Keurig Dr. Pepper unveiled its latest innovation for coffee disks that do away with plastic cups in place of ground coffee, pressed rounds.

The new K-Round coffee pods are made out of coffee and seaweed, but they’ll only work on Keurig’s new Alta coffee maker.

Keurig’s new K-Supreme Plus Smart coffee maker detects which K-Cup pod you are using and adjusts the brew settings for optimal strength and temperature.
