Abstract

|
|
|
Coffee is a popular beverage not only in Korea but also around the world, and its consumption is on the rise. As coffee consumption increases, coffee waste are also increasing, and recycling is attempted in various fields. However, these recycling methods require complex recycling processes and specialized skills. However, in this study coffee waste, agar powder, and powdered glue were mixed in an appropriate ratio and used as a cement building finishing material. This recycling method has a simple manufacturing method and was shown to improve indoor air quality by delaying radon emitted from cement walls for 2.5 hours with one application and 3.9 hours with two applications. In addition, it was shown that after applying the coffee waste mixture, it was applied twice to close the cracks that occurred during the drying process, thereby prevent the coffee waste from falling off the wall for aesthetic perfection.
