There is no empty T-Disc that would allow you to brew your own coffee. Because Tassimo uses the barcode on the label for brewing instructions, it would be almost impossible to create an empty cartridge you could fill at home since you would need to generate that barcode for brewing instructions.
Single-serve coffee systems are designed to use the pre-packaged coffee module/capsule for the system. A refillable module/capsule is available for a competing single-serve brewing system, but they work poorly. Anyone who has tried it will agree it is a poor solution.
