In general, brick is a building material baked at high temperature with clay as the main raw material, and is classified into ordinary brick, wollastonite brick, refractory brick, and fireproof brick according to materials, firing conditions, and uses. In particular, cement bricks are manufactured by kneading portland cement, sand, and gravel with water, then mixing, compressing and shaping them, which are known to be harmful to the environment because they emit large amounts of carbon dioxide (CO ₂ ) and greenhouse gases into the atmosphere during the manufacturing process. . Accordingly, there have been attempts to overcome the problems by using ocher, briquettes, cypress, and environmentally friendly materials.

On the other hand, as the consumption of Italian authentic coffee extracted at high temperature and high pressure in coffee beans that have been crushed and roasted recently roasted coffee beans is increasing, interest in various applications of coffee is increasing. Coffee is a versatile fruit because it has insect repellent, antiseptic, and deodorant properties. In addition, since coffee is neutral, it has a property of being resistant to alkali and acidity, and thus can be blended well with any material. In addition, the coffee beans are discarded after being selected during the whole roasting process, and are incinerated or landfilled because they cannot be recycled. There are a number of conventional techniques for solving the problems related to mass disposal of such existing waste coffee material. Japanese Patent Application Laid-Open No. 05-277460 has the advantage of reducing the amount of waste coffee material to be discarded by blending a polymer into coffee foil and molding it according to various molding methods of rubber or plastic, but the range of application is limited. Because of this, there is a problem that waste coffee materials still have to be disposed of in large quantities.

Conventional techniques using coffee that can solve the above problems include those related to ceramics, composite boards, block boards, and artificial marble, but there is no prior art regarding bricks using coffee. As mentioned above, since the bricks have many harmful components in the manufacturing process, there is a need to manufacture bricks by recycling environmentally friendly materials such as waste coffee materials.
