Description

A powder cleaner for pre-washing dishes using coffee grounds}

The present invention relates to a powder detergent for washing dishes pretreatment including coffee grounds, and more particularly, to a powder detergent for washing dishes pretreatment using coffee grounds that is environmentally friendly and has excellent cleaning efficiency.

Coffee, which has become an indispensable favorite food in the daily life of modern people, according to a survey, is that Korean office workers drink two cups of coffee on average a day. The scale of the domestic coffee market reached 7 trillion won as of 2018, and reached 2000 trillion won worldwide.

To make coffee, green beans, the seeds of the coffee tree, are roasted, which are called beans. Coffee is extracted from these beans. However, coffee grounds (coffee leaves) come out here, and only 0.2% of the beans are used when making a cup of coffee, and the remaining 99.8% is discarded.

More than 10 million tons of coffee waste are issued worldwide each year, and about 107,000 tons of coffee waste were generated in Korea as of 2014. And these are mostly buried in the ground. When coffee grounds are buried in the ground, the soil is contaminated with caffeine, and methane gas and carbon dioxide, which are the main causes of global warming, are generated.

About 338 kg of carbon dioxide is produced per ton of coffee grounds. 92,000 tonnes of carbon dioxide are produced annually, which is similar to the amount emitted by 11,000 cars. So, in many studies, there are many concerns and attempts on the use of coffee grounds that cause serious environmental problems.
