본 발명은 원두커피박(원두커피지꺼기)을 재활용한 친환경 점토 조성물 및 그 제조방법에 관한 것으로, 버려지는 원두커피박을 건조하지 않은 상태에서 바인더, 식품첨가제, 물을 혼합하는 커피 점토 one-step 공정을 이용하여 환경 오염을 방지하고, 향균 탈취제로 활용할 뿐 아니라 환경/미술 교육재료나 수공예품 제작 등에 다양하게 사용이 가능한 원두커피박을 재활용한 친환경 점토 조성물 및 그 제조방법에 관한 것이다.The present invention relates to an eco-friendly clay composition recycling a bean coffee bean (coffee bean coffee bean) and a method for producing the eco-coffee bean recycle. The present invention relates to a coffee clay one-step method for mixing a binder, a food additive, The present invention relates to an eco-friendly clay composition for recycling a coffee bean foil which can be used in various fields such as environment / art education materials and handicrafts production, as well as being used as an anti-bacterial deodorant by using the process.
일반적으로, 커피는 전 세계인의 기호식품으로서 국내에 거의 전량 수입되고 있는 실정이다. 커피의 수입량 증감은 당해 연도의 경제 상황에 따라 변화가 있기는 하지만 수입은 지속적으로 이루어지고 있다. 농림부 유형별 수입통계현황을 살펴보면, 96년에는 58,200톤을 수입하였으며, 그 지출액은 1억4천만달러이다. 또한, 97년에는 전년도보다 증가된 65,000톤을 수입하였으며, 지출액은 2억700만달러였다.In general, coffee is a favorite food of the world, and almost all of it is imported into the country. The increase and decrease of imports of coffee is constant, although there is a change according to the economic situation of the year. According to the Ministry of Agriculture and Forestry 's import statistics, in 1986, 58,200 tons were imported and the expenditure was 140 million dollars. In 1997, the company imported 65,000 tons, up from the previous year, and spent $ 207 million.
이러한 커피의 소비 증가추세에도 불구하고 커피의 공급이 소비에 맞추어 공급되는 이유는 상기 커피가 열대성 식물로 연중 계속하여 생산되는 농산물이므로 원료가 풍부하기 때문이다. 현재 커피의 국내 수입에 따른 지출비용은 막대하며, 커피의 은은한 향과 카페인 중독으로 인해 수입은 계속 증가추세에 있다.Despite the increasing trend of coffee consumption, coffee supply is supplied in accordance with the consumption because the coffee is a crop produced continuously by tropical vegetation and is rich in raw materials. At present, the cost of spending according to the domestic import of coffee is enormous, and the income continues to increase due to the soft aroma of coffee and the addiction to caffeine.
그러나 비교적 고가로 수입되어 판매되고 있는 원두커피는 단지 0.2%만이 커피를 내리는 것에 사용되고 99.8%는 찌꺼기로 버려지며, 한 해 버려지는 원두커피박의 양은 27만톤에 달하는 실정이다. 이러한 원두커피의 사용 후, 재활용으로서 인정될 만한 것은 재떨이, 소형 용기 등에 소량의 원두커피박을 담아 탈취제, 방향제로 사용되고 있는 것이 거의 전부이며, 탈취제, 방향제의 사용 후에도 그대로 버려지게 되는 것이 일반적이다.However, only 0.2% of the coffee beans that are imported and sold at relatively high prices are used for lowering coffee, 99.8% are used for debris, and the amount of coffee beans discarded is about 270,000 tons a year. After the use of such coffee beans, almost all of them that are accepted as recycled are used as deodorants and fragrances by putting a small amount of coffee beans into ashtrays, small containers and the like, and they are generally discarded even after use of deodorant and fragrance.
이렇게 버려진 원두커피박은 음식물 쓰레기로 분류되지 않고 일반 생활 폐기물로 버려져 매립되는데, 이렇게 매립된 원두커피박은 분해되면서 이산화탄소보다 지구온난화에 25배나 안 좋은 영향을 미치는 메탄가스가 다량 발생하여 환경 오염을 일으킬 뿐 아니라 재떨이, 소형 용기에 담아 탈취제, 방향제로 사용하더라도 원두커피박은 쉽게 부패되기 때문에 완전히 건조시키지 않으면 오히려 세균, 곰팡이가 번식하여 악취를 발생시키고 건강에도 안 좋은 영향을 미친다.The abandoned ground coffee bean is not classified as food waste but is buried as general household waste. The burnt ground coffee bean thus decomposes, causing a large amount of methane gas, which has 25 times less effect on global warming than carbon dioxide. However, even if it is used as a deodorant or a fragrance in an ashtray, a small container, the coffee bean pulp is easily corroded, and if it is not completely dried, bacteria and fungi reproduce, causing odor and bad influence on health.
한편, 이렇게 버려진 커피찌꺼기를 수거하여 도 1에 도시된 것과 같이 건조-분별-분쇄 공정 후 가공된 커피찌꺼기를 정제수 및 결합제와 혼합하여 고정틀에 넣어 큐브 형태를 포함한 다양한 형태로 압착 성형하여 성형품을 제작하기 위한 커피찌꺼기를 이용한 성형품 가공 방법(대한민국등록특허공보 제10-1103424호)이 있다. On the other hand, the abandoned coffee grounds are collected and mixed with purified water and a binder in the form of a coffee bean after the drying-fractionation-grinding process as shown in FIG. 1, There is a method of processing a molded product using coffee grounds (Korean Patent Registration No. 10-1103424).
그러나 상기 종래 기술은 원두커피박과 물만으로 점토를 만들기 때문에 성형시 쉽게 뭉개지거나 형태 유지가 어려울 뿐 아니라 원두커피박을 완전히 건조시켜야 하므로 공정시간이 길어 대량 생산이 어려울 뿐 아니라 작업의 효율성이 떨어지는 문제점이 있다. 또한, 상기 공정으로 제조된 성형품은 원두커피박을 완전히 건조하였음에도 불구하고 제품에 곰팡이가 일어나 오히려 혐오감을 일으키고 있다. However, since the above-mentioned prior arts make clay with only coffee bean sponge and water, it is difficult to crumble easily or to maintain shape and to completely dry the coffee bean sponge, so that it is difficult to mass- . In addition, although the molded product manufactured by the above process completely dried the bean coffee bean, the product is likely to be moldy, which is rather disgusting.
이에 본 발명은 건조하지 않은 원두커피박을 그 상태 그대로 사용하는 커피 점토 One-step 방식으로 공정시간이 단축되어 대량 생산이 가능하고, 손에도 묻지 않고, 가공성이 우수하며, 휴대가 간편하고, 원하는 모양으로 쉽게 성형이 가능한 원두커피박을 재활용한 친환경 점토 조성물 및 그 제조방법을 제안하고자 한다.Accordingly, the present invention provides a coffee clay single-step method in which an unhardened ground coffee bean is used as it is in a state of being used, and the process time can be shortened to enable mass production, The present invention relates to an eco-friendly clay composition for recycling a coffee bean that can be easily formed into a shape and a manufacturing method thereof.
