cube coffee ground / recycle of coffee ground

The used coffee ground in a powder form is usually put in a plastic bag or container and used as a dessicating agent or deodorizing agent. Powders make the surrounding area dirty easily, and it is often embarrassing when they are spilt over. I came up with an idea of storing the used coffee ground in the form of cube by compressing it, just like sugar cubes. The used coffee ground in a cube form is easy to store. It can be considered as a new item using coffee, rather than something left over after use.
