomposition efficiency of the food waste was excellent when using the decomposing bacterium composition of 50 times the volume of food waste, and showed the digestive ability to extinguish all the food waste administered daily. When using the decomposing bacterial composition, the dose of food waste was higher than the digestive capacity, and it was confirmed that food waste gradually accumulated. Therefore, although the high activity of the high-temperature aerobic Bacillus bacteria were initially present, the amount of microorganisms that limit the ability to continuously decompose the sense of the microorganisms are limited, complete aerobic digestion does not occur, incomplete fermentation and decay occurs, resulting in odor. .

* In Table 13 above, Zone 1 is the midpoint of the distance from the center of the disintegrating fungal composition to the end of the composition, Zone 2 is a point 90 ° from Zone 1, Zone 3 is a point 180 ° from Zone 1, and 4 Zone is a point 270 ° from Zone 1.

As shown in the above Table 13, the volume of food waste of about 300kg to 1,000kg per day is continuously 50m ³ . As a result of the addition to the decomposition bacteria composition, due to the high temperature aerobic digestion heat, the temperature of the decomposition bacteria composition was kept constant around 70 ℃ regardless of the room temperature. Accumulation of food waste was not observed and the volume of the decomposing bacteria composition was maintained almost intact. Therefore, it can be inferred that the input food wastes are all energized by the microorganisms of the decomposition bacteria composition and exothermic reaction occurs due to metabolic heat. there was. The amount of food waste that has been extinguished for one month amounts to about 13 tons, so that the degradation bacterial composition of the present invention is effective for extinction of food waste.

On the other hand, it was easily sensed that the odor of the food waste that was slightly spoiled and mixed with the decomposing bacterium composition and faded at the same time. Odors of food waste are various organic acids (propioic acid, butyric acid, iso-butyrate, valerate, iso-valerate) that are released as sugars decay, and are easily decomposed into carbon dioxide and water because they are good nutrients for high temperature microorganisms. In addition, ammonia can be easily collected and dissolved in the decomposed bacterial composition having a water content of about 40% and readily used as a nitrogen source. In addition, hydrogen sulfide and mercaptans, which are strong odorous sulfur-containing gases, can also be used as nutrients to microorganisms, so that odors can be essentially eliminated by microorganisms. In addition, leachate did not come out at all, and due to the high temperature digestion of the fungi, all of them were vaporized, and the fungus was dried.

As described above, it can be observed that the method of extinction of food waste by the decomposing bacterial composition of the present invention does not cause any problems of strong odor or leachate generated during composting of food waste.
