Coffee grounds also have creative new uses.

Many people like to drink coffee these days, but few people know that for every 350 ml cup of freshly ground coffee, about 20 grams of coffee grounds are produced. When coffee grounds are discarded, landfilled or incinerated with other waste, they increase the cost of waste disposal and exacerbate the planet's greenhouse effect. Xingeng Workshop, a social organization located in Changhe Public Welfare Square, Shuangta Street, Gusu District, has its own set of tricks for dealing with coffee grounds.

Recently, Xingeng Workshop joined hands with youth members of Shuangta Street to launch a "coffee grounds graffiti" contest. They first carefully draw the outline with pencil on white paper, then brush the white glue with a small brush at the line, evenly sprinkle coffee grounds, and finally gently press and shake, so that the coffee grounds without white glue fall off, and a simple coffee grounds sand painting is born. Although it sounds easy, it is not easy to draw well. First, the lines of white glue should be evenly coated, and the coffee grounds should be coated on the edge of the glue, so as not to deteriorate the adhesion of white glue when it dries. Of course, the most important thing is to have good creative composition.

For coffee residue sand painting, everyone thinks it is quite interesting. In just two hours, more than 20 coffee grounds sand paintings appeared on the paper. It is reported that in addition to painting, coffee grounds can also be used for potted plant fertilization, as well as kitchen toilet odor absorption and strong decontamination. They hope to use coffee grounds sand painting activities as a platform to let more people understand the various wonderful uses of coffee grounds and work hard to practice them in their lives.
