The ashtray made from coffee grounds has the function of deodorizing.

Coffee grounds have the ability to absorb odors and are good helpers for deodorization. Coffee grounds can be put in a small plate and put in the toilet to remove the smell, or they can be sewn in a cloth bag and stuffed into the shoe cabinet, which can not only serve as an aromatic agent, but also play a role in dehumidification, and the deodorization effect is more obvious if it is put in the shoes. Putting coffee grounds in an ashtray can remove the stench of smoke and make it easier to extinguish cigarette butts. Designer Ryohei Yoshiyuki takes advantage of the deodorization function of coffee grounds, using coffee grounds to design this ashtray to remove the smell of smoke and make it easier to extinguish cigarette butts. Living at home, if there are family members smoking, we can also spread some coffee grounds in the ashtray, the effect is absolutely good.
