An environment-friendly card is disclosed in the invention, characterized in that a card of a predetermined thickness is fabricated from using a predetermined proportion of polylactic acid-containing composite materials; the card may be applied for multiple purposes due to the flexibility, physical property, and mechanical property of the decomposable composite materials, and may replace petrochemistry polymers that are used to make conventional cards. The decomposable composite materials may decompose naturally or be burned in an incinerator and only gives off water and carbon dioxide after disposal, and is non-polluting because the composite materials may be recycled. As a result, the card may alleviate the problem of environmental pollution and thus is environment-friendly.
