Abstract

The disclosure provides eco-friendly synthetic wood containing coffee grounds, which uses, as main components, coffee grounds and waste gypsum, which are waste resources, and PETG recycled from waste plastic, thereby contributing to protection of the environment, and which enhances formability, post-processability, and a weather resistance of the synthetic wood by reducing a ratio of shrinking-swelling and a water absorption factor of the synthetic wood, and a manufacturing method thereof.
