Provided is an eco-friendly disposable cup for beverage takeout, which can be easily assembled and used without a water basin in an office, home, or the like. The disposable cup, on which a lid is formed, has a perforated line formed such that the lid can be inserted into said cup and a hollow pipe formed at the center thereof so as to function as a partition wall between the soil and a reservoir. Further, the cup is formed such that the supplied water in the reservoir can be naturally absorbed through soil pores.
