The research was from the concern of the economic growth and people quantity that affects the increase of face mask waste, especially in the pandemic era. “During the research, we use the face mask waste that has been washed with detergent. After it is dried, it burns. The seashells, it is cleaned and finely chopped, and ground. The mixture will be processed with cement and water. Mix it evenly and after that, it is pressed in paving block mold,” Anas, one of the members, said.
