At the same time, discarded coffee grounds are recycled to create eco-friendly coffee clay, and coffee clay is used to produce and use various living containers.
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. In general, coffee is a favorite food of people around the world and is almost entirely imported into the country. Although the increase or decrease in the amount of coffee imported varies depending on the economic situation of the year, imports are made continuously.
이러한 커피의 소비 증가 추세에도 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 this increasing trend in coffee consumption, the reason why coffee is supplied in line with consumption is because coffee is a tropical plant and is an agricultural product produced year-round, so raw materials are abundant. Currently, the cost of importing coffee domestically is enormous, and imports continue to increase due to coffee's delicate aroma and caffeine addiction.
그러나 비교적 고가로 수입되어 판매되고 있는 원두커피는 단지 0.2%만이 커피를 내리는 것에 사용되고 99.8%는 찌꺼기(커피박)로 버려지며, 한 해 버려지는 원두 커피박의 양은 27만톤에 달하는 실정이다. However, only 0.2% of the coffee beans that are imported and sold at a relatively high price are used to make coffee, and 99.8% are discarded as grounds (coffee grounds), and the amount of coffee beans discarded each year amounts to 270,000 tons.
이러한 원두커피의 사용 후, 재활용으로서 인정될 만한 것은 재떨이, 소형 용기 등에 소량의 원두 커피박을 담아 탈취제, 방향제로 사용되고 있는 것이 거의 전부이며, 탈취제, 방향제의 사용 후에도 그대로 버려지게 되는 것이 일반적이다.After the use of coffee beans, the only ones that can be recognized as recycling are those that contain a small amount of coffee grounds in ashtrays, small containers, etc. and are used as deodorizers and air fresheners, and it is common that they are discarded as is after use as deodorizers and air fresheners.
이렇게 버려진 원두커피박은 음식물 쓰레기로 분류되지 않고 일반 생활 폐기물로 버려져 매립되는데, 이렇게 매립된 원두 커피박은 분해되면서 이산화탄소보다 지구온난화에 25배나 안 좋은 영향을 미치는 메탄가스가 다량 발생하여 환경 오염을 일으킬 뿐 아니라 재떨이, 소형 용기에 담아 탈취제, 방향제로 사용하더라도 원두 커피박은 쉽게 부패되기 때문에 완전히 건조시키지 않으면 오히려 세균, 곰팡이가 번식하여 악취를 발생시키고 건강에도 안 좋은 영향을 미친다.These discarded coffee beans are not classified as food waste, but are thrown away as general household waste and landfilled. As the landfilled coffee beans decompose, large amounts of methane gas, which has a 25 times worse impact on global warming than carbon dioxide, is generated, which only causes environmental pollution. Even if you put it in an ashtray or a small container and use it as a deodorant or air freshener, coffee bean waste easily rots, so if it is not completely dried, bacteria and mold will grow, creating a bad smell and having a negative impact on your health.
한편, 이렇게 버려진 커피찌꺼기를 수거하여 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 방법이 개시되어 있다. Meanwhile, after collecting the discarded coffee grounds and going through the drying-fractionation-grinding process, the processed coffee grounds are mixed with purified water and a binder, placed in a fixed mold, and pressed and molded into various shapes, including cube shapes, to produce molded products using coffee grounds. A processing method is disclosed.
그러나 상기 종래 특허는 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 있었다. However, since the above-described conventional patent makes clay with only coffee beans and water, it is not only easily crushed during molding or difficult to maintain its shape, but also requires complete drying of the coffee beans, which not only requires a long process time, making mass production difficult, but also reduces work efficiency. There was this.
또한, 상기 공정으로 제조된 성형품은 원두커피박을 완전히 건조하였음에도 불구하고 제품에 곰팡이가 일어나 오히려 혐오감을 일으키는 문제점이 있었다.In addition, the molded product manufactured through the above process had a problem in that even though the coffee beans were completely dried, mold formed on the product, causing disgust.
