Method for producing molded products using coffee grounds

A method for producing molded products using coffee grounds, comprising:

• (S1) a step for collecting coffee grounds from coffee shops;
• (S2) a step for drying the collected coffee grounds using a drier or a heating film of higher than 15° C.;
• (S3) a step for sorting granular of coffee grounds so as to remove impurities;
• (S4) a step for grinding the sorted granular into a size of 0.01 mm to 1 mm;
• (S5) a first mixing step in which one or two binding agents of HPC (Hydroxyrpopyl cellulose), HPC-L, CMC-NA (Carboxymethyl celluose sodium), progelatinized starch, Xanthan gum, Povidone, HPMC (Hydroxypropyl methyl cellulose), PVP (Poly vinyl pyrrolidone), sodium silicate, K2SiO3, dextrin Arabia rubber, formaldehyde, vitrified, silicate, shellac, rubber, resinoid, bakelite, rubber, silicate shellac magnesite, and agar powder or starch is added to the ground powder, and 0.01 to 0.5 of the mixture is added and mixed per 1 g of the coffee grounds containing more or less than 20% of moisture and is mixed and pasted;
• (S6) a second mixing step for mixing purified water with the mixture produced in the first mixing step and for pasting the mixture;
• (S7) a step for producing a molded article by compressing and molding by inputting the mixture in a mold;
• (S8) a dry step for drying the molded article which was compressed and molded;
• and
• (S9) a polishing step for polishing the molded product using a polishing agent.
